Introduction

Information Technology as a service has moved from concept to reality. Early adopters havealready deployed major solutions, and it has become a standard objective for mainstream InformationTechnology (IT) architects and planners. HP has adopted the term Converged Infrastructure todescribe how HP products and services can address this approach. This Reference Architecture guideprovides a business and technical view of the adoption process.

Todays IT stakes are larger than applications and platforms. They span the data center, fromcapacity to technology, processes, people, and governance. HP Converged Infrastructure opens thedoor to new approaches, and can enable IT management to defer or avoid costly data centerexpansions. For example:

Simplification: Collapse siloed, hierarchical, point to point infrastructure into an easily managed,energy-efficient, and re-usable set of resources.

Enabling growth: Efficiently deploy new applications and services, with optimum utilization acrossservers, storage, networking, and power.

On-demand delivery: Deliver applications and services through a common framework that canleverage on-premise, private cloud, and off-premise resources.

Employee productivity: Move human capital from operations to innovation by increasingautomation of application, infrastructure, and facility management.

HP Converged Infrastructure enables organizations to achieve these goals while getting ahead of thegrowth curve and the cost curve. Figure 1 illustrates how HP Converged Infrastructure transforms thetraditional data center into a unified, flexible resource for business.

Attaining this goal is achievable today, with this guide as the roadmap. Configurations based on HPBladeSystem c-Class, Superdome 2, HP StorageWorks, and HP Intelligent Resilient Frameworkprovide a flat network and resource pool suitable for the enterprise. In the section ConvergedInfrastructure Reference Architectures these building blocks and others are assembled to address keyenterprise workloads. This HP Converged Infrastructure architecture can be deployed with theapproach taken by HP IT internally, and large HP customers:

1. Start from existing investments, whether from HP or others.2. Extend those investments with standards-based components and building blocks from HP that have

already been designed to support a single pane of glass management philosophy.

3. Pool those resources for allocation as needed, when needed adjusting to business requirements.4. Converge the infrastructure while sticking to your priorities. HP already works with major vendors

to verify that their application, operating system, virtualization and other products can bemanaged and optimized.

This sequence of this guide addresses the information needed by key IT stakeholders across theproject lifecycle; starting with planning, then building, and finally running infrastructure.

The Business Value of Converged Infrastructure provides senior managers and planners with a lookat how HP Converged Infrastructure solves real business problems today. It is also useful to IT

management and staff, as it frames the business objectives that technology must address.HP Converged Infrastructure Technology Foundation describes the core elements and architecturalprinciples. It provides architects and designers with functional descriptions as well as a discussion ofthe HP Converged Infrastructure Maturity Model, and how the model accelerates IT results.

HP Converged Infrastructure Reference Architectures provides real instances of HP ConvergedInfrastructure. It starts with the core Converged Infrastructure architecture, and then builds withfunctional architecture, product mappings, and deployable, application-specific configurations.Deployment and operations specialists can use it as their initial reference when considering solutionalternatives for upgrading or transforming data center capabilities.

Along with this comprehensive Converged Infrastructure model, HP offers tools, services, andworkshops to support well-informed decisions. For example:

The HP Converged Infrastructure Maturity Model can help you assess the current and desired futurestate of your data center infrastructure, people, processes and governance. The result is acustomized, action-oriented, high-level roadmap for structured improvement.

Data Center Transformation workshops can help define projects in the areas of consolidation,energy & space efficiency, automation, and business continuity & availability.

HP Application Modernization solutions can help visualize legacy application evolution. Thiscreates opportunities for infrastructure renewal and determines the right legacy applicationtransformation strategy for the business.

Proven Private Cloud and Enterprise Services that can help design, build, manage, and run theconverged infrastructure.

HP Financial Services are available to transition from existing technology, acquire new solutions,manage those solutions through the lifecycle, and then retire technology. HP Financial Services canalso show how HP Converged Infrastructure can reduce capital expenses.

Regardless of where an organization is in this process, HP Converged Infrastructure can be deliveredas needed and at the required pace. It provides a solid foundation for real IT solutions, and an ITapproach that extends the life of the data center, while enhancing agility and business value.

The Business Value of Converged Infrastructure

The Opportunity

Infrastructure convergence has emerged as possibly the most important trend in decades creating amass ripple effect that has brought our industry to a major inflection point in how we approach IT. Intodays business landscape, everything is accelerated and exponential across users,competitors, internal organizations, investors, and on and on. The value of IT or Data Center

convergence has far reaching benefits across all these communities.

Your business customers expect IT costs and resources to be in-line with the business cost envelopewhile ensuring tighter compliance amidst tougher regulations. They also demand rapid IT results notweeks or months, but days, hours, or even minutes. And they want all this with functionality, qualityand security, and the option to change/add resources on demand.

Taken together, these incremental investments are forcing hard customer decisions on how to extendthe life of the data center. The cost of any individual application pales against the cost of moving orexpanding a data center. HP Converged Infrastructure delivers technical innovation by collapsinginfrastructure and related costs and potentially avoiding or deferring on-premise facility investments.

Restructuring around services

In addition to addressing issues in the data center itself, IT needs to be able to freely and cost-effectively innovate for business advantage. Its no longer about being an efficient world-class ITorganization, rather about being a true partner in the business responding quickly to businessdemands and bringing in new innovation for growth. IT becomes a service broker, building a servicedelivery channel that can match SLAs and the choice of services to the desired business outcomes foreach customer.

Unfortunately, change does not usually happen easily. IT Sprawl is real: resources that are tangled upin legacy applications and architecture silos that demand dedicated infrastructure. Add in the newwave of applications social networking, mobility, media, etc. - yet another set of unique andmanually provisioned applications.

Because of IT sprawl, most organizations are spending upwards of 70% of the IT budget onoperational costs while business innovation is throttled down to 30%. Even worse, about half of this30% is allocated to application upgrade cycles. That leaves only about 15% of the budget for trueinnovation.

The bottom line: It has never been more strategic or critical to rethink and transform the data center.Innovation is an imperative for business and IT to survive and thrive.

Convergence delivers a services-oriented infrastructure so that IT organizations can reallocate staffresources from operations to innovation. HP Converged Infrastructure gives you rapid provisioningand flexible resourcing to match IT supply with fluctuating demand. It frees-up funds trapped inoperations to reduce the burden of legacy and mission critical systems and reclaims the funds forinnovation. Adopting the HP Converged Infrastructure Maturity Model as a roadmap to renewing

data center operational skills can provide a huge execution advantage, as well as lead toimprovements that extend the life of the data center. It covers a broad range of capabilities, as shownbelow.

Where the savings come from

HP Converged Infrastructure can help businesses overcome the confines of IT sprawl and shiftresources from operations to innovation. HP Converged Infrastructure delivers the data center of thefuture, today. The foundation technologies described later in this guide have all been built withconvergence in mind. They all reflect industry standards, leadership intellectual property, openness,and of course, customer choice. These result in fundamentally lower costs, and a lot less infrastructureHere a few of the many examples of how HP solutions can simplify your data center and deliver thecost savings with which to fund innovation:

HP Intelligent Resilient Framework merges standalone switches to form a flat, unified fabric,eliminating hops and packets by the billions.

HP Virtual Connect FlexFabric reduces server edge infrastructure by 95%. Virtualized I/O reducesthe need for large numbers of high-bandwidth connections while providing better performance.

HP Integrity servers provide 2-1 core count consolidation over older servers, and each core cansupport up to 20 virtual machines. Racks of test and development servers simply disappear.

HP Insight Dynamics lets you do drag and drop provisioning of complex, multi-tier applications. Cutyour provisioning time and errors by a factor of 10.

HP Intelligent Power Distribution reports the power you actually use, device by device. DynamicPower Capping can reduce infrastructure power cost per server up to 69%.

With HP Converged Infrastructure, you get a unified, service-ready, and shared infrastructure that candynamically orchestrate and provision server, storage, and networking efficiently. As resources areallocated for specific workloads, they are also rapidly scalable and optimized for energy-efficiency,high availability and utilization. The bottom line is extending the life of the data center. This meansdelivering more business value, while using less infrastructure, and power, and investing more ininnovation instead of operations.

HP Converged Infrastructure Technology Foundation

This section covers the basic design architecture of the converged infrastructure data center, based onHP developed models and available HP and partner technologies. This is followed by a description ofthe HP Converged Infrastructure approach. The functional shared service capabilities of HPConverged Infrastructure provide the foundation for architecting and evolving data centerinfrastructure based on best practices developed from decades of successful data centertransformation and shared service deployments implemented by HP professionals.

Design Principles for the Data Center of the Future

The solution to IT sprawl is to break down the technology silos and bring all compute, storage, andnetworking resources together as a common pool. Resources can then be dynamically provisionedand shared by many applications and managed as a service. This approach brings togethermanagement tools, policies, and processes so that resources and applications are managed in aholistic, integrated manner. It also brings together power and cooling management capabilities sosystems and facilities work together to extend the life of the data center.

The HP Converged Infrastructure has five overarching design principles that are important to IT andtogether enable the data center of the future. The infrastructure must be virtualized, resilient,

orchestrated, open, and modular. Each is described briefly below and then detailed through theremainder of this section.

Virtualized

HP Converged Infrastructure benefits from the virtualization of resources: compute, storage,networking, applications, and operating systems. Virtualization provides an abstraction layer betweenthe physical and the logical, making it easier and faster to reallocate resources to match the changingperformance, throughput, and capacity needs of individual applications. This end-to-end virtualizationimproves IT flexibility and response to business requests, improving business speed and agility.

Virtualization covers all key aspects of the infrastructure. This includes client desktops, networking,servers, memory, and storage.

Specific aspects of virtualization include: Compute resources. Pools of modular server resources which can be virtualized using technologies

such as VMware vSphere, Microsoft Hyper-V, and HP Integrity Virtual Machines.

Storage resources. Storage that is virtualized at the array, network, and file system level enableshigher utilization of existing capacity, eliminates stranded capacity, enables tiering which lowerscosts for new capacity, and provides a non-disruptive way to respond to data growth.

Network resources. Virtualized networks provide the ability to quickly provision service-specificclassification and prioritization based on the physical and virtual workloads from the entrance pointof the physical or virtual server edge extended throughout the network fabric to ensure consistentapplication end-user experience. This approach enables simplified, consistent service delivery andimproved business agility. Virtualized configuration and management of the extended network to

increase performance through higher utilization. Reduce the cost of network operations by reducingcabling-related provisioning costs and downtime.

Resilient

HP Converged Infrastructure integrates fault tolerant mission-critical technologies and high availabilitypolicies. Because diverse applications share virtualized resource pools, the infrastructure must havean operating environment that automates high-availability policies to meet SLAs and provides the rightlevel of availability for each business application.


9/71

Security is also a key enabler of resiliency; the infrastructure must support policy-based securitymodels, continuous intrusion prevention, and automated updating of security solutions. It must ensurethe integrity and availability of applications, systems, and data with security solutions that are unifiedacross physical and virtual server domains. This is essential to ensure threats can be blocked beforethey can proliferate over the network.

Resiliency is derived from the compute, storage and network resources and processes that providefailover, high availability and disaster recovery based on business requirements.

OrchestratedHP Converged Infrastructure orchestrates the requests of the applications, data, and infrastructure,defining the policies and service levels through automated workflows, provisioning, and changemanagement. Orchestration provides an application-aligned infrastructure that can be scaled up ordown based on the needs of each application. Orchestration also provides centralized managementof the resource pool and facilities, including billing, metering, and chargeback for consumption.

For example, orchestration should reduce the time and effort for deploying multiple instances of asingle application. In addition, as the requirement for more resources or a new application istriggered, automated tools perform tasks that before could only be done by multiple administratorsoperating on their individual piece of the physical stack.

Open

HP Converged Infrastructure is based on industry standard technologies. This ensures customers canleverage existing investments as part of the consolidation and convergence process. Industrystandards enable customers to adopt new technologies incrementally and at their own pace, andprovide the technology openness they require to incorporate heterogeneous infrastructure.

Modular

HP Converged Infrastructure is built on modular design principles based on open standards, allowingfor interoperability. The modular approach allows IT to integrate new technologies with existinginvestments, and provides infrastructure extensibility for the future.

The modular approach should remain open, so that special-purpose or existing infrastructureinvestments from multiple vendors can be managed under a common umbrella, and share resources

with other elements of the pool.

Theory to Practice: Functional Description of HP Converged Infrastructure

HP Converged Infrastructure embodies the design criteria outlined above and integrates a rich set oftechnologies into a seamless, standards-based infrastructure. This approach enables IT organizationsto deploy applications with minimal constraints on best of breed infrastructure technologies. The HPConverged Infrastructure architecture stack is illustrated below and includes three categories ofproducts:

Core products that is essential to delivery of Converged Infrastructure services. These productsprovide the glue which enables rapid, virtualized, application deployment.

Supporting products that can be deployed in standalone configurations. These products have beendesigned to take full advantage of shared service capabilities.

Complementary products such as those from third party providers. HP Converged Infrastructureprovides solid interoperability with, and management of, complementary products.

Resource Supply: HP Virtual Resource Pools

HP Virtual Resource Pools are derived from common modular infrastructure that enables the creationof shared capacity that can be combined, divided, and repurposed to match application demand

more effectively. Using HP Converged Infrastructure, IT organizations can support business usersthrough a common pool of virtualized resources that can are configured on the fly for differentneeds: e.g. core business, shared services, mission critical, cloud, and high-performance computing(HPC) applications. HP Virtual Resource Pools leverage the innovative capabilities of servers, storage,mission-critical systems, and scale-out technologies across the HP ProLiant, Integrity, Integrity NonStop,and StorageWorks portfolios. The resources can be provisioned to support third party virtualizationenvironments such as VMware and Microsoft, as well as HP solutions such as HP Integrity VirtualMachines.

Business Challenge

While server virtualization has become widely adopted, there is still much efficiency to be gained by

applying the lessons learned to other areas of the physical infrastructure. In addition, the adoption ofvirtual machine technology has begun to lead to Virtual IT Sprawl where machine images arecreated indiscriminately and without a clear resource strategy.

Some specific server and storage challenges include:

Improve time to deployment and reduce wasted capacity.Adhere to Service Level Agreement metrics such as response time, maintenance windows, and

application availability.

Address power and cooling challenges as well as substantial facilities costs.

Reduce capital and operational costs. Reduce the impact of data growth on storage investment for traditional and emerging data types. Improve business continuity and availability for critical applications. Simplify the deployment of storage for business applications. Reduce wasted capacity and isolated, independent data repositories.Considerations and best practices:

There are many best practices to consider when moving from isolated islands of compute and storagetowards virtual pools of capacity. When evaluating server virtualization it is important to:

Make compute resources available as either virtual or physical resources. Provide a mix of resources to maximize deployment efficiency AND meet business needs. Leverage hypervisors to distribute workloads efficiently and rapidly.Apply templates to ensure consistent deployment images for replicated workloads.Some additional considerations apply when eliminating stranded storage capacity:

Utilize shared storage such as Network Attached Storage (NAS) or Storage Area Network (SAN)unless application specific requirements indicate otherwise.

Consider storage virtualization technologies to improve utilization and enable granular pay as yougrow investments that are non-disruptive.

Leverage management tools to automate storage provisioning, reduce operational costs, andprovide storage provisioning consistency.

Tier storage to improve ROI of storage investments.HP Converged Infrastructure Solution

Power and Facilities Management: HP Data Center Smart Grid

A data center is a highly complex ecosystem filled with IT hardware and racks, connected by miles ofwires and cables, with complex relationships between hardware and software. It intersects withanother complex system, the data center facility itself, which delivers power, cooling and floor spacefor IT. For reliability and availability, both infrastructure and the facility are usually over-provisioned.

A fixed energy and cooling buffer is usually allotted to make sure that critical peaks of IT usage donot result in IT meltdowns. Plus, power and cooling is fixed, usually supplying a constant amount toITno matter the data center status or workload.

Business Challenge

In most ways, power usage in current data centers is provisioned in an identical manner to computeand storage: sized for peak, and typically largely underutilized. It is also difficult to track andmanage, leading to accidental shutdowns of critical resources.

Over-provisioning leads to several major issues:

Power distribution infrastructure costs are increased. Data centers can be rated as out of capacity well before actual physical limits are reached. Cooling is over-delivered, increasing cooling plant and utility costs.Individual infrastructure components also contribute to excess power usage:

Inefficient power supplies. Limited control over fans or power to processors, memory, storage, and network devices.Considerations and best practices

Map and monitor power consumption to rack capacity. Manage power consumption to reflect changing infrastructure power needs. Use a TCO model to understand the cost of powering and cooling of servers, both existing and

future systems.

Map, monitor and manage facility cooling to match infrastructure cooling needs.When planning server deployments, dont use device power consumption estimates. Understandactual usage where possible, which is not always reflected in nameplate specifications. HP

equipment will tell you exactly how much power is being consumed and lets you control power useaccordingly.

Tightly manage power delivery configurations to eliminate errors during configuration changes. Understand data center thermal trends and airflow. Deploy shutdown procedures that prioritize availability for mission-critical applications. Have a plan

for infrastructure failure and maintenance planning.

HP Converged Infrastructure Solution

HP Data Center Smart Grid integrates environmental management, facilities management, and system

management. It creates an intelligent, energy-aware environment across the infrastructure andfacilities to optimize and adapt energy usage, to reclaim facility capacity, and to reduce energycosts. HP Data Center Smart Grid collects and communicates thousands of power and coolingmeasurements across systems and facilities in real time, giving your organization greater insight andcontrol over energy use. This lets you support business growth by deploying more infrastructure withinthe same data center footprint, hosting more applications and making more effective use of yourexisting capacity and capital investments.

Provisioning and Management: Matrix Operating Environment

Provisioning and management for HP Converged Infrastructure is delivered through softwarecomponents of the HP Matrix Operating Environment (MOE). This enables management andautomation of HP Converged Infrastructure to accelerate infrastructure delivery in a consistentlyrepeatable way. This approach ensures efficient use of IT resources and staff time, and mitigates risks.In one example of HP Converged Infrastructure deployment, MOE is delivered as an integral part ofHP BladeSystem Matrix via Insight Dynamics software, a keystone of HPs broad offerings forinfrastructure management.

Challenge

Traditional data centers are built around an aging, siloed architecture, which limits the ability to buildin efficiencies and enhance service levels. In a traditional data center deployment, it can take weeksor months to implement new infrastructure and bring new services online. This challenge can beaddressed using a shared services approach.

Shared services best practices

Automate application deployment and provisioning with standardized templates. Provide governance and auditing to ensure resource accountability. Provide a variety of platform and availability choices to ensure cost-appropriate service levels. Provide hardware for deployments from a reusable and redistributable resource pool to ensure

rapid access and maximize utilization. Update operational processes to ensure maximum efficiency for operational staff. Provide consistent reporting to satisfy management oversight.HP solution

HP Matrix Operating Environment is a shared-services infrastructure management solution. HP MatrixOperating Environment delivers a common management platform for provisioning and adaptinginfrastructure to instantly respond to business demands. The HP approach optimizes and automatesthe management of the resource pools and the IT roles associated with provisioning and consumingresources from these pools, while operating in compliance with core business, security, andregulatory policies. HP Insight Dynamics and complementary products provide the core functionality

of the Matrix Operating Environment.

Functional elements are listed below.

HP Insight Dynamics enables administrators to manage standalone physical servers, virtual machinehosts and guests, and physical hardware partitions on Integrity servers, all from a singlemanagement console. Insight Dynamics also enables both physical blade servers and virtualmachines to be managed as logical servers so they can be easily moved and migrated within aMatrix environment. It delivers a full range of deployment, management, capacity planning,migration, movement, and disaster recovery capabilities when paired with supported HP server andstorage technologies.

HP Insight Dynamics includes an embedded workflow automation engine based on HP OperationsOrchestration that provides role-based design and provisioning. This enables integration withcustomer IT processes and extensible automation based on customer workflows.

The Designer within Insight Dynamics enables drag and drop development of infrastructuretemplates for all of the components of an application infrastructure. These templates are saved toform a service catalog.

The self-service portal within Insight Dynamics provides authorized users with a catalog of availableapplications for deployment. Authorization process is driven by the embedded workflow engine.

Virtual Connect Enterprise Manager takes input from templates to provision the connectionsbetween servers, storage, and networking resources for an application.

In addition to delivering applications and services, IT is responsible for managing and allocatingcosts. A shared services model where IT resources are centralized and shared among business unitsrequires a cultural shift. Agreements need to be put in place between IT and the lines of business forthe services that the business needs to have provisioned. HP Converged Infrastructure provides usageand service level reporting tools to ensure IT can demonstrate value add to business customers as wellas track resource usage for charge-back.

Support for Industry Standards

HP has a tightly coupled partnering strategy to deliver a Converged Infrastructure in a deploymentscenario that works for your unique needs and built on industry standard hardware and interconnectsHP has more than 180,000 channel partners worldwide, including major and emerging software andhardware vendors as well as system integrators who leverage our products and services. HP worksclosely with these partners to deliver integrated solutions based on open standards. We deliversolutions that work with your existing infrastructure and provide investment protection for the future.

The HP focus on standards and open partnerships enables IT organizations to move to HP ConvergedInfrastructure at their own pace and without the fear of being locked in. It enables them to leverageexisting investments while reaping the benefits of pooled resources and orchestrated deployments.HPs Converged Infrastructure provides the advantages that come with vendor consolidation andintegrated engineering while still enabling choice and access to new technologies.

Applying the HP Converged Infrastructure Maturity Model

The technology integration described earlier in this section opens the door to major improvements indata center planning, deployment and operational processes. Infrastructure convergence reflectstodays data center economics, where hardware costs are no longer the only pivot point for ITdecisions. Other factors, such as provisioning, power and cooling, and operational flexibility nowplay an important part in platform decisions. To address those new requirements, HP has created theConverged Infrastructure Maturity Model (CI MM) to help organizations put in place the skills andprocesses required to reap the benefits of HP Converged Infrastructure. HP provides a roadmap forConverged Infrastructure and a path to make steps from your current state to an automated andadaptively sourced infrastructure.

The value of applying CI MM comes from building capability in key aspects of the data centercompetence, as shown in the following table. By adopting HP CI MM and integrating therecommended skills and tools, each area of competence can be supported by the required level ofmaturity.

Within this guide, the discussion is limited to how CI MM can assist with the rollout of applicationsservices within the HP Converged Infrastructure Reference Architecture. Specific applicationworkloads, based on the Converged Infrastructure Reference Architecture, are defined in the nextsection. For a broader view of how to apply CI MM to improve data center capability, refer to thesection at the end of this document titled For More Information.

Overview of the Converged Infrastructure Maturity Model

CI MM provides criteria-based measures of organizational capability. These criteria are based onworking with hundreds of organizations across a wide range of industries. HPs goal is to assist

companies to improve capability and achieve specific business objectives. HP has found that as ITorganizations develop maturity relative to the model, their capability to deploy shared servicesinfrastructure increases. This increased competency then generates significant value to the business.

As an example, the table illustrates how HP Converged Infrastructure aligns to the maturity model.

Skills competency and maturity levels

HP Converged Infrastructure Maturity Model matches tools and skills at each maturity level, enablingIT organizations to incrementally grow capability and see the results reflected in improved businessresults. HP Converged Infrastructure is built from standards-based products, and so enables step bystep improvement in capability. IT organizations can easily build on their existing investments, ratherthan having to start from scratch.

The following table illustrates how HP management tools enable organizations to achieve higherlevels of maturity and capability.

Operational advantages of high maturity levels

At higher levels of maturity, resource pools become an elastic extension of business requirements. Thelarge common pool of compute, storage and bandwidth means that the resources needed to meetnew requirements can be provisioned quickly. Standardization of building block resources, coupledwith simplified authorization processes mean less time and money are spent readying infrastructurefor changing business needs. At the same time, resource reporting and analysis can ensure resourceutilization, so that usage and cost allocation are transparent to business users.

Evolutionary vs. transformational approach

Adoption of converged infrastructure combines technology advances with improvements inorganizational skills and processes. Each complements the other. Within existing environments, HP

Converged Infrastructure naturally enables evolutionary adoption of tools and incremental levels ofautomation and efficiency. For new greenfield IT investments, HP Converged Infrastructure enablesIT staff to deploy resources that span business needs, rather than simply individual silos.

The next section defines recommended architectures, and some specific configuration examples, for abroad range of common enterprise workloads. Because these workloads share a commoninfrastructure, capacity planning can be much more efficient. In the past, IT grew as a set ofstandalone silos, each planned and operated separately. With HP Converged Infrastructure, thatlarger set of requirements can be addressed up front, and efficiencies can be driven across the entireIT infrastructure.

HP Converged Infrastructure Reference Architectures

Overview

HP Converged Infrastructure enables IT organizations to deploy a standards-based, commoninfrastructure to implement new solutions, or evolve existing ones. This common ConvergedInfrastructure core can be flexibly deployed to meet business objectives and create an agile ITsolution environment.

The sections that follow provide specific examples of how HP Converged Infrastructure can be used asa core architectural approach to supporting these common enterprise workloads:

ERP/CRM, using SAP ERP 6.0. Messaging and Collaboration, using Microsoft Exchange. Cloud computing, with a focus on enterprise private cloud.Virtualization, covering x86 and HP-UX virtualization technologies and three use cases.

Additional use cases are under development.

These configurations demonstrate the flexibility of the basic HP Converged Infrastructure architecture.They are a guide for planners and architects to illustrate practical application of the architecture tomainstream enterprise workloads. They also illustrate how specific tools, such as orchestrationtemplates, can be employed to simplify deployment. Please consult your HP sales representative forsupport on planning any particular solution or deployment for your organization.

Generalized Reference Architecture

HP Converged Infrastructure relies on a common set of components, associated with a comprehensiveset of service definition, deployment, and management tools. Infrastructure components can bedeployed, and redeployed, to meet business needs. These common components can be utilized all, orin part, to create a platform on which to build IT solutions. These components provide a core forsolution deployments and enhance the maturity and agility level of the entire IT environment, as

described earlier.The agile data center provisions from pools of resources for services requested by the users fromportals, APIs, or other interfaces. These virtual/physical resource pools include servers, storage, andnetworking which are allocated from automation resources over the converged network. These poolsof resources will be orchestrated by the operations orchestration to deliver the services requested viaservice catalogs based on business SLAs. Depending on the SLA, the required scalability,availability, and local or remote disaster recovery will be enabled. Monitoring of these resources willoccur at the infrastructure, application, and end user side. Capacity will be typically available on-demand and elastic to address workload spikes, such as during peak business events.

From a functional perspective, Figure 6 depicts how these data center operations are addressed bythe core elements that form the HP Converged Infrastructure architecture.

To facilitate the creation of Converged Infrastructure across typical deployment solutions, an intelligentsoftware layer Matrix Operating Environment draws from resource pools of server/storage/networkInfrastructure and pre-defined shared-service application catalogs to dynamically link the rightresources when provisioning application instantiations.

Virtual Resource Pools Servers: Pools of Servers (typically in Blade enclosures such as the HP BladeSystem with x86 blades

or HP Integrity) are maintained with HP Virtual Connect providing an IO abstraction for connectivityto networking and storage.

Storage: Disparate heterogeneous storage resources based on HP or other 3rd party disk arraysmay be combined into seamless scalable pools of storage through the use of storage virtualizationtechnologies from HP. Flexible storage access mechanisms may be used to connect to the storageincluding traditional Fibre Channel, iSCSI, Fibre Channel over Ethernet, and Serial Attached SCSI(SAS).

Network: A traditional hierarchical data center network built on heterogeneous network switchesand routers are used to connect the application instantiations within the infrastructure resource pools

to the WAN backbone. Technologies such as HP Networking IRF provide the ability for networkbackbone resources and capacity to be dynamically scaled through the grouping of switchestogether.

FlexFabric

The HP BladeSystem Virtual Connect FlexFabric module can dynamically allocate I/O bandwidth forstorage and network connections. This provides a virtualized, efficiently utilized, and highly scalabledata center fabric. This open architecture uses industry standards to provide high performance,secure, converged connectivity to storage and server resources. FlexFabric combines intelligence at


24/71

24

the server edge with an advanced orchestration and management layer to enable virtualization-awarenetworking, predictable performance, and rapid, secure, business-driven provisioning. This approachaddresses traditional network performance bottlenecks such as latency and network contention.

Matrix Operating Environment

The key software building block of the Matrix Operating Environment is HP Insight Dynamics. InsightDynamics delivers three key capabilities:

Provisioning: HP Insight Dynamics infrastructure orchestration capabilities can provisioninfrastructure in minutes to automatically activate physical and virtual servers, storage, andnetworking from pools of shared resources. Whether for a single virtual machine or infrastructurefor a complex three-tier application, Insight Dynamics finds available resources, streamlines theapproval process, and automatically provisions and configures whats needed across infrastructurepools. It also provides the ability to create a shared service catalog of application templates and aportal to instantiate individual applications based on these templates.

Optimization: Insight Dynamics captures key data points about actual system utilization likepower draw, CPU and network utilization every five minutes. This lets you quickly adjust andoptimize your environment over its lifecycle so you can predictably make changes without time-consuming analysis. When combined with built-in re-balancing tools, this can eliminate weeks or

months of tedious planning and implementation. Protection: Insight Dynamics protects quality of service and offers continuity of services with a

wide spectrum of high availability and recovery solutions, ranging from server-aware andapplication-aware availability solutions, to disaster recovery solutions for distances from campus tocontinental for both physical and virtual server environments.

Insight Dynamics builds on the essential server management delivered by HP Insight Control thatunlocks the management capabilities built into HP ProLiant servers. Insight Control enables you toproactively manage server health - whether physical or virtual, deploy servers quickly, optimize powerconsumption, and control servers from anywhere. It also leverages HP Virtual Connect EnterpriseManager (VCEM), which centralizes connection management and workload mobility for HPBladeSystem servers that use Virtual Connect to access LANs, SANs and converged network

infrastructures.

For Integrity servers, Insight Dynamics VSE also includes advanced workload management that canautomatically grow and shrink virtual servers as business needs change.

The Matrix Operating Environment is integrated with HP Business Technology Optimization (BTO)software, including HP Server Automation software for provisioning applications. By using the MatrixOperating Environment together with HP Server Automation, both infrastructure and applications canbe provisioned in minutes.

A full HP Converged Infrastructure deployment can take advantage of all of these functional areas,whether for a single application, or across an enterprise. A more limited use of the various elementsof the Converged Infrastructure functional core can still enhance IT capabilities for new or existing

applications.From the functional description above, a deployment approach is derived and shown in Figure 7below. This deployment architecture maps the Converged Infrastructure functional components to howthey can be leveraged to build actual solution architectures. This core architecture can serve as afoundation for custom application deployments, whether new specific workloads such as thosedescribed further below, brand new applications, or modifications of existing ones.

The above core HP Converged Infrastructure core reference architecture RA provides the next leveldesign. Specific reference configurations, described later, can be deployed as single or replicateddeployments, based on an organizations capabilities relative to the Converged Infrastructure Maturity

Model. Maximum benefits accrue when deployed as service-oriented architecture, leveragingmanagement automation via the HP BladeSystem Matrix Operating Environment (MOE) or HPSoftware to optimize TCO and CAPEX/OPEX.

Secondly, HP BladeSystem can be used to collapse the network layer in the Converged Infrastructure,reducing or eliminating the need to use extra hub routing to utilize the top of the rack switches,flattening the layer 2 levels. This is key to addressing virtualization: fewer hops, fewer cables orswitch NIC-SAN ports as well as performance, power, and cooling.

Lastly, the core Converged Infrastructure reference architecture can connect to an existingheterogeneous environment and in-house or 3rd party automation software to take advantage of thevirtual/physical pools of resources. These can include rack mount servers, hypervisors, Fibre Channel,iSCSI, FCoE, NAS Storage, and network devices.

This architecture is interchangeable between HP Converged Infrastructure components andheterogeneous components. The HP open, non-proprietary approach reduces costs and improvesflexibility for customers as they upgrade their environments.

ERP/CRM: SAP Business Suite 7, ERP 6.0 Use Case

Solution Architectural Principles

Basic solution description and business need

SAP Business Suite 7 is the newest application suite from SAP to help companies to optimizeperformance and reduce IT cost by synchronizing the release schedule of major SAP components(SAP ERP powered by NetWeaver, CRM, PLM, SCM, and SRM, plus industry solutions and

enhancement packages). The main benefits of the SAP Business Suite are to drive wider adoption ofService Oriented Architecture (SOA) design concepts, support for collaborative business processes,reduce the barriers for implementing new capabilities and functionalities, and provide a framework todeliver value more quickly. One of the popular components of SAP Business Suite is SAP ERP 6.0,which is shown in the figure below. The main benefits of this approach are the simplified workflowand seamless integration of the various business processes within an enterprise.

SAP ERP is powered by SAP NetWeaver an innovative integration and application platform. SAPNetWeaver lays the foundation for new cross-functional business processes.

Basic SAP architectural principle and considerations

A typical SAP architecture consists of an application stack, central services, processes and a databaseinstance. In the simplest form, all reside within a single operating environment, as shown below. Inthis case, if the application and database tier are run on a single Operating System, this is called anSAP two-tier architecture, or central-system architecture. The HP Converged Infrastructure model can

bring benefits to such SAP central system architectures by easing deployments and offering additionalresiliency features through server, storage, and network virtualization.

Sizing and scaling principles

The recommendation of the reference environment includes assumptions made by HP.

Assumptions

The SAP sizing methodology for HP platforms is based on performance data gathered from existingcustomers, tests performed in HP labs, customer tests in HP benchmark centers, and published industrybenchmarks. Input is also taken from SAP Consulting and data utilized from sizing studies of actualcustomers in production.

The SAP sizing methodology assumes that the servers, mass storage units, databases, and reportingqueries are well-tuned for the applications. A tuning effort is generally recommended before and afterthe system goes into production.

Verifying system performance with stress tests or operational performance tests is highlyrecommended in the months prior to going live with SAPand after the system goes into production.Operational monitoring of infrastructure, as well as scheduled application reports such as SAPEarlyWatch, can provide feedback on consumption patterns and overall scaling of the SAP system.

While typical SAP system monitoring focuses primarily on compute resources, a convergedinfrastructure allows for more holistic application assessments and is inclusive of network and storageI/O.

Overall resource consumption in SAP OLTP environments is concentrated within the application tier.The diagram above illustrates load distribution between application tier, central services anddatabase tier. From a system-scaling perspective, 70% of the resources are usually consumed by the

application tier and about 20-30% by the database tier.This understanding of scaling characteristics within the core SAP architecture is a key pre-requisite,when applying converged infrastructure principles. HP Converged Infrastructure provides a pool ofcompute resources and can adapt dynamically to the changes in workload by redeploying existing oradditional compute resources in the SAP infrastructure.

While growth of an SAP two-tier system, or central system architecture, is accommodated throughvertical scaling of services, an SAP three-tier system, or distributed system architecture, can allow forhorizontal scaling. In the diagram above, both SAP application tier and database tier can scale up orout (with Oracle RAC), while SAP Central Services are limited to scaling up.

A converged infrastructure provides the broader application/service view while managing thediffering scaling attributes of an SAP system. Since HP Converged Infrastructure is not limited tospecific products, it is able to allocate the right-sized resources to specific tiers within SAP.

High Availability Principles and Capabilities

An SAP system consists of components that are either single or multi-instance capable. SAP workprocesses such as Dialog, Batch, Update, etc. can be installed redundantly across multiple operatingenvironments. The database is typically single instance, although distributed databases such asOracle RAC are supported.

SAP central services, which include the Enqueue and Message processes, are Single Points of Failure(SPOF) if these services fail, the SAP application comes to a halt. SAP application servers are not


31/71

31

SPOF since availability is provided through distributed redundancy: SAP application servers can bedeployed on many servers, if one fails there are potentially other instances to cover SAP user requests

The database instance is also a SPOF, since it is a central component where SAP applications store,access, and modify data. These SPOF components are provided high availability through clustering osimilar relocation of instance services. Whether provided through redundancy or relocation ofprocesses, a converged infrastructure increases resiliency through SAP instance orchestration and bysupporting native or virtualized HA solutions without compromising the SLA to the end-user.

An example of a typical highly available SAP system is shown below.

Solution Block Architectures

Architectural Principles

The HP tiered solutions program was designed to provide broad applicability across a wide range ofcustomers and hardware infrastructure platforms (server, storage and network). However, this serviceclassification framework can be applied within a single organization to meet a variety ofdepartmental and geographical requirements. The service tiers definitions are based on RecoveryTime Objectives (RTO) and Recovery Point Objectives (RPO), and have been drawn upon HPsexperience working with several small, medium and large customers including its own internal ITimplementation.

The Shared Database Utility (SDBU) is a framework for provisioning dedicated and isolated databaseenvironments on a hosted platform. Shared Application Services Utility (SASU) is a framework forhosting multiple application resources from many different business units on a shared pool of serverresources. These concepts originated at HPs internal IT transformation projects and have been widelyused at several customer sites. This reference architecture, referred to as Shared ERP Service Utility(SESU), has been built based on the concepts of Shared Database Utility (SDBU) and Shared

Application Services Utility (SASU) applied against the Converged Infrastructure principles.


32/71

32

With the HP BladeSystem Matrix, you can take this service level concept a step further and actuallycreate and publish service templates that clearly define the various SAP services that can be deployedin your organization.

Specific configurations

This document will use two different standards of defining services based on the recovery of failuresas defined below:

Incident Recovery is the small-scale failure that does not activate the migration of the primary site

production activity to the Secondary site. Incidents are considered to have a higher probability ofoccurrence, and the ERP service line offers higher levels of service to offset the higher probability offailure. This standard is summarized in the following table:

Table 7. Service Definition Criteria for an SAP SystemINCIDENT RECOVERY CLASS RTO RPO

BASIC RTO < 24 Hours RPO = 24 Hours

ENHANCED RTO = 8 Hours RPO < 4 Hours

PREMIUM RTO = 2 Hours RPO


33/71

33

Shared ERP Hosting

Shared ERP hosting allows multiple applications to coexist on a common server platform, whichgenerally results in more effective utilization of Converged Infrastructure. The ERP Service Line offersshared service on all three standard Service Classes. This allows the Service Catalogue offering toprovide a higher level of service at a lower average cost relative to standalone server solutions.

Software Versions and Hosting platforms

The consolidation of versions, with the support commitment from the vendors, provides a decreaseddiversity in the support infrastructure and allows a higher availability at a lower overall cost. The ERPService Line must be in conversation with SAP, HP, Oracle, and Microsoft to discover methodologiesof standardizing services for existing and future applications. Other services may be provisioned ifthere is sufficient demand. The platform should provide a stable operating platform for futuredevelopment and deployment of systems. By reducing the variation and standardizing on a singleplatform, the procurement and support costs are much lower than in a distributed system.

SAN Infrastructure Required & Optional Services

All ERP service offerings may use standard storage as offered in the service catalogue. Only Specialtyservice has the option of not using standard storage. The following table provides a summary of thestandard offering in the Service Catalog.

Table 8. High availability SAP systemTier 1 Replicated RAID-1

Tier 2 Replicated RAID-5

Tier 3 Local Non-Replicated RAID-1

Tier 4 Local Non-Replicated RAID 5

Replication is provided within the service at the quoted prices for storage. Replication may beSynchronous or Asynchronous based on the offering from the approved Data center. Replicated

service to the DR site supports only the following set of combinations:

Production Tier 1 to DR Tier 1 Production Tier 2 to DR Tier 2 No other combinations are supportedBackup & Recovery Service

Backup & Recovery Service has three major component offerings to the client:

IP tape-based backup and recovery. This service is required for all classes of service and is billed tothe customer based on the number of gigabytes stored. It is the slowest and least expensive.

Snapshot or Business Continuity Volume (BCV) recovery. This is the fastest and most expensiveservice offering and is available only on Tier 1 & 3 storage.

Nearline Storage. This service splits the gap between Tape and BCV for both cost andperformance. Nearline or BCV storage may be required for certain classes of service based on thevolume of data and the RTO of that service class. The decision is technical and not financial.

Typically these are in the range of 1,000 medium-weighted SD users. Modular compute is based onthe ProLiant BL460c G6. In SAP central server form, this platform achieves SD benchmarkperformance in excess of 25,000 SAPS. In native or virtualized OE, this is sufficient capacity for asmall ERP implementation.

Availability on native operating environment installations can be supported through existing clusteringtechnologies on Linux or Windows. Virtualized OE installations provide availability features throughHA feature sets (in both VMware and Hyper-V products), and require a minimum of two blades forproduction.

Two additional blades provide compute capabilities for quality assurance and development, andtesting can be supported in either native or virtual operating environments.

Storage resources are served by a StorageWorks P4000 G2 SAN Solution using iSCSI connectivity.Capacity requirements can vary, however small productive ERP systems are typically well served with2TB of storage requirement. Suggesting 6-8 TB of usable capacity is sufficient space for growth, andto account for two non-productive copies. iSCSI is also a suitable SAN protocol for implementation.

Connect. Moreover, the Virtual Connect Manager manages virtual I/O connections to physicalblades, allowing for dynamic assignment of I/O resources to SAP instances.

The ProLiant BL460c G6 provides a modular approach in terms of compute resources. It can beprovisioned to support both native and virtualized operating environments through Blade matrixmanagement. Finally, the StorageWorks P4000 storage solution provides storage LUN virtualizationalong with the network converged iSCSI SAN protocol.

Medium ERP

This category is in the range of 5,000 medium-weighted SD users. Modular compute can be ProLiantBL460c G6 or Integrity BL870c i2. In cases of Linux, Windows, or HP-UX operating environments, theSAP system architecture is three-tier and OE homogeneous. With a minimum of six productive blades,a medium ERP requirement can be met with a scalable and highly available solution.

The productive SAP system distribution across a minimum of six blades is as follows:

SAP database and central services run together on one blade with a failover target representing asecond blade. Blades three through six represent an n+1 application tier where all remaining SAPapplication processes run.

Both platforms offer 40 to 50 percent additional scale-up capacity for the SAP database and centralservices. The n+1 distribution of the application tier provides 50 to 60 percent additional scale-outcapacity within the minimum of four blades.

Both platforms support high-availability features in both native and virtualized operating
