Executive overview

Today’s enterprise CEOs recognize that business analytics are critical to the success of many functions, such as marketing, product pricing, demand prediction, supply chain optimization, and customer relationship management. Incorporating analytics into your business can increase revenues, improve processes, reduce costs, and help you to more effectively target customers. Insightful analytics changes how everyday, fundamental business decisions are made.

Savvy strategists recognize that combining data from across their platforms might well hold the key to making better informed decisions. Further, they recognize that SAS is the software that can effectively drive the transformation of their enterprise, from the fundamentals up through the business. With SAS, enterprises can shape big data into practical decisions that differentiate and innovate. By using SAS, you can harness data from throughout your enterprise, to integrate it, and to then act upon it as quickly as your success demands.

SAS is at home in the IBM® zEnterprise® environment and is aligned with an IBM strategy to help you fully use your network in what is, by necessity, an increasingly multiplatform IT world.

For the past 35 years, SAS has run on the mainframe, and the mainframe remains a critical platform in its long-term strategy. The IBM approach enables a hybrid platform. With this approach, you can decide the optimal combination of operating environments, such as mainframe, Windows, UNIX, and Linux, for your business. This approach also provides an environment in which SAS deployment options can more effectively and efficiently be realized, further optimizing your overall IT investment.

Many enterprises have a multiplatform environment with data and applications spread across various platforms. Many enterprises rely on zEnterprise systems to host their core applications and data. But, to take full advantage of a myriad of applications and to satisfy specific organization or department needs, other platforms, such as UNIX, Windows, and Linux, are integrated into the network.

The IBM zEnterprise BladeCenter® Extension (zBX) is a key component of the zEnterprise System offering, providing end-to-end management with the IBM zEnterprise Unified Resource Manager. Unified Resource Manager provides system provisioning, energy monitoring and management, goal-oriented policy management for applications, increased security, virtual networking, and virtual machine storage management in a single interface.

The hybrid architecture of the zEnterprise System environment matches well with SAS deployment options. In turn, these options open an array of software deployment options for

the mainframe-minded customer. This architecture provides the best combination of compute power, security, and service-level assurance. With this architecture, you can choose the most effective and cost efficient way to run SAS application components.

In a traditional environment, getting at the distributed data also requires substantial new expertise and investment in physical network infrastructure. Deploying SAS on the zBX, with its virtualized servers and networking, eases some of that burden.

The case for retaining and using your current mainframe environment to continue to deliver valued business outcomes is sound. SAS offers proven solutions to fully realize its potential. International banks are using SAS on the mainframe to monitor fraud. The financial services, manufacturing, and insurance industries, among other industries, employ it to streamline processes.

This IBM Redguide™ publication illustrates how, by deploying SAS in the zEnterprise environment, you can fully use data that is spread across your enterprise to make better informed business decisions. It addresses how IBM z/OS® customers can take full advantage of SAS in an enterprise environment. The target audience for this guide is executives, data center managers, and IT managers.

Today’s enterprise strategies and the mainframe

Strategic IT support for the enterprise today involves balancing several sometimes conflicting objectives such as the following examples:

� Facilitating an agile environment that supports new initiatives� Improving efficiency� Meeting security demands� Realizing a rapid return on investment (ROI) in both hardware and software� Gaining more profits for less investment

In the past, enterprises had the mainframe as one of multiple platforms deployed in their environments. Each platform required staff with unique skills. To curtail costs, enterprises tried to converge skills and promote improved collaboration.

Now enterprises also mandate centralizing assets, unifying expertise, and deploying a more cost-effective architecture. This architecture is one that provides an effective and efficient home for the applications that will boost the competitive advantage of your enterprise.

New computing demands

The mainframe remains the repository for most corporate data and runs most operational business applications. The mainframe is effective for operational business applications and traditional analytics processing. However, sometimes these new application requirements are more effectively implemented, from architectural and cost/performance perspectives, on other platforms, such as IBM AIX®, Linux, or Windows. IT might also need to accommodate new servers and software and provide on-demand analytics to a desktop, tablet, or smartphone. The IT environment might be required to provide statistical analysis and reporting.

As more enterprises incorporate advanced and real-time analytics into their decision making, analytics processing environment needs now include solutions such as the following examples:

� In memory databases� High performance analytics

2 Taking Advantage of SAS in an IBM zEnterprise Multiplatform Environment

� Server-based applications� Grid computing and mid-tier web-based applications� Rapid, sophisticated scoring of transactions for operational systems� Fast retrieval, search, and analysis of big data

To deal with changing requirements, enterprises deploy components that require a large memory, numerous computational cores, and highly graphical presentations that require a particular system.

Complex deployments

Businesses often need a hybrid application implementation that consists of components that are on the mainframe and other platforms. This diverse architectural environment can create several issues, such as the following examples, that must be addressed:

� A complex networking infrastructure� Decentralized management and operations� Absence of end-to-end service-level and performance management� Fragmented support, operations, and maintenance processes� Nonintegrated resource allocation and deployment processes� Hybrid environments

These demands are considerable and dynamic. Likely, today’s enterprise mainframe strategy fits into a hybrid architecture environment that embraces cloud computing. Cloud computing provides ubiquitous network access, high scalability, and location-independent resource pooling. It breaks down boundaries, facilitates more rapid delivery of new services, and allows organizations to do more for less.

Many organizations make decisions based on sensitive or personal data. They are also confronted with regulatory compliance requirements that deal with its use and availability. It is vital to keep such data in a secure environment. The mainframe has been, and remains, the natural home for secure data.

How SAS can help drive enterprise strategies

Enterprises need the capacity to gather their information and to build a network that can adapt and grow, in addition to meeting new challenges as they arise. Data must be accessible across the enterprise, from any platform. The analytics environment must be comprehensive, integrated, built for the future, and easy to maintain and manage.

SAS provides a comprehensive, fully integrated business analytics framework that addresses users’ evolving needs across the enterprise. This framework makes it easier to share consistent, holistic views of the business and enhances decision-making abilities.

Steps in driving enterprise strategies

The first step in driving enterprise strategies is to realize that IT organizations are in a unique position to capitalize on data by managing information as a valued asset. They have the power to deliver real change by providing integrated analytic solutions to the lines of business across the organization.

The second step requires understanding that analytics are different from operational and business intelligence applications. Designing a robust, flexible analytical infrastructure is

instrumental to achieving analytic success, and this responsibility falls squarely upon IT. Analysts need a sandbox type of development environment, one with the power to quickly produce many model iterations to discover the best one.

CIOs and IT organizations can, and should, play an instrumental role in driving the radical changes that are required to manage valuable data and support the use of analytics across the enterprise. The following obstacles, among others, must be overcome:

� Integrating analytics and operational processing� Meeting the demand for faster answers � Ensuring security and compliance� Handling growing data volumes and complexity

Building an analytics architecture

IT is tasked with developing an infrastructure that can support the various requirements for analytics, including reliability, performance, and scalability. CIOs must be aware of enterprise architecture standards and specifications that can scale with growth, adhere to global standards, and meet local requirements.

An integrated, enterprise analytical frameworkThe analytics and data warehouse environment should not be designed in a silo fashion. Rather, the environment should be comprehensive, integrated, built for the future, and easy to maintain and manage.

SAS can help IT organizations develop an enterprise analytical framework. This framework encompasses data access services, appropriate data marts, and an enterprise data warehouse. It also encompasses integrated analytical disciplines so that value from cross-departmental analytic efforts can be shared, put into operation, and optimized.

High-performance analyticsIncreasing the numbers and types of models that are available for creating predictive insights can improve the quality of analytical results. High performance analytics from SAS enable analytical teams in the following ways:

� Move from using simplistic to more advanced models.� Use more granular data for analysis rather than small samples.

Models run in a fraction of the time with complete data, so that analysts can experiment more thoroughly and produce better answers in timeframes that were not previously possible.

Analytic lifecycle management To achieve analytical innovation and manage the analytics lifecycle across the organization, CIOs and IT organizations must perform the following tasks:

� Provide an effective environment for the model development process.� Involve multiple teams and analytic disciplines in managing the process.

SAS can help IT deliver the advanced analytic infrastructure and data preparation capabilities that are necessary to support an iterative, multipronged approach to creating and validating analytical models.

After the analytical models are developed, validated, and selected for production, IT must be involved in incorporating the results into operational systems. This step is key to continuously improve the business. SAS can help build production-ready processes that span

4 Taking Advantage of SAS in an IBM zEnterprise Multiplatform Environment

infrastructure support, prepare data, deploy models, and ensure that all models maintain required performance standards.

SAS can help you move beyond a limited, project-based approach to tame the entire business analytics lifecycle. SAS capabilities range from data acquisition to sandbox-style model development to production deployment and continuous feedback loops into operational data.

Deployment diversityBusiness agility requires architectural flexibility. SAS provides numerous deployment options, ranging from on-premise applications and cloud deployments to support for data warehouse appliances and mobile apps. SAS works with varying architecture topologies and an array of hardware vendors to support symmetric multiprocessor (SMP), massively parallel processing (MPP), and grid implementations, helping get the best ROI from infrastructure investments.

Business solutionsSAS provides an expanding range of horizontal solutions. These solutions address the issues that affect all organizations, such as achieving greater return on customer relationships, measuring and managing risk, and optimizing IT networks.

SAS vertical solutions use extensive domain expertise to surface information in the context of the unique business processes of each industry. Such processes include anti-money laundering in financial services, expediting drugs to market in life sciences, identifying cross-sell opportunities in retail, and producing demand driven forecasts in manufacturing.

Extending enterprise capabilities with SAS on zBX

The IBM zEnterprise BladeCenter Extension is a key component of the zEnterprise System, offering end-to-end management with the Unified Resource Manager. It provides system provisioning, energy monitoring and management, and goal-oriented policy management for applications. It also provides increased security, virtual networking, and virtual machine storage management in a single interface.

Enterprises can now more fully use their mainframe with AIX, Windows, and Linux, with the help of the IBM System z® and the zBX blade environment. The IBM System z® and the zBX blade environment includes various capabilities that support the enterprise with integrated resource management, specialty processors, and a secure high-performance private network.

An ideal platform with zBX

The zEnterprise System extends the strengths and capabilities of the mainframe (such as security, fault tolerance, efficiency, virtualization, and dynamic resource allocation) to other systems and workloads. It fundamentally changes how data centers can be managed.

Deploying SAS into this multiplatform environment helps to meet evolving objectives with advanced analytics and big data solutions. The zEnterprise System now offers the optimal environment in which to do so.

The zEnterprise System with zBX is an ideal platform for hosting multi-tier SAS applications that have data and components that are on the mainframe and on other platforms. The z196 and zBX blade extensions offer rapid upgrade options to react to ongoing resource

requirements that change over time. Figure 1 shows the flexibility, layout, and relationship of the components of a zBX environment.

Figure 1 zBX environment

In coupling a local UNIX environment to a local z/OS environment on the same hardware, the zBX brings several technologies that facilitate the SAS deployment process. Where traditional UNIX and z/OS environments might have site-specific barriers in place, the zBX environment unites them under an internal secure network.

Speed, flexibility, and security with SAS on zBX

SAS today offers that advantage within a zBX mainframe deployment. SAS has been running on the mainframe for 35 years, and its commitment to the mainframe going forward remains strong. SAS on the zBX offers integration and virtualization of networks for these purposes:

� Simplification, ease of implementation, and reliability� Centralized resource deployment and management with Unified Resource Manager� Full component redundancy and failover capabilities throughout� End-to-end performance management and service-level reporting

Some enterprises have evolved into what are known as deployment silos. In these cases, their z/OS environments and distributed environments are nearly isolated from each other. In some cases, this structure exists because they have policies against integration. However, the business has evolved since the initial deployment, and their systems must be integrated.

SAS on the zBX allows IT organizations to pull these components together:

� Creating an environment with simplified management� Reducing power requirements� Improving security

6 Taking Advantage of SAS in an IBM zEnterprise Multiplatform Environment

� Reducing floor-space requirements� Improving upgradability

With these components tightly integrated, much faster interaction occurs between the back-end pieces that are running on the mainframe and the other components that are running within the zBX. These improvements are realized in large part due to the speed of the zBX internal private network.

A primary objective of the zBX is to create an environment that integrates System z and other platforms in a fully compatible way. This capability means that software that runs on the other platforms do not require special integration code for the platform to communicate.

Operational data will remain on the mainframe for the foreseeable future, but it has to share information with the analytic components that are elsewhere. To share this information, enterprises need a highly secure and tightly integrated network. SAS on the zBX provides this service.

Test deployment of SAS on zBX

To demonstrate the potential for a zEnterprise deployment, SAS and IBM joined forces in the IBM Innovation Center in Dallas, Texas, to conduct a test deployment of SAS Enterprise BI Server. SAS Enterprise BI Server is a complete business intelligence offering. It includes portal capabilities, customizable dashboards, and advanced reporting. Traditional z/OS data is primarily accessed by batch-based processes, but SAS Enterprise BI makes that data available in real time across the entire enterprise.

Enterprise deployment architecture

In this demonstration, SAS Enterprise BI was deployed in a three-tier web-based enterprise solution (Figure 2 on page 8) with the following components:

� Server tier that provides access to SAS application data, with the SAS metadata server, running on z/OS, at its core

� AIX-based IBM WebSphere® Application Server providing the SAS application, web-reporting capabilities, and WebDAV data storage, and with IBM DB2® on AIX as the database provider

� Client tier

Figure 2 Three-tiered solution

The Unified Resource Manager, specialty processors, and a secure high-performance private network between the System z and AIX blade environments were the basis for the solution.

The Dallas deployment showed the zBX environment to be suited for customers who have back-end operational data and user data that is in AIX and System z environments. Although the team chose to deploy on AIX, the same results might be true with Linux and Windows environments by using zBx.

SAS deployment experience

A multiplatform deployment of SAS software is supported by several software applications and features, such as the SAS Software Depot, which is hosted in the UNIX environment.

Acquiring the softwareThe preferred method for acquiring SAS software is to use the SAS electronic software delivery (ESD) system to download the software over the Internet. After the software is downloaded, IT organizations can create physical media on-site, if needed.

The SAS Download Manager is the application that is used to download software from the ESD download site to create a SAS Software Depot. The SAS Download Manager is a client based on Java that, when installed, can download selected SAS products to a SAS Software Depot location.

Installing the software SAS installations are initiated from a SAS Software Depot. All of the software for the multiplatform deployment is in the SAS Software Depot, providing network access to the single repository, or depot, from all target installation machines and conserving space. The SAS Software Depot can be hosted in UNIX or AIX within the zBX blade environment and can be available by using a Network File System (NFS) read-only mount to all nodes in the deployment.

The SAS Deployment Wizard is the common interface Java application that is used to install, deploy, and maintain SAS software. The SAS Deployment Wizard is the means for interacting with the SAS Software Depot. The SAS Deployment Wizard is started from each system that is part of a SAS software deployment and provides a broad range of deployment opportunities.

Installation on the test deployment For the Dallas test, the SAS team chose to host the SAS Software Depot on AIX and make it available by using an NFS read-only mount to z/OS. This implementation was accomplished with ease. Due in part to the existence of the zBX private network, the test did not entail extensive time to implement procedures to protect unauthorized network access of the SAS Software Depot.

Benefits of deploying SAS on zBX

The SAS experience with the zBX in the IBM Innovation Center in Dallas proved that one SAS Software Depot can install all components with ease, free of network and policy restrictions, across all environments, with no modifications. Fully using the mainframe requires responding to many deployment considerations and integrating domain expertise. SAS on the zBX meets these challenges.

The benefits described in this section result from advantages in both SAS deployment software and zEnterprise hardware capabilities. They reflect continued efforts by both SAS and IBM to take full advantage of all platforms that are available to the enterprise.

Integrated platform expertise

Deploying a cohesive multiplatform, multi-architecture environment requires many layers of domain expertise. Often this expertise is controlled by different departments, making the deployment process cumbersome.

It takes much expertise to install any software in an enterprise-wide environment. Most organizations are likely to have IT specialists that support specific operating systems and

SAS metadata server: The installation of the SAS Foundation software began on the z/OS server tier through the NFS mount to the SAS Software Depot. When installed, the SAS metadata server was configured and started. The SAS metadata server is the central hub for the SAS Enterprise BI environment and must be available for the remaining server and mid-tier deployments.

9

environments. They might also have specialists for other aspects of the IT environment. In deploying SAS Enterprise BI, all those groups must be involved.

SAS on the zBX facilitates more widely disseminated knowledge, streamlining the deployment process.

UNIX System Services provides several valuable system features. z/OS requires UNIX System Services for deployment. UNIX System Services is especially important in an environment in which connectivity to Windows or UNIX systems is required. It is key to the zEnterprise design. It is also at the heart of any SAS Enterprise BI deployment that involves z/OS.

SAS is ready today to take advantage of z/OS UNIX System Services and the zEnterprise environment to develop a cohesive deployment process across the entire enterprise. With SAS on the zBX, the box contains a full fledged UNIX system. This solution is all about bringing these two technologies together, and with that, beginning to bring the domain expertise together as well.

Fewer z/OS disk space requirements

Disk space issues are another primary concern for customers. Previously, customers received tapes to load SAS. They ran batch jobs that unloaded these tapes. If they had a catastrophic failure or needed to reload SAS, they unloaded the tapes again.

However, with the SAS Software Depot-based deployment, customers need SAS Software Depot available for deployment and maintenance, using disk space. Therefore, IT environments allocated considerable disk space on an ongoing basis.

With SAS on the zBX, the SAS Software Depot does not have to be hosted on z/OS. It can be easily hosted on AIX or Linux, where disk space is likely to be less costly. Customers still have to gain access to the SAS Software Depot for deployment. However, they can now use the NFS to host the SAS Software Depot and access it remotely over the internal network as though it were still local. This approach reduces the complexity of implementing and maintaining SAS on the mainframe.

If a z/OS site does not currently use the SMS, the zBX coupled with the NFS is an attractive alternative.

Streamlined software delivery

Delivering software to the customer securely and timely can be an issue. Today, the IT industry, including SAS, is shifting to a download-based mechanism for delivering software, which is widely believed to be a positive development.

Many sites require physical media in the form of DVD. The additional network security offered by zEnterprise can enable use of DVD or encrypted downloading of software that is as secure. Use of electronic download is especially important in delivering a fix for a problem, which is cost-effective both in time and money compared to network delivery.

With SAS on the zBX, installers can host the SAS Software Depot in AIX or Linux disk space and then use the NFS to gain access for mainframe SAS software deployment.

In situations where electronic download is not a viable option, customers can still request to have the software delivered by using DVD. The SAS Software Depot can then be loaded on

10 Taking Advantage of SAS in an IBM zEnterprise Multiplatform Environment

the zBX blade environment. When loaded, NFS access by using the private network is used to deploy SAS software on z/OS.

Electronic download has the further advantage of quicker, less expensive delivery, and customers can purchase on their own timetable. Also, zBX addresses security issues related to downloading.

Improved BI installation capabilities

Users install SAS by using the SAS Deployment Wizard, which is a graphical Java program that gives the user an interactive environment. This wizard prompts the user to respond to questions and allows the user to click and drill through the deployment process. z/OS requires a graphical environment to display to the user interface.

A user can install SAS Foundation software by running the SAS Deployment Wizard, which now has a console mode available. The user can run the SAS Deployment Wizard with the dash console on the command line. The wizard does all the character-based prompting for SAS Foundation and BI customers.

Local UNIX environment included

The cost of maintaining z/OS, AIX, Linux, and Windows servers as separate pieces of hardware and keeping the versions in sync is costly. SAS on the zBX now brings them closer together. zBX makes maintaining and updating these separate operating systems less complicated and less expensive.

SAS software must be installed from an SAS Software Depot, and in an enterprise-wide environment IBM has three distinct tiers:

� Server tier, which provides access to SAS application data� Mid-tier, which provides web-based access (on either UNIX or Windows)� Client tier, which includes personal computers, such as desktop computers or notebooks

With the zEnterprise System, sites can deploy a single SAS Software Depot for all systems. This approach can be a significant savings in deployment and maintenance effort, not to mention a reduction in disk space and other expenses.

Installing zBX provides AIX, Linux, and Windows server systems with SAS Software Depot. By using the internal network in the zBX, hardware, data, and software are protected from unwanted external access. This secure environment exists because no access is possible to the outside world unless IT or the business unit chooses to provide it by using a separate network adapter.

Improved environment for the Network File System

In deploying SAS on the zBX, installers have a natural environment for the NFS, which provides for the sharing of file systems by multiple machines. NFS servers and clients are available on Linux, AIX, and z/OS. These customers might be reluctant to make their z/OS systems visible to network mounted file systems. zBX enables usage of the NFS in a safe and secure way by z/OS and virtual machines within the zBX by using the virtual private network.

Client tier: Devices in the client tier can require installation of SAS software. Ideally, a multiplatform deployment might have one SAS Software Depot with all the software necessary and have it accessible to all those computers.

11

Prepackaged Java software for installation

The SAS deployment process is based on Java. That is, customers who run SAS on z/OS must load Java and make it available on the system as a preinstallation requirement.

For customers who do not use Java in their current environments, Java is now packaged in the SAS Software Depot (for deployment purposes only). Again, with SAS on the zBX, expertise is now more integrated, because those individuals in the AIX domain know Java.

Summary

The mainframe remains a key element of any business intelligence environment and will remain so for the foreseeable future. Both SAS and IBM are committed to the mainframe as a strategic platform for the future.

SAS and IBM are aligned in their mainframe strategies. The IBM approach is to embrace a hybrid platform IT environment. This approach facilitates new options for an expanded selection of offerings for customers, by enabling them to combine operating environments and have that environment overseen by the IBM zEnterprise Unified Resource Manager. SAS can be more effectively and efficiently deployed in this environment than ever before, further taking advantage of your mainframe investment.

The zEnterprise hybrid architecture matches with SAS deployment options, offering the best combination of compute power, security, and service-level assurance.

zBX is a key component of the zEnterprise System. zBX offers the ability to implement multiplatform, multi-tier SAS applications in a centralized unified environment with the production data center qualities that mainframe customers have come to expect.

With SAS on the zBX, the deployment of application components across platforms and servers can be optimized to meet your cost and performance criteria. Within this environment, and with SAS, you can take full advantage of your mainframe investment and pursue the opportunities to use your data wherever it is to your advantage.
