VMware Delivers Innovative Technologies

• ESX Server 3 and VirtualCenter 2 – powerful virtualization platform• 4+ years of data center experience• Proven reliability, performance and scalability

• Platform for transformative services from VMware and our partners• Virtualization lets you do things not possible with physical systems

• First service was VMotion• New with this release: Distributed availability services,

Distributed resource scheduling, Consolidated backup

Making virtual machines better than physical machines


Virtualization Everywhere!

• More x86 servers and storage hardware supported• Expanded virtual machine capacity and management

scalability• Simplified management• Meets demanding enterprise datacenter requirements• Expands footprint of virtualization from branch offices to

biggest data centers


ESX Server 3 New Features Virtualization Everywhere!

• NAS and iSCSI storage• Expanded hardware compatibility list• 4-way Virtual SMP• 16GB guest memory• Hot-add virtual disks• Red Hat Enterprise Linux 4 guests• Multiple snapshots• Enhanced performance• Updated Service Console (Red Hat

Enterprise Linux 3)• More flexible networking• 64-bit guest technology preview

Lower Cost Access to the Benefits of Virtual Infrastructure

• NAS• NFS client built into ESX Server• NAS can be used in place of VMFS as the file system for virtual disks

• iSCSI• Use hardware iSCSI card or built-in software iSCSI• ESX Server boot from iSCSI (for hardware iSCSI only)

• Both• VMotion, distributed resource scheduling, and distributed availability services

all extend to non-fibre channel shared storage• Storage option transparent to guests

ESX Server 3 New Features NAS & iSCSI Details


• Single Windows and browser client for ESX Server and VirtualCenter

• ESX Server configuration through VirtualCenter

VirtualCenter 2 New Features Simplified Management

• Remote devices• Topology maps• Centralized licensing• All VM files (vmx, nvram…) on

VMFS


• Custom roles and permissions • VirtualCenter audit trails• Increased scalability

• Hundreds of VMware servers• Thousands of virtual machines

• Faster startup, more responsive• VirtualCenter session management• Enhanced performance graphs• Enhanced SDK

VirtualCenter 2 New Features Enterprise-Ready


Major New Technologies

• Clusters• Distributed resource scheduling• Distributed availability services

• Resource Pools• VMware consolidated backup


ClustersThe Power of Many Hosts, the Simplicity of One• Reduce management complexity by combining stand-

alone hosts into clusters for higher availability and more flexible resource controls

CPU = aMem = x

CPU = bMem = y

CPU = cMem = z

Stand-alone hosts Cluster

Pooled ResourcesCPU = a+b+cMem = x+y+z

AvailabilityTransparent

failover


Distributed Resource Scheduling Add-OnCreating a Unified Compute Resource• Global scheduler

• Automates initial virtual machine placement• Uses VMotion to continuously optimize based on current workload• Reacts to adding or removing hosts from the cluster

• Achieve >80% utilization

Distributed Availability Services Add-On

High availability for all your servers• Losing a host in a cluster means fewer resources, not lost

virtual machines• Impacted virtual machines are restarted on remaining hosts• Placement optimized by global scheduler• VirtualCenter handles all setup and configuration automatically

• None of the cost and complexity of clustering

Shared Status


Resource Pools

Virtual Machine Containers with Assigned Resources• With resource pools you can…

• Let a user create and run as many virtual machines as desired while limiting the total resources used

• Instantly add extra resources to an enterprise application• Delegate control over assigning resources to virtual machines while

maintaining complete control over hardware

Resource Pool(CPU= 8 GHz, Mem = 6 GB)

VM VM VM VM


Resource Pools

Precise Resource Control• Virtual machines draw resources from their resource

pools• Resource allocations can be changed dynamically• Resource pools can be nested

Cluster capacity:5 x (4.8 GHz, 4 GB)= (24 GHz, 20 GB)

Floating capacity:5 GHz, 5 GB

Resource Pool 1(CPU = 16 GHz, Mem = 12 GB)

Resource Pool 2(3 GHz, 3 GB)

VMware Consolidated Backup

Centralized File-Level Backups with No Agents• Move backup out of the virtual machine and into the

infrastructure layer• Manage centralized

backup service instead of agents

• File system-consistent live snapshots

• Remove backup load from ESX Server hosts and virtual machines

• Pre-integrated with major third-party backup products


Architecture Highlights

• Simplified Service Console• VMFS3• Virtual Infrastructure Object Model• Virtual Infrastructure Architecture


Simplified Service Console

• Service console I/O more like a virtual machine• Virtual I/O devices for the service console• All storage and network devices dedicated to the vmkernel• Easier install: no more dividing physical devices between virtual

machines and the service console

• Service console resource needs independent of the number of virtual machines• vmx processes moved from

service console to vmkernel• Service console not a bottleneck

to scalability• More accurate virtual machine

resource accounting


VMFS3• Revamped disk locking

• Better scaling for access by large numbers of hosts simultaneously • Enables large clusters for distributed resource scheduling and distributed

availability services

• Greater reliability and flexibility• Distributed journaling for faster recovery• Logical volume manager

• Resize LUNs, add LUNs on the fly• Volume availability not compromised due to spanning

• Store more than virtual disks• Exclusive repository for virtual machines and VM state

• Virtual disks, configuration files, snapshots

• Directories to organize files• Optimized for large and small files• Optimized for a large number of files

• Virtual disk performance remains close to native


API

Virtual Infrastructure Object Model

• Full object model for virtual infrastructure forms the foundation for VirtualCenter 2

• Internal API = public API• Same API exposed at VirtualCenter and ESX Server• API available at both VirtualCenter and at ESX Server

hosts

VirtualCenter


Virtual Infrastructure Architecture• Host agent exports virtual infrastructure API on ESX Server 3• VirtualCenter Agent supports new or legacy hosts• Optimized VirtualCenter-to-host communication

• Core data cached in VirtualCenter database with event-driven updates• VirtualCenter gets increased scalability, faster restart and becomes more

responsive
