15K IOPs – Good for I/O-Intensive VMs
30K IOPs – Exceeds the Load of Many Databases
60K IOPs – Around 120,000 Exchange Mailboxes
100K IOPs!
VMware and EMC: Meeting Extreme Storage Needs
When do you need 100K IOPS on a single ESX Server?
200K Microsoft Exchange mailboxes
85 average four--way DBs
What does it take?Nearly 500 disks

Impact to existing processVirtualization reduces or spare CPU/IO resourcesVirtualization consolidates backup workloads
Virtualized systems have a significant amount of redundant data
90% of data in VM’s is duplicate (C:\)
Need more efficient method of backing-up in a virtualized environment������������
Integrated data-de-duplication and backup-to-disk solutionTremendous backup process improvements
90% reduction in VMDK backup storage requirements10x improvement in backup timesDe-dupe at source enables higher consolidation
Available as a Virtual ApplianceEnables Highest Consolidation Ratios!
Remote Information Protection – Disaster Recovery
Virtual Infrastructure Requires Flexibility in Data Replication Solutions
VMware Site Recovery Manager (SRM) Simplifies planning and execution of BC/DR processes
Integrates with and inherits characteristics of storage replication solutions
DR infrastructure needs to support both virtual and traditional deployment
Enable transition from physical to virtual
EMC DeliversBest-in-breed data replication solutions
Array-based
� All WAN topologies (IP, Layer 2, DWDM)
Fabric-based
� Compression and heterogeneous configurations
Host-based
� Critical in many physical to virtual scenarios
Application integrated
� Upgrade to app-consistent replication for all Tier 1 apps (Exchange, SQL Server, Oracle, SAP)

CUSTOMER CASE STUDY
So … What is EMC doing with vStorage?vStorage API for Multipathing
NMP getting better, PowerPath = quantum leap (Demo)No PPME or encryption in first releaseEMC Accepting Beta Sites now!
vStorage APIsI/O dedupe and Acceleration via offloads (Demo)Thin Provisioning IntegrationBlock-lists for accelerated svmotion, VM-object operations on LUN-managed objects
Virtual Storage AppliancesCelerra VSA freely available – iSCSI, NFS (Free!)Avamar Virtual Edition – shipping for 1 year
vStorage API for SRMEMC still only vendor with solutions for every size, topology, and sync/async/continous, homo/heterogenousDeployed in customer production environments todayFailback supported in v1.0, working to automateNFS coming in Q2 2009EMC and VMware working together to accelerate features
vStorage Backup FrameworkNetworker and Avamar are in, and are working to leapfrog in FY 2009

2007 Server Virtualization Survey Results - IDC
Chart Source: IDC’s Server Virtualization 2007 MulticlientStudy, Dec 2007. Chart shows percentage of survey responses to a question about primary brand of network storage attached to virtual servers. N=311
“For virtual servers, networked storage solutions are more heavily weighted toward EMC storage. In previous years, storage attached to virtual servers was highly captive relative to the server hardware purchase.”
