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:\)

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.”
