2 Top IT Goals for Virtualization Top 5 IT Objectives for Virtualization Source: VMware customer survey January 2010 Use virtualization to improve business continuity 46% Improve virtual machine performance 33% Increase the server consolidation ratio 32% Improve VM environment management 31% More mission-critical applications 24% Copyright 2009 VMware, Inc.

Virtualization Makes DR Easier, More Reliable Hardware

hardware Repurpose previous generation equipment to recovery

as flat files on disk Entire systems can be protected with

hardware requirements at production and DR sites Can use

Transparently share and allocate hardware resources

3 Virtualization Makes DR Easier, More Reliable Hardware Independence Reliably recover a virtual machine to any hardware Repurpose previous generation equipment to recovery site Encapsulation All information about a system is stored as flat files on disk Entire systems can be protected with data protection tools Partitioning and Consolidation Reduced hardware requirements at production and DR sites Can use higher consolidation ratios at DR site Resource Pooling Transparently share and allocate hardware resources Automatic resource optimization Automation is needed to lower risk, increase confidence

42 SRM in the Real World Japan Disaster: Rolling Blackout Avoidance I hope that the relative success of the running of the DR plan will also open the eyes of management to more prevalent use of VMware, specifically for the disaster recovery benefits. I can say, without going into detail, other critical systems (outside of the virtual infrastructure) did not fare as well! Thanks VMware! Thanks SRM! Mission accomplished... 45
