Vir t ual izat ion Means Server Vi r tu a l izat ion?

Forrester Research, Feb 7 2007, 10

Server virtualization has quickly surpassed other forms of infrastructurevirtualization, including techniques for virtualizing storage and networks.

Globally, 75% of 1,221 enterprises surveyed by Forrester say they are aware ofserver virtualization technologies, 26% have implemented it, and 8% more willpilot it by the summer of 2007. The rapid adoption of server virtualization can beattributed to its near- and longterm advantages, which allow firms to reduce costswhile making their infrastructures more flexible over time. Unlike compute grid

technologies, which require architectural changes, server virtualization allowsfirms to easily encapsulate existing applications into containers that can bemoved between physical servers. Forrester believes that this basic capability willprime firms data centers for more advanced Organic IT technologies, includingautomated configuration and distributed workload management.

Reduced hardware and operationalcosts with increased utilization on

fewer servers

Created a highly flexible landscape thateasily adjusts to performance needsand changing business requirements

Simplified SAP data centermanagement by reducing complexity

MARS Incorporated partnered with SAP to implement anAdaptive Computing Controller, a capability of SAPNetWeaver that uses virtualization technology todramatically simplify the management of the SAPlandscape.

The Adaptive ComputingController from SAP was the key

driver to significantly reducing theoperational costs and dramaticallyincreasing the flexibility of our ITinfrastructure.
