Comparing the Power Utilization of Native and Virtual Exchange Environments

Nathan Winters just tweeted about a whitepaper on the Microsoft site.  It compares physical with virtual Exchange implementations. 

“Reducing or controlling the high cost of the power to run and cool computer hardware is a top priority for many organizations throughout the world. Many organizations are considering server virtualization solutions to reduce their server footprint and the associated power and cooling costs. Because the virtualization of Microsoft Exchange servers rarely results in a reduction of physical processors, there is some question whether there is significant hardware, power, cooling, or space savings from virtualizing correctly sized Exchange Server 2007 server roles. This study compared the power utilization of native and virtual Exchange server environments in a scenario in which the number of physical servers was reduced from eight to two, but the total number of logical processors and the amount of memory remained the same.

When you consider virtualization of an Exchange environment, power savings is only one of many factors to consider. Depending on your requirements, virtualization may not be a good fit for your Exchange environment.
