Census consolidation by the numbers

The U.S. Bureau of Census is virtualizing servers and storage as it moves toward a virtual private cloud. Here are the key data points of the project:
Windows servers: 52 percent virtualized, a little more than 700 servers.
Linux servers: 5 percent virtualized, ahead of pace to have 8 percent virtualized by end of fiscal 2011.
Virtual machine guest-to-host server ratio: 5 to 1. Census expects to double that ratio as it decommissions more legacy servers.
Storage: Consolidating 52 arrays to seven; reducing seven storage vendors to two.
Impact: Census' primary data center has experienced a 10 percent drop in power consumption over the last six months. This initial stage of its virtualization project saved $2.5 million.
