VMware touts the impact of server virtualization on green IT. …

… “VMware virtual infrastructure helps enterprises and governments reduce their energy costs and consumption by as much as 80 percent. Most desktops and servers today are in use only eight to 15 percent of the time they are turned on, yet they consume 60 to 90 percent of the normal workload power even when idle. VMware vSphere has advanced resource and memory management features that will enable consolidation ratios of 15:1 or more and dynamically power off unneeded servers, which increase hardware utilization to as much as 85 percent.

Every server retired from a datacenter saves an estimated four tons of CO2 emissions, equivalent to taking 1.5 cars off the road or planting 55 trees. Similar opportunities for savings are available for desktop PCs, which can be consolidated on servers in the datacenter using VMware View. VMware vSphere 4 is expected to be generally available during the second quarter of 2009. ” …
