Microsoft Corp. today announced that some business customers around the world have saved on average $470,000 (U.S.) per year through IT projects using Microsoft virtualization software. Microsoft’s business customers have been able to use virtualization to help reduce operations and capital expenses via reduced electrical power consumption and cooling within datacenters, reduced hardware acquisition costs, automation of desktop and server management, and centralized application deployment.
The cost of running IT systems has increased as electrical power, cooling and physical space has become constrained. In his 2008 refereed journal article, “Worldwide electricity used in data centers,” Jonathan Koomey, Ph.D., of Lawrence Berkeley National Laboratory and Stanford University concluded that total datacenter power was about 1.5 percent of all U.S. electricity use in 2005, with 80 percent of that amount going toward powering and cooling servers. A separate report, by Gartner Inc., stated that “the effective use of virtualization can reduce server energy consumption by up to 82 percent and floor space by 85 percent” (Gartner: “Energy Savings via Virtualization: Green IT on a Budget”; Nov. 12, 2008)...................Continue At Source
