One technology that can help companies increase efficiency is virtualisation, which can play multiple roles in the datacentre.
Virtualisation makes it possible, for example, to divide a single server into smaller virtual servers, or pool smaller, individual machines so they can perform as one larger system. Gartner estimates that more than 90 percent of companies using virtualisation are doing so to reduce x86 server space and costs. In fact, the company estimates that virtualisation cut the x86 server market by four percent in 2006.
Power savings can be even greater when addressing storage assets. Storage resources - which IDC says are growing 50 percent per year - are among the largest consumers of energy in the datacentre, in most cases consuming 13 times more power than processors. What's more, use of storage assets is often 25 percent or less, making this environment almost as inefficient as x86 servers.
I have been saying this for quite a while, so lets get started!
