"There are a couple of ways to measure server utilization. There are servers that sit idle waiting for useful work, and then there are servers running applications that are no longer needed or used by an organization and are considered orphaned or abandoned. The abandoned application can be moved to a virtual machine, the server decommissioned, and the space, power and cooling capacity recovered to support additional growth. CIOs should strive for an orphaned server percentage in the 1 to 2 percent range."-Mark E. Stumm, vice president of product marketing at performance management developer nlyte Software.
Single-instance server environments have embarrassingly low utilization rates. A 10 percent rate is considered nominal even under heavy workloads, which means 90 percent of your hardware investment sits idle most of the time. Virtualization allows you to use more of what you already have, pushing capital expenditures further into the future.
Virtualization has taken a firm hold at most enterprises these days, but the fact is we've only just begun to unleash the true potential of the technology. Our Arthur Cole spoke to analysts and industry experts to compile the following quick list of the ways virtualization can benefit your business.
