Virtualisation could save companies millions of pounds and be the dominant data-centre technology within the next two to three years, according to analysts.
Virtualisation can reduce energy consumption and cut operating costs for companies adopting the technology, according to Butler Group's Infrastructure Virtualisation report.
The report estimates a company currently operating 250 dual-core servers can save £2m over the next three years by adopting virtualisation technology.
Butler Group also estimates that a power saving in the order of £78,000 for every 1,000 PCs per year can be made by businesses moving from a full desktop PC infrastructure to a server-hosted desktop virtualisation set-up.
And a further £4,000 per 1,000 help-desk calls per month could also be saved by reducing the number of help-desk calls and encouraging the use of self-service application virtualisation technologies, the research reveals.
Many companies initially adopt virtualisation to save money through server consolidation, and then start to notice other benefits, so that virtualisation becomes part of the overall IT plan, according to the analyst house.
Roy Illsley, senior research analyst with Butler Group, said companies need to understand what virtualisation can deliver — and how it is delivered — to successfully use the technology to manage an organisation's IT resources.
