Virtualisation_delivers_impressive_savings_for_server_farms

The economic downturn has prompted more businesses to deploy green IT practices, some of which are reaching energy savings of up to 80 per cent, a claim suggests.

According to James Murray, editor of BusinessGreen.com, firms are realising that as well as the case for the environment, energy-efficient practices can in fact deliver impressive enterprise savings.

For companies with server farms, virtualisation can provide energy savings of between 70 and 80 per cent, he states, adding that there is a strong commercial case for such improvement of an IT infrastructure.

Check out this article talking about virtualization and energy savings. It can be an impressive way of achieving more with less, of reducing your costs and it’s always good to read what others are talking about in this space. You gain empowerment through virtualization of the server estate through:

Reducing hardware support costs - particularly if you consolidate from different server types to fewer – the less range in your hardware support cost, and the younger your servers, typically the lower the cost. For example 16 types of Compaq Proliant to two types of HP/IBM blade?

Energy efficiency – you should be able to consolidate many physical servers to one physical server, fewer servers providing the infrastructure, coupled with ideally things like SAN boot, energy efficient processors and power supplies.

Business empowerment – possibly the most important one, being able to deploy and roll back more on demand in line with the business need – that we can provision/reconfigure servers more quickly, a memory upgrade need not be a three week process.

Disaster recovery opportunities – could your disaster recovery data center be consolidated to require less data center power and space? Do I need all those rack servers, or a batch of blades?
