Organisations are under mounting pressure to develop ‘greener’ approaches towards their information technology (IT) practices, and IT and business leaders need to wake up to the issues of spiralling energy consumption and environmental legislation, according to Gartner, Inc. Although technology can help reduce the impact of some environmental problems, its potential harmful effect is receiving increasing attention from environmentalists and policy makers alike.

Mr Kumar said, “The power needed for a rack of high-density server blades can be between 10 and 15 times higher than the power needed for a traditional server environment. Most legacy data centres built 15 to 20 years ago cannot meet this demand. At the same time, a similar amount of additional power will be needed to remove the huge quantity of heat generated by these new machines. If the machines are not cooled sufficiently, they will shut down, with potentially damaging consequences for business service levels and IT governance.”

It’s not just datacenter capacity that remains the issue, the actual cost of energy is increasing, this in the end will be passed on to the banks and organizations renting datacenters, coupled with the drive for carbon reduction makes consolidation the target for 2007, whether it’s using virtualization or a more effective way of providing IT.

Vmware has the business case, we need to virtualize in a big way properly.  IT needs to stop thinking “… team need a DL380″, no they don’t, they need something to process, store and facilitate their application. IT needs to stop thinking in essence, “right another box, great, more revenue”, it’s a service we’re providing, and under current conditions we can’t keep throwing physical hardware as the service fix.

Providing a virtual infrastructure is the way to go, whether it’s a rack of blades/rackmounts all SAN attached, all with ESX, vmotion and virtual center. It should be in essence a floating IT infrastructure, server on demand, as one ESX server fills up, we start moving sessions around – a service, a virtual session, a virtual box.
