At our termly IT staff meeting last week, one of the subjects we talked about was the increasing use of virtual servers. About two thirds of the central servers at Sussex are now virtual. That means they aren’t bound to specific hardware in the data centre and in the event of a hardware failure, we can get the virtual servers back up and running very quickly simply by moving them over to a different platform.
But the really big benefit comes in the power usage. Virtual servers can be transferred between physical devices to ensure the hardware is being used as efficiently as possible and that means big savings on electricity bills.
