VMware announced details of its forthcoming Virtual Infrastructure 3.5 on Monday, including an experimental feature to shut down servers if they're not necessary.
The feature, called Distributed Power Management, monitors how hard servers are working and moves virtual machines to new machines to let unneeded servers be shut down. When workload picks up again, the servers are powered up again, according to the publicly traded EMC subsidiary.
Virtual Infrastructure includes two main components. First is ESX Server, the underlying hypervisor that lets a single physical computer run multiple operating systems simultaneously in compartments called virtual machines. Second is VirtualCenter, which lets administrators monitor and manage those virtual machines.
