The wonder of Hyper-V
With Hyper-V, it's easier than ever to take advantage of the cost savings of virtualization through Windows Server 2008 R2. Optimize your server hardware investments by consolidating multiple server roles as separate virtual machinesrunning on a single physical machine, efficiently run multiple different operating systems in parallel, on a single server, and fully leverage the power of x64 computing.We have rolled out Hyper-V in our office and now have no physical Windows Servers that provide services. The only bare-metal servers run Hyper-V.Storage is dealt with by an HP DL380 server set up as a SAN so that the Hyper-V front-end servers connect via iSCSI to the SAN.Front-end servers are now:HP DL160 G5, 2 x 2.0GHz Xeon Quad-core CPUs with 32Gb RAMHP DL160 G6, 2 x 3.04GHz Xeon Quad-core CPUs with 64Gb RAM
