On Hyper-v vs. ESX/ESXi my take has always been that vsphere is more mature, and if your hardware is on the HCL you just drop in the ISO and away you go.
With Windows you might get lucky "out the box" or you might be having to download Broadcom NIC drivers (and teaming software) or Intel NIC drivers (and teaming software). Not to mention technical support - could be wrong here and happy to be corrected but I don't think you can buy a cheap support agreement on hyper-v like you can vsphere? On a technical level, at that sort of size/scale I'm sure either would do the job admirably. ~ Finally, powerful endpoint security that ISN'T a resource hog! ~ ~ <http://www.sunbeltsoftware.com/Business/VIPRE-Enterprise/> ~ --- To manage subscriptions click here: http://lyris.sunbelt-software.com/read/my_forums/ or send an email to listmana...@lyris.sunbeltsoftware.com with the body: unsubscribe ntsysadmin
