Yesterday we had an HP Atom based PBX appliance develope hardware problems. (hardrive or controller) Our pre planned disaster recovery plan was to restore a nightly Windows Image backup of the Windows7 appliance into a Hyper-V VM on an HP Proliant ML350 server.
The restore went without a hitch! (After realizing that the target VM needs to be bigger than the source image backup--my fault entirely) It took roughly 1.5hours to restore a 160GB Windows7 image into a Hyper-V VM. And the virtual machine booted and the restored Windows OS ran perfectly. In fact the snom ONE Blue Windows based PBX came up fully activated and ready to roll. This makes using snom ONE in a senario where you need a hot spare a very nice solution.
One thing that was unexpected was the fact that snom ONE pbx runs MUCH FASTER as a Hyper-V Virtual OS than on dedicated Atom hardware. It was immediately noticable on the web interface of snom ONE. In fact I'm starting to wonder: If Hyper-V is already in place, is there a need for a dedicated appliance?
As always, I'd like to hear your input.
