If you haven’t got Microsoft’s Virtual Machine Manager suite and you don’t want to spend many hours backing up the source server, creating a blank VM, installing a base O/S and then hoping a restore will work without hours of troubleshooting disparate hardware issues… really?!?! there is a handy alternative from those clever folks at Sysinternals – disk2vhd.įrom Sysinternals “Disk2vhd is a utility that creates VHD (Virtual Hard Disk – Microsoft’s Virtual Machine disk format) versions of physical disks for use in Microsoft Virtual PC or Microsoft Hyper-V virtual machines (VMs). Online Windows server capture using Sysinternals Disk2vhd utility
all generating high heat output (which in turn has high cooling costs). Older systems consuming a relatively high amount of energy and space for what is now very low processing power, can be converted to VM’s hosted on much more powerful hardware for a similar footprint but with much increased agility through the well understood benefits of virtualisation.Ī recent project The Full Circle ( undertook as part of our private cloud practise, was to rationalise several older HP ProLiant D元60 servers (one had a BIOS dated – over 10 years old!) each taking 1U of rack space, some with dual power supplies, dual network adaptors, mirrored disks, etc.
Taking a legacy platform often on older, unsupported hardware and software, and converting it to a virtual machine running with many other machines, but on new, high capacity hardware taking up less space and power is a key driver for virtualisation. The ability to convert existing Physical hosts to Virtual machines is often the biggest return on investment benefit to justify the case for virtualisation.
