Where should I store the VM files (config, snapshots, vhd) on a Hyper-V server?

By default the VHDs go into “C:\Users\Public\Documents\Hyper-V\Virtual Hard Disks” and the config files go into “C:\ProgramData\Microsoft\Windows\Hyper-V”.

Should I leave them there?

Is it ok for the VHDs to be in a “Public” folder?

• Here is what I do:

  • I have pretty much always a RAID 10 for the Hyper-V host, 4 discs. Either BLack Scorpio (lower performance) or Velociraptors.

  • 64gb base partition

  • The rest is a second partion "V:"

  • VM's live on V.

  • Public is not ok - i mean, seriously, what for?

  aduljr : you don't want your server images on a public drive. I would keep the server images on a separate disk system of either raid 1 or raid 10 depending on your performance needs, snapshots I would store on a different drive or storage server for backup and retrieval purposes. I guess the question to really ask is, what are you doing to begin with? Are you learning within a home environment or lab setup? Or is this going to be something that will go into production?

  TomTom : Well, normally the OS discs basically do nthing. After startup you can ignore them - as long as nothing else than hyper-v runs on them.The Raid 10 stops me from having to have more discs in. Me personally I do that with a lot of setups - sometimes quite high performance (32gb server, 4 cores, running sql server with directly mapped discs for the real data).

• In general, you'll want your VMs on a disk subsystem that is redundant and shared with every member of the Hyper-V cluster. This will almost never be C:.
