Imagine a scenario: you've got one machine, several drives (SSDs, of course). You want to have several virtual machines in that machine. These machines might be:

  • An active directory node
  • A SQL Server node (only the server, not the actual data store)
  • A web server node
  • Just a node that has, say, XP x64 and is used for computation

So what I'm wondering is: since VMs are just files on disk, should I bother with RAID? For example, instead of having several disks I could stripe and mirror everything into one drive and then have that.

Or maybe I should just have one VM per drive and forget about RAID?

    VM's, like any other files, work better with faster disk access. RAID can help that. What's your actual problem you're trying to solve?

RAID will give you physical level redundancy and your system will survive in case of drive's physical fault. So, I guess, if you need it - than go with RAID. If you can afford to lose data and/or spent time to recover your system - than do not do RAID setup.

RAID itself will not change anything for your VMs.
