I've got an old server and I would like some advice on the RAID configuration. I have 8 disks of 300GB. And I'm not sure which setup is more desirable.

  • 2x RAID1 (os: hyper-V)
  • 6x RAID5 (VMs)

or

  • 8x RAID5

    • If I choose for 8x RAID5, will the host OS see it as one disk or can that be changed in the Array Controller?
    • Is partitioning in the host OS desirable?

I would not recommend you using RAID5. The following thread describes it. RAID with three disks (RAID 5 vs RAID 1E) In addition, assuming your drives are HDDs, you will get low random write performance, which can be critical for VMs. I would recommend you going RAID10 for your VMs it will give you decent performance.
