Physical DPM Server 2019 - Storage Spaces in mirror-mode supported for MBS? RRS feed

  • Question

  • Hello everybody,

    we plan to upgrade from DPM 2016 to (or doing a fresh install of) DPM 2019 (using Windows Server 2019) on a physical box which until now used a hardware RAID controller an a RAID 10 set of mechanical hard disks.

    According to https://docs.microsoft.com/en-us/system-center/dpm/add-storage?view=sc-dpm-2019 the described scenario is using storage spaces for DPM MBS, but in "single" mode and thus without fault tolerance. Can we use storage spaces on the physical DPM box (not a Hyper-V VM), add the hard disk to it and create a "mirror" virtual volume as the DPM modern storage pool?

  • Hi Stefan,

    As far as I know you can use mirroring for the virtual volumes.

    The best and recommended configuration though is to go with "Parity" because it is designed for capacity efficiency and increased resiliency, as "Mirror" is more designed for increased performance.

  • Thank you, Leon! If mirroring would not be supported I would be wondering why, but now I am confident. We will use mirroring simply for performance reasons. We used RAID5 longer ago for the DPM store and it was sooo slow. Never again.
