Handling different disk speeds in S2D RRS feed

  • Question

  • I am using S2D 2019 and i have 3 servers that between them have 3 CSVs using 3 SSDs and 10 10k HDDs.

    I want to add 10 7.2k HDDs to each server and create a CSV that will just use these disks? I dont want the disks to mix as the 10k disks are quite a bit faster.

    Is there any way to achieve this with S2D?

  • Hi,

    Thanks for posting in our forum!

    From your description, i know you want to create CSV with these 7.2k HDDs , but unfortunately, we can't do that.

    The storage pool will automatically choose which physical disks to use to create virtual disks, which we cannot control this behavior.

  • Unfortunately, S2D doesn’t give you much control and flexibility of physical storage. So you should rely on how S2D will balance a workload.

    If manual tiering is crucial for your environment, take a look at starwind vsan. The software can create different virtual disks based on underlying storage.
