Deploy two-node S2D, run file server and hyper-V virtual machine

hello,everyone.I have two servers (3 SSD+8 HDD,512GRAM) of the same model, but no RAID, so I want to deploy two-node S2D to create a cluster, mainly to run the file server and Hyper-V roles to prevent a single disk failure from causing server failure. But I don’t know what happens to the cluster after a node fails, whether the S2D storage can still operate normally, whether the file server and virtual machine are normal, and what should be paid attention to? Thank you.

    Hi,

    If you only have two nodes to deploy an S2D cluster, it is recommended that you use the two-way mirror. In this case, the S2D cluster fault tolerance is to allow one node to fail.

    At the same time, in the two nodes cluster, it is recommended to configure cluster witness, file share witness or disk witness, so as we can ensure the cluster can running with one node.

    The following article is the detailed information about fault tolerance of S2D for your reference:

    https://learn.microsoft.com/en-us/windows-server/storage/storage-spaces/storage-spaces-fault-tolerance

    Thanks for your time!
    Best Regards,
    Anne
