I couldn't find a clear answer online on if a mirror accelerated parity was supported when using a 2 host fail over cluster with shared DAS storage. This is not a S2D setup.

    Hi

    Based on my knowledge and a lot of searches, I think it is supported.

    For some reference links, please see:

    Hey,

    Check the following article to read more about ReFS. https://video2.skills-academy.com/en-us/windows-server/storage/refs/refs-overview
    As mentioned in the article, mirror-accelerated parity setups are supported for using with S2D only. Technically you can configure MAP withoug S2D and it will work, however, it wouldn't be supported.

    In case you want to deploy a 2 node cluster on you existing storage, you can use StarWind VSAN free as a shared storage option.
