  • Question

  • Hi,

    Is it a supported solution to make a hyperconverged S2D cluster, and ALSO install the scale out file server role ?

    So that the cluster can run VM's and ALSO act as a SOFS for other hyper-v servers.

  • Hi,

    Each of the nodes in the cluster are able to access the S2D storage. There would be no benefit to installing the SOFS role unless you wanted to store files other than the VM / VHDX files unless you wanted other servers outside the cluster to access the storage?

    Either way it is an option that can be enabled however much like running hyper-v along with domain services on the same node not advised,  as a hyperconverged S2D cluster should only run the hyper-v/storage roles for the VM's.

  • Hi Sam,

    I aware of the concept of S2D very well. Both converged (disaggregated) and hyperconverged.

    But the scenario would be obvious. You have a hyerconverged cluster with some vm's and a lot of fast storage to spare. Then you have, let's say, a "compute cluster" on top of a bladecenter without disks apart from OS.

    THEN you could have your vm's from both clusters run their vhdx's at the hyperconverged cluster.

    The question was just if it indeed was a supported scenario from MS.

  • Hi anker,

    I suggest you may check the thread discussed before about enabling both S2D and Failover Clustering for SoFS

  • Hi Mary,

    Im not sure where in that thread there is something that would indicate whether or not it is supported.

  • Hey Carsten,

    As far as we can see from this article https://technet.microsoft.com/en-us/windows-server-docs/storage/storage-spaces/storage-spaces-direct-overview SOFS is supported with Storage Spaces Direct.

    Please check this article on how to deploy SOFS with S2D: https://www.starwindsoftware.com/blog/microsoft-storage-spaces-direct-4-node-setup-2

    Also, if you have 2 or 3 node cluster, I would recommend you to go with StarWind Virtual SAN as a Shared storage for SOFS: https://www.starwindsoftware.com/scale-out-file-servers-sofs

  • alex,

    Im not sure it is said in that document, that its a supported scenario, and I don't understand why MS is not making that more clear. I think its a obvious solution.

  • Carsten, 

    SOFS with S2D is one of the deployment options for the converged scenario. That's the only document I've found regards the SOFS and S2D.

  • Hi Anker,

    I agree, I cannot see it not being supported by MS as you are simply running multiple clusters from the same storage hyperfconverged or not.

    As you are only storing vhdx files on the storage I cannot see Microsoft not providing support as this would mean any hyperconverged solution would be restricted to only allow storage use from the VM's sat in the same cluster.

  • alex,

    No it is not. there are two scenarios here. converged and hyper converged !

    converged is where hyper-v role is installed on "compute"-cluster and SOFS on "storage" cluster (on top of sd2)

    hyperconverged I where compute and storage is on the same, but here you would not normally use the sofs role (your vm's disk will have path like c:\clusterstorage\volume1 instead os \\sofs01\share01)

  • sam,

    I agree. just that I would like someone from MS to confirm that. not very funny to deploy my solution (a lot servers), and then when something goes wrong, MS will not give support because it is a solution not supported :-)

  • Carsten,

    I know the difference between scenarios. Via link I have provided there are deployment options and one of them is converged (dedicated or compute and storage separated) that could be deployed.

  • Hey Carsten,

    As far as we can see from this article https://technet.microsoft.com/en-us/windows-server-docs/storage/storage-spaces/storage-spaces-direct-overview SOFS is supported with Storage Spaces Direct.

    Please check this article on how to deploy SOFS with S2D: https://www.starwindsoftware.com/blog/microsoft-storage-spaces-direct-4-node-setup-2

    Also, if you have 2 or 3 node cluster, I would recommend you to go with StarWind Virtual SAN as a Shared storage for SOFS: https://www.starwindsoftware.com/scale-out-file-servers-sofs 

    This is an old thread I bumped in too, but to be clear:

    • The SoFS role is supported with Storage Spaces Direct when you are not hosting VMs on the same cluster.
    • The SoFS role is not supported when you are running VMs on the same cluster.

    You either choose for HyperConverged and run the VMs on the same cluster as the storage (so you do not need SoFS) or choose for Converged and let VMs consume their storage using SMB where the VMs run on a different cluster.

    For now atleast :-)

  • I knew this and I know I read this somewhere, but now I can't find it anywhere.. It says on the official site;

    "Storage Spaces Direct was designed for two distinct deployment options:" going into the converged and shared, but it's not explicit enough I think. I posted a sidenote on https://docs.microsoft.com/en-us/windows-server/storage/storage-spaces/storage-spaces-direct-overview which is a nice way for the community to add info like this!
