Windows Server 2016: storage spaces direct rdma requirement clarification? RRS feed

  • Question

  • So @ [https://technet.microsoft.com/en-us/library/mt126109.aspx] the snippet about RDMA requirements states "For production deployments, it is required to have an RDMA-capable NIC (or a pair of NIC ports)." I'm confused - does that mean I can use a non-RDMA-capable NIC that has 2 (or more) ports?

    RDMA is not a hard requirement. You can absolutely do S2D on your VM-based host for lab use w/out RDMA supported. See:

  • Sadly this is planning for a production environment, not a test lab. So non-rdma nic is 100% not a supported scenario (or anticipated to be, we're still in TP after all) for connecting physical hosts in production to form the storage spaces direct cluster?

  • Hi,

    From the article you mentioned, it is still in progress to define a hardware requirement. From my understanding, RDMA is highly recommended though we can still use S2D to get it work.
