MSCS support, one physical node, one virtual node in an cluster

    Question

  • Is clustering Windows 2003/2008 server across one physical node and one virtual node on supported in a production environment by Microsoft? The attempt is to cluster vCenter server. I know VMware has Server Heartbeat but the client is reluctant to use it, they are also reluctant to virtualize both servers. Thanks.

  • In 2008 as long as it passes Validate it is supported.  Do you know how to make vCenter highly available in WSFC?  If so, what steps are you following?

  • Remember that clustering W2K3 is still bound by the rules for the Windows Server Catalog/HCL for supported hardware.

    W2K8 doesn't care - as long as it passes Cluster Validation, it's technically a valid architecture.

    So in terms of W2K3 I'd say no.

    In terms of W2K8 technically yes, but I wouldn't do it.

  • I don't think that it will pass validation or it will be supported because the validation test will check for:

    1-    Hardware differences.

    2-    Drivers & firmware  differences.

    3-    Storage arbitration.

    In a physical – virtual configuration all of this tests will fail. So I think that you need to setup a two virtual nodes cluster or a two identical physical nodes cluster.
