CLUSTER in Hyper-V Server 2008 R2

    Question

  • I'll set up a cluster of virtual machines with Hyper-V Server 2008 R2. I've done this with the iSCSI protocol and standard network interface cards. Now I will have cards by connecting to a fiber optic storage.

    I'm having doubts. How is the configuration of the HBA cards in Hyper-V Server? In the case of iSCSI, I used the graphical interface.

    Any recommendations?

  • Hyper-V doesn't really care about the underlying storage.  Clustering cares whether the storage supports SCSI-3 Persistent Reservations.  If so, then the storage is supported for Clustering. 

    Depending on the HBA and Storage vendors, there will be proprietary drivers for each.  Your storage vendor will be your best source of information about that.

  • As Geoff mentions, the hypervisor (Hyper-V) does not care about the storage nor how it connects.

    The type of storage you have and how you set up that storage can define / limit how you can use it.

    If you have a single host and you connect to a LUN using an HBA, then you can use this volume of storage in two ways - present as a passthrough disk to a VM or store virtual disks on it.

    IF the volume is to be used by Failover Clustering as a CSV - then you need to define your cluster properly and all of hte hosts participating in the cluster must be connected to it prior to adding them to the cluster.  (basically, configure it before you create the cluter).

    Beond some generalizations I gess that we would need to know more about your particular situation.

  • I was worried about configuring the connection itself. I'll ask IBM how is this configuration.

    Has anyone done a cluster of virtual machines with Hyper-V server and a Fibre Channel storage?

  • Lots of folks have.

    iSCSI is not the only way.

    There is also the clustering TechNet forum - lots of clustering Hyper-v questions happening there as well.

  • I'll second that. I just have created a Hyper-V Cluster with an IBM Bladecenter H (4 Blades) with a DS3900 connected over FC.

  • Just to add some comments here from the field....

    FC SAN + Hyper-V R2 works like a charme ;-)

    As Geoff already stated the storage need to be Windows 2008 aware (SCSI-3 PR) and if you want to get support for your FC your hardware need to be Windows 2008 certified and pass the validation tests.

    For server core installations there are normally 3rd party packages which can be used for installation/configuration, guidelines recommended. I'm personally aware of emulex and brocade FC's.
