Implementing Shared Storage

The precise method of deploying any given shared storage scheme will vary depending on the hardware and software you are using.

The basic process is to:

  1. Implement the shared storage first
  2. Connect the Hyper-V hosts to it
  3. Add the hosts into a Failover Cluster.

Cluster Shared Volumes

  • Cluster Shared Volumes are volumes in a failover cluster that multiple nodes can read from and write to at the same time
  • This feature enables multiple nodes to concurrently access a single shared volume
  • CSV is supported on WS2008R2 and newer
  • Failover Cluster Manager
    • CluAdmin.msc
  • CSVs are created from Physical Disk Resources (PDR)
  • Must pass all tests in the Validate a Configuration Wizard
    • Included in the Failover Cluster Manager MMC snap-in
  • Use matching computers that contain either the same or similar features
  • You cannot use teamed network adapters with iSCSI

Failover Clusters

See also Hyper-V Cluster.

  • All servers in the cluster must be in the same Active Directory domain
  • Use basic disks, not dynamic disks
  • Format the partitions with NTFS
  • Partition disks with MBR or GPT partition tables
  • Do not expose the clustered volumes to servers that are not in the cluster
  • A witness disk holds a copy of the cluster configuration database
  • Failover Clusters can use Cluster Shared Volumes
  • Use Microsoft Multipath I/O (MPIO) for highly available storage
  • :?: Requires Windows Server 2008 R2 Enterprise or Windows Server 2008 R2 Datacenter
    • Also available on Hyper-V Server 2012

Two-Node Cluster

  • For a two-node failover cluster, the storage should contain at least two separate volumes (LUNs) configured at the hardware level
    • One volume will function as the witness disk
    • One volume will contain the files that are being shared between the cluster nodes
      • This volume serves as the shared storage on which you will create the virtual machine and the virtual hard disk
