You can create a MSCS cluster that consists of two or more virtual machines on two ESXi or more hosts.

About this task

A cluster across physical hosts requires specific hardware and software.

  • ESXi hosts that have the following:

    • Two physical network adapters dedicated to the MSCS cluster and to the public and private networks.

    • One physical network adapter dedicated to the VMkernel.

  • Supported shared storage configuration. For more information, see Supported Shared Storage Configurations.

  • RDM in physical compatibility (pass-through) or virtual compatibility (non-pass-through) mode. VMware recommends physical compatibility mode. The cluster cannot use virtual disks for shared storage.

    Failover clustering with Windows Server 2008 is not supported with virtual compatibility mode (non-pass-through) RDMs.
