ESXi 6.0 supports FCoE storage and up to 5 node MSCS clusters using Cisco FNIC and Emulex FCoE adapters.

  • ESXi 6.0 supports FCoE for Windows Server 2008 SP2 and above releases. Windows Server 2003 is not supported.

  • Cluster-across-box (CAB) and cluster-in-a-box (CIB) are supported. A mixture of CAB and CIB is not supported.

  • CAB configurations are supported with some cluster nodes on physical hosts. In a CAB configuration, a max of one virtual machine in a host can see a LUN.

  • In a CIB configuration all virtual machines must be on the same host.

  • No qualification is needed for SWiSCSI and FCoE initiators in a guest operating system.

  • N+1 cluster configuration, in which one ESXi host has virtual machines which are secondary nodes and one primary node is a physical box are supported.

  • Standard affinity and anti-affinity rules apply for MSCS virtual machines.

  • All hosts must be running ESXi 6.0.

  • All hosts must be running FCoE initiators. Mixed cluster nodes running FC and FCoE are not supported.

  • Mixed mode FCoE configuration is supported. For example, Node A on ESXi with an FCoE software adapter intel based card and Node B on ESXi with an Emulex or Cisco FCoE hardware adapter.

  • Mixed mode configurations of ESXi 6.0 with previous ESXi releases are not supported.

  • Rolling upgrades of cluster hosts from previous versions of ESXi to ESXi 6.0 builds are not supported.
