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.

- 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.
