n
All hosts must be running ESXi 6.0.
n
Mixed cluster nodes running FC or FCOE and iSCSI are not supported.
n
Mixed mode of iSCSI config is supported. For example, Node A on ESXi with iSCSI software initiator
and Node B on ESXi with Qlogic, Emulex or Broadcom hardware adapter.
n
Mixed mode configurations of ESXi 6.0 with previous ESXi releases are not supported.
n
Rolling upgrades of cluster Hosts from previous versions of ESXi to ESXi 6.0 builds are not
supported.
FCoE Support for MSCS
ESXi 6.0 supports FCoE storage and up to 5 node MSCS clusters using Cisco FNIC and Emulex FCoE
adapters.
n
ESXi 6.0 supports FCoE for Windows Server 2008 SP2 and above releases. Windows Server 2003 is
not supported.
n
Cluster-across-box (CAB) and cluster-in-a-box (CIB) are supported. A mixture of CAB and CIB is not
supported.
n
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.
n
In a CIB configuration all virtual machines must be on the same host.
n
No qualification is needed for SWiSCSI and FCoE initiators in a guest operating system.
n
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.
n
Standard affinity and anti-affinity rules apply for MSCS virtual machines.
n
All hosts must be running ESXi 6.0.
n
All hosts must be running FCoE initiators. Mixed cluster nodes running FC and FCoE are not
supported.
n
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.
n
Mixed mode configurations of ESXi 6.0 with previous ESXi releases are not supported.
n
Rolling upgrades of cluster hosts from previous versions of ESXi to ESXi 6.0 builds are not
supported.
vMotion support for MSCS
vSphere 6.0 adds support for vMotion of MSCS clustered virtual machines.
