6.5.1

n
Mixed mode of iSCSI cong 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 congurations 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 congurations are supported with some cluster nodes on physical hosts. In a CAB conguration, a
max of one virtual machine in a host can see a LUN.
n
In a CIB conguration all virtual machines must be on the same host.
n
No qualication is needed for SWiSCSI and FCoE initiators in a guest operating system.
n
N+1 cluster conguration, in which one ESXi host has virtual machines which are secondary nodes and
one primary node is a physical box are supported.
n
Standard anity and anti-anity 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 conguration 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 congurations 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.
Pre-requisites for vMotion support:
n
vMotion is supported only for a cluster of virtual machines across physical hosts (CAB) with pass-
through RDMs.
n
The vMotion network must be a 10Gbps Ethernet link. 1Gbps Ethernet link for vMotion of MSCS
virtual machines is not supported.
n
vMotion is supported for Windows Server 2008 SP2 and above releases. Windows Server 2003 is not
supported.
n
The MSCS cluster heartbeat time-out must be modied to allow 10 missed heartbeats.
n
The virtual hardware version for the MSCS virtual machine must be version 11.
Modifying the MSCS heartbeat time-out:
