Windows failover cluster on VMware 5.5

I am on a VMware 5.5 environment and I want to create a Windows Failover Cluster with 2 nodes. I do not want both nodes on the same physical host (cluster-in-a-box) so I am looking for Cluster-across-box configuration. However I would also like the nodes to vMotion should their host dies. Is there a cluster-across-box config that supports vMotion? If yes, do I need to use Pass-Through RDM (physical compatibility mode) or Non-pass-through RDM (virtual compatibility mode)? Thanks.

Just a quick point, vMotion is not used when a host dies, VMware HA is used, which just restarts the VM, on other available hosts, when a host has an uncontrolled shutdown e.g. host crashes, dies, fails etc

VMware recommends physical compatibility mode.

You will need to use RDM for all Microsoft Failover Clustering.

See pages

Pg15 - Cluster Virtual Machines Across Physical Hosts

and

Pg22 -  Use MSCS in an vSphere HA and vSphere DRS Environment

see the Failover Clustering Bible

Hello Andrew and thank for the reply. Yes, VMware HA is what I meant. Does physical compatibility mode support VMware HA? Or is the VM "tied" to the host?

VMware HA is supported, VMs are not tied to a host, and you would want to setup Anti-Affinity Rules, see Page 22 of the Guide, to ensure VMs are on different Hosts, if you have DRS.

you can see the supported matrix here

Okay thanks. I have been interpreting "pass-through RDM" as a pass-through SCSI connection and in this case the VM is tied to the corresponding host. I suppose this is what has been causing my confusion. :-)

It's pass through iSCSI or FC connection to shared storage!
