Windows 2008 MSCS over iSCSI in vSphere 4.1

Is it possible to configure MSCS on Windows 2008 running with iSCSI (In-Guest)?

Yes... in the case from VMware side you will see only the C: disk and nothing more (of course also the iSCSI VNIC).

Is it a supported setup?  I've read some other posting that MSCS over iscsi in vSphere 4.1 is not supported.

According to http://kb.vmware.com/kb/1037959 In-Guest iSCSI is supported. I actually have a customer who runs his MSCS this way and never had any issues so far.

Is not supported if you implement RDM with iSCSI at VMware level...

In this case only FC is official supported.

Reading through the documentation it looks like in-guest iscsi is supported.

If using FC it must be via RDM (which means no warm vmotion Smiley Sad)

In-guest iSCSI is supported

From the documentation:

Fibre Channel – Configuration using shared storage for Quorum and/or Data must be on Fibre Channel (FC) based RDMs

In-guest iSCSI software initiators – VMware fully supports a configuration of MSCS using in-guest iSCSI initiators, provided that all other configuration meets the documented, supported MSCS configuration
