Vsphere & MSCS Support

[Mad_scotsman]

Have read the support article on vsphere and MSCS and i am a little confused by it.

On page 11 it lists limitations and has the following

The following environments and functionality are not supported for MSCS setups with this release of vSphere:

Clustering on iSCSI or NFS disks

Does that mean just datastore disks? Is it okay if the base os is on a nfs disk and the clustered disks are san connected by microsoft iscsi in the guest client? Or is no iscsi supported kind of a blanket statement which im looking for some clarification on.

It is perfectly ok for OS vmdk's to live on iSCSI or NFS. The shared storage for a cluster is not supported on iSCSI or NFS.

Please award points if this helped.

Thanks,

K however when you mean the shared storage is not supported on iscsi does that include Microsoft iSCSI Software initiator to a lun in the gues os?

does that include Microsoft iSCSI Software initiator to a lun in the gues os?

In this case is Microsoft that must support, cause isn't related to a VMware configuration specific for application cluster (like vmdks sharing).

I have used Windows 2008 Failover clusters in exactly this configuration before - boot volume on iSCSI SAN, and data volumes on iSCSI SAN connected via iSCSI initiator inside the virtual machine. I have received support from both VMware and Microsoft in this configuration.

I like setting up clusters in this way due to the flexibility, the use of enterprise features like VMotion, and the use of SAN software for snapshots of data volumes, replication, etc.
