Supported MSCS configurations on VSAN stretched clusters

[mike-p]

I search for an official document which states what cluster services are supported.

Thanks & Regards

Hello Mike,

Only non-shared disk implementations are supported natively with shared disk configurations being supported for vSAN iSCSI (and then this is not supported for presenting to ESXi):

Thanks Paul,

in addition to that i found this information about iSCSI services on vsan:

VMware Knowledge Base

"vSAN Stretched Clusters are not supported"

At the end there is no option to run MSCS/WSFC on vsan stretched clusters.

There is the option to use vSAN iSCSI presenting storage to MSCS/WSFC on non-stretched clusters. But as vSAN iSCSI is not supported on stretched clusters, if you only have stretched clusters then this is not a supported option. More information on some of the rationale of why this is not supported here:

The solution is on the way:

VMware vSAN 6.7 Update 3 Release Notes

• Windows Server Failover Clusters (WSFC) on native vSAN VMDKs. vSAN 6.7 Update 3 introduces native support for SCSI-3 PR, which enables Windows Server Failover Clusters to be deployed directly on VMDKs as first class workloads. This capability makes it possible to migrate legacy deployments on physical RDMs or external storage protocols to vSAN.
