Question

MSCS (Microsoft Server Cluster)


Does AHV supports MSCS ? I am aware about two node windows cluster with witness VM mentioned in below :

But just want to confirm if it supports MSCS with shared storage including quorum?

i think using iSCSI Volume Group you can have a shared storage over network for Quorum and other data for your VM's
i am currently using it in ESXi, but i think it should be the same concept in AHV.
Hi Rekha,,

You can use volume group which is Nutanix Volumes (ABS) for this use case, Nutanix volumes uses scsi-3 persistence for MSCS, You can use data services ip as iscsi target without using iscsi mpio.

Fail over clustering is not supported on NFS storage platforms. You would need to present external iSCSI storage to the cluster for failover clustering. If you're looking at an always on cluster for like SQL, and it's essentially just a continuous copy, then yes it's supported. It's not a hypervisor issue it's an NFS incompatibility from Microsoft. Nutanix has "supported" methods, but you need to work with support.
