What do you need to know about VSAN failover clusters?
Failover Clusters (WSFC). It supports SCSI-3 Persistent Reservations (SCSI3PR) on a virtual disk level required by WSFC to arbitrate an access to a shared disk between nodes. Support of SCSI-3 PRs enables configuration of WSFC with a disk resource shared between VMs natively on vSAN datastores. Currently the following configurations are supported:
