Dear Community We have a stretched cluster as below. We have a couple of queries related to HA Settings & DRS Rules to be set for some VMs pinned to specific fault domain storage. Appreciate your quick response . ============ On both Data nodes , we have the management VMK now having 2 tags management + vsan witness and having management vlan x ip we have the VSAN VMK with just vsan tag with default gateway ( as gateway does not matter since network is l2 stretched ) having vsan data vlan y ip On the witness, we have management vmk0 having management tag and having management vlan A ip we have the vsan vmk1 with vsan tag and having the vsan witness vlan z ip ( routable with vlan x ) ========== 1. For the HA settings , is it ok if we just set a single HA isolation address ( ie gateway of vlan y ) via das.isolationAddress0 instead of the 2 recommended by VMWARE ? 2. We plan to pin some VMs to specific Fault domains via the below vsan policy settings . Our requirement is that in case of a planned maintenance activity ( other than disk failure ) , we are able to move the VM storage to the other site temporarily . For such VMs, which type of DRS rules is recommended ? Should or must ?
