Proxmox without ZFS and HA , is it possible?

[m3a2r1]

I've got 3 nodes of pve and NFS share for vms hard disks outside the cluster. Is it possible to run working HA without ZFS (I have got physical RAID and I'm going to change to ZFS in future)?.

HA and ZFS are not related at all.. for HA you need at least 3 nodes and some kind of shared storage
