True, but then one could setup a HA server for the management server.
And probably some load balancer(s) to cater for high availability.

both? Many NAS devices offer both iSCSI & NFS / SMB / CIFS.
Ideally, I want to setup a scalable SAN, with reliability in mind on a
RAID 6 / RAID10 concept, but need each client to only connect to the
