VFS1, VFS2, and VFS3. The Virtual File Share is configured identically on
each Virtual CIFS Server.
Node 1 is primary for Virtual CIFS Server VFS1, node 2 is primary for
VFS2, and node 3 is primary for VFS3. Each node is a backup for the other
Virtual CIFS Servers. CIFS clients connect to the load balancer (such as
round-robin DNS or a hardware load balancer) and the clients are then
routed to one of the nodes. If a node goes down, its clients will be failed
over to a backup node and access will continue.

All servers are providing Virtual File Share s1 via Virtual CIFS Servers VFS1,
VFS2, and VFS3. DNS round robin or a hardware load balancer is configured
to route the CIFS clients to a Virtual CIFS Server on first connect or on a
reconnect after a failure.
