Load balancing for a Virtual File Share
A Virtual File Share can also be associated with more than one Virtual CIFS Server,
enabling load balancing to be used. In the following example, the Virtual File Share
sh1 is assigned to the Virtual CIFS Servers 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.
