Cabling One PowerEdge Server Enclosure to a Tape Library
To provide additional backup for your cluster, you can add a tape backup
device to your cluster configuration. The Dell PowerVault™ tape libraries
contain an integrated Fibre Channel bridge or a storage network controller
(SNC) that connects directly to your Dell|EMC Fibre Channel switch.
Figure 2-5 shows a supported PowerEdge cluster configuration using
redundant Fibre Channel switches and a tape library. In this configuration,
each of the cluster nodes can access the tape library to provide backup for
your local disk resources, as well as your cluster disk resources.
NOTE:
While tape libraries can be connected to multiple fabrics, they do not
provide path failover.
