Connecting a PowerEdge Cluster to a Tape Library
To provide additional backup for your cluster, you can add tape backup devices to your cluster configuration. The Dell PowerVault™ tape libraries may contain an integrated Fibre Channel bridge, or Storage Network Controller (SNC), that connects directly to your Dell/EMC Fibre Channel switch.
Figure 2-12 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. Using this configuration allows you to add more servers and storage systems in the future, if needed.
NOTE: While tape libraries can be connected to multiple fabrics, they do not provide path failover.
