32 Cabling Your Cluster Hardware
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.
