38 Cabling Your Blade Cluster Hardware

NOTE: If you are using other Dell/EMC storage systems for the configuration

shown in Figure 2-6, you can also connect the remaining iSCSI ports 2 iSCSI and

3 iSCSI (not shown) depending on the required level of redundancy.

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 2-7 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.
