Adding iSCSI external storage

The system supports iSCSI connections to systems that are used as external storage.

Unlike Fibre Channel connections, you need to manually configure the connections between the source system and these target external storage systems. Direct attachment between the system and external storage systems is not supported and requires Ethernet switches between the system and the external storage. To avoid a single point of failure, a dual switch configuration is recommended. For full redundancy, a minimum of two paths between each initiator node and target node must be configured with each path on a separate switch.

In addition, extra paths can be configured to increase throughput if both initiator and target nodes support more ports. The system supports a maximum of four paths per node.
