Cabling Dell EqualLogic iSCSI Storage System
Host servers can be attached to the Dell EqualLogic iSCSI array through an
IP storage area network (SAN) industry-standard Gigabit Ethernet switch.
Figure 5-1 shows the recommended network configuration for a dual control
module PS5000XV array. This configuration includes two Dell PowerConnect
54xx Gigabit Ethernet switches, to provide highest network availability and
maximum network bandwidth.
It is recommended that you use two Gigabit Ethernet switches because in
the event of a switch failure in a single ethernet switch environment, all
hosts lose access to the storage until the switch is physically replaced and
the configuration restored. For such configurations there should be multiple
ports with link aggregation providing the inter-switch, or trunk connection.
Additionally, it is recommended that one Gigabit interface connects to one
Ethernet switch from each of the control modules, and the other two Gigabit
interfaces connect to the other Ethernet switch.
