Chapter 5 Connecting Data Hosts to the 2530 Array 65
FIGURE 5-3 Direct Connections from Three Data Hosts with Dual HBAs
Note – For maximum hardware redundancy, you must install a minimum of two
HBAs in each host. Dual-port HBAs give you two paths into the storage array but do
not ensure redundancy if the HBA fails.
Before you connect data hosts directly to the array, check that the following
prerequisites have been met:
■ Interface cables are connected and between the HBAs and the array controllers.
■ SAS cables (1-, 3-, or 6-meters) are available to connect the controller’s host ports
to the data host HBAs.
Each controller module on a controller tray has three SAS host ports (
FIGURE 5-4).
