A dual-controller module configuration improves application
availability.
If a controller module failure occurs, the affected
controller module fails over to the partner controller module with little interruption
to data flow. A failed controller module can be replaced without the need
to shut down the storage system.
In a dual-controller module system, hosts
use LUN-identifying information from both controller modules to determine
the data paths are available to a volume. Assuming
MPIO software is installed, a host can use any available data path
to access a volume that is owned by either controller module. The path providing
the best performance is through the host ports on the controller module that owns the volume
. Both controller modules share one set of 1,024 LUNs (0-1,023)
for use in mapping volumes to hosts.
