Setting Up Your Storage Subsystem
Active-Active Single-Port: Host Cabling
Choose this topology when your application requires a high-
performance, robust, full system-level fault-tolerant disk storage
solution and transparent controller failover/failback. This dual
controller configuration supports a host with a single-port HBA
and is ideal when the host driver software does not support LUNs
that appear twice.
Note:
This configuration requires you to have two 6200S RAID
controllers installed in the storage subsystem.
