Dual Host Bus Adapter
In a Dual Host Bus Conguration, the
backplane connects to two Host Bus
Adapters (HBA).

Failover
If the Expander or data path in Port A
fails, the system automatically switches
to Port B. This maintains a full connec-
tion to all drives.

IMPORTANT: For RAID controllers, redundancy is achieved
through port failover. For multiple HBAs MPIO software is
required to achieve failover protection.
C-12 Failover with RAID Cards and Multiple HBAs
The SAS2-216EL backplane may be congured for failover with multiple HBAs using
either RAID controllers or HBAs to acheive failover protection.
RAID Controllers: If RAID controllers are used, then the failover is accomplished
through port failover on the same RAID card.
HBAs: If multiple HBAs are used to achieve failover protection and load balancing,
Linux MPIO software must be installed and correctly congured to perform
the load balancing and failover tasks.
