C-12 Failover with RAID Cards and Multiple HBAs
The BPN-SAS2-836EL backplane may be congured for failover with multiple HBAs
using either RAID controllers or HBAs to achieve failover protection.
RAID Controllers: If RAID controllers are used, 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 congured to perform
the load balancing and failover tasks.

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.
