SAS2-826EL Series Backplane User's Guide
Dual Host Bus Adapter
Inadualhost busconguration,the
backplane connects to two host bus
adapters.
Dual Host Bus Adapter Failover
If the expander or data path in Port
A fails, the system will automatically
fail over to Port B. This maintains a
full connection to all drives.

3-3 Failover with RAID Cards and Multiple HBAs
TheSAS2-826EL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.
IMPORTANT: For RAID controllers, redundancy is achieved
through port failover. For multiple HBAs MPIO software is
required to achieve failover protection.
