Dual Host Bus Adapter
In a Dual Host Bus Conguration, the
backplane connects to two Host Bus
Adapters (HBA).
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.
6-4 Cascading Backplanes
The SC836 chassis supports cascading when coupled with an 836EL series back-
plane or other Supermicro backplane with Expander capabilities.
Power Control Card
In a cascaded conguration, backplanes can be linked to create "Just a Bunch of
Drives" or JBOD. The primary server requires a Host Bus Adapter (or motherboard).
The other servers require a Control Card or Power Card.
