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 a BPN-SAS2-836EL
series backplane 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.
