Connecting an External Host Bus Adapter to the
Backplane
This backplane supports external HBAs. In this configuration, the HBA and the
backplane are in different physical chassis. This allows a JBOD (Just a Bunch Of
Drives) configuration from an existing system.
IMPORTANT: See Section 3-3 of this manual, Failover with RAID Cards and Multiple
HBAs for important information on supported configurations.
