Connecting the Front and Rear Backplanes
This section describes the cables used when cascading from the front backplane
to the rear backplane from multiple HBAs. These connections use CBL-SAST-0531
internal cables and CBL-SAST-0573 external cables.
Figure E-1: Dual HBA Configuration
IMPORTANT:
See Section D-13 of this manual,
Failover with RAID Cards and
Multiple HBAs
for important information on supported configurations.
