Connecting to a System Backplane

In a backplane connection, disk drives and SAS cards are attached to and communicate with
each other through a system backplane.
The number of disk drives is limited to the number of slots available on the backplane. Some
backplanes have embedded SAS expanders and can support up to 128 end devices. (For more
information about backplane and expander connections, see
Connect one or more internal SAS or SATA disk drives to the backplane. (Refer to your
1
system's documentation for more information.)
Use an internal SAS cable to connect the controller to the backplane.
