Chapter 5: Installing the Controller and Disk Drives

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
1
backplane. (Refer to your system's documentation for more
information.)
Use an internal SAS cable to connect the controller to the backplane.
