SAS/SATA Backplanes
The hot-swap hard drive system (Product Code: SR1600URHS)
can support either an
active SAS (Product Order Code: ASR1500SASBP) or a passive SAS/SATA backplane
(Product Order Code: ASR1500PASBP). The backplanes provide the platform support for
peripheral drives and hot-swap SAS or SATA hard drives. To eliminate several cables, the
backplanes are also used as a pathway for signals from the server board to various
platform interconnects, including those for the control panel and peripheral drives.
Active Backplane
The active backplane has a built-in SAS controller that does not need communication with
the baseboard controller or an add-in card. The following diagram shows the location for
each connector found on the active backplane.
