SAS/SATA Backplanes
The system can support either an active SAS (Product Code - ASR1500SASBP) or a
passive SAS/SATA backplane (Product 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.
The passive backplane acts as a 'pass-through' for the SAS/SATA data from the drives to
the SATA controller on the server board or a SAS/SATA controller add-in card. It
provides the physical requirements for the hot-swap capabilities. The active backplane
has a built-in SAS controller that does not need communication with the baseboard
controller or an add-in card.
