SAS/SATA Backplanes
The hot-swap drive system can support either an active SAS backplane (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.
