Intel SR1500AL manual SAS/SATA Backplanes, Active Backplane Components

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.
