The SATA Backplane

The system supports a passive SATA backplane. The backplane provides the platform
support for peripheral drives and hot-swap SATA hard drives. To eliminate several cables,
the backplane is 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 SATA data from the drives to the
SATA controller on the server board or a SATA controller add-in card. It provides the
physical requirements for the hot-swap capabilities.
