Functional Description 43
5.9 SATA
The SBC347A provides up to four SATA interfaces. One port is connected directly
to the onboard SSD device, and the other three are routed to the VPX backplane
connectors for connection to off-board peripherals such as hard disk drives or
CD/DVD drives, as follows:
NOTE
SATA Port 2 is Only available when I/O product option = 1.
All backplane ports are capable of operating at SATA Revision 3.0 data transfer
rates (up to 6 Gbit/s).
NOTE
Due to limitations in the VPX backplane bandwidth capability, the use of signal redrivers at the system
level may be required to guarantee SATA 6 Gbit/s operation. The SBC346ARTM includes redrivers on the
SATA ports.
A single LED (
) on the rear of the printed wiring board (PWB) shows
activity on any of the SATA ports.
