Dear Edward.. your answer is very helpful.. now i'm serching for backplane..
the backplanes of intel.... at this pdf says that
AXX6DRV3GEXP or AXX4DRV3GEXP
No Fault LED control cable needed.
Note: Intel® RAID Controllers SRCSATAWB offers expander backplane support.
AXX6DRV3G or AXX4DRV3G
RAID card connector: J6, white
Backplane connector: SES, white
Cable: 3-pin SES
Note: RAID FW 420 or higher is required.
which of these is the best solution for me to choose??
please remember that my controller has 8x2 fault drive pins.
Both will work with your controller. If you use a expander backplane, you don't need any cable besides the SAS data cable. If you use a non-expander backplane, you'll need to connect the 3-pin SES cable for the drive fault LED to work properly. I believe the cable comes with the backplane. The 8x2 fault drive pins are not used with Intel backplane.
That 8x2 pins connector gives you 8 fault LED signals - one LED per drive. Meaning if you connect the HDD activity LED to two pins for drive 1, and then your drive 2 fails, the LED won't start blinking. LED behavior is documented in TPS section 18.104.22.168. It won't be necessary if you're using an Intel backplane.
