No backplane - leave sgpio not connected ?

[idata]

Hi,

I'm using RS2WC040 raid controller connected to S1200BTL motherboard.

I connected 3 SATA drives using SFF-8087 mini-SAS cable - directly no backplane.

(SFF-8087 cable breaks to 4xSATA + 1xSGPIO)

My question:

I'm not using backlane so I shoud leave SGPIO cable unconnected - or connect it to S1200BTL motherboard sgpio header ?

thanks,

Vilius

Leave it unconnected.

vilius,

Wikipedia has a good http://en.wikipedia.org/wiki/SGPIO article on SGPIO. There is says SGPIO is an acronym for Serial General Purpose Input/Output which is a 4-signal bus used between a host bus adapter (HBA) and a backplane.

Since yiou have no backplane, as Edward said, leave it unconnected.

Regards,

John
