Older, but good value at $299 shipped. I have purchased from Garland Computers before and had a good experience.

That backplane - is it SAS2 ?
It is the BPN-SAS826A backplane. The A denotes that there is no expander; simply 3x SFF8087. If you have a SAS2 controller, it will communicate with the drives at SAS2 / SATA III speeds without issue. Pretty sure SAS3 will work as well!

Do note that, unlike the expander backplanes, you cannot simply use just one SFF8087 cable, you have to use all of them if you populate all the drive bays.

Thanks for the info Rain.
I suppose this would mean needing to used 2 m1015's to enable all 12 bays - correct ?
Would it be possible to just plug into the motherboard ?
I'm looking for a 12-bay server for freenas testing. I'd also like to use SSD's, so having SAS2/SATA 3 connectivity would be great.

I'd suggest multiple HBA's such as the M1015 but there's nothing stopping you from using the built in SATA connectors.
I have the 16 bay version of this and have 14 of the bays controlled via 2x Dell H200 with two ports unplugged and, instead, plugged into SATA on the motherboard. Did this as OmniOS doesn't like booting off of the HBA but has no issue with the onboard SATA.

Either way works, just as @manxam pointed out. Two M1015s would work fine, or just one M1015 and a SFF8087 reverse breakout cable from the backplane to four SAS/SATA ports on the motherboard. A forward SFF8087 breakout cable will not work, despite seemingly being exactly the same.

Because I was curious myself as to WHY one needed "forward" vs "reverse" breakout cables I did a little research:

Forward Breakout (think ethernet crossover cable) :
Host/controller:
Transmit pair on pins 2 & 3
Receive pair on pins 5 & 6
Disk:
Receive pair on pins 2 & 3
Transmit pair on pins 5 & 6

Reverse Breakout (1:1):
1:1 pin mapping between each 4x SATA connector and the 1x SAS connector

A = sff8087 connectors, 1 per 4 drives, TQ is standard sata data cable connectors, breakout cables are necessary here.

Ahh thanks... I was going back and forth between the manuals and couldn't figure out the difference. Can't believe I missed that.
