SC-846TQ - Average or typical?

[Nasphreak]

Maybe it's typical, but $212 + S&H gets all of the following:

Chassis: Supermicro SC-846TQ-R900 (SC-846TQ-R900 -??- hopefully pieced together right)
Backplane: SAS846TQ rev. 3.1 (individual ports)
Motherboard: H8DME-2 2.01A
Processor: 1X Quad-Core AMD Opteron 1.8GHz 2346 HE
RAM: Samsung 16GB 8x2GB (PC2-5300P? - per photo)
RAM Total/Open Slots: 16 Total; 8 Open
Power Supplies: 2 x 900 W
HD Controller: 3x Supermicro SAT2-MV8
IPMI: SIM1U+ with AOC-USB2RJ45

I was actually just looking at this. I have my own SuperMicro X9DRD-EF-B, Dual E2670s and 64GB of RAM to cram in it. But I have a question that I can't seem to find the answer to anywhere

Does the 846TQ Backplane support larger than 2TB Drivers since its direct connect(I know the SAS-846ELi will only recognize 12 drives or so if they are bigger than 2TB). And will it support the faster speeds since its direct connect? Like will my 6Gb/s SATA Drives work at their full capacity in the bays? Or will it be limited to 3Gb/s?

I'm looking to eventually run 4 RAID6 Arrays of 6 Drives Each of 6TB or 8TB Drives (I will build one array at a time over the next year or so.

Thanks for your help!

TQ backplanes definitely support devices larger than 2 TB since it's basically a pass through backplane. However I'm not sure if the transfer rate is limited to the HBA or the backplane, I'd guess the former.

Yes, the 846TQ backplane supports >2TB drives at SATA3 link speed

The TQ backplane is good and bad, it's a blind pass-through so whatever speeds you want to run should be fine but you won't get any dual-porting functionality like you can with the SAS backplanes and you'll need a bunch of breakout cables to wire up the mess.

I appreciate the quick replies!

I have bought this chassis and yeah, I know the downside is the individual wires because I will need 6x 1m 30AWG Internal Mini SAS 36pin (SFF-8087) Male w/ Latch to SATA 7pin Female (x4) Forward Breakout Cable - Black - Monoprice.com of those to fully populate it.

So yeah, at first I certainly don't mind the wiring, considering It won't be fully populated, and maybe down the road I will change over to a SAS2 backplane, but after dropping Approx. $1,000 on all the various parts (still need to spend a tad bit more) the Extra $180 or so for the SAS2 Backplane doesn't seem worth it right now if I can work with out it!

So yet again! Thanks everyone.
