SuperMicro BPN-SAS-846TQ 24P 24D Backplane | eBay

No metal frame.

They have another bunch for €40 OBO, same pics, no discernible difference besides "24P 24D" in the title of the cheaper ones.

Amazing find for those in EU. I've never seen it this low here.

Price went up to €29.99. Does eBay do this automatically if it's "more likely get sales" than in the past or something?

EDIT: both seem to be the rev 3.1 TQ models so a wild guess is that it's just a trick to make more money out of it.
Anyway, i'm not gonna touch this since there will be a cable hell using these instead of 846A which i have in mine 846 chassis.
I have TQ in my 826, i feel it blocks part of air path from disks to the fans.

Hm interesting - can't imagine they did that manually on a Sunday.

And o/c, -A is better than TQ but thats preferable to a SAS1 model.
I think of this as a cheap way to upgrade a SAS1 model, 20 (30) bucks + a newer PDB maybe and u are all set vs a much more expensively sold -A/-SAS2.
Also - while the many cables are messy - you can individually assign drive slots to cards/onboard sata ports which you can't with SAS2 and only in blocks of 4 on -A.

Agree with your points. The last point is a good one really. I'm planning how to connect one of the 846A to the disks and i figured it out quickly, it's not that easy, since it's 4 x 6 ports.
Will a SAS2 breakout cable work without issues in "reverse" order? I.e 4 SATA ports on MB on one side and a mini SAS2 connector to the backplane.
I think i have enough HBA ports, but just wondering

Works fine i did the same on my A Backplanes to use the Onboard SATA Ports.

The buyer raised his price to 39.99 euro, I still bought one.
6 left, better hurry!

Above points are valid, this is obviously not as good as getting a SAS2 backplane, but at the usual price of around 500 euro (not even counting shipping from the US and taxes on top of that), this is at least a half decent "upgrade".

Gotta find me some good quality long breakout cables for these now, anyone got a cheap link for those?
Also, what is a good HBA for these that will run in IT mode for freenas?
LSI 9211-8i is nice but can only connect 8 HD's, don't have 3 PCI slots free.

If you want to connect THIS Backplane (TQ) to a HBA you do not need the Reverse breakout cable!

So just look for a SFF-8087 to SATA.

Keep the LSI 9211-8i and get yourself an expander, e.g. the ridiculously cheap HP 24-bay 6G expander.

oooh nice, good tip Kybber!
now to find a pcb that I can mount in my case so this does not take up a PCI slot

edit: expander is only 3G
edit2: Intel RES2SV240 is the one we want, only 20 ports but w/e, everyone has at least 6 sata ports on their mobo anyway

Be aware that the HP only does SAS 6Gb/s and SATA 3Gbs/ - if I read the other threads correctly

 

[I_D]

Yup, I saw that too, bummer, but the Intel RES2SV240 does 6G, albeit with "only" 20 ports.

 

[Kybber]

Sorry about that. I only have SAS drives, so not bitten by the 3G limitation. Perhaps you can single-link the RES2SV240 for 20 ports and complete with the remaining 4 ports directly from your 9211-8i?
