So as items come in, I have a few cable questions ;S

Controllers:
- IBM M5210 12Gb/s HBA [2x SFF8643]
- PCI x8 slot
- Intel RES3TV360 36port 12Gb/s RAID Expander Card [8x SFF8643]
- Mounted on 3 rubbers + 1 MB screw, power by Molex
- X10DRL-i onboard 6Gb/s [10x Sata]
- Front: BPN-SAS-846A | 24 drives | 6 SF8087
- Back: BPN-SAS-846A | 12 drives | 3 SF8087
Issue/Question:
- The backplane manual says it drives 4 drives per SF8087 connection, with numbers - thus it matters where I plug in the SF8087. Currently I run two SF8087 - SF8087 from the backplane to the frontplane, as the front plane doesn't list the connections to be drive specific. Figured if I give the frontplane enough bandwidth, it will share it with the backplane?
- I connected two SF8087 -> Sata Breakouts to the 2 x 4 internal ports of my motherboard (but that provides 6Gb/s - fine for my slower drives). Should I connect those sata breakouts to the backplane, where it can take specific drives in each slot to ensure i have the slow disks on that lane? or does it figure that out automatically?
- The M5210 should be connected with 2x SFF8643 to the Intel Expander, which than connects to my back/front planes?
- Any other advice? I'm a bit PCI limited.. as I have two P3700's on the way & one of the ram slots blocks a lot..
- So I need 7x SFF-8087 to Mini-SAS (SFF8643) and 2x SFF-8087 to sata breakout and 1x SFF8643 to SFF8643 to connect HBA to Expander and 2x Mini-SAS to QSFP+ to connect to the 4U 60Bay ( 1 to HBA, 1 to expander) [<Most important question]
- or (without 4U 60bay) ->
- 2x SFF8643 HBA -> Expander, and 7x SFF8643 -> 8087 and 2x Sata breakout
