We are going to build out a couple free nas boxes and would like to get some feed back on some questions from the community before we spend money on the disks.

here is the equipment so far

Case: Supermicro Superchassis SC836E26-R1200B
Motherboard: Supermicro X8DT3-F
CPU: Dual Intel 6 Cores X5650 2.66Ghz (12M Cache, 2.66 GHz, 6.40 GT)
RAM: 48GB DDR3 ECC REG Memory
Hard Drives: 16x 3.5" Caddy for hard drives (we have not decided on 2TB or 3TB drives yet)
RAID: On Board LSI SAS1068E
RAID: LSI SAS 9211-8i card
IPMI
BackPlane: SAS2-836EL2 with two LSI SAS2X28 expander chip
SAS2 dual Expander Backplane, features:
• Scalability through cascading
• 6Gb SAS2/SATA3 HDD support
• Inband SES-2 Enclosure Management
• Redundancy support through SAS drive only
• Single input/output SFF 8087 connectors

So our questions are:
1. Is there any firmware update that will support 3TB on the SAS1068E?

2. if we use the 9211-8i does anyone know if its just a single cable we need to use all 16 drives or is there special cable we need or what? i currently only tested a single drive in the unit and it appears to find the drive in any bay i put it in. I'm confused if i put more than 4 disks in will it or will it not see all the drives with single cable.

thanks in advance for your help.

The backplane has two SAS expanders in it. One SFF-8087 is sufficient to access all 16 drives.
