Was 1+1G ram, added 16+16 and now have 34G. Two power supplies. 1- Never bothered to change SAS controller mode. 2- SATA disks (up to 2T of course) work perfectly, never used transposers. 3- First worked with an internal SSD (at internal SATA port, plus an addon power cable) for OS (always ZFS) + 2 SATA disks (ZFS raid) for data. 3 years, no problems. 4- Now i bought 2 SAS 1T, with OS on them, and also works fine. 5- Hot plugging disks is working fine. I actually increased capacity with bigger disks without stopping anything this way. Had 500G SATA before 1T SAS diks. I configure the 2 eths in OVS (openvswitch) bond mode, with several VLANS and internal networks (OVS IntPorts). In your case, with many SAS disks you will be fine with any configuration, e.g.: 3+3 x 2T = 6T ZFS raid, OS + data, the fastest combination, or 5+1 ZFS raidz, 10T space, with best capacity, or 4+2 ZFS raidz2, 8T space, also big, and safer. Do yourself a favour, and buy some decent SAS disks, at 7200rpm are very cheap.
