October 20, 201015 yr All the hardware is in place except for some of the the hard drives. I have done this round of testing with only 5 drives. Eventually this will be a 16 drives system (1 parity, 1 cache, 14 data). Key Features: 1. Intel® Xeon® 3000 Sequence and Core™ 2 Quad / Duo Series in LGA775 Package (FSB 1333/1066/800 MHz) 2. Intel® 3210 + ICH9R Chipset 3. Up to 8GB unbuffered ECC / non-ECC DDR2 800/667 SDRAM 4. Intel® 82573V + Intel® 82573L PCI-E Gigabit Controllers 5. Built-in SATA ICH9R Controller 6x SATA (3 Gbps) Drive with RAID 0, 1, 5, 10 Support 6. 1 (x8) PCI-Express, 1 (x4) PCI-Express, 2 64 bit 133MHz PCI-X, 2 64 bit 100MHz PCI-X 7. On board ATI ES1000 32MB Graphics 8.

I plan to use a faster drive for parity than the WD 1TB Green I used for this test. Hopefully that will improve speed a bit. Luca Hi Luca, what SATA controllers do ypu have installed additionally to the built in controlers of the board? Cheers Chris
October 20, 201015 yr * Parity hard drive: WD 1.0TB Green (WD10EADS) <- used only for some of the tests * Cache drive: none * Data drives: x3 WD 1TB Green (WD10EADS), x1 WD 1.5TB Green (WD15EADS)Luca Hi Luca, what SATA controllers do ypu have installed additionally to the built in controlers of the board? Cheers Chris Part of the issue is the use of green 5400RPM drives. That's about what I had on other motherboads with a WD Green drive for parity and data. Switching to a 1.5TB Seagate 7200RPM 32MB cache drive for partiy and using the same for my most critical small fileserver storage beefed it up a great deal. Tweaking to the unRAID MD driver brought it even higher. With latest unRAID I was getting 30MB/s with the seagate drives for parity and important data. I would get from 22 to 30 for the 1TB WD drives. but they are EACS 16MB drives. After a bunch of tweaking I get from 30-50MB/s on bursts. But I have 8GB and a number of tweaks to the kernel and MD driver.

Cheers Chris Your answer to this is in Luca's signature "2xAOC-SAT2-MV8" it is the SuperMicro AOC-SAT2-MV8 the same cards I have in my X7SBE. Yup that is correct, two AOC-SAT2-MV8, old school. I just replaced the drive cages on both servers with Norco SS-400 (I was tired of taking everything apart just to replace a drive). Great motherboard (and controllers), no complaints.
