    Benchmarking SSDs - what tools do you use?

    When benchmarking SSDs you want to precondition the NAND in order to reach a steady state. The precondition workload will have an impact to following performance. This is heavily dependent on how the SSD architecture is setup, but typically for a random workload benchmark you want to...

    [eBay] - Supermicro A2SDi-4C-HLN4F - $100 (offer accepted)

    Nice board, keep in mind the PCIe 4x slot is shared with 4 of the SATA ports.. so either you can have: 8 SATA + no pcie 6 SATA + 2x pcie 4 SATA + 4x pcie For $100 that is a deal.

    Long Generic Test Fail (Seatools), can it be fixed by "fix all long?"

    By "fixing" the failures the write is remapping the bad sectors to spares. Assuming when you write the same area you don't get more failed sectors the problem should be taken care of. I'd run your own burn in test with badblocks. Do the default "destructive" write/read test, which does...

    How common are bad SATA cables?

    I've ran into a number of bad cables. If you see any dma or bus errors, that is typically due to the cable.

    Looking for replacement of power hungry MD1000

    Consolidate to a set of mirrored 10TB drives and ditch the DAS. I'd also replace the X8SIL-F/L3426 as more modern hardware will be much more power efficient. X10/E3-12xx v3 is a good middle ground for cost/power efficiency.

    Forced Unit Access, plp

    In my experience, yes. The enterprise SSDs I've worked on all consider the write complete and safe once it hits the cache. A write with FUA set will return complete at that time. Rotational media is a different story... not enough time/power to flush the write cache on power loss, so FUA in...

    Supermicro X10SL7-F $63

    No gotchyas really... just update the SAS, BIOS and BMC firmwares to the latest. Also, this board will only take unbuffered ecc memory.. so keep that in mind. ECC udimms carry a bit of a premium and are harder to come by. Non-ecc udimms or rdimms won't work.

    512 vs 4k - why convert?

    4k is now the native sector size on most storage devices. I'm sure there are many reasons, but this is a big one... operating on 512b boundaries allows for sub-optimal alignments which can hurt performance causing rmw on unaligned sector writes. This is especially true for SSDs.
