    Rackable System 3U 16 drives chassis SAS2 upgrade

    You really shouldn't be having to move this thing.. I don't think the weight should be a factor. It should be a case of getting it working, then bring it up and install it upstairs. You should remove all the drives while moving it anyway - and that will cut down the weight by a lot. You...

    New rig: SSD vs spinning RAID10: Please help.

    Valnar - just wondering why you're suggesting MLC vs TLC? I thought endurance on recent devices (eg: 850 evo) was high enough now that it basically is not a factor unless you are doing things like video editing?

    Ok, weird situation. Please read and advise.

    Are the drives in RAID or something or all individual drives?

    Sanity check - performance bottleneck with Xeon CPU on ZFS SSD pool

    Hey guys - thanks for all the responses btw. So I think what may be happening is this is just a limit of how fast Bonnie++ can generate it's data - maybe because it is only a 1.8GHz clock. That also explains the 25% CPU.. because only one core is maxing out and Bonnie must be single...

    Sanity check - performance bottleneck with Xeon CPU on ZFS SSD pool

    I had updated sd.conf on my install so that it knows about the 840 Pro and is already creating the zpool's with ashift 13. Just to clarify what you mean by wasted space though - the ashift doesn't represent a minimum file size does it? eg: It means every file uses up a minimum of 8K...

    Sanity check - performance bottleneck with Xeon CPU on ZFS SSD pool

    Cool - Thanks! I haven't enabled compression yet as I wanted to test raw first.

    Sanity check - performance bottleneck with Xeon CPU on ZFS SSD pool

    Wow - thanks for the tip omniscence! Maybe bonnie++ is what is at fault.. I just got fio installed and ran it and got much better results: /opt/csw/bin/fio --name=writebw --filename=/Test1/bm/writetest --size=250g --direct=0 --end_fsync=1 --rw=write --bs=1m --iodepth=32 writebw: (g=0)...

    Sanity check - performance bottleneck with Xeon CPU on ZFS SSD pool

    Thanks for the reply Omniscence. I've fixed up the tags - hopefully easier to read now. For the zpool's - for the stripe only tests I just created them with: zpool create Testpool <drive1> <drive2> <drive3>.. zfs set atime=off Testpool zfs create Testpool/bm For the single drives it was...

    Sanity check - performance bottleneck with Xeon CPU on ZFS SSD pool

    Hi guys, I've been trying to figure out if my CPU really is my bottleneck here... hopefully someone with some experience can weigh in or point out what I am missing. I am setting up a new ZFS storage box. Basic specs: Supermicro 16x 2.5" bay chassis - CSE-213A-R740WB Memory - 64gb CPU - 1x...

    LSI 9211 hates SSDs?

    Wow - I'm glad I came across this... I just finished setting up a new storage box and had flashed it to latest (P20) and was just getting ready for testing... I would have seen crappy performance but would have assumed it was something else rather than the controller firmware.. PigLover - do...

    So I snatched a CSE-846BA-R920B for $580 from Amazon

    Wow lucky you.. I woulda bought one instantly too. Definitely a typo I'd say..

    *Official* Norco data storage products thread

    Hey - I think it's great that you are labeling them like this. What I would do instead is decrease the font size on the labels so it is like 1/4 that size.. eg: put 4x labels on one that size and then cut them down. You don't need to be able to read the serial from the other side of the...
