    Fun Build aka StorageRipper

    The transfers are very unsystematic, sometimes a week of intensive downloads, then several months of working with only locally available data. It is research, so one does not know at the beginning what (and if) will be found and what to do next. The connection is just a gigabit network, 110MB/s...

    Fun Build aka StorageRipper

    A few weeks ago I have added some modifications to the original system (see also the first post updated with green). Original fan F1 cooling the raid controller was older Noctua model NF-P12. I replaced it with not quite standard NF-S12A PWM. This modification of their mainstream 120mm model...

    Fun Build aka StorageRipper

    Well, this is totally consistent with my numbers from the first post: ~160W idle with SSD array (~5W per disk), ~310W under IO load (~9.5W per disk, +100% relative to idle or -50% relative to IO load). I use single port mode; under dual-port mode write load will be more intensive, and according...

    WEPYC ThreadRipper build: FATbild

    While planning my build I also worried about those two fans. Later, during system testing I removed top grills (both naked fans can be seen in pictures) and tried to stop each of them with finger. Literally, no difference in system noise while they rotate or stopped. From my personal experience...

    Fun Build aka StorageRipper

    After few days of testing everything was fine until I started to experience rapid full system shutdowns within the first second of a copy operation or starting IO benchmark. Switching from Win to Linux did not change the situation. It appears that I localized the issue: originally I was powering...

    Fun Build aka StorageRipper

    In theory, yes but in practice fan F1 needs to be moved somewhere most likely, and probably some other cooling solution for both controllers needs to be implemented. Also, 2nd controller can be installed vertically, next to supercapacitor. Or GPU moved to vertical position, replaced by 2nd...

    Fun Build aka StorageRipper

    Some benchmarks. Done using fio-3.30-51-gb5f3 under ubuntu 20.04.4 LTS with ext4 file system. Kernel was upgraded to some 5.8.18-050818-lowlatency, otherwise in several tests maximum of 300k IOPs were obtained instead of 2M. Fixed fio flags for all tests: --ioengine=io_uring --iodepth=32...
