    I finally tackled the side panel having actually bought the 4.5" hole saw required to create the cut outs for the fans. Not the easiest job but they seem to have come out ok. There are a couple of marks to the black finish, but nothing too obvious. Fans fitted with silverstone filters New...

    Very useful info there, thank you. I actually managed to source the second solid side panel direct from corsair this week. I will be modifying it to fit a pair of 120mm fans to provide the airflow across the expansion cards. Good as that bracket would be, it would still benefit from some...

    I bought some Arctic P14's to replace the old scythe kama flow 120mms as the case has provision for the same number of 140mm fans as 120mm so it makes sense to use the larger diameter. I swapped the front intakes out as well as the top exhaust. They seem to shift a hefty quantity of air at...

    Case Recommendations? Lots of 3.5 / 2.5 bays

    I originally wanted a server case like a Norco but backplane failures are what put me off more than cost. The drive cages for the 750D seem to mount in quite well on the right side as they anchor both at the top and bottom. The ones on the left don't have any anchor at the top so there is some...

    Case Recommendations? Lots of 3.5 / 2.5 bays

    The Corsair Obsidian 750D can fit 18x 3.5 drives with the additional cages leaving 4x 2.5" sleds and 3x 5.25" bays available. Fitting the additional drive bays beyond 12 drives does depend on your motherboard and expansion card configuration. I went this route to avoid using backplanes after...

    On to the case swap. The 750D is quite a bit bigger than the CM690. I put a new 8TB drive in already as that is going to be used as an rsync disk for certain files from the main array. Deconstructing the 690 was simple enough but the last 6 years in the loft haven't been kind. That green cloth...

    Raid controller alarm went off last month. Looking at it, a disk had possibly died as it had simply disappeared. I ordered two 2TB ultrastars to replace the dead drive and provide a hot spare. Can't moan too much as it's been running pretty much 24/7 for nearly 6 years I discovered when...

    Bought some new fans for the juniper switch to try and quieten it down a bit without triggering a fan failure warning. 2x 40x40x28mm 12,500rpm San Ace 109P0412J3013 fans instead of 18,000rpm. Idle fan voltage is 4.5V so something like a noctua that maxes out at 5000rpm would run too slow at...

    Dell 0H092P Quad Port Nic - computer won't boot

    Have you tried covering the smbus pins on the pcie connector with tape? (Like this) May or may not work, but certainly worth trying.

    How to Identify Exact Solarflare model?

    That would be a dell OEM version of a SFN-8522. Precisely which version is very hard to determine.

    I bought some OM3 fibres from FS along with some LC-LC links for the wall boxes I got from RS a few months back. Wall boxes should be pretty resilient as the fibres will enter at the base of the boxes keeping the connection virtually flush with the wall to avoid breaking them. Since I now have...

    10Gbe poor performance in windows

    Just pushed the 1903 update on my threadripper machine and iperf performance is now fixed on this machine. Across 5 instances I saw just shy of 40Gbit/s and a single instance gave just over 16Gbit/s. I'll look into doing the X79 system tomorrow and see if it also sees the same improvement.

    10Gbe poor performance in windows

    In respect of the pcie link width issue I spotted, I've now fixed it by swapping the NIC and audio interface around as both were in 8x slots. GetNetAdapterHardwareInfo reports the correct link width and speed now but it didn't make 1 iota of difference to the throughput though. Something I've...

    10Gbe poor performance in windows

    What baffles me is that windows itself isn't necessarily the issue as I've seen plenty of other people have no issues achieving near 10 gigabits/s transfers using windows 10 with similar or even older hardware. The performance I'm seeing on my threadripper system isn't actually too bad but it's...

    10Gbe poor performance in windows

    Run the same test on a live boot of fedora 30 and all is well. Definitely seems to be a windows issue.
