    Supermicro X9DRi-LN4F+ error beep codes

    I am troubleshooting one of these at the moment - built the new cluster, was fine for 48h then slowed to 5% of performance and won't reboot (B2 POST code - and now, after 8h off, BA). Can you get to the BMC to see the POST Snooping page? Does it power itself off after the beeping? CPU known...

    Trusted Sources - Mellanox ConnectX-3

    I'm only looking for 3-4 - replace the flaky one and add a pair to the lab NAS. It's not a production/commercial environment by any means, hence the choice of AUD50 second hand not AUD500 vendor new :). And while I don't mind if this turns into a "who has what interesting stuff" thread, @Patrick...

    Trusted Sources - Mellanox ConnectX-3

    Thanks - yeah that's a good point. I'm in Australia but I recognise most of this stuff is in the US and Europe.

    Trusted Sources - Mellanox ConnectX-3

    I'm looking for a source for Mellanox 3 (pref. the MCX311A) cards - every source I find on Ebay seems to have the same set of images and text for the MCX311A cards; I've had two failures (one never detected, the other connects but doesn't pass traffic) so I'm left wondering if the cards are...

    2nd Domain Controller, or vMotion / HA

    From a "doing it the right way" perspective, you should have 2 DCs with appropriate rules (DRS for VMware I think) that schedule them on separate hosts.

    X10SRA + E5-1650v3 + ECC UDIMMs - POST code 67

    SuperMicro reckon it's a bad socket. I need to get off my ass, find a CPU socket cover and complete the RMA.

    X10SRA + E5-1650v3 + ECC UDIMMs - POST code 67

    Honestly for $100 or so, this is worth a bid anyway https://www.ebay.com.au/itm/174153454315 It's not the RAM. Plugged in some loaner RDIMMs from a working Precision T5810 (it's the same platform and CPU) and same error code. Will switch CPUs next... Edit: OK and it's not the CPU either...

    X10SRA + E5-1650v3 + ECC UDIMMs - POST code 67

    DDR4 ECC, but unbuffered, not registered. It's the first thing I'll swap out with stuff from the Precision because it's easy and I'm lazy (swapping the CPU is annoying and slow), and I'm _technically_ unsupported (which could mean "if it works fine, but if it screws up you're on your own" or...

    X10SRA + E5-1650v3 + ECC UDIMMs - POST code 67

    No it's been built for at least 2 years if not longer. The board is E-Bay new (this stuff is not really available new, or at reasonable prices in AU). I may grab a spare Precision with the same CPU from a mate and see if I can component-swap to identify. Thanks anyway though it's very much...

    X10SRA + E5-1650v3 + ECC UDIMMs - POST code 67

    No, as far as I know it's a legitimate production E5, not an ES. There's no graphics on board - I'm not sure I'd expect it to post without, but it's easy enough to try. I'm in AU on the Central Coast of NSW, so far away from everyone :D Edit: Nope. Same code without GPU, without a keyboard...

    X10SRA + E5-1650v3 + ECC UDIMMs - POST code 67

    Trying to track down why my replacement board, an X10SRA, won't complete POST with a CPU and RAM that used to be fine. The previous board was an Asrock X99WS which underwent some form of rapid decompressive failure - something went bang and I can't see which component failed, though I expect...

    Hyper-V Server Build Questions

    I agree that 128GB is ridiculous, but that's why I said 24 will suffice. Note that Exchange 2013 and 2016 generally want 8GB just to start services, and 10GB is a more reasonable minimum even for 5-ish users. 4GB for an Edge isn't viable for more than a lab. Also, 2019 has a different...

    $79.75: 960GB Micron 5100 Pro

    Too good to pass up. Heck, it's getting close to the point where it'd be possible to switch from hybrid rust to flash for my lab...

    EU ebay: Supermicro X10SLE-F (Micro-Cloud node) usually under 10 Euro

    Nothing in the "HardwareLager" store either that matches this?

    Hyper-V Server Build Questions

    Honestly dude if you're trying to do the right thing for the business you need to set your personal feelings aside on some of what you've said. SBS is dead. I know a dead OS when I see one, and I'm looking at one right now. That OS is definitely deceased. The only reason it's still upright is...
