Just bought 12 new 8-core 24GB nodes… for $2700

Friday, April 19th, 2013

I just got three of these.
They’re a bit old, but benchmarks put that processor at about half as fast as an FX-8350… and there are two of them per node, and 24GB of RAM each, and they’re Dell servers, so they won’t break all the time, and the whole thing will only take up 6U, and then I can ditch all of Rack2 to make space for them… win win win and better price/performance than gutting and rebuilding the Rack 1 nodes all the time. Cool! I hope this works out for everyone. I think it will.

compute-1-18 randomly rebooting

perhaps power supply – can’t remember if that’s the one I replaced the power supply in, or the one that still has the crappy Athena Power one that came with the case. Probably won’t check into it today – will wait until Monday, most likely.

Fly crashed again

Friday, April 12th, 2013

Identical symptoms. Again, hostname was fly.hampshire.edu on restart, again it wouldn’t mount /helga. Had to manually mount /helga, set hostname to fly.local, tentakel restart rpcidmapd (and also on the head node), then start tractor-engine (which wouldn’t start because /helga wasn’t mounted). But the real question is: why is it crashing? Do we need new hardware? I should run some tests…. I’m afraid it will go down again this weekend. However, I have to run to manager training….

Upgraded compute-1-2

…with compute-1-12’s old internals, since I replaced them, thinking it was mobo/cpu/ram when really it was the hard drive. Heh.

On second thought, apparently one of the sticks of RAM has gone bad in the meantime, so 1-2 will have 6GB of RAM until the RMA comes back….

compute-1-14 needs new hard drive

Guess that old 20GB unit from Josh Crawford finally bit the dust, along with a few others. They all seem to be dying around now. Good life – 12 years – they were manufactured in 2001. I’d say they don’t owe us anything, especially since they were free to begin with 🙂

Flashing caps lock and Scroll lock, no signal to VGA… nothing weird in the nagios graphs to indicate why
