Re: The Octane Hardware Aggregator

... And now I feel compelled to recreate by myself the whole Industrial Age! Damn! :D Hmm, any chance you could replace the under-maintained infrastructure of, oh, pretty much every country? :D And the island where my step-Dad lives could do with a bridge there, the 22km ferry journey is annoying, ...

Re: The Octane Hardware Aggregator

It's a strange thing how events can shove one sideways into something else... just glad to hear you and your family survived the fire!!

Fat? I am not sitting here with a mug of choccy milk! Oh dammit... :}

This year will be 30 years since I first went to uni, which my brain insists is completely ridiculous. Certified old git.

Re: Indy or O2 for hostile-heat environment

... I suspect that some CPUs may be more picky about voltage, and a PSU that's in-spec, but barely, used with one of those CPUs, may result in noticeable flakiness. ... That sounds very plausible. It might be one of the issues which the various mbd revisions, PROM updates and PSU changes sought to ...

Re: Indy or O2 for hostile-heat environment

The Sirix networking is called Selan. I've been working with such users for a long time, many do have O2s, usually running 6.3. Ask Stoll about IRIX maintenance, they tell customers to contact me. I've done work directly for Stoll on a number of occasions. {Content pertaining to trolling incident re...

Re: Indy or O2 for hostile-heat environment

True, ChallengeS is reliable (I ran one for 5 years at a uni and it never crashed once; the NT server would crash sometimes as often as a dozen times a day), but it still has the issue of a costly PSU to replace. Also of course, it only has 10Mbit (at least O2 has 10/100, though the o.p. hasn't said...

Re: Indy or O2 for hostile-heat environment

Whatever you might believe , O2 is the only COTS computer ever approved for use in space, though it likely used an industrial chassis rather than the usual one (same kind used for some medical systems). Robust it certainly was. O2s are still widely used in industry today, across a vast spectrum of t...

Re: Indy or O2 for hostile-heat environment

Good point! Btw, some have said 6.5.30 has issues on O2; can't say I've ever noticed this (except for the ChangeSysID prog not working), but someone mentioned it to me the other day. uunix, do you know what issues people are referring to with 6.5.30 on O2? Though of course, one can use earlier versi...

Re: Indy or O2 for hostile-heat environment

Heh, I understand, but honestly I've seen a near equal number of abberant Indys over the years. :D

Thing is though, as I say, repairing an O2 is a lot cheaper should that ever be required.

Re: Indy or O2 for hostile-heat environment

There's a reason NASA chose an O2 for going into space. ;) I've dealt with both for a long time, I'd go with O2, and it uses less power than Indy (though to be fair my table of results is for an XZ system, should really fire up an XL8, see what it does, and with the XL8 removed, though one could the...

Re: Indy or O2 for hostile-heat environment

Yes, R5K should run cooler in O2, and if performance is not important then what you could do to reduce power consumption a little more is fit the R5000PC/180 which has no L2 (or for Indy, the R5000PC/150). Mind you, an R10K/R12K doesn't use as much as many might assume. See my example data here: htt...

Re: how things should be shipped properly

Close call! Sometimes though the world is just weird. I once received in O2 posted inside a cubic box that wasn't even as big as the O2, the lid flaps bulged upwards and there was no padding of any kind. The unit arrived completely intact, not a scratch on it. In honour of this ridiculously unlikely...
