SGI: hinv

This is the machine from my signature. Not sure if someone tried this yet. Took me a few years to get all equipment together (incl. the required CrayLink/XIO cables, which maybe was the hardest part of it). I've anonymized the barcodes as I don't want to disclose the original owners. Below you'll also find some pictures of it (although some hardware from the top GIGAchannel cabinet was (re)moved before getting the `hinv -vm` output). The front skins are more or less intact (if I don't touch them), the top GIGAchannel cabinet originally was a floor-stand version, hence it's missing the sides of the front skins.

hinv -vm

now this is cool ! I never seen this kind of config before.

Thanks! I like to call it the Uber-Origin200. From the manual it looks like this configuration was even supported by Silicon Graphics.

From https://techpubs.jurassic.nl/manuals/hdwr/admin/Origin200_OG/sgi_html/ch01.html#id45823 :

[...]
The configurations of an Origin200 GIGAchannel server are as follows:
* Origin200 GIGAchannel CPU module (either a master or slave module) connected to a GIGAchannel expansion cabinet
* Origin200 GIGAchannel master and slave module each connected to their own GIGAchannel expansion cabinets (one GIGAchannel per module)
* Origin200 GIGAchannel in loopback mode (no GIGAchannel expansion cabinet)
[...]

I haven't done anything useful with it yet though. I wonder if OpenBSD will be able to use all expansion cabinets.

Maximum Origin 200, nice! You may have the largest number of intact O200 front doors anywhere.

Any idea of the total current draw when all four units are up and running?

Oh, and also -- Welcome to nekochan!

Yeah, it's a real pity that the plastics on this machine are so delicate.

According to the PDU* it's hooked up to, it draws:

• 4.2 A at maximum
• about 3.7 A to 3.8 A when starting/running the firmware
• and between 3.8 A and 4.1 A when starting/running IRIX.

Voltage should be 230 V, so between ca. 850 W and 970 W (with all hardware from the `hinv` output). So not that much actually, compared to the size of the whole machine.

*) The PDU is a Cyclades AlterPath PM10i, not sure how exact its current sensor is. So maybe I'll meter it with another gauge to get a second opinion.

And thanks for the warm welcome to nekochan! Glad to be here finally!

Funny I didn't see this when you first posted it, this is a wickedly badass system you've put together!

Have you come up with any nice uses for it? If nothing else it would make a nice Mental Ray render node. Uh, you're not really running OpenBSD on it though, are you?

wow nice system!

were these GIGAchannels the ones where there was a way to put in an Octane Impact graphics card?

Yes, although you have to modify an SI/SE GFX card by replacing the latch mechanism, which you can salvage from e.g. a MSCSI option card.

That is the most unbroken O200s I have ever seen in one place. Awesome setup and well done!

Thanks guys! I believe I was just lucky to get all pieces together and intact.

I was afraid, someone would ask. Actually it's currently waiting for the next start up . I have mainly played with my other machines since my last post to this thread. It would be interesting to know, how many external graphics modules can be used with this machine (like with bjornl's Onyx 200 ).

vishnu wrote: Uh, you're not really running OpenBSD on it though, are you?

Actually I don't remember if I ever started OpenBSD on the whole machine, I know that it works on my first O200 (a single node, which originally came with the GIGAchannel expansion cabinet that's now on the top of the machine this thread is about). On http://www.openbsd.org/sgi.html it reads that MP operation is only supported on single-node IP27 machines. So it might not work at all on a craylinked O200. But I should check. On the other hand it might run on the machine if its partitioned into two systems, although that's not that useful (first craylink two machines, then partition into two machines).

EDIT:
Last paragraph moved to new thread .

I still haven't tried to fire up my o200 yet. It was new in box. No plastics or door.

The guy who sold it to me was a 3rd party dev for SGI products. They used it to test some things and it was turned on and used very little then put right back in the box.

I have the o200 in practically brand new condition except for the fact that it is now dusty.

I have yet to fire it up. My goal was to have it utilized by the O2 as a render node. I used to run Maya and Lightwave like this on PCs using the PCs on the network to run as render nodes. Never set up an SGI this way or even know where to start.
