My car is full of SGI Origin 350 parts. Looks like six compute chassis, two NumaLink chassis, an SGI RAID, and a bunch of supporting parts. It was originally assembled as two systems, but might be more interesting assembled as one large system. I need to open the chassis to see what CPUs and RAM are installed. It will probably take a lot of studying of the manuals to get this thing running.

Sounds pretty exciting. Post some pics if you can once you get things sorted out. I like that idea of one big system :cool:

I started reading the manuals. It looks like pretty complicated to get everything interconnected, powered up, and configured. I didn't get any disks with the system so my first project is to install a disk in one of the base chassis and see if I can get IRIX installed. Then I can add a single compute chassis and get that working. After that I need to connect additional chassis through the NumaLink chassis, so that gets a little more complicated. I have the L2 chassis, but I am not sure if I really need it.

I am interested in learning about it, getting it running, and not much more. Hopefully someone will offer me a reasonable amount for it once I can prove that everything works OK.

I have one of the chassis with the L1 controller powered up.
If everything works, and I can supply enough power, I could make a configuration with 24 1GHz IP35 CPUs and 24GB of RAM

IRIX 6.5.30 installed. Both IBM SCSI disks that I installed are showing errors. The CDROM had trouble reading the original SGI CDs, but works OK with CDs that I wrote.

I replaced the IBM SCSI disks with 73GB Fujitsu drives, and it fixed the disk problem. One of the chassis looks like the IP35 board is bad. It reports TLB errors if any of the CPUs are enabled. The inventory now is 2x compute chassis each with 4x 1 GHz IP35 CPUs. They can be interconnected with a NumaLink cable to make a 8x CPU system. Also 3x working and 1x broken compute chassis each with 4x 800 MHz IP35 CPUs. These can be interconnected through a NumaLink hub to make a 12x CPU system. It is possible to connect the 1GHz and the 800 MHz chassis with a NumaLink hub to make a 20x CPU system. I am not sure how well it would work having different speed CPUs. I also have a SGI InfiniteStorage FibreChannel connected chassis that holds 14x SATA/SAS drives. I have not tried this chasis yet.

Nice. Making a single system out of two might be tricky when it comes to getting the same system serial number on all nodes. No problem with mixing the different CPU speeds, IIRC.

There were various tricks to change a given brick's serial number, and this is where the L2 and/or the NUMAlink router(s) can help. I don't remember the details, they were all on the Nekochan forum and that's where I kept my notes - so they're all offline, post GDPR. Check the Nekonomicon, where a lot of the Nekochan forum content was revived as static pages.

Lots of people can help you real-time with getting that going over in the SiliconGraphicsUserGroup Discord: http://sgi.sh/ click on the microphone....

A number of users there have big o350 setups and have gone thru the pain of all the L1 and L2 configs to get it all to work as it should.
