Congrats on the sgi baby.


Hey thanks man!
Once I get steady incoming flowing back in, I'll try and get the Octane running and post some pics if it.

Pretty much. But a little pocket change here and there wont hurt. I need to get a lens adapter for a camera lens first though.

Nope. More than likely, it will be a redundant RAID array for serving photographs.

IRIX does not do 'software' RAID, other than JBOD, RAID0 (striping) and RAID1 (plexing). The latter requires a license.

As far as hardware RAID goes: there are no hardware RAID controllers for SGI/MIPS systems. You'll need a disk array with built-in RAID capabilities, or a SAN server. Beware that there's a 2TB logical LUN limit in IRIX (this is a 32bit limit), arrays returning 64bit LUN numbers here will result in kernel panics and massive corruption. XFS does not have a 2TB limit, and XVM can be used to create large volumes out of 2TB or smaller LUNs.

I've got an old IBM DS4300 SAN server I occasionally use with my IRIX systems, it has ~ 8TB raw capacity (28*300GB). I can configure the disks in 2TB RAID5 LUNs and serve them up to an IRIX system which can then stripe them into a single, large volume using XVM (effectively a RAID50), and put a single XFS filesystem on it spanning the entire volume. SGI used to sell the same unit as the InfiniteStorage TP9300 and this is the way you were supposed to add large, redundant storage capacity to an SGI server.

The DS4300 is fully licensed and has many interesting enterprise features, but the noise level and power consumption of ~ 500W make this a silly thing to operate 24/7 at home. My current storage server (Supermicro, Haswell Xeon, 16TB raw capacity) idles at ~ 20W and is all but silent. And faster. Much faster.

Very informative stuff there, as I'm not terribly educated regarding RAID. So from the looks of things, I will definitely have to run a Linux port to get RAID.

Many will say, and some have already, get a small unit designed specifically for what you (I) seek. There's 2 issues with that...limited budget, and then what do I actually do with my Octane. In all honesty, IRIX serves me no real purpose. Especially with my extremely limited free time. Sure I could gut it and put "regular" PC components in the case, but time and money for that won't be available for quite some time. If I do that, I want to do it right, and do it good.

If Irix serves you no purpose, then give it to the Goodwill 'cuz Loonix will not do even 10% of what Irix does on that hardware. Basically, you can run a terminal on it, and that's all.

1. If you're just going to run Linux, why bother with SGIs?

2. SGI hardware is a poor fit for a NAS. Not only is it loud, hot, and power hungry, (the standard old workstation fare) the HW and SW aren't suited for it. (That is, IRIX is a terrible server and SGI hardware doesn't have HW RAID or proper space) If you're doing A/V stuff like rendering 3D or capturing video, it can make sense, but if you want a NAS... get something meant for it. A Synology, a whitebox, whatever.

It's not very secure, nor is it optimized for server workloads and applications.

By 2015 standards, sure, but by the standards of its time, IRIX was an outstanding server OS.
