Has anyone ever put an ssd in a scsi sgi computer

Edit: With apologies, I no longer wish to have involvement with SGUG or SGI communities in general,
and have also chosen to remove all of my content. Many things have changed since I co-founded, named, and ultimately
then left SGUG. There are many good people around, to whom I apologize for frustrating by removing these things, and
also many petty people that over the years whittled down both the enjoyment as well as sense of obligation I used to
feel to anyone else regarding what was ultimately just a hobby. Unfortunately one of the latter now writes the rules
and so it is time for me to take my things and go.

This message will replace all of my previous forum posts because deleting threads that I started would have removed
other peoples' posts.

bought a simple LSI PCI-X card and connected a SATA SSD to his old SGI!

It only works in the Fuel/Tezro/Origin 3x0 machines, but hey, it's something!

FWIW, I just did this recently in an Origin 350. Works great; speeds are pretty excellent:

I did a fresh install with both the SATA SSD and a SCSI HD in there. You have to use the SCSI HD as the boot partition -- or, I believe, load the kernel via bootp() which I haven't done yet but I intend to try. I don't see why it wouldn't work. I partitioned the scsi drive so that inst would have something to copy the install onto, and then once I was in inst I dropped to the shell, used fx to partition the SATA drive (since it was visible at that point), and then in inst swapped mounts so that /usr was the SSD. That way I installed to the SSD from the start.

I made a more detailed writeup here: LSI SATA in Origin 350 - HackMD

Note I didn't have to do any firmware downgrading; maybe I got lucky? I had firmware version 1.26.0.0 on a SAS3041X-R.

Edit: the SSD itself is a 500gb Samsung 840 EVO I had laying around.

Hello, thank you guys for sharing the good steps to solve the problem of Arius. I had the same issue with the old hard drives, and the main problem was that I was unable to open the required folders, so I tried the different transfer services to archive those files and folders and reopened them via Winrar, this didn't work properly, so I decided to search for a solid hard disk recovery software/service. Hopefully, I found a raid data recovery website that helped me a lot with fixing errors in my disks.

I haven't tried for most of the reasons mentioned above. Even the v6 SCSI2SD is super slow, and SGI machines don't strike me as the type that would be happy about having slow drives in them. Most of my SGI's came to me with their original hardware in them, and even the older machines always had HDD's in them that were considered fast in their day. Heck, I haven't even used a SCSI2SD in any other machine, I have a load of Ultra320 drives from some array's I decommissioned a few years back and have been slowly using those up.

Seems to be lots of cheap SAS SSDs on the used market. I understand these SAS use the SCSI command set. Does a parallel SCSI to serial SCSI device or chip exist that would allow these SAS SSDs to work in an SGI machine?
