SAS and SATA under IRIX

This is premature but I'm too excited to wait. There's a bunch of LSI 3041X-R cards floating around here for around $25. So what the heck, it's an LSI 1064 chip, can't hurt to try.

Came, looks like a fake with a used LSI chip in the middle - either that or LSI product quality has gone down seriously. Tested it in an x86 kompewter first just in case

The hex 1000, device 0050 is the LSI sata/sas card. I don't have a drive to check it with yet but this could be a low-cost answer to the ide-sata-no-scsi-dvdrw-expensive scsi disk problem on the 3xxx platforms, anyhow.

Btw, when did they change reporting an IEEE1394 disk into being a "Fabric Disk" on the wrong controller ? Seems a little strange.

Stay tuned for the further adventures of Dick and Jane ....

Been a week now, didn't do to-the-death testing but pushed the disk pretty hard, seems reliable and don't see any noticeable speed differences in operation from the 15k scsi disks. Set ioconfig.conf aside and rebooted, Irix re-ordered my hardware inventory to make more sense. Kinda liked having a Fabric Disk for a while tho.

SATA CD-ROM has some problems tho :( That was one of my major interests in this whole exercise. Grrr.

Additional Notes

Hi, finally got around to installing an SAS3041X-R card in my Fuel, after futzing around getting it seated it worked fine as well. Stuffed a 200GB Western Digital IDE drive through an IDE->SATA bridge (picked up a couple for $10 each) and everything worked great, GUI tools found, initialized, and mounted the drive like it was a standard SCSI drive. A+++++++, would try again!

As long as has either the LSISAS1064 or LSISAS1068 chipset it should work - I didn't see a specific mention of the SAS3041XL-S nomenclature on LSI's site. You might want to confirm it's the correct height profile, the "L" in the product name might mean it's equipped with a Low-profile bracket? <though it looks like the retail version comes with both the low and normal height brackets>.
