ISTR, it's some version of the Tahiti.

Back in the day, we had a bunch of them in Artecon enclosures and rand them under Solaris 6 using a special driver. For later versions of Sol, I recall that we had to change a jumper so the drive identified itself as a disk drive rather than an optical drive. I'm assuming that if I set the dip/jumper that way, then it should just work under Mac OS X with Disk Utility, no?
