That was SCSI. (Well, dual qlogic fiber channel controllers that pretended to be scsi.) I've also encountered a couple companies selling 14-drive enclosures (IDE, they rackmount in a 3U or 4U) that are turned into big software raid systems for data hosting. And of course, you might want to talk to IBM and their global file system stuff, and their implementation of the logical volume management stuff last year (what was not the one that Linus eventually went with, I believe...) Does this count? (I kind of doubt IBM, HP, or Sun are insterested in tools for individual end-users...)
