The HP disk array rack is a pretty standard 19" EIA rack, with some
extra slots for mounting the disk drive slides.
Looking at the 7970, without the mounting kit, it's a standard 19" wide.
The right side flange has holes for mounting; the left side (the side
with the support hinges for the works) has a similar flange, but without
holes. Since mounting holes on an 19" rack are 18" apart, I could see
where just boring a couple of holes in the hinge-side flange and
countersinking them for flathead bolts would work to secure the drive.
On the DA cabinet, however, the side "skins" project about an inch
forward of the mounting rails, so you'd probably have to remove one to
get clearance to open the drive up for servicing. On the other hand, a
"naked" rack would probably work just fine.
My Fujitsu drive was new when I got it and so came with its own mounting
slides. Still is a heavy bugger, though.
