At least I can tell you what they are out of. (Thanks Google!)

HP NetServer Rack Storage/12
See page 92 of the attached. No pinouts unfortunately. There never are, that's why there are a number of threads from the "suck it and see" guys who have figured out how to make various supplies work. You might be able to find more info on the net by searching on the full device rather than just the PS though. Good luck.
