I'm fairly sure most ALL LTO drives are from a very few vendors.    
Quantum bought Certance, fka Seagate Tape, fka Archive, and acquired the 
whole line of LTO from them, prior to that, Quantum was the primary OEM 
manufacturer of DLT drives.

HP may in fact make their own tape transport, as at least some of their 
LTO drives have slightly different performnace specs than everyone elses.

I'm ussing a HP Ultrium LTO2 "1/8 Autoloader", which is a simple 8 tape 
changer.    Love/hate thing, it works great, holds 8 tapes, I can do 
rotating backups (BTW, LTO2 backs up at hard drive speeds), but its kind 
of a pain to remove tapes from the rotation, the backup software I'm 
using supports a concept of a 'mailslot' where the software ejects a 
tape from a library, but this drive only seems to support manual eject, 
so it makes library management kinda difficult.

The HP "1/8 Autoloader" I have is identical to this Quantum unit,
except for the trim details of the faceplate

If I was doing it again, I'd get one of these, 
http://www.quantum.com/Products/TapeLibraries/PX502/Index.aspx (IBM, HP, 
Dell, etc all have their own OEM labeled versions of this same 
library).   This family supports 1 or 2 internal LTO or DLT drives, and 
up to 38 tape slots.
