It's listed in the doc under ADIC i500 is it not?    They can hold
either IBM or HP drives, both of which are supported.

Quantum have announced that after their merger with ADIC that they're
keeping the i500 in favour of some of their PX models.

compatibility guide?

Hi,

How important is it that a tape library be listed in Legato's hardware
compatibility guide?

I was looking at a Quantum I500 series library with LTO-3, but it's not
listed in this document, but, of course, LTO-3 is largely supported. 
Obviously, Legato can't test everything, but it is comforting to know
you have something that they have officially sanctioned. Thing is,
though, that a lot of the libraries listed are now EOL. Seems a lot of
newer stuff is out there now but may not be on the list.

I like the concept of the stackable libraries since they allow you to
add on and are rack mountable, but the one thing that can burn you is
that if the manufacturer EOLs the product - never mind the fact that
they may support it for several more years after that - you can't buy
another chassis. And because you can't purchase another chassis, you
can't add any more drives unless your existing chassis can take more. 
Seems many of the smaller ones will only take 2 drives each, so there's
a good chance you'll already be maxed out, so I like the I500 since you
add in 9U increments; it scales to larger increments, so if we get the
base chassis (2 drives, 36 slots), we can also buy a 9U add-on that can
support another 4 drives and up to 92 more slots. So, if the product is
later EOL, we can still add 4 more drives. The Quantum PX502 and some of
the other models only allow 2 drives max per chassis, so you'd have to
buy a lot of empty chassis upfront to be be covered.
