been running with six 3494's for 5+ years...
Love'em !
had them spread out across 4 data centers in 3 states...
as environments have changed I've been able to pull resources (cabinets &
drives) from one ATL and put them on another
very flexible
the six I deal with were bought new 5+ years ago and I've had very little
problems
two accessors suffered a resistor burnout that required a board replacement
each time the library was just put in manual mode while IBM went to
get the part & replace (net results of zero outage)
we do have an excellent IBM CE as far as PM goes !
we run dual grippers (which is a flip of a coin)
right now our configurations are
1-2frame 6-3590
2-3frame 6-3590 (ea.)
1-6frame 12-3590
2-8frame 16-3590 (ea.)
I think I got that right... well, they will be that way when my most recent
movement of frames is complete ;-)
Oh, and they (all the tsm environments) take in 1.5-ish TB of compressed
client data nightly so there are a lot of tapes being written & reclaimed
daily

Subject: IBM 3494 Automated Tape Library Information needed
Hi.
We are currently using TSM (formerly known as ADSM) to provide
backup services for approximately 3,000 desktops. The server
is 9121-570 mainframe running VM/ESA 2.4. The tapes used for this
service are Magstar 3590s which were recently upgraded to Model E11.
The next step in our plan is to automate the tape mounting activity.
That's where I need your advice!
We're considering purchasing a used IBM 3494 automated tape
library (ATL), and moving our 3590 drives into the ATL.
We're looking for feedback on 3494s - reliability, performance,
serviceability, etc. It would be really useful if you would
also include information such as the age of your 3494, purchased
new or used, library size, dual or single gripper, activity levels
or anything else you think might be pertinent.
Also, any information as to implementaion on VM would be helpful as
well.
Thanks in advance for any information.
