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.
