The licensing for Gresham is pretty good. I don't have the details but IIRC
it's per Silo used. We've been using it for about 5 years and it works
great. We interface with Library Station on Z/OS wihout a hitch. As for
Library sharing, it does all the work. No need to go through TSM for that,
just
Well put, Wanda; in a nutshell, I would add...
- consider LTO, in lieu of DLT (ie, NO COLLOCATION) -- okay for diskpool
migration and non-collocated copypool data;
- use 3590/9840/9940 for the heavy duty cycle workloads... onsite copies,
collocated data, any workload generating lots of start/stop
The Gresham EDT software is needed for LAN-free and/or a SHARED library, and
then it's only needed on the LAN-free clients and TSM server --- not all
clients.
Also, I believe this middleware is not needed for IBM library; only STK
w/ACSLS.

I think you also need to consider duty cycles - how much data does TSM push
per day, how hard will you be pushing the tape drives.
In my discussions with IBM & STK, they BOTH say that the LTO drives are not
designed to replace "enterprise class" drives, meaning the 3590's or 9840's.
The construct
Our problem is that with our 9310 silo, if we go the IBM way we will have
to purchase a third party software, Gresham, that will manage the library.
