"Question: are you currently licensed per TB?? not PVUs? Can you share the experience in a new post (licensing sub-forum)? "
I'll do my best to give my experience with TSM and licensing on a capacity basis.
Why we went Capacity: with close to 400 servers, all of them dual proc and multi core the cost go to PVU (and the crazy math involved) was not an attractive option. So we took our current backup solution, and our intended retention policies and shipped them to IBM to quote us out how much capacity we would need for the next 3 years. We were priced out at roughly 30tb of capacity....not nearly enough when you include full backups of exchange with our crazy retention policies!
So, now we are back peddling to come into scope with how IBM thought we would be doing our backups, and we're still going to be short on the exchange side, but we'll be closer tot he 30tb we purchased.
On the file server backup side, we are sending everything to a dedup pool, this is working great, we're captureing all of our data (with the occasninal 'failed 12' tossed in for fun) and keeping for the most part on disk (some spills over to a tape pool if it's been a busy day).
As far as TB vs PVU, i'd say if you have alot of servers and little data go TB, if you have a few servers and alot of data go PVU, if your someplace in grey area (alot of servers and data) price them both out, and if $$ is a major concern, go with somebody else, cause it isn't going to be cheap!
Rore, any specific questions you might have, feel free to ask, I'll do my best to answer in a timely manner.
