I just had this conversation with our local IBM storage folks. I can see us running out of space in our library sometime in the not to distant future. This would be a major mess since only full storage pools can be moved to a second library. I ran Legato with 2 libraries for many years - it worked very well although you have the expected problem of too much work occuring in one library while drives might be sitting idle in the other library. This gets into the administrative mess of trying to balance what tapes are in what library so that all tape drives are utilizied. While the local guys didn't have any answers, they did indicate that "Storage Tank" would/could address this problem. I don't know what Storage Tank is going to be, but it sounds like having to spend more money to get around a TSM limitation.
