Hi I disagree. Except the price tag ...
Unfortunatelly, TSM built-in library manager is not smart enough for large ACSLS libraries. How do you handle multiple ACSLS scratch pools without external library manager (Gresham or whatever) ? What path optimization can be done without external library manager ? (to avoid using the pass-through) Let's say I would like TSM to choose the closest free drive (same LSM) to mount a tape ... ... TSM uses tape drives in sequential order. If your TSM Server hosts several instances, Gresham allows you not to depend on one *critical* TSM library manager instance. With an external manager, each instance is able to mount/dismount tapes as a stand alone server would do. In a nutshell, I would say the more larger is your library(ies), the worth gresham is. Actually i would say the drawback is only the price, and the fact you'll will have to get a license for each storage agent. (;_;) If you don't want to manage SL8500s and such large librairies, in that cases, forget about Gresham and use TSM builtin manager.

Indeed, getting multiple TSM instances resync'd with Gresham can cause (temporary) inability to use the library during that resync. Stability isn't usually an issue with either TSM library management or Gresham. Gresham requires additional administration that TSM's library management doesn't need. And TSM's library management doesn't have an outrageous price tag.
