Yale uses Panasus PanFS, a massive parallel storage system, to store research 
data generated from HPC clusters.  In considering feasibility to backup PanFS 
using TSM,
we are concerned about whether TSM is appropriate to backup and restore:

 1. very large volumes,
 2. deep  subdirectory hierarchy  with 100's to 1000's of sublevels,
 3. large numbers of files within individual subdirectories,
 4. much larger numbers of files within each directory hierarchy.

Are there effective maximum limits for any of the above, beyond which
TSM becomes inappropriate to effectively perform backups and restores?

Please advise about the feasibility and any configuration recommendation(s)
to maximize PanFS backup and restore efficiency using TSM.

Thanks for your help.
