I would say run the TSM server on AIX since u have it in house already. W2K would be the next choice with the AS/400 being last on the list for sure.

We are in the process of ditching our current BackupExec/ArcServe setup in favor of a central TSM environment. We have decided to expand our existing 3494 tape library (additional frame w/ 2 3590 drives, SCSI) but haven't selected the hardware/operating system for the TSM server. These are our options: Dell 2600/Win2000 pSeries/AIX iSeries820/PASE Any recommendations for one system over another for the TSM server? The Win2000 option would be the cheapest but would it cause headaches down the road? thanks, Mark Cini Systems Administrator CorrFlex Display & Packaging
