I'll address this last item: HSM works well in the following environment: 1) the client is a large file server with a high percentage of static, unaccessed files; 2) the tape library has a fast mount and seek time (the IBM 3575 comes to mind); and 3) the client has a large *fast* processor. Disk Xtender 2000 is pretty hard on the processor during the windows you set for its activity. I would *never* run it during the production day, and I would not run it during backup times. I wish that OTG had developed a TSM-compliant HSM client for Windows, instead of an HSM server. I wish wish wish that Tivoli would create an HSM client for Windows. I know it will never happen, because of the robust server functionalities that Microsoft's server OSs have never had.
