HRM Functionality
Same as DRM, but also:
- Queuing of file staging and archiving from/to tape
- Reordering of request to optimize tape mounting and reading (ordered by files on the same tape)
- Monitoring staging/archiving progress and error messages from MSS (e.g. HPSS)
- Reschedules transfers that failed
Enforce MSS policy
- Number of simultaneous file transfer requests
- Fair treatment of users when reordering tape requests
Same interface (methods, API) as DRM
