Advantages of using SRMs
Smooth synchronization between storage resources
- Pinning file, releasing files
- Allocating space dynamically on as “needed basis”
Insulate clients from storage and network system failures
- Transient MSS failure
- Network failures
- Interruption of large file transfers
Facilitate file sharing
- Eliminate unnecessary file transfers
Support “streaming model”
- No need for space pre-allocation by SRMs
- No need for space reservation and release by client
- No need for accounting and charging
Control number of concurrent file transfers
- From MSS – avoid flooding and thrashing
- From network – avoid flooding and packet loss
