  • Program storage device for storage-aware flow resource
    Patent number: 7788389
    Abstract: A program storage device for managing resources in a storage system that is based on server resource usage is disclosed. The program storage device performs a method that allocates a command window to each of the servers accessing the resources, achieves an equilibrium state that balances the size of each server's command window and the amount of free resources, and maintains the equilibrium state by continually adjusting the size of each command window. The command window defines a limit on the number of outstanding storage requests that each server may maintain. The invention initially allocates a minimum sized command window.
