  • USE OF VIRTUAL TARGETS FOR PREPARING AND SERVICING REQUESTS FOR SERVER-FREE DATA TRANSFER OPERATIONS
    Publication number: 20080288670
    Abstract: A system and method are disclosed for utilizing virtual targets and abstract copy orders in preparing and servicing requests for server-free data transfer operations in a data storage network. The abstract copy orders represent data transfers between virtual targets and real devices. They allow source target copy orders to be prepared separately from destination target copy orders. The abstract copy orders may then be converted into concrete copy orders involving only real device targets for execution by a data mover that implements the server free data transfer operations.

  • System for allocating storage performance resource
    Patent number: 7334032
    Abstract: A method and structure for a multi-workload storage system is disclosed that is adapted to determine if an additional workload can be placed on the storage system. The invention has storage elements and a proxy load generator connected to the storage elements. The proxy load generator is adapted to create a proxy workload based on an additional workload from a potential client. The proxy workload has a reduced duty cycle when compared to a duty cycle of said additional workload. A control server is connected to the storage elements and the proxy load generator. The control server applies the proxy workload to the storage elements during discontinuous time slices.
