    摘要: An apparatus, system and method are disclosed for storing modified data. The apparatus includes a battery source for supplying backup power. The apparatus also includes a memory module for storing data. The memory module includes a backup portion and a non-backup portion. Only the backup portion is backed up by the battery source in the event of a power failure. A data flow module controls data flow into and out of the memory module. The data flow module stores modified data exclusively in the backup portion of the memory module.

    摘要: An apparatus, system, and method are disclosed for flushing cache data in a cache system. The apparatus includes a zero module and a flush module. The zero module executes an internal processor instruction to zero out a zero memory segment of a nonvolatile memory and a processor cache in response to a loss of primary power to the processor cache. The flush module flushes modified data from an address in the processor cache to a flush memory segment of the nonvolatile memory before the zero module puts a zero in the address. Advantageously, the zero memory segment is reserved within the memory and used to zero out the processor cache, effectively flushing the existing data from the processor cache to a flush memory segment of the memory.

    摘要: Provided are a method, system, and article of manufacture, wherein a controller receives encrypted data from a first storage unit coupled to the controller. The received encrypted data is stored in a second storage unit coupled to the controller, wherein the controller is capable of accessing the second storage unit faster in comparison to the first storage unit. The encrypted data is maintained in the second storage unit, until at least one condition is satisfied.

    摘要: Provided are a method, system and program for selecting a path comprising ports on primary and secondary clusters to use to transmit data at a primary volume to a secondary volume. A request is received to copy data from a primary storage location to a secondary storage location. A determination is made from a plurality of primary clusters of an owner primary cluster for the primary storage location, wherein the primary clusters are configured to access the primary storage location. A determination is made as to whether there is at least one port on the owner primary cluster providing an available path to the secondary storage location. One port on the owner primary cluster is selected to use to copy the data to the secondary storage location in response to determining that there is at least one port on the owner primary cluster available to transmit to the secondary storage location.

    摘要: Data management systems, such as used in disk control units, employ memory entry lists to help keep track of user data. Improved performance of entry list maintenance is provided by the present invention. Much of the protocol employed to conduct such maintenance is preferably performed by hardware-based logic, thereby freeing other system resources to execute other processes. New entries to the memory list are only allowed at predetermined addresses and entries are updated by writing a predetermined data pattern to a previously allocated address. Optionally, improved error detection, such as a longitudinal redundancy check, may also be performed in an efficient manner during entry list maintenance to assure the integrity of the list.
