    摘要: A computer-implemented method for efficient data storage is provided. A first storage medium associates data stored on one or more data storage media with a unique identification value (ID) for the purpose of determining de-duplication status of the data. In response to receiving a request to read the data from a logical address, the first storage medium retrieves the data from a second storage medium based on the unique ID. In response to receiving a request to write the data to a logical address, the one or more data storage media store at least one copy of the data based on the de-duplication status of the data.

    摘要: A method for modifying executable logic code stored on a computing system is provided. The method comprises assessing a risk level associated with modifying a first code block and assessing an urgency level associated with modifying the first code block and then evaluating whether the first code block should be modified.

    摘要: A method for storing data received from a host processor at a primary storage subsystem in a data storage system includes writing the data to a first volatile cache memory in the primary storage subsystem and copying the data from the primary storage subsystem to a secondary storage subsystem. The second subsystem writes the copied data to a second volatile cache memory and returns an acknowledgment to the primary storage subsystem responsively to writing the copied data to the second volatile cache memory and prior to saving the data in the second non-volatile storage media. The primary storage subsystem signals the host processor that the data have been stored in the data storage system responsively to the acknowledgment from the secondary storage subsystem.

    摘要: A method for managing a data storage system includes maintaining a record on a secondary storage subsystem, which is predictive of locations to which data are to be written on a primary storage subsystem by a host processor. Upon receiving at the primary storage subsystem, from a host processor, the data to be written to a specified location, if the specified location is not included in the record, the primary storage subsystem sends to the secondary storage subsystem so as to cause the secondary storage subsystem to update the record. The primary storage subsystem signals the host processor that the data have been stored in the data storage system responsively to receiving the data and to receiving an acknowledgment from the secondary storage subsystem indicating that the record has been updated.

    摘要: A method for managing a data storage system includes copying data stored on a first storage subsystem to a second storage subsystem in an asynchronous mirroring process. A record is maintained on the second storage subsystem, indicative of locations at which the data have been updated on the first storage subsystem and have not yet been copied to the second storage subsystem. Upon receiving at the second storage subsystem, from a host processor, a request to access the data stored at a specified location on the data storage system, if the specified location is included in the record, the second storage subsystem initiates a synchronous transfer of the data at the specified location from the first storage subsystem.
