    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: An apparatus, system, and method are disclosed for reliably updating a data group in a data replication environment. The apparatus, system, and method reliably update the data group by receiving an updated data group sent from a first storage medium to a second storage medium, comparing the updated data group with a previous data group previously existing on the second storage medium and writing the updated data group to the second storage medium. The read-before-write and differencing method disclosed maintain reliability by storing multiple copies of changes made to the second storage medium during and after the write process.

    摘要: A method to coordinate interconnected information storage and retrieval systems, where each of the information and storage systems is capable of communicating with one or more host computers. The method provides a plurality of controllers and one or more information storage and retrieval systems, where each of the plurality of controllers is disposed in one of the one or more information storage and retrieval systems. The method designates one of the plurality of controllers as a master controller and the remaining controllers as target controllers. The method then generates one or more master controller commands by the master controller, and provides those one or more master controller commands to each of said target controllers, where the one or more master controller commands cause said target controllers to adjust the flow of data into and out of the one or more information storage and retrieval systems.

    摘要: Method, device and computer program product for determining a characteristic of an identifiable component. The method includes: receiving identification information representative of an identity of components that belong to a group of components, determining at least one characteristic of an identifiable component in response to the received identification information, and performing at least one characteristic responsive operation. The device includes an identifiable component and a component characteristic determiner. The component characteristic determiner is adapted to receive identification information representative of an identity of components that belong to a group of components and to determine at least one characteristic of the identifiable component in response to a relationship between the received identification information and reference identification information. The device is adapted to perform at least one characteristic responsive information.
