    摘要: A system and method for efficiently storing data in a storage system. A data storage subsystem includes multiple data storage locations on multiple storage devices in addition to at least one mapping table. A data storage controller determines whether data to store in the storage subsystem has one or more patterns of data intermingled with non-pattern data within an allocated block. Rather than store the one or more pattern on the storage devices, the controller stores information in a header on the storage devices. The information includes at least an offset for the first instance of a pattern, a pattern length, and an identification of the pattern. The data may be reconstructed for a corresponding read request from the information stored in the header.

    摘要: Proactively providing corrective measures for storage arrays includes: receiving data from a storage array, the data including one or more events; detecting, in dependence upon a problem signature, one or more events from the data indicative of a particular problem, where the problem signature comprises a specification of a pattern of events indicative of the particular problem experienced by at least one other storage array; determining whether the particular problem violates an operational policy of the storage array, the operational policy specifying at least one requirement for an operational metric of the storage array; and if the particular problem violates the operational policy of the storage array, deploying automatically without user intervention one or more corrective measures to prevent the storage array from experiencing the particular problem.

    摘要: Secure cloud-based storage system management that includes: establishing, within a cloud-based services provider and based on one or more user credentials, a cloud-based user session to execute one or more commands on a remote storage system that includes physical storage devices; determining one or more data storage operations corresponding to the physical storage devices to implement the one or more commands on the storage system; and extending, based on using an access token based on the one or more user credentials to securely issue the one or more data storage operations to the remote storage system, the cloud-based user session to the remote storage system.
