    摘要： In one implementation, a method includes identifying a first content-dependent feature associated with a data sector. The method further includes determining a baseline data sector associated with the data sector. The method further includes determining, by a processing device, a content-dependent delta between the first content-dependent feature and a second content-dependent feature of the baseline data sector. The method further includes providing the content-dependent delta and an indicator to the baseline data sector for storage on a plurality of storage devices.

    摘要： Protecting an encryption key for data stored in a storage system that includes a plurality of storage devices, including: reading, from at least a majority of the storage devices, a portion of an apartment key; reconstructing the apartment key using the portions of the apartment key read by the majority of the storage devices; unlocking the main portion of each of the storage devices utilizing the apartment key; reading, from the main portion of one of the storage devices, a portion of a third-party resource access key; requesting, from the third-party resource utilizing the third-party resource access key, an encryption key; receiving, from the third-party resource, the encryption key; and decrypting the data stored on the storage devices utilizing the encryption key.

    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： Incremental RAID stripe update parity calculation includes receiving a first portion of data of a RAID stripe for writing to a first memory location of a plurality of solid state drives. A first parity value is calculated for the first portion of data of the RAID stripe. A second portion of data of the RAID stripe is received for writing to a second memory location that is different from the first memory location A second parity value is calculated in dependence upon the second portion of the data of the RAID stripe and upon the first parity value Responsive to successfully writing the second portion of data of the RAID stripe, the first parity value is replaced with the second parity value.

    摘要： A system and method for efficiently distributing data among multiple storage devices. A data storage array receives read and write requests from multiple client computers. The data storage array includes multiple storage devices, each with multiple allocation units (AUs). A storage controller within the data storage array determines a RAID layout for use in storing data. In response to determining a failure of a first AU, the storage controller begins reconstructing in a second AU the data stored in the first AU. For read and write requests targeting data in the first AU, the request is serviced by the first AU responsive to determining no error occurs when accessing the first AU.
