    摘要： Synchronizing snapshots between storage systems, including: receiving, from a source storage system, an identification of a snapshot to be replicated to a destination storage system; identifying, from hint information stored on the destination storage system, a most recent version of the snapshot that is stored on the destination storage system; issuing, to the source storage system, a request for an identification of the differences between the snapshot to be replicated to the destination storage system and the most recent version of the snapshot that is stored on the destination storage system; receiving, from the source storage system, the identification of the differences; and issuing a request to transfer, from the source storage system to the destination storage system, data associated with the differences.

    摘要： Dynamically adjusting an error correction effort level of a storage device, including: receiving, from a storage array controller, an error correction effort level to perform when attempting to read data from the storage device; identifying that an attempt to read the data resulted in an error; and determining whether an amount of error correction effort level required to attempt to correct the error exceeds the error correction effort level to perform when attempting to read data from the storage device.

    摘要： Adjusting storage capacity in a computing system that includes a computing device configured to send access requests to a storage device characterized by a first storage capacity, including: reducing data; determining, in dependence upon an amount of storage capacity saved by reducing the data, an updated storage capacity for the storage device; and exporting an updated storage capacity to the computing device.

    摘要： A system and method for generating passwords for secure login to a storage array. A randomly generated root secret is utilized along with a compartment ID to generate a root password for logging into a storage array with root privileges. The root secret is encrypted with the public key of a public-private key pair and stored on the storage array. The encrypted root secret is then stored in the storage array. When root access is needed, a private key stored externally to the storage array is utilized to decrypt the root secret. The decrypted root secret is then used along with the compartment ID to regenerate the root password.

    摘要： A system and method for effectively scheduling read and write operations among a plurality of solid-state storage devices. A computer system comprises client computers and data storage arrays coupled to one another via a network. A data storage array utilizes solid-state drives and Flash memory cells for data storage. A storage controller within a data storage array comprises an I/O scheduler. The storage controller is configured to receive a read request targeted to the data storage medium, and identify at least a first storage device of the plurality of storage devices which contains data targeted by the read request. In response to either detecting or predicting the first storage device will exhibit variable performance, the controller is configured to generate a reconstruct read request configured to obtain the data from one or more devices of the plurality of storage devices other than the first storage device.

    摘要： A system and method for effectively scheduling read and write operations among a plurality of solid-state storage devices. A computer system comprises client computers and data storage arrays coupled to one another via a network. A data storage array utilizes solid-state drives and Flash memory cells for data storage. A storage controller within a data storage array comprises an I/O scheduler. The characteristics of corresponding storage devices are used to schedule I/O requests to the storage devices in order to maintain relatively consistent response times at predicted times. In order to reduce a likelihood of unscheduled behaviors of the storage devices, the storage controller is configured to schedule proactive operations on the storage devices that will reduce a number of occurrences of unscheduled behaviors.
