    摘要： A system, method, and computer-readable storage medium for protecting a set of storage devices using a secret sharing scheme in combination with an external secret. An initial master secret is generated and then transformed into a final master secret using an external secret. A plurality of shares are generated from the initial master secret and distributed to the storage devices. The data of each storage device is encrypted with a device-specific key, and this key is encrypted using the final master secret. In order to read the data on a given storage device, the initial master secret reconstructed from a threshold number of shares and the external secret is retrieved. Next, the initial master secret is transformed into the final master secret using the external secret, and then the final master secret is used to decrypt the encrypted key of a given 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 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, method, and computer-readable storage medium for protecting a set of storage devices using a secret sharing scheme. The data of each storage device is encrypted with a key, and the key is encrypted based on a shared secret and a device-specific value. Each storage device stores a share and its encrypted key, and if a number of storage devices above a threshold are available, then the shared secret can be reconstructed from the shares and used to decrypt the encrypted keys. Otherwise, the secret cannot be reconstructed if less than the threshold number of storage devices are accessible, and then data on the storage devices will be unreadable.
