摘要： Based on information security rules, it is not possible to take out a failure HDD to the exterior of a facility for replacement without erasing data therefrom. According to the present storage sub-system, a slot in which failure has occurred and a slot not registered to a configuration information of a storage sub-system are used to simultaneously perform correction copy to a spare HDD and data erase of the failure HDD in parallel, so as to enable the failure HDD to be brought out to the exterior of the storage facility. Further, time required from when failure has occurred to the HDD to data recovery is shortened, so as to prevent deteriorated redundancy that may be caused by another failure occurring during data recovery and to reduce the risk of data loss.

摘要： A method begins by determining that a disk drive of a slice server has been replaced with a new disk drive. The method continues by identifying a data slice that was stored on the disk drive and identifying a data segment based on the identified data slice. The method continues by identifying other slice servers that are storing other data slices of the encoded data segment. The method continues by retrieving, from the other slice servers, a sufficient number of the other data slices to reconstruct the data segment and decoding the sufficient number of the other data slices to reconstruct the data segment. The method continues by encoding the reconstructed data segment in accordance with the information dispersal algorithm to produce a new set of data slices. The method continues by selecting a data slice of the new set of data slices as a rebuilt data slice.

摘要： A method begins with a set top box determining whether a content request is regarding playback of stored content or streaming of broadcast content. When the content request is regarding playback of stored content, the method continues with the set top box determining whether to retrieve the stored content for a group of set top boxes in a common area or from storage units DSN memory. When the stored content is to be retrieved from the group of set top boxes, the method continues with the set top box obtaining, from at least some of the set top boxes, the decode threshold number of encoded data slices for each set of encoded data slices corresponding to the stored content. The method continues with the set top box decoding, for each set of encoded data slices, the decode threshold number of encoded data slices to reconstruct the stored content.

摘要： A resilient distributed replicated data storage system is described herein. The storage system includes zones that are independent, and autonomous from each other. The zones include nodes that are independent and autonomous. The nodes include storage devices. When a data item is stored, it is partitioned into a plurality of data objects and a plurality of parity objects are calculated. Reassembly instructions are created for the data item. The data objects, parity objects and reassembly instructions are spread across nodes and zones in the storage system according to a policy for the data item. When a zone is inaccessible, a virtual zone is created and used until the intended zone is available. When a read request is received, the data item is prepared from the lowest latency nodes according to the reassembly instructions, and a virtual zone is accessed in place of a real zone when the real zone is inaccessible.

摘要： A data access request is received specifying a data block stored in a stripe of a parity group that includes a plurality of data storage devices to store data blocks and a parity storage device to store parity information for the data. The stripe includes a data block from each of the plurality of data storage devices and the stripe includes a parity block from the parity storage device. An error is detected in the data block specified by the data access request. The error is identified as a lost write error for the data block or a lost write error for the parity block. Identifying the error includes comparing a first storage device signature stored in a metadata field associated with the data block to a second storage device signature stored in a label block identifying a data storage device where the data block is stored.

摘要： A user device includes a browser module, a DSN interface to a local or external DSN memory and a DS processing module coupled to the DSN interface for storing and retrieving the data object from the DSN memory, wherein the data object is divided into a plurality of data segments and wherein each of the plurality of data segments is stored in the DSN memory as a plurality of encoded data slices that are generated based on an error encoding dispersal function. The browser module is operable to interpret a user input as a request to display a data object, determine the data object is stored in the DSN memory, request the DS processing module to retrieve the data object from the DSN memory and request an application program to open the data object for display.
