摘要： A method with a computer generating a first set of access requests regarding a first set of encoded data slices and storage units of a dispersed storage network. A first data segment is encoded into the first set of encoded data slices. The method continues with the computer generating a second set of access requests regarding a second set of encoded data slices and the storage units. A second data segment is encoded into the second set of encoded data slices. The method continues with the computer grouping the first set of access requests and the second set of access requests to produce a set of combined requests. The method continues with the computer sending the set of combined requests to the storage units.

摘要： A data object interface to a dispersed data storage network is disclosed. The disclosed interface accepts read and write commands from a client computer and generates network commands that are forwarded to slice servers that form the storage component of the dispersed data storage network. The slice servers then fulfill the read and write commands.

摘要： A method begins a first rebuilder application identifying a data slice having a storage error. The method continues with the first rebuilder application or a second rebuilder application identifying a data segment based on the identified data slice. The method continues with the second rebuilder application identifying one or more other slice servers that are storing other data slices of the encoded data segment. The method continues with the second rebuilder application receiving a sufficient number of the other data slices to reconstruct the data segment and decoding them to reconstruct the data segment. The method continues with the second rebuilder application encoding the reconstructed data segment in accordance with the information dispersal algorithm to produce a new set of data slices and selecting one of them as the rebuild data slice.

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.
