摘要： A file system interface to a dispersed data storage network is disclosed. The disclosed interface accepts read and write commands from a file system resident on a user's 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 by a dispersed storage (DS) processing module detecting a storage error of an encoded data slice associated with a storage server within a maintenance free storage container. The method continues with the DS processing module determining failure mode information for the storage server and other storage servers and determining a rebuilding protocol for the encoded data. When the determined rebuilding protocol is a zero information gain (ZIG) protocol, the method continues with the DS processing module identifying a decode threshold number of storage servers from the other storage servers of the maintenance free storage container and from storage servers of another maintenance free storage container, retrieving zero information gain (ZIG) partial encoded data slices from the decode threshold number of storage servers, and decoding the ZIG partial encoded data slices utilizing a ZIG dispersed storage error coding function to reproduce the encoded data slice.

摘要： A dispersed storage network utilizes a virtual address space to store data. The dispersed storage network includes a processing unit operable to slice a data segment of a data object into data slices and create a slice name for each of the data slices. The slice name includes an identifier of the data object and a virtual memory address of a virtual memory associated with the dispersed storage network. The processing unit further outputs each of the data slices and the respective slice names to a corresponding storage unit for storage of the data slices therein.
