Abstract: A method begins with a processing module of a centralized digital video storage (DVS) system storing, for playback, a plurality of sets of encoded data slices in storage units, where multi-media content is encoded to produce the plurality of sets of encoded data slices. The method continues with the processing module monitoring the storage units for a failure mode and monitoring a number of subscriber devices requesting playback of the multi-media content. The method continues with the processing module determining whether a sufficient number of unique combinations of a decode threshold number of encoded data slices per set of slices exists to service playback of the multi-media content. When the sufficient number of the unique combinations do not exist, the method continues with the processing module reassigning unique combinations of the decode threshold number of encoded data slices per set of encoded data slices to some of the subscriber devices.

Abstract: A method begins by generating list range requests. A list range request includes a payload section and a protocol header section. The payload section includes a start slice name field regarding a start slice name of a slice name range; an end slice name field regarding an end slice name of the slice name range; and a maximum response count field regarding a maximum slice name response count. The protocol header includes a payload length field that represents a length of the payload section and an operation code field to indicate the list range request operation. The list range request includes a request to provide a list of slices names corresponding to stored encoded data slices associated with slice names within the slice name range. The method continues by sending the range requests to storage units of the DSN.

Abstract: A method begins by a dispersed storage (DS) processing module receiving data for storage and generating a dispersed storage network (DSN) source name for the data. The method continues with the DS processing module determining whether substantially identical data to the data has been previously stored in memory of the DSN.

Abstract: A method begins by a processing module dispersed storage error encoding data to produce a set of encoded data slices and sending a set of write request messages to a set of dispersed storage (DS) units, wherein each of the set of write request messages includes an encoded data slice of the set of encoded data slices.

Abstract: A distributed storage integrity system in a dispersed storage network includes a scanning agent and a control unit. The scanning agent identifies an encoded data slice that requires rebuilding, wherein the encoded data slice is one of a plurality of encoded data slices generated from a data segment using an error encoding dispersal function. The control unit retrieves at least a number T of encoded data slices needed to reconstruct the data segment based on the error encoding dispersal function. The control unit is operable to reconstruct the data segment from at least the number T of the encoded data slices and generate a rebuilt encoded data slice from the reconstructed data segment. The scanning agent is located in a storage unit and the control unit is located in the storage unit or in a storage integrity processing unit, a dispersed storage processing unit or a dispersed storage managing unit.

Abstract: A processing module of a computing device alternatingly sends a stream of data to a first or second processing device. When receiving the stream of data, the first processing device performs a first portion of a dispersed storage error encoding function on the received stream of data to produce a plurality of sets of a threshold number of slices and writes the plurality of sets of the threshold number of slices into first memory of a dispersed storage network (DSN). When not receiving the stream of data, the first processing device reads the plurality of sets of the threshold number of slices from the first memory, performs a second portion of the dispersed storage error encoding function using the plurality of sets of the threshold number of slices to produce a plurality of sets of redundancy slices, and writes the plurality of sets of redundancy slices into second DSN memory.

Abstract: A method begins by a dispersed storage (DS) processing module storing a data portion in a dispersed storage network (DSN), where the data portion is associated with a set of data index keys, a version index key, and with a set of portion index keys.
