HYBRID CENTRALIZED AND AUTONOMOUS DISPERSED STORAGE SYSTEM STORAGE METHOD

摘要

A dispersed data storage method for execution by a dispersed storage (DS) unit. In various embodiments, the method begins when the DS unit receives a plurality of encoded data slices and associated metadata. The metadata is interpreted to determine storage instructions regarding the encoded data slices. When the storage instructions indicate, for example, a daisy chain storage dispersal approach, the DS unit locally stores first encoded data slices (e.g., the first encoded data slices of a set of encoded data slices) and forwards other encoded data slices to at least one other DS unit. In other exemplary embodiments, sequential and/or one-to-many dispersal approaches may be utilized. Further, the DS may employ a variety of criteria to solicit other DS units for storage of encoded data slices.

1. A method for execution by a dispersed storage (DS) unit, the method comprises:
receiving a plurality of sets of encoded data slices, wherein a read threshold number of encoded data slices of a set of the plurality of sets of encoded data slices is required to recover a data segment of data and wherein an individual encoded data slice of the set of encoded data slices yields substantially no information regarding the data segment; receiving metadata associated with the plurality of sets of encoded data slices; interpreting the metadata to determine storage instructions regarding the plurality of sets of encoded data slices; and when the storage instructions indicate daisy chain storage:
locally storing first encoded data slices of each set of encoded data slices; andforwarding other encoded data slices of the sets of encoded data slices to at least one other DS unit.
