摘要： A method begins by a dispersed storage (DS) processing module of a dispersed storage network (DSN), when in a rebuilding mode, determining a level of rebuilding urgency, where the level of rebuilding urgency is based on an inversely proportional function of a level of error encoded redundancy for error encoded data giving rise to the rebuilding mode. When the level of rebuilding urgency is at or above a critical level, the method continues with the DS processing module placing a set of storage units of the DSN in a critical rebuilding mode, where, when in the critical rebuilding mode, the set of storage units prioritize rebuilding of the error encoded data giving rise to the rebuilding mode over other error encoded data operations.

摘要： A method for transferring encoded data slices from a first storage unit to a second storage unit begins by a processing module ascertaining a first mathematical process used to determine that the encoded data slices are to be stored in the first storage unit, where the first mathematical process includes a first mathematical function sequence and a first set of coefficients. The method continues with the processing module determining a second mathematical process, which indicates that the encoded data slices are to be stored in the second storage unit, where the second mathematical process corresponds to an adjustment of at least one of the first mathematical function sequence and the first set of coefficients. The method continues with the processing module transferring, based on a transfer command, the encoded data slices from the first storage unit to the second storage unit utilizing the second mathematical process.

摘要： A method includes determining whether at least a portion of a data object requires rebuilding, wherein the data object is stored in accordance with a RAID formant. The method further includes, when the at least a portion of the data object requires rebuilding, reconstructing stripes from sets of data blocks and parity blocks. The method further includes dividing the recovered data object into data segments. The method further includes dispersed storage error encoding the data segments in accordance with dispersed storage error encoding parameters to produce sets of encoded data slices, wherein a data segment is recoverable from a threshold number of encoded data slices. The method further includes issuing sets of write requests to write the sets of encoded data slices into storage units of a dispersed storage network (DSN).

摘要： A method begins by a first computing device of a dispersed storage network (DSN) of a plurality of DSNs receiving a data segment for storage, encoding the data segment using a dispersed storage error encoding function to produce a set of encoded data slices, where each DSN of the plurality of DSNs utilizes the dispersed storage error encoding function, and generating a set of DSN addresses for the set of encoded data slices using a deterministic function. The method continues with a set of storage units of the DSN storing the set of encoded data slices using the set of DSN addresses. The method continues with storage units of the set of storage units and of another set of storage units of another DSN coordinating to store copies of encoded data slices of the set of encoded data slices in corresponding storage units of both sets of storage units.

摘要： A method begins by a processing module receiving an encoded data slice for storage. The method continues with the processing module obtaining metadata associated with the encoded data slice and interpreting the metadata to determine whether the encoded data slice is to be stored in a first access speed memory or a second access speed memory, wherein the first access speed memory has a higher data access rate than the second access speed memory. The method continues with the processing module storing the encoded data slice in a memory device of the first access speed memory when the encoded data slice is to be stored in the first access speed memory and storing the encoded data slice in a memory device of the second access speed memory when the encoded data slice is to be stored in the second access speed memory.

摘要： A method begins by a requesting entity sending a distributed storage network (DSN) access request to a request verification entity, wherein the DSN access request includes a signed certificate and DSN accessing information. The method continues by a request verification entity sending a signed DSN access request to the requesting entity when the request verification entity signs the DSN access request after verifying the signed certificate and the DSN accessing information. The method continues by the requesting entity sending the signed DSN access request to a DSN accessing entity. The method continues by the DSN accessing entity sending an authorized DSN access request to the DSN via a network connection when the DSN accessing entity verifies a signature of the request verification entity, wherein the authorized DSN access request includes, at a minimum, the DSN accessing information.
