Abstract: A storage unit for use within a dispersed storage network comprises an interface and a processing module operable to receive encoded data slices from a dispersed storage network client. The encoded data slices are associated with DSN logical addresses and the storage unit is allocated a range of DSN logical addresses in which the DSN logical addresses are found. The storage unit determines whether to store the encoded data slices in local memory of the storage unit or store them in remote memory. When the storage unit determines to store the encoded data slice to the remote memory it converts the DSN logical address into a local storage unit logical address and outputs the encoded data slices to the remote memory.

Abstract: A method for execution by a security module operating in a device of a dispersed storage network (DSN). The method begins by identifying storage unit(s) having security risk(s) and determining the security risk(s).

When security response is a DSN security response and level of the security response is a first network level, the method continues by instructing devices to perform at least one of revoking digital certificates of the identified storage unit and deleting access permissions of the identified storage unit.

Abstract: A distributed storage network (DSN) can include a DSN memory and a distributed storage (DS) managing unit in communication with the DSN memory. The DSN memory includes DS units physically located at different sites. The DS units store encoded data slices associated with a storage vault having a number of pillars and a read threshold. The number of pillars correspond to a number of encoded data slices generated from a particular segment of data, and the read threshold corresponds to subset of those encoded data slices required to reconstruct the particular segment of data. The DS managing unit assigns storage of particular encoded data slices to particular DS units based, at least in part, on a pillar associated with the encoded data slices and on the physical locations, e.g. the sites, at which the DS units are located.

The methods include obtaining transaction records, updating a cumulative data storage byte-hour count for storage of corresponding bytes of encoded data slices in the storage units of the DSN, and issuing byte-hour usage information based on the updated cumulative data storage byte-hour counts. Each transaction record can include one or more of an operation count, an operation type (e.g., read, write, delete), number of slice bytes transferred, number of slice bytes deleted, a timestamp, a user identifier, and a vault identifier. The updating can include one or more of identifying the one or more affiliated entities, determining a byte-hour adjustment (i.e., up or down) based on a transaction record, and updating a byte-hour record for affiliated entities based on the byte-hour adjustment.

Abstract: A method for execution by a computing device of a dispersed storage network (DSN). The method begins by receiving a data segment of a data object for dispersed storage error encoding. Prior to the dispersed storage error encoding, the method continues by determining whether to compress the data segment by predicting a first estimated processing cost based on estimated processing costs to compress the data segment to produce a compressed data segment and estimated processing costs to dispersed storage error encode the compressed data segment and predicting a second estimated processing cost based on estimated processing costs to dispersed storage error encode the data segment. When the first estimated processing cost compares favorably to the second estimated processing cost, the method continues by compressing the data segment to produce the compressed data segment and dispersed storage error encoding the compressed data segment to produce a set of encoded data slices.
