ENCODING DATA IN A DISPERSED STORAGE NETWORK

摘要

A method begins where a processing module segments data into data segments. On a data segment by data segment basis, the method continues with the processing module performing a decode threshold level of dispersed storage error encoding on a data segment to produce a set of decode threshold level encoded data slices and caching the set of decode threshold level encoded data slices. On a set by set basis, the method continues with the processing module performing a redundancy level of dispersed storage error encoding on the set of decode threshold level encoded data slices to produce a set of redundancy error coded data slices. The method continues with the processing module outputting at least one of at least some of a plurality of sets of decode threshold level encoded data slices and at least a corresponding some of a plurality of sets of redundancy error coded data slices.

1. A method for execution by a computing core of a computing device, the method comprises:
segmenting data into a plurality of data segments; on a data segment by data segment basis:
performing a decode threshold level of dispersed storage error encoding on a data segment of the plurality of data segments to produce a set of decode threshold level encoded data slices;caching the set of decode threshold level encoded data slices, wherein, for the plurality of data segments, a plurality of sets of decode threshold level encoded data slices are created; on set by set basis, performing a redundancy level of dispersed storage error encoding based on one of the plurality of sets of decode threshold level encoded data slices to produce a set of redundancy error coded data slices, wherein a plurality of sets of redundancy error coded data slices are created based on the plurality of sets of decode threshold level encoded data slices; and outputting at least one of:
at least some of the plurality of sets of decode threshold level encoded data slices; andat least a corresponding some of the plurality of sets of redundancy error coded data slices.
