Utilizing local memory and dispersed storage memory to access encoded data slices

摘要

A method begins by a processing module establishing a dispersed storage (DS) error coding function based on a number of local memories associated with the computing device, wherein a decode threshold number of the DS error coding function corresponds to the number of local memories. The method continues with the processing module encoding a data segment of data utilizing the DS error coding function to produce a set of encoded data slices, of which the decode threshold number of encoded data slices is required to recover the data and the set of encoded data slices includes a pillar width number of encoded data slices. The method continues with the processing module storing the decode threshold number of encoded data slices in the local memories and outputting a remaining number of encoded data slices of the set of encoded data slices to the dispersed storage network (DSN) memory for storage therein.
