Adjusting a dispersal parameter of dispersedly stored data

摘要

A method begins by a processing module storing data files utilizing a dispersed storage error coding function that includes a pillar width parameter and a decode threshold parameter. The method continues with the processing module determining whether to adjust redundancy of the dispersed storage error coding function based on performance of the DSN. When the redundancy of the dispersed storage error coding function is to be adjusted, changing a ratio between the pillar width parameter and the decode threshold parameter and adjusting storage of one or more sets of the plurality of sets of encoded data slices based on the changing of the ratio.

1. A method for execution by a computing device, the method comprises:
storing data files utilizing a dispersed storage error coding function, wherein a data file of the data files is encoded using the dispersed storage error coding function to produce a plurality of sets of encoded data slices, wherein the plurality of sets of encoded data slices is stored in memory of a dispersed storage network (DSN), and wherein the dispersed storage error coding function includes a pillar width parameter and a decode threshold parameter; determining whether to adjust redundancy of the dispersed storage error coding function based on performance of the DSN; when the redundancy of the dispersed storage error coding function is to be adjusted, changing a ratio between the pillar width parameter and the decode threshold parameter; and adjusting storage of one or more sets of the plurality of sets of encoded data slices based on the changing of the ratio.
