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.
