1. A method comprises:

  • receiving a data storage request that includes metadata and data;

    determining a base-line set of error coding dispersal storage function parameters based on the metadata;

    identifying candidate dispersed storage (DS) units based on the base-line set of error coding dispersal storage function parameters;

    selecting DS units of the candidate DS units based on the metadata to produce selected DS units;

    dispersed storage error encoding the data in accordance with at least a representation of the base-line set of error coding dispersal storage function parameters to produce a set of encoded data slices; and

    sending the set of encoded data slices to the selected DS units for storage therein.
