1. A maintenance free storage container comprises: a plurality of storage servers, wherein a storage server of the plurality storage servers includes a plurality of storage devices and a server control module, wherein the server control module manages storage and retrieval of data from the plurality of storage devices, and wherein the maintenance free storage container allows for multiple storage servers of the plurality of storage servers to be in a failure mode without replacement and allows for multiple storage devices of the plurality of storage devices of one or more the plurality of storage servers to be in the failure mode without replacement; and a container controller operable to: establish, based on vault registry information, a first mapping of a plurality of virtual storage servers of a vault to at least some of the plurality of storage servers based on storage server utilization information and storage server failure information; facilitate storage of encoded data slices in the at least some of the plurality of storage servers in accordance with the first mapping; when, in light of data storage adjustment criteria of the vault registry information, evaluation of the storage server utilization information and the storage server failure information triggers an adjustment of the first mapping, adjust the first mapping in accordance with the data storage adjustment criteria to produce a second mapping the plurality of virtual storage servers of the vault to the at least some of the plurality of storage servers; facilitate storage of new encoded data slices in the at least some of the plurality of storage servers based on the second mapping; and facilitate modification of storage of the encoded data slices stored in accordance with the first mapping based on the data storage adjustment criteria.
