1. A maintenance free storage container comprises: a container housing; a plurality of storage servers mechanically mounted in the container housing and physically inaccessible when the container housing is substantially sealed; and a container controller mechanically mounted in the container housing, wherein the container controller includes: an external network interface; an internal network interface for operable coupling to the plurality of storage servers; and a processing module that is operably coupled to the external network interface and the internal network interface, wherein the processing module is operable to: maintain virtual storage server to physical storage server mapping information; maintain storage server failure information; dispersed storage error encode the virtual storage server to physical storage server mapping information to produce one or more sets of encoded mapping slices; send, via the external network interface, the one or more sets of encoded mapping slices for dispersed storage outside of the maintenance free storage container; dispersed storage error encode the storage server failure information to produce one or more sets of encoded failure data slices; and send, via the external network interface, the one or more sets of encoded failure data slices for dispersed storage outside of the maintenance free storage container.
