Abstract

A method for execution by a storage unit in a directory-less storage network includes receiving a read request regarding a data segment of a data object, where the data segment was error encoded into a set of encoded data slices. The method further includes outputting a read response regarding an encoded data slice of the set of encoded data slices that is stored by the storage unit. The method further includes identifying an other storage unit of the directory-less storage network to which the read request is to be forwarded, where the identifying the other storage unit includes one or more of accessing a table of localized mapping regarding one or more neighboring storage units to identify the other storage unit, and receiving a message from a network management unit. The method further includes forwarding the read request to the other storage unit.
