1. A method of retrieving encoded data slices in a dispersed storage network by selectively activating distributed storage units, comprising:
utilizing a processing unit, having a processor, to determine a number of distributed storage units of a plurality of storage units of the dispersed storage network that are active and available to retrieve encoded data slices of a data segment to recover the data segment, wherein data is initially divided into a set of separate data segments, including the data segment, and the encoded data slices of the data segment are stored in the plurality of distributed storage units, and wherein upon retrieval, only a threshold number of encoded data slices are required to recover the data segment, in which the threshold number of encoded data slices needed to recover the data segment being less than a total number of encoded data slices created and stored in the plurality of distributed storage units; determining, by use of the processing unit, which of the distributed storage units storing the encoded data slices of the data are active and available to retrieve the threshold number of encoded data slices of the data segment; determining, by use of the processing unit, which additional distributed storage units are to be made active to obtain the threshold number of the encoded data slices to retrieve, when less than the threshold number of the encoded data slices are available for retrieval, the determining based on an attribute associated with the distributed storage units; and utilizing the processing unit to selectively activate the additional distributed storage units to retrieve the threshold number of encoded data slices to recover the data segment. |
