Abstract

See full text

A method for writing a set of encoded data slices to memory of a dispersed storage network (DSN) begins by a processing module identifying an encoded data slice of the set of encoded data slices for a redundant write operation to produce an identified encoded data slice. The method continues with the processing module generating a set of first write requests regarding the set of encoded data slices less the identified encoded data slice and generating a set of second write requests regarding the identified encoded data slice. The method continues with the processing module sending the set of first write requests to storage units of the DSN and sending the set of second write requests to a set of storage units of the DSN, where each storage unit of the set of storage units is sent a corresponding one of the set of second write requests.
