| 摘要 | A method includes dispersed storage error encoding, by a device of the dispersed storage network (DSN), a data segment of a data object into a set of encoded data slices. The method further includes sending, by the device, a set of write fan out with redundancy sharing requests to a set of storage units of the DSN. The method further includes, in response to the set of write fan out with redundancy sharing requests, storing, by the set of storage units, a number of copies of a decode threshold number of encoded data slices of the set of encoded data slices. The method further includes storing, by the set of storage units, a single copy of a redundancy number of encoded data slices of the set of encoded data slices. | ||||||
