Abstract

A method includes segmenting a data object into data segments based on segmenting information. For a first data segment, the method further includes dispersed storage error encoding the first data segment. The method further includes identifying a first set of storage units from a pool of storage units. The method further includes issuing a first set of write requests to the first set of storage units. The method further includes receiving write responses from the first set of storage units. The method further includes, when a write threshold number of favorable write responses have been received, generating a first DSN addresses for encode data slices based on Internet addresses of storage units that provided the favorable write responses and based on the temporary slice names of the encoded data slices. The method further includes storing an association of the first DSN addresses and the first encode data slices.

First claim

What is claimed is:

1. A method for execution by a computing device of a dispersed storage network (DSN), the method comprises:
segmenting a data object into a plurality of data segments based on segmenting information; and
for a first data segment of the plurality of data segments:
dispersed storage error encoding the first data segment based on dispersed storage error encoding parameters to produce a first set of encoded data slices;
identifying a first set of storage units…
