US 2022/0091937 A1 · Determining Segmentation Size In A Distributed Storage Network

Abstract

A method begins by receiving data to be distributedly stored in a storage network and continues by determining a decode threshold value for storage of the data, wherein the data is to be distributedly stored in the storage network. The method continues by determining a preferred encoded data slice size for storage of the data, where the preferred encoded data slice size is based on a minimum performance level requirement and based on the preferred encoded data slice size and the decode threshold value the method continues by determining a preferred segment size for the data. The method then continues by determining a segmentation scheme for the data based on the preferred segment size for the data and segmenting the data into a plurality of data segments in accordance with the segmentation scheme. The method then continues by determining dispersed error encoding parameters for encoding each data segment and encoding each data segment to produce a set of error encoded data slices.
