Abstract
A distributed storage network receives a data object and determines a size of the data object. The network then determines whether the data object should be segmented into fixed size segments or variable sizes segments based upon some variable-length algorithm. If the fixed approach is selected, the data object is segmented into two or more fixed size segments with attached header information and the information is further processed using error coding dispersal storage functions within the network. If the variable approach is selected, the data object is segmented into two or more variable-sized segments with attached header information and the information is further processed using error coding dispersal storage functions within the network. Both the variable and fixed approaches enable storage of error-correctable data slices in a distributed storage manner.
