Abstract
Methods, apparatus, and other embodiments associated with doubly distributing erasure encoded data in a data storage system are described. One example apparatus includes a set of data storage devices and a set of logics that includes an encoding logic that generates an erasure encoded object that includes code-words, and chunks the code-words into code-word chunks, and a distribution logic that interleaves members of the set of code-word chunks into a plurality of records, and distributes the records across the data storage devices and within individual data storage devices. Example apparatus may include a read logic that reads the plurality of stored records from the data storage devices, and ignores read errors, and a repair logic that monitors the set of data storage devices, replaces or repairs failing data storage devices, generates replacement records, and stores the replacement records on a replacement data storage device.
