Reliability coding with reduced network traffic

A method comprising:

• generating a plurality of data fragments from data to enable reconstruction of the data from a subset of the plurality of data fragments;
• storing a first fragment of the plurality of data fragments at a first node in a network;
• generating a plurality of secondary fragments derived from the first fragment to enable reconstruction of the first fragment from a subset of the plurality of secondary fragments derived from the first fragment;
• storing the plurality of secondary fragments derived from the first fragment across a plurality of storage devices included within the first node;
• and
• reconstructing the portion of the data by at least reconstructing the first fragment from a subset of the plurality of secondary fragments derived from the first fragment while avoiding use of data durability coding implemented network-wide in the network.

A computer-readable storage media for storing computer-readable instructions that, when executed, configure processing circuitry of a storage system to perform operations comprising:

• generating a plurality of data fragments from data to enable reconstruction of at least a portion of the data from a subset of the plurality of data fragments;
• storing a first fragment of the plurality of data fragments at a first node in a network;
• generating a plurality of secondary fragments derived from the first fragment to enable reconstruction of the first fragment from a subset of the plurality of secondary fragments derived from the first fragment;
• storing the plurality of secondary fragments derived from the first fragment across a plurality of storage devices included within the first node;
• and
• reconstructing the portion of the data by at least reconstructing the first fragment from a subset of the plurality of secondary fragments derived from the first fragment while avoiding use of data durability coding implemented network-wide in the network.
