READ-OTHER PROTOCOL FOR MAINTAINING PARITY COHERENCY IN A WRITE-BACK DISTRIBUTED REDUNDANCY DATA STORAGE SYSTEM

Strategic Insights -

A new patent was published by the World Intellectual Property Organization, describing an innovative protocol for maintaining data storage reliability in distributed redundancy data storage systems. The READ-OTHER PROTOCOL is designed to ensure parity coherency across multiple nodes in a write-back distributed data storage system. This technology has significant implications for data storage and management, particularly in applications where high reliability and data integrity are crucial.

Key Takeaways:

  • The READ-OTHER PROTOCOL is a novel method for maintaining parity coherency in a write-back distributed data storage system, ensuring data storage reliability.
  • Each node in the system comprises a processor and an array of failure-independent data storage devices, storing information as a set of stripes, each including data and parity strips.
  • The primary data node drives parity coherency with corresponding parity nodes, independently of other data nodes, keeping relevant parity strips for the primary data node coherent.
  • A parity value is determined based on data other than the difference between new and existing data, with a new parity value based on new data and dependent data.
  • This protocol enables efficient data storage and management, particularly in applications requiring high data reliability.
  • The READ-OTHER PROTOCOL is applicable to various industries, including cloud computing, enterprise storage, and data centers.

Statistics:

  • The patent was filed on February 22, 2011, under Application No. PCT/EP2011/052572.
