Method and system of multi-fold data protection for high-density storage appliance with improved availability and robustness

摘要

A first set of data is encoded using a first code to obtain a first-code codeword which includes the first set of data and first-code parity information. The first set of data is stored on a plurality of drives, wherein the first set of data is distributed amongst the plurality of drives. A second set of data is encoded using a second code to obtain a second-code codeword which includes the second set of data and second-code parity information. The second-code codeword is stored on the plurality of drives, wherein the second set of data and second-code parity information are distributed amongst the plurality of drives.
