Method and apparatus for operating a data storage system

A method for operating a data storage system comprising a plurality of storage devices and a plurality of controllers respectively corresponding to the plurality of storage devices, the method comprising:

• receiving a request for data;
• determining a data stripe that includes the requested data, wherein the data strip includes a plurality of code words acquired respectively from the plurality of storage devices;
• instructing the plurality of controllers to perform a decoding of the plurality of code words of the determined data stripe, wherein the decoding of the plurality of code words includes a linear block code error handling operation that includes a multiplication of each of the plurality of code words with a matrix;
• determining, based on error status information generated based on the multiplications, an error handling operation on the data stripe to correct one or more code words of the plurality of code words of the data stripe;
• and
• generating the requested data based on the corrected one or more code words.

A method for operating a data storage system, the method comprising:

• receiving, by a storage device of the data storage system, data to be stored;
• encoding the received data into a plurality of code words for error correction, wherein encoding the received data into the plurality of code words includes encoding the received data in accordance with a linear block code;
• obtaining a plurality of data stripes from the plurality of code words, wherein each of the plurality of data stripes includes a corresponding one of the plurality of code words and one or more other code words from one or more storage devices other than the storage device;
• encoding the plurality of data stripes for error correction;
• and
• storing the plurality of encoded data stripes in the data storage system.

A non-transitory computer-readable medium storing instructions that are executable by one or more processors of an apparatus to perform a method for operating a data storage system, the method comprising:

• receiving a request for data;
• determining a data stripe that includes the requested data, wherein the data stripe includes a plurality of code words acquired respectively from the plurality of storage devices;
• instructing a plurality of controllers to respectively perform a decoding of the plurality of code words of the determined data stripe, wherein the decoding of the plurality of code words includes a linear block code error handling operation that includes a multiplication of each of the plurality of code words with a matrix;
• and
• determining, based on error status information generated based on the multiplications, an error handling operation on the data stripe to correct one or more code words of the plurality of code words of the data stripe;
• and
• generating the requested data based on the corrected one or more code words.
