Quantum Assigned Patent
Cloud-based SSD with dynamically variable ECC system
By Francis Pelletier | September 5, 2023 at 2:00 pmQuantum Corporation, San Jose, CA, has been assigned a patent (11722158) developed by Saliba, George, Boulder, CO, for “cloud-based solid state device (SSD) with dynamically variable error correcting code (ECC) system.”
The abstract of the patent published by the U.S. Patent and Trademark Office states: ”Example apparatus and methods control an error correcting code (ECC) approach for data stored on a solid state device (SSD). The control may be based on a property (e.g., reliability, error state, speed) of an SSD, or on an attribute of the data to be stored. Approaches including a hybrid rateless Reed-Solomon ECC approach or a fountain code ECC approach may be selected. Example apparatus and methods may store padded portions of an ECC at different locations in an SSD. Example apparatus and methods may dynamically generate performance test data about the SSD, and dynamically control the ECC approach based on the performance test data. Different types or numbers of ECC may be produced, stored, and provided for different data sets stored at different SSDs or at different physical locations within an SSD. The SSD may be local, or may be part of a cloud-based storage system.”
The patent application was filed on 2022-01-03 (17/567603).
