Title: James A. O’Conner: Data Storage Reliability Inventor

Introduction

James A. O’Conner is an inventor associated with Ulster Park, New York, and International Business Machines Corporation. His work includes inventions for detecting and correcting dropped-write errors in data storage systems. He is credited with 3 patents.

Latest Patents

O’Conner’s listed patents, “Detection and correction of dropped write errors in a data storage system” and “Detection and correction of dropped write errors in a data storage system,” describe methods for identifying and addressing dropped writes in storage systems such as RAID arrays.

The methods write data and a checksum to a storage device, then classify the data as “new data, unconfirmed.” The system periodically checks the data for a dropped write. If one is detected, it marks the data as having a confirmed single dropped write and can correct the error. If no dropped write is found, the data is marked “confirmed good.” Data changed through a read-modified-write before the check is classified as “unquantifiable.”
