Garth Gibson received his Ph.D. in Computer Science from the University of California at Berkeley in 1991. While at Berkeley he co-wrote the seminal “Berkeley RAID paper.” He joined the faculty at Carnegie Mellon University (CMU) in 1991 where he founded the Parallel Data Laboratory (, one of the country’s premier academic storage system research labs. He also founded the Network-Attached Storage Device (NASD) working group of the National Storage Industry Consortium (NSIC) and led storage systems research in the Data Storage Systems Center (DSSC), one of the largest academic magnetic storage technology research labs. Garth was a member of the founding technical council of the Storage networking Industry Association (SNIA) and the founding steering committee of USENIX's File and Storage Technology (FAST) conference. ANSI T10's standard for Object-based Storage Devices (OSD), and its sister SNIA OSD technical working group, were seeded by Gibson's CMU and NSIC/NASD research.

Garth’s contributions to computer storage have been recognized by the prestigious 1999 IEEE Reynold B. Johnson Information Storage Award for outstanding contributions in the field of information storage, inclusion in the Hall of Fame of the ACM Special Interest Group for Operating Systems in 2011, and the 2012 Jean-Claude Laprie Award in Dependable Computing from the IFIP WG 10.4 on Dependable Computing and Fault Tolerance.
