Steven R. Hetzler is an IBM Fellow at IBM's Almaden Research Center (San Jose, Calif.), where he manages the Advanced File Architecture group.
He is currently focusing on new architectures for creating highly fault-tolerant storage systems as well as architectures for iSCSI data storage systems. iSCSI is a protocol for managing storage over IP networks that he initiated within IBM Research and also named. His group developed the first working iSCSI demonstrations, including the first direct network-attached DVD movie multiplex, and was active in developing iSCSI into an industry standard.
A prolific inventor, Hetzler has received 25 patents for inventions in a wide range of areas, including data storage systems and architecture, optics, error correction coding and power management. His most notable patents include split-data field recording (issued in 1993) and the No-ID(TM) headerless sector format (issued in 1995), which have been used by nearly all magnetic hard disk drive manufacturers for a number of years. He also pioneered the first adaptive power technology for disk drives, which is also widely used in mobile computers.
Hetzler has received numerous IBM awards for his work, including three Corporate Awards, and a Corporate Environmental Affairs Excellence Award. He is a member of the American Physical Society, a senior member of the Institute of Electronics and Electrical Engineers and a member of the IBM Academy of Technology.
A native of Red Wing, Minnesota, Hetzler received his Bachelor of Arts in Physics from Carleton College in Northfield, Minnesota in 1980. He received his Masters and Ph.D. degrees in Applied Physics from the California Institute of Technology in Pasadena, California, in 1982 and 1986, respectively. He joined IBM Research in November 1985 and was named an IBM Fellow in 1998.
