profile


Steve Hetzler is an IBM Fellow and manager of Cloud Data Architecture at IBM's Almaden Research Center (San Jose, Calif.). He has spent over 25 years in data storage research and development.

Most recently, he and his team are developing highly reliable, low cost storage system architectures for cloud like applications, and novel storage systems for tackling the big data explosion. The combined hardware/software team is currently working on cloud storage projects based on new erasure codes invented here. The team works on many different technologies, from solid state storage to robotics.

Steve developed both the Touch Rate performance metric and Chasm Analysis, a methodology for analyzing market potential for storage technologies using economic data. Previously, he initiated work on the IP storage protocol that is now known as iSCSI, which he later named. The group under his management developed the concept from an idea to the first specification before joining with Cisco to bring the work to the Internet Engineering Task Force. His team developed the first working iSCSI demonstrations. Steve has a blog on data storage at https://smorgastor.drhetzler.com, which while not updated frequently, has a quite a bit of data on flash storage.

Steve has been issued over 70 patents for inventions covering a wide range of topics including data storage systems and architecture, optics, error correction coding and power management. His most notable patents include split-data field recording and the No-ID(TM) headerless sector format, which have been used by all magnetic hard-disk-drive manufacturers for a number of years. He joined IBM Research in 1985 and was named an IBM Fellow in 1998. He obtained his Ph.D. in Applied Physics from the California Institute of Technology.
