During the past 35 years, Moshe Yanai has developed innovative data storage solutions to overcome the gap between growing amounts of data and the mechanical limitations of disk drives. Considered by many to be the most influential leader in the data storage industry, Mr. Yanai’s architectures changed how companies store and use data. He developed and cultivated the Symmetrix storage array while at EMC Corp., Hopkinton, Mass., in the late 1980s. Symmetrix allows multiple servers to connect to the same storage device using a small computer system interface (SCSI), and it enabled the large relational databases common to the business world today. In 2003, Mr. Yanai founded XIV, Ltd., and developed the first truly scalable grid storage system, providing a lower-cost, highly reliable and easy to manage storage solution. The system quickly became popular with major banks, Internet service providers and telecommunication companies. IBM Corp. acquired XIV and the grid system in December 2007.
An IEEE Member, Mr. Yanai is currently an IBM Fellow at IBM Corp., Waltham, Mass.

Marshall Kirk McKusick is best known for the design, architecture and implementation of the 4.2 Berkeley Software Distribution (4.2BSD) Fast File System (FFS), which is still in wide use today in most variants of the UNIX operating system. Dr. McKusick introduced rotational optimization, multiple block sizes with fragments, cylinder clustering and optimized block location to improve performance, and his system enhanced reliability by replicating critical data structures and placing them strategically on the disk to make them resilient to failures. The FFS architecture emphasized all these attributes which enabled computers to handle parallel tasks and simultaneous users.
Dr. McKusick’s long-standing influence can be seen in his willingness to share and disseminate his research. He has made available production quality code through FreeBSD—a free operating system compatible with UNIX—and he has mentored and provided assistance to the next generation of file system developers and creators of other systems, such as Linux.
An IEEE Member, Dr. McKusick is an independent consultant residing in Berkeley, California.

David Hitz and James Lau’s significant contributions to networked data storage have helped fuel the growth of the billion-dollar global data storage market. Based on the belief that data should be constantly moving, or “networked” to facilitate its management, Mr. Hitz and Mr. Lau devised the Write Anywhere File-System Layout (WAFL), which has revolutionized storage as well as the sharing and protection of information assets throughout an organization. The WAFL-based network appliance, a dedicated, stackable network storage device, has changed the way information is stored at the enterprise level, supplanting general-purpose servers at many enterprise organizations. It is currently in use at an estimated 90 percent of Fortune 500 companies.
Mr. Hitz and Mr. Lau co-founded Network Appliance, Inc. in 1992, which has grown into a Fortune 1000 company with annual sales of nearly of $3 billion.
Mr. Hitz earned his bachelor’s degree in Electrical Engineering and Computer Science from Princeton University. Mr. Lau holds a bachelor’s degree in Computer Science and Applied Mathematics from the University of California, Berkeley, and a master’s degree in Computer Engineering from Stanford University, California.

Dr. Jaishankar (Jai) M. Menon has been the driving force for advancing Redundant Array of Independent Disks (RAID) storage systems as the high-performance, high-reliability solution for server-based computers.
Currently vice president and chief technologist of storage systems architecture in the IBM Systems and Technology Group in San Jose, California, Dr. Menon has influenced the design of every IBM disk array product since the 1980s. His work propelled the transition from single large disks to RAID-based designs that allow for immediate data availability or the recovery of lost data, as well as for selected levels of data redundancy. He also created techniques for RAID arrays, including techniques to combine caching with RAID to significantly improve performance and the ability to add devices to an array while in use, thus hastening RAID’s adoption as the standard storage technology. In addition, he led the development of emulation of older mainframe devices and their protocols using cached RAID designs, improving storage reliability and lowering costs for the existing installed base.
His leadership fostered the strong growth of RAID array storage products, which now support all forms of server-based computing and generate nearly $20 billion in annual revenues. Dr. Menon is responsible for major advances in storage networking and attaching logical storage devices to servers through networks, including technologies which reduce the need to exchange data between servers. This saved as much as 30 percent of server capacity. In addition, he instigated the IBM development of LAN-free and server-free backups that have dramatically improved data backup and restore times.
Dr. Menon has authored 31 papers and 47 technical reports on RAID and storage systems, holds 50 U.S. patents for storage technology and has 11 additional applications with the U.S. Patent Office. He is a contributing author to three books on database and storage systems. An IEEE Fellow, he is the recipient of the W. Wallace McDowell Award of the IEEE Computer Society.
He holds a bachelor’s degree in electronics and communications engineering from the Indian Institute of Technology in Madras and master’s and doctoral degrees from Ohio State University in Columbus, both in computers and information science.J
