TITLE:
Scalable Randomization for Dynamic Data Storage
ABSTRACT:
A scalable storage architecture is important in systems that store and
access growing data sets. Storage scalability enables the increase or
decrease of the overall storage bandwidth and capacity as needed. A truly
scalable system should accept any amount of growth in data size without
hindering system
performance.
This talk will describe a scalable randomization algorithm to enable an efficient, dynamically expandable storage system. While previous techniques can support a balanced load and quick data retrieval, they fail in efficiency of data relocation during scaling. Other techniques provide minimal relocation, but do not offer incremental scaling. The challenge is to find a scaling solution that maintains a balanced load and provides fast data access without costly data reorganization. Finally, advances in technology inevitably result in the replacement of old homogeneous storage devices with new heterogeneous devices; thus, heterogeneous scaling is also supported.
BIO:
Didi Yao received his Ph.D. and M.S. in Computer Science in 2003 and 2000,
respectively, from the University of Southern California (USC). He received
his B.S. in Electrical Engineering and Computer Science in 1997 from the
University of California, Berkeley. His research interests include scalable
storage architectures, multimedia servers, and distributed systems. At
USC, he co-architected a distributed, continuous media server called Yima,
implemented its storage subsystem, and researched several storage scaling
techniques. He was a co-founder of the Graduate Tech Alliance at USC's
Marshall School of Business, which actively assisted in commercializing
USC technologies. Prior to USC, he was a bioinformatics researcher for
the Berkeley Drosophila Genome Project. Dr. Yao is a recipient of the
Intel Ph.D. Fellowship.
