Description

This talk reexamines the rules-of-thumb for the design of data storage systems. Briefly, it looks at storage, processing, and networking costs, ratios, and trends with a particular focus on performance and price/performance. Amdahl's ratio laws for system design need only slight revision after 35 years - the major change being the increased use of RAM. An analysis also indicates storage should be used to cache both database and web data to save disk bandwidth, network bandwidth, and people's time. Surprisingly, the 5-minute rule for disk caching becomes a cache-everything rule for web caching. Biography: Jim Gray is part of Microsoft's research group. His work focuses on databases and transaction processing. Jim is active in the research community, is an ACM, NAE, NAS, and AAAS Fellow, and received the ACM Turing Award for his work on transaction processing. He is also a member of the PITAC, and edits of a book series of books on data management.
