Keynote Address III: Flash Math—FTL Algorithms and Performance

What makes one workload perform well on a particular SSD, and another poorly? How can we estimate performance from workload parameters? This talk will review recent results in analytic modeling of FTL performance and show how these results may be used not only to answer these questions, but to modify workloads and FTLs for better performance.

Peter Desnoyers is an associate professor at Northeastern University. He received his Ph.D. in Computer Science from the University of Massachusetts, Amherst in 2008. Prior to that he spent fifteen years as an engineer in storage and networking industries, at Apple, Motorola, and a number of start-ups, after receiving the BS and MS degrees in EECS from MIT in 1988. His research focuses on operating systems and storage, drawing on his experience to explore practical solutions to the problems of tomorrow's applications and devices.
