MBFS: Designing High-performance File Systems via efficient use of Memory

Date: August 15, 1996

Abstract: File systems have historically suffered from high access latencies that, in recent years, has become even worse relative to processor speeds. To complicate matters, emerging technologies such as wireless computing, telecommuting environments, and even CD-ROMs exhibit higher latencies than conventional file systems.

This talk will describe a file system design that hides latency by moving data through the system in an attempt to keep pace with the processor's demand for data. We present predictive caching and prefetching techniques that reduce read latencies. We also present a cost-effective reliable memory-based storage system that reduces write latency. Results from a simulation model and a prototype implementation demonstrate the potential benefits of the MBFS design.
