ParaSwift - File I/O Trace Modeling for the Future

Explore a 16-minute conference talk from USENIX LISA14 that introduces ParaSwift, an innovative algorithm for modeling file I/O traces. Delve into the challenges of managing large-scale traces and the growing importance of trace modeling in system design and testing. Discover how ParaSwift addresses the complexities of modeling file traces, including meta-data operations and stateful NFS operation semantics. Learn about the unified framework that enables modeling and replaying of both NFS and SAN workloads. Examine the efficient resource consumption approach using Bloom Filter-based sampling techniques. Gain insights into the algorithm's verification process using real customer traces and its low modeling error rates.
