Abstract:
Cloud computing promises large-scale and seamless ac- cess to vast quantities of data across the globe. Appli- cations will demand the reliability, consistency, and per- formance of a traditional cluster file system regardless of the physical distance between data centers.
Panache is a scalable, high-performance, clustered file system cache for parallel data-intensive applications that require wide area file access. Panache is the first file system cache to exploit parallelism in every aspect of its design—parallel applications can access and update the cache from multiple nodes while data and metadata is pulled into and pushed out of the cache in parallel. Data is cached and updated using pNFS, which performs parallel I/O between clients and servers, eliminating the single-server bottleneck of vanilla client-server file ac- cess protocols. Furthermore, Panache shields applica- tions from fluctuating WAN latencies and outages and is easy to deploy as it relies on open standards for high- performance file serving and does not require any propri- etary hardware or software to be installed at the remote cluster.
In this paper, we present the overall design and imple- mentation of Panache and evaluate its key features with multiple workloads across local and wide area networks.
