Terascala Rolls Out Open-Source Parallel File System Lustre 2.5.3 to Production Intelligent Storage Bridge

Terascala, Inc., a trademark of Dell, Inc., has released open-source parallel file system Lustre version 2.5.3 as part of its software stack that includes its TeraOS HPC storage management software.

Main features of this Lustre version include a HSM interface and a POSIX-compliant, client-side copy tool that uses this interface to move data between a Lustre file system and lower performance, low cost, scale-out storage.

An ongoing problem with Lustre and other parallel file systems is that end-to-end workflows can be inefficient, as there is a bandwidth gap between Lustre-based scratch storage and scale-out storage. Policy engines like RobinHood and Lustre client-side copy tools make it easier to define when and how to move data, but the actual data movement is limited by the slower scale-out storage. Terascala has solved this bandwidth disparity with its Intelligent Storage Bridge (ISB). The ISB is a available, clustered data mover that moves files in parallel up to 500Mb/s for each node in the ISB cluster. It replaces copy tools and has a command line interface for workflow integration. It is already being used by customers to reduce workflow execution from days to hours.

“Dell is pleased to continue growing our HPC Storage Solution (HSS) for the enterprise and provide Lustre 2.5 with Terascala,” said Neil Klosterman, HPC product manager, Dell enterprise solutions group. “These solutions enable customer innovation by delivering the latest Lustre functionality and shortest time to insight.“

“This new Lustre release allows our customers to transparently interact with scale-out storage from their high performance storage infrastructure,” noted Steve Butler, CEO, Terascala. “Our focus on the end-to-end solution allows customers to get the most return on their HPC investment.“
