Success Story Networking Abstraction Layer
The Customer - LustreLustre is a cluster file system initiative supported by the US Department of Defense & the US national defense labs to manage the peta-bytes of data they generate.
The Challenge - Lustre runs over many different networks and the cluster file system has a specific network access API, that needs to be implemented on each network type. Key issue was performance in terms of throughput and low CPU utilization.
The Solutions - Calsoft designed and implemented a network abstraction layer for Lustre: a cluster file system over Alacritech's TOE card.
