Enabling Lustre WAN for production use on the TeraGrid
Joshua Walgenbach, Stephen C. Simms, Kit Westneat, Justin P. Miller · 2010
The Indiana University Data Capacitor wide area Lustre file system provides over 350 TB of short- to mid-term storage of large research data sets. It spans multiple geographically distributed compute, storage, and visualization resources. In order to effectively harness the power of these resources from various institutions, it has been necessary to develop software to keep ownership and permission data consistent across many client mounts. This paper describes the Data Capacitor's Lustre WAN service and the history, development, and implementation of IU's UID mapping scheme that enables Lustre WAN on the TeraGrid.
