Abstract
We have developed remote data access for large volumes of data over the Wide Area Network based on the Lustre filesystem and Kerberos authentication for security. In this paper we explore a prototype for two-step data access from worker nodes at Florida Tier3 centers, located behind a firewall and using a private network, to data hosted on the Lustre filesystem at the University of Florida CMS Tier2 center. At the Tier3 center we use a client which mounts securely the Lustre filesystem and hosts an XrootD server. The worker nodes access the data from the Tier3 client using POSIX compliant tools via the XrootD-fs filesystem. We perform scalability tests with up to 200 jobs running in parallel on the Tier3 worker nodes.
