Glamour: A Wide-Area Filesystem Middleware Using NFSv4

In this paper we describe the design and implementation of Glamour, a federated filesystem layer that enables clients to seamlessly navigate data that is spread across multiple heterogeneous widely distributed file servers. Glamour is not a globally distributed filesystem. Instead, it enables a set of loosely coupled file servers to behave as one. It provides the common enterprise-wide namespace and data management operations as a wide-area distributed filesystem would, while relying completely on standard off-the-shelf clients, filesystems and client-server protocols. Glamour provides data management with flexible granularity and supports transparent replication and data migration. Using our testbed, we demonstrate the various features of Glamour and report on overheads.
