Pangaea: a structural overview

This section overviews the structure of a server and the major data structures it maintains. Pangaea's design follows a symmetrically distributed approach. A Pangaea server handles file-access requests from users. We assume that a user uses a single server during a log-in session (lasting, say, a few hours), so that on-demand replication improves file-access latency; the user may move between servers over time. Each server maintains local hard disks, used to store replicas of files and directories. Servers interact with each other in a peer-to-peer fashion to provide a unified file-system.
