xrootd

An eXtended Root Daemon

The XROOTD project gives access to data repositories. The typical usage is to give access to file-based ones. It is based on a scalable architecture, a communication protocol, and a set of plugins and tools based on those. The ability to configure it and to make it scale (for size and performance) allows the deployment of data access clusters of virtually any size, which can include sophisticated features, like authentication/authorization, integrations with other systems, WAN data distribution, etc. The XRootD software framework is a generic suite for data access, which can serve natively any kind of data, organized as a hierarchical filesystem-like namespace, based on the concept of a directory.
