Project Summary
EOS is a software solution that aims to provide fast and reliable multi-PB disk-only storage technology for both LHC and non-LHC use-cases at CERN. The core of the implementation is the XRootD framework which provides feature-rich remote access protocol. The storage system is running on commodity hardware with disks in JBOD configuration. It is written mostly in C/C++, with some of the extra modules in Python. Files can be accessed via native XRootD protocol, a POSIX-like FUSE client or HTTP(S) & WebDav protocols.
