RAL Stratum 1 CVMFS Replica Service

Architecture

Basic architecture has cvmfs/web server which pulls copies of repositories and serves them by http.

A pair of reverse proxy squids to make this both more performant and more resilient.

The "cernvmfs.gridpp.rl.ac.uk" address is located on the reverese proxies.

Replication

LHC repositories hosted at CERN are replicated every hour at 10 minutes past the hour, apart from lhcb-condb which is replicated every 10 minutes.

non-LHC repositories hosted at RAL are replicated every hour.
