Echo is the Ceph-backed storage service developed at STFC to meet the UK’s data storage commitments to the Large Hadron Collider (LHC) experiments at CERN. The LHC experiments produce vast quantities of data which are stored across a worldwide grid of Tier 1 computer centres, including the UK Tier 1 centre at STFC’s Rutherford Appleton Laboratory. Echo uses erasure coding to protect the data it stores against disk failure while also reducing the storage space needed to implement such protection.
