Data storage technologies for LHC
Les Robertson · CERN Document Server (European Organization for Nuclear Research) · 2000
The paper introduces some of the technologies that could be used for storing and managing the many PetaBytes of data that will be collected and processed at the Large Hadron Collider (LHC) accelerator, which is scheduled to begin operation at CERN in 2005.The state of the art of the current mainline hardware technologies is described, with a discussion of the likely evolution during the next five years.This paper is a summary of the material provided in the lecture notes, which include more detailed descriptions of some of the fundamental technologies and costs issues.The notes also introduce some more exotic techniques, and discuss the storage capacity and performance requirements of the experiments that will use the LHC accelerator.
