This document describes the architecture of the LHCb storage system, and discusses the key criteria which formed the basis of the evaluation of the system. The configuration of the current solution and its capabilities are also described, accompanied by performance figures.
LHCb is implementing event-building over a gigabit Ethernet switched network. One component of the data acquisition network is a gateway PC which role is to gather data packets from data sources, rebuild events and forward them to computing nodes for trigger algorithms. In this article, we concentrate on the implementation of this component as a software running on a Linux system. We describe in details...
