Prague Tier-2 storage experience

Main computing and storage facilities for LHC computing in the Czech Republic are situated in Prague Tier-2 site. We participate in grid activities since the beginning of European Data Grid. The recent years were significant in the growth of our storage capacities. In this article we present the decisions in storage solutions, comparison of configurations of the hardware and performance tuning of the software. Our storage facilities vary from enterprise-level SAN infrastructure to in-house built cheap storage servers. We present a comparison of these solutions from the performance, configuration, management and monitoring point of view.
