The Scalla software suite provides two fundamental building blocks: an xrootd server for low latency high bandwidth data access and an olbd server for building scalable xrootd clusters. This paper describes the architecture, how low latency is achieved, and the scaling opportunities the software allows. Actual performance measurements are presented and(More)
Scientific advances depend increasingly on agility in the analysis of data, along with access to massive computation. The PetaCache project addresses the data-access issue by recognizing that the future for intense, non-sequential, data access must be based on low latency solid-state storage. The PetaCache architecture aims at a minimum unit cost, highly(More)
