Title:Main Title: dCache, from the LHC Petastore to a general purpose storage solution
Descriptions:Abstract: With the ignition of the Large Hadron Collider at CERN, End of November 2009, the largest physics experiment on earth will start to generate a stream of data, accumulating to about 15 Petabytes per year. Following a Tier model, this data will be replicated to various places around the globe. dCache is the storage system in charge of managing the largest share of this data outside CERN. It’s a data management technology designed for storing, retrieving, and managing huge amounts of data, distributed among a large number of heterogeneous server nodes, under a single virtual file system. The largest dCache installations are storing more than three Petabytes of data in a single instance on disk and on tape and they are expected to grow into the tenth Petabytes area by 2012. While dCache has been designed to fit the needs of High Energy Physics experiments, new challenges are waiting for large-scale storage solutions. Experiments in astronomy and in the area of extreme light sources will increase the required data rates and storage capacities by at least a factor of 10 and similarly important, they will force community storage systems to become compliant with industry standards. This publication will briefly describe how dCache fulfils the needs of LHC storage grid and is preparing itself for the upcoming challenges in other scientific disciplines.
