This technical report shows the behaviour of Lustre storage subsystem for different applications. Lustre is a scalable file subsystem and let the final user to control the way her files are stored. CESGA has 694,5TB usable in Finis Terrae II supercomputer, and the Infiniband network achieves better results than DAS storage. This report is intended to be a study of performance with different storage subsystems in a real supercomputer with real typical applications. The file size, the number of OSTs used or the pieces in which file is divided are a few of the parameters used to measure the performance of Lustre and try to obtain the best parameters to use efficiently this storage subsystem.
