Scalable Petascale Storage for HEP using Lustre
C J Walker, D. Traynor, Andrew J. Martin · Journal of Physics Conference Series · 2012
We have deployed a 1 PB clustered filesystem for High Energy Physics. The use of commodity storage arrays and bonded ethernet interconnects makes the array cost effective, whilst providing high bandwidth to the storage. The filesystem is a POSIX filesytem, presented to the Grid using the StoRM Storage Resource Manager (SRM). We describe an upgrade to 10 Gbit/s networking and we present benchmarks demonstrating the performance and scalability of the filesystem.
