A BES cluster storage system based on Lustre

The huge storage requirement of BES computing calls for advanced storage architecture and reasonable configuration. It describes a BES storage system based on Lustre. The components of Lustre and its advantages as a PetaScale storage architecture are introduced. The implementation of target system and the characteristic of workload are described. It analysis performance factors on hardware level, operation system level and file system level, provides test results for different performance parameters, and at last put forward solutions to optimize I/O performance on the target system.
