中文摘要：
满足BES计算庞大的I/O访问需求,需要先进的存储体系结构和合理的配置。描述了基于Lustre的BES集群存储系统的设计和实现。介绍了Lustre的组成和作为PetaScale级分布式文件系统的设计特点,描述了BES集群存储系统的具体实现,分析了系统的负载特征。分析了硬件级、操作系统级和文件系统级的性能影响因素,并针对关键因素的不同配置做了测试,提出性能优化方案。
英文摘要：
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.
