橡树岭国家实验室（ORNL）的橡树岭领导力计算设施（OLCF）在部署世界上最快的超级计算机以实现开放科学方面有着悠久的历史。在2008年部署时，Spider文件系统的格式化容量为10 PB，持续传输速度为240 GB/s，使其成为世界上最快的Lustre文件系统。然而，Titan（一个27 PFLOPS的Cray XK 7系统）的加入，沿着其他OLCF计算资源，极大地增加了I/O需求，超出了现有Spider并行文件系统的能力。下一代Spider Lustre文件系统旨在为OLCF的开放科学用户提供32 PB的容量，总传输速率为1 TB/s。本文详细介绍了下一代Spider文件系统的体系结构、设计选择和配置
The Oak Ridge Leadership Computing Facility (OLCF) at Oak Ridge National Laboratory (ORNL) has a long history of deploying the world’s fastest supercomputers to enable open science. At the time it was deployed in 2008, the Spider file system had a formatted capacity of 10 PB and sustained transfer speeds of 240 GB/s which made it the fastest Lustre file system in the world. However, the addition of Titan, a 27 PFLOPS Cray XK7 system, along with other OLCF computational resources, has radically increased the I/O demand beyond the capabilities of the existing Spider parallel file system. The next-generation Spider Lustre file system is designed to provide 32 PB of capacity to open science users at OLCF, at an aggregate transfer rate of 1 TB/s. This paper details the architecture, design choices, and configuration of the next-generation Spider file system
