摘要

带有扩展的AFS (Andrew File System)构成了在匹兹堡超级计算中心(PSC)实现的分布式大容量存储系统的基础。AFS提供了对来自各种UNIX平台的通用文件名空间的透明、本地缓存和安全访问。PSC正在扩展标准AFS产品,以提供许多在超级计算环境中有用的特性。这些扩展包括将AFS客户端代码移植到Unicos,以及支持高性能磁盘阵列和归档服务器(如Common File System、UniTree和机器人NSF系统)的修改。这些特性是通过为AFS服务器开发通用的多驻留扩展来实现的。正在制定数据迁移战略。PSC扩展不需要更改用户的AFS客户端代码。>

An AFS-based mass storage system at the Pittsburgh Supercomputing Center
The AFS (Andrew File System) with extensions forms the basis of the distributed mass storage system being implemented at the Pittsburgh Supercomputing Center (PSC). AFS offers transparent, locally cached, secure access to a universal file name space from a wide variety of UNIX platforms. The PSC is extending the standard AFS offering to provide a number of features that are useful in a supercomputing environment. The extensions include a port of AFS client code to Unicos and modifications to support high-performance disk arrays and archival servers such as the Common File System, UniTree, and robotic NSF systems. These features are implemented by the development of generalized multiple residency extensions for AFS servers. Data migration strategies are being developed. The PSC extensions require no changes to the user's AFS client code. >
