XtreemFS 是一个为互联网存储系统设计的分布式文件系统。-It allows you to mount an XtreemFS volume from anywhere, given the right permissions. It includes support for POSIX ACLs and extended attributes (xattrs). As an object-based parallel file system, it allows you to stripe files over multiple storage servers for high-performance parallel access with file-specific striping pattern. It can be integrated in X.509-based security infrastructures. When deployed as part of an XtreemOS Grid installation, you will benefit from its transparent integration with the XtreemOS Virtual Organization (VO) infrastructure in the form of dynamic user mappings and automatic mounting of home volumes。
