Abstract: Each data file of a distributed file system is identified by a corresponding globally-unique object identifier that is independent of any attribute of the data file. A node in the distributed file system has a file system that includes a plurality of directory entries, where each directory entry has a file name field, an attributes field, and an object identifier field configured for specifying a globally-unique object identifier. The globally-unique object identifier is universally reachable by any node of the distributed file system and uniquely identifies the data file, enabling the data file to be universally identifiable by any node based on the corresponding object identifier. The data file can be stored independently of a device file system based on providing a resolution between the data file name and its object identifier, followed by a resolution between the object identifier and a selected location for the data file.

Abstract translation: 分布式文件系统的每个数据文件由独立于数据文件的任何属性的相应的全局唯一对象标识符来标识。 分布式文件系统中的节点具有包括多个目录条目的文件系统，其中每个目录条目具有文件名字段，属性字段和配置用于指定全局唯一对象标识符的对象标识符字段。 全局唯一的对象标识符通常由分布式文件系统的任何节点可访问，并且唯一地标识数据文件，使数据文件能够基于相应的对象标识符被任何节点普遍识别。 数据文件可以独立于设备文件系统存储，基于在数据文件名称与其对象标识符之间提供分辨率，随后在对象标识符与数据文件的选定位置之间进行分辨率。
