Abstract: Techniques are disclosed for providing a file system interface for an object store intended to support simultaneous access to objects stored in the object store by multiple clients. In accordance with one method, an abstraction of a root directory to a hierarchical namespace for the object store is exposed to clients. The object store is backed by a plurality of physical storage devices housed in or directly attached to the plurality of host computers and internally tracks its stored objects using a flat namespace that maps unique identifiers to the stored objects. The creation of top-level objects appearing as subdirectories of the root directory is enabled, wherein each top-level object represents a separate abstraction of a storage device having a separate namespace that can be organized in accordance with any designated file system.

Abstract translation: 公开了用于提供用于支持同时访问由多个客户端存储在对象存储中的对象的对象存储库的文件系统接口的技术。 根据一种方法，将根目录抽象到对象存储的分层命名空间将暴露给客户端。 对象存储由容纳在多个主机计算机中或直接附接到多个主机计算机的多个物理存储设备支持，并且使用将唯一标识符映射到所存储的对象的平面命名空间来内部跟踪其存储的对象。 启用显示为根目录子目录的顶级对象的创建，其中每个顶级对象表示具有可根据任何指定文件系统组织的单独命名空间的存储设备的单独抽象。
