    Abstract: A method of performing a global deduplication may include: collecting a data chunk to be written to a backing storage of a storage system at a staging area in the storage system; generating a data fingerprint of the data chunk; sending the data fingerprint in batch along with other data fingerprints corresponding to data chunks collected at different times to a metadata server system in the storage system; receiving an indication, at the staging area, of whether the data fingerprint is unique in the storage system from the metadata server system; and discarding the data chunk when committing a data object containing the data chunk to the backing storage, when the indication indicates that the data chunk is not unique.

    Abstract translation: 执行全局重复数据删除的方法可以包括:收集要写入存储系统中的暂存区域的存储系统的后备存储器的数据块; 生成数据块的数据指纹; 批量发送数据指纹以及对应于不同时间收集的数据块的其他数据指纹到存储系统中的元数据服务器系统; 在分段区域接收来自元数据服务器系统的数据指纹在存储系统中是否唯一的指示; 并且当指示表示数据块不是唯一时,将包含数据块的数据对象提交给后备存储器时丢弃数据块。

    Abstract: A distributed object store in a network storage system uses location-independent global object identifiers (IDs) for stored data objects. The global object ID enables a data object to be seamlessly moved from one location to another without affecting clients of the storage system, i.e., “transparent migration”. The global object ID can be part of a multilevel object handle, which also can include a location ID indicating the specific location at which the data object is stored, and a policy ID identifying a set of data management policies associated with the data object. The policy ID may be associated with the data object by a client of the storage system, for example when the client creates the object, thus allowing “inline” policy management. An object location subsystem (OLS) can be used to locate an object when a client request does not contain a valid location ID for the object.

    Abstract translation: 网络存储系统中的分布式对象存储使用与存储的数据对象的位置无关的全局对象标识符(ID)。 全局对象ID使数据对象无缝地从一个位置移动到另一个位置,而不会影响存储系统的客户端,即“透明迁移”。 全局对象ID可以是多级对象句柄的一部分,其还可以包括指示存储数据对象的特定位置的位置ID,以及标识与数据对象相关联的一组数据管理策略的策略ID。 策略ID可以由存储系统的客户端与数据对象相关联,例如当客户端创建对象时,从而允许“内联”策略管理。 当客户机请求不包含对象的有效位置ID时,可以使用对象位置子系统(OLS)来定位对象。
