Abstract: To effectively implement ILM policies and account for unreliability in a geographically distributed large-scale storage system, "scanners" and "ILM rules appliers" can be deployed on nodes throughout the storage system for large scale ILM implementation. Each scanner is programmed to deterministically self-assign a region of object namespace and scan that region of object namespace. To "scan" a region, a scanner accesses metadata of each object that has an identifier within the scanner's region and inserts the object metadata into one of a set of queues for ILM evaluation. An ILM rules applier dequeues object metadata for evaluation against ILM rules and determines whether an ILM task is to be performed for ILM rule compliance.

Abstract: To leverage the attributes of object storage for applications/systems configured to interface with a network type file system, an object storage backed file system can accept the defined file system commands from the applications/systems and transform the file system commands into requests that target object storage. The file system is "backed" by object storage because attributes and content of file system entities are stored in objects. For instance, content data and metadata of a file are stored in objects in object storage. This object storage backed file system can be considered a bridge between a client perceived hierarchical file system namespace and a flat namespace of an object storage.

Abstract translation: 为了利用配置为与网络类型文件系统接口的应用/系统的对象存储的属性，对象存储支持的文件系统可以接受来自应用/系统的定义的文件系统命令，并将文件系统命令转换成目标对象的请求 存储。 由于文件系统实体的属性和内容存储在对象中，文件系统由对象存储“支持”。 例如，文件的内容数据和元数据存储在对象存储中的对象中。 该对象存储支持文件系统可以被认为是客户机感知的分层文件系统命名空间与对象存储的平面命名空间之间的桥梁。
