Abstract: A storage system comprises a controller; a memory; and one or more objects each including content data and metadata. The metadata is used to construct user-defined content properties, each content property providing an ability to extract a specific metadata field from the objects by referring to a user-defined content property name of the content property. The content properties are organized into user-defined content classes, each content class grouping a set of content properties into a named category under a user-defined content class name. The controller is operable to index the content properties of the content classes to create an index. The content properties being indexed are identified by the content property names. In some embodiments, the controller is operable to de-dupe the index, for content properties having same values expressed differently in different metadata formats, by directing the differently expressed values to same index field under same content property name.

Abstract: In some examples, a plurality of content properties may be used for managing indexing of object data, such as a plurality of files. Each content property may include an expression for extracting data values from specific data fields in the object data. Further, each content property may include a name that may be used for indexing the objects using the extracted data values. For instance, multiple content properties may have the same name, but may each have different expressions for extracting different data values from different data fields. Accordingly, the content properties may be used to extract desired data values from the objects for indexing. When a search query is received including a content property name and a specified value, one or more of the objects that are indexed with the specified value may be searched.

Abstract: A storage system stores objects and copies of objects on the storage system and other storage systems external to the storage system. The storage system stores the copies in storage pools of volumes, which are organized into one or more tiers. The configuration settings of each tier and each pool within the tier may be configured according to a user's preferences. In one example, the number of copies of data content and the number copies of metadata associated with the data content an individual pool stores may be specified. When objects are migrated between tiers, the objects are stored among the storage pools of the tiers. If the number of data content copies or metadata copies is increased, the data or metadata is copied from a determined copy source and if the number of copies decreases, the data is removed from the volumes in the pools.

Abstract translation: 存储系统将对象和对象副本存储在存储系统和存储系统外部的其他存储系统中。 存储系统将副本存储在卷的存储池中，它们被组织成一个或多个层。 可以根据用户的偏好来配置层内每个层和每个池的配置设置。 在一个示例中，可以指定数据内容的副本数量和与个人池存储的数据内容相关联的元数据的副本。 当层之间迁移对象时，对象将存储在各层的存储池中。 如果增加数据内容副本或元数据副本的数量，则从确定的复制源复制数据或元数据，如果副本数量减少，则数据将从池中的卷中删除。
