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。
