摘要： A method in a storage system reads blocks having both physical addresses and logical addresses in the storage system from a first set of locations in non-volatile storage to a cache memory and determines the level of data fragmentation in the non-volatile storage. If the level of data fragmentation exceeds a threshold level, the cache memory is marked and the blocks are written to physically sequential locations with new physical addresses in the non-volatile storage at a data consistency point without changing the logical addresses of the blocks.
摘要翻译：存储系统中的方法将具有存储系统中的物理地址和逻辑地址的块从非易失性存储器中的第一组位置读取到高速缓冲存储器，并确定非易失性存储器中的数据碎片级别。如果数据碎片级别超过阈值级别，则将高速缓存存储器标记，并且将数据块写入物理顺序位置，并在数据一致性点的非易失性存储器中新的物理地址，而不改变块的逻辑地址。

摘要： A storage controller is operable concurrently as an independent storage server and as at least a portion of a node of a storage server cluster. A network storage system comprises multiple storage controllers and multiple independent storage servers, each storage server implemented in a separate storage controller, each of the storage server configured to present to users a separate system image of stored data. The storage servers are independently operable and manageable. The system further includes a storage server cluster that includes cooperating storage server nodes, distributed among the storage controllers. The storage server cluster presents to users a single system image of data stored in the server cluster independently of the node or nodes in which said data resides. The storage server cluster is operable independently of the independent storage servers and is operable concurrently with operation of at least one of the independent storage servers.
摘要翻译：存储控制器可以作为独立存储服务器并且作为存储服务器集群的节点的至少一部分同时操作。网络存储系统包括多个存储控制器和多个独立存储服务器，每个存储服务器在单独的存储控制器中实现，每个存储服务器被配置为向用户呈现存储数据的单独的系统映像。存储服务器是独立可操作和可管理的。该系统还包括存储服务器集群，其包括分配在存储控制器之间的协作存储服务器节点。存储服务器集群向用户呈现存储在服务器集群中的数据的单个系统映像，而不管所述数据所在的节点或节点。存储服务器集群可独立于独立存储服务器操作，并且与至少一个独立存储服务器的操作同时操作。

摘要： A storage system, such as a file server, creates persistent consistency point images (PCPI) or “snapshots” that are point-in-time representations of the storage system. The storage system uses persistent consistency point images to backup or mirror data. Using data already found in the data block maps associated with these PCPI, the amount of space used by a set of these consistency points can be determined.

摘要： A file system receives a request to set a capacity guarantee for a virtual volume associated with a logical aggregation of physical storage. In response, the file system sets the capacity guarantee to indicate that the logical aggregation of physical storage is to provide a specified amount of space to the virtual volume. The amount of space provided to the virtual volume may be based, at least in part, on a guarantee type. The guarantee type may include, for example, volume, file, none, or partial.

摘要： The reserves of a flexible volume and the aggregate which contains the flexible volume are “stacked”. When the flexible volume is created, a portion of the flexible volume having a capacity equal to or less than an unreserved portion of the flexible volume is guaranteed by the aggregate. When the flexible volume creates or modifies metadata, the flexible volume issues a request to the aggregate. The aggregate then issues a portion of the reserve of the aggregate to the flexible volume for storing the metadata.
