摘要： A disk caching method for an intermediary controller is disclosed. Requests for data blocks are made and then disk caching is performed according to a most expedient cache method. The disk caching method may be performed by asynchronously requesting a data record from both a intermediary controller disk storage and from a intermediary controller cache and using a first received copy of the data record, the first received copy being a copy received first from the intermediary controller disk storage. Alternatively, the disk caching may be performed by searching an intermediary controller cache to determine whether requested data is located in the cache of the intermediary controller, searching a storage device of the intermediary controller to determine whether requested data is located in the storage device of the intermediary controller and retrieving the requested data from a disk controller coupled to the intermediary controller when the requested data is not in the cache or storage device of the intermediary controller. The intermediary controller maintains a cache hit ratio for cache in a disk controller cache and chooses a cache method based upon a comparison of the hit ratio to the threshold. The intermediary controller selects an item to replace in the intermediary controller cache, moves data into the intermediary controller cache, determines whether the hit ratio of the disk controller is greater than the threshold and moves the item into the intermediary controller storage device when the hit ratio of the disk controller cache is greater than the threshold. The intermediary controller discards the item form the cache of the intermediary controller when the hit ratio of the disk controller is not greater than the threshold.

摘要： A file system driver stored in a computational device receives a request to provide access to a snapshot of a rewritable file system at a selected point in time, wherein a plurality of tokens corresponding to a plurality of data units are stored in the rewritable file system, and wherein an ordering relationship is maintained among the plurality of tokens. The file system driver determines a token corresponding to the selected point in time based on the ordering relationship. A virtual subdirectory name is generated corresponding to the determined token. A virtual subdirectory is created with the generated virtual subdirectory name, wherein the virtual subdirectory is a subdirectory of a root directory. The snapshot is accessed via the subdirectory.

摘要： A multi-port adapter and method for scheduling jobs at the adapter input/output ports. A plurality of queues are provided, each associated with one of the input/output ports. A processor arranges the jobs in each of the queues in a normal queued order for selection by the associated port. Upon selecting a next job for one of the ports, the processor determines the number of queued jobs of each of the queues for each of the other ports; and determines whether the number of queued jobs of each queue for the other ports is less than a threshold. If the number of jobs is less than the threshold, the processor selects the next job for the one port from the jobs in the queue for the one port identified as one that may be conducted in out of queue order, e.g., having attached heuristic information; else, selects the next job for the one port from the jobs in the queue for the one port on the normal queued basis. The identified job may be part of an operation involving two of the ports, and gives the job priority so that another port is less likely to have to be idle while waiting for the one port.

摘要： A data storage system stores data with a corresponding encapsulated metadata token in cache and/or base storage to protect against recalling stale data from base storage in the event of a cache failure and subsequent cache miss. A controller is coupled to a cache, base storage, and token database. After receiving a data object and associated write request, the controller assigns a version code to the data object. If the data object already exists, the controller advances the data object's version code. A token, including the version code along with other items of metadata, is encapsulated for storage. Then, the controller stores the data object and encapsulated token in cache and/or base storage and updates the token database to cross-reference the data object with its version code. When the controller experiences a cache miss, there is danger in blindly retrieving the data object from base storage since the cache miss may have occurred due to cache failure before the data was de-staged, leaving a down-level version of the data object on base storage. This problem is avoided by comparing the data object's version code contained in base storage to the version code listed for the data object in the token database. Only if the compared version codes match, the data object is read from base storage and provided as output.
摘要翻译：数据存储系统将具有对应的封装元数据令牌的数据存储在高速缓存和/或基本存储器中，以防止在高速缓存失败和随后的高速缓存未命中的情况下从基本存储器调用过时的数据。控制器耦合到高速缓存，基本存储和令牌数据库。在接收到数据对象和相关的写入请求后，控制器将向数据对象分配版本代码。如果数据对象已经存在，则控制器提前执行数据对象的版本代码。包含版本代码以及其他元数据项的令牌被封装以进行存储。然后，控制器将数据对象和封装的令牌存储在高速缓存和/或基本存储中，并更新令牌数据库以与其版本代码交叉引用数据对象。当控制器遇到高速缓存未命中时，存在从基本存储器盲目地检索数据对象的危险，因为在数据被解除之前由于高速缓存失败而可能已经发生高速缓存未命中，从而将数据对象的下级版本基地存储。通过将基本存储中包含的数据对象的版本代码与令牌数据库中的数据对象列出的版本代码进行比较可以避免此问题。只有比较版本代码匹配，数据对象才能从基础存储器读取并作为输出提供。

摘要： A particularly efficient storage system makes redundant copies of data on tape by waiting until a rewind/unload command is received and then copying stored data objects en masse, thereby benefitting from any data compression used to store the objects along with the lower overhead for the copy operation. This copy operation is more efficient than the data objects' original storage, because there is less overhead in copying the data objects en masse; also, there is less data to copy if the data objects were stored with any data compression. Efficiency may be further increased by dividing the task of originally writing the data objects between paired tape drives, and then exchanging data objects between the tape drives upon issuance of the rewind/unload command.
摘要翻译：一个特别高效的存储系统通过等待直到接收到倒带/卸载命令，然后再次复制存储的数据对象，从而从用于存储对象的任何数据压缩以及副本的较低开销操作。这种复制操作比数据对象的原始存储效率更高，因为大量复制数据对象的开销较少; 如果数据对象与任何数据压缩一起存储，则还有较少的数据要复制。通过将最初写入数据对象的任务划分成成对的磁带驱动器，然后在发出回卷/卸载命令之后在磁带驱动器之间交换数据对象，可以进一步提高效率。
