摘要： A method to initialize information disposed in an information storage and retrieval system comprising a data cache and one or more information storage media comprising a plurality of addresses. The method receives an initialization command, where that initialization command comprises a range of addresses and, optionally, an initialization pattern, where the plurality of addresses includes the range of addresses. The method forms and saves state information, where that state information includes the initialization pattern, and generates and saves a plurality of indicators, where that plurality of indicators includes an indicator for each track comprising the range of addresses. The method sets each of those indicators to a first value thereby indicating special handling, and provides an ending status signal, such that the receiving step, forming step, generating step, setting step, and providing step are performed substantially synchronously.

摘要： A communication-path management system includes a path-detection component for identifying all communications paths between a host computer, through a controller, to a data storage device. Once identified, the communication paths are incorporated into a logical-path mask. The path-detection component recognizes each path as either preferred or non-preferred based on latency, bandwidth, availability, or other user-defined criteria and divides the logical-path mask into a preferred path subset and a non-preferred path subset. If a valid path exists in the preferred path subset, all communications from the host computer to the data storage device transit paths belonging to this subset. Otherwise, active control is given to the non-preferred path subset. A channel subsystem manages actual communication based on resource allocation and contention using the currently active subset.
摘要翻译：通信路径管理系统包括用于识别通过控制器的主机与数据存储设备之间的所有通信路径的路径检测组件。一旦识别，通信路径被合并到逻辑路径掩码中。路径检测组件基于延迟，带宽，可用性或其他用户定义的标准将每个路径识别为优选的或不优选的，并将逻辑路径掩码划分成优选的路径子集和非优选的路径子集。如果优选路径子集中存在有效的路径，则从主计算机到数据存储设备的所有通信都将传输属于此子集的路径。否则，给予非优选路径子集的主动控制。信道子系统使用当前活动的子集来管理基于资源分配和争用的实际通信。

摘要： A method, apparatus and program storage device for protecting data write operations against write failures in a data storage device is provided. The data storage device includes a storage medium, a write cache including a copy of data written to the storage medium, and a controller configured for testing data write operations to the storage medium. The controller tests data write operations to the storage medium before the write cache is flushed to confirm that it is safe to flush the write cache. If the test fails, the data in the write cache can be recovered.

摘要： One aspect of the invention is a method for configuring an array of storage devices to reduce the probability of data loss due to clustered storage device failures in the array. An example of this method includes identifying all storage devices in a primary set of storage devices and a first mirror set of storage devices in the array of storage devices. This example also includes obtaining data regarding each identified storage device. This example further includes determining if any of the storage devices in the primary set of storage devices has a vital characteristic that is the same as a vital characteristic of any of the storage devices in the first mirror set of storage devices, and if so, indicating an array configuration error, and if not, continuing the configuration.

摘要： In a data storage controller, accessed tracks are temporarily stored in a cache, with write data being stored in a first cache (such as a volatile cache) and a second cache and read data being stored in a second cache (such as a non-volatile cache). Corresponding least recently used (LRU) lists are maintained to hold entries identifying the tracks stored in the caches. When the list holding entries for the first cache (the A list) is full, the list is scanned to identify unmodified (read) data which can be discarded from the cache to make room for new data. Prior to or during the scan, modified (write) data entries are moved to the most recently used (MRU) end of the list, allowing the scans to proceed in an efficient manner and reducing the number of times the scan has to skip over modified entries Optionally, a status bit may be associated with each modified data entry. When the modified entry is moved to the MRU end of the A list without being requested to be read, its status bit is changed from an initial state (such as 0) to a second state (such as 1), indicating that it is a candidate to be discarded. If the status bit is already set to the second state (such as 1), then it is left unchanged. If a modified track is moved to the MRU end of the A list as a result of being requested to be read, the status bit of the corresponding A list entry is changed back to the first state, preventing the track from being discarded. Thus, write tracks are allowed to remain in the first cache only as long as necessary.
摘要翻译：在数据存储控制器中，将访问的轨道临时存储在高速缓存中，其中写入数据被存储在第一高速缓存（例如易失性高速缓存）和第二高速缓存中，并且将读取的数据存储在第二高速缓存（例如，易失性缓存）。保持相应的最近使用的（LRU）列表来保存标识存储在高速缓存中的轨道的条目。当保存第一个缓存（A列表）的条目的列表已满时，将扫描列表以识别可以从缓存中丢弃的未修改（读取）数据，为新数据腾出空间。在扫描之前或期间，修改（写入）数据条目移动到列表的最近使用（MRU）端，允许扫描以有效的方式继续进行，并减少扫描必须跳过修改的次数条目可选地，状态位可以与每个修改的数据条目相关联。当修改的条目移动到A列表的MRU结尾而不被请求读取时，其状态位从初始状态（例如0）改变到第二状态（例如1），表示它是候选人被丢弃。如果状态位已经设置为第二个状态（如1），那么它将保持不变。如果作为被请求读取的结果将经修改的轨道移动到A列表的MRU端，则相应的A列表条目的状态位被改回到第一状态，防止轨道被丢弃。因此，仅在需要时才允许写轨迹保留在第一缓存中。
