摘要： Described embodiments provide a server for transferring data packets of streaming data sessions between devices. A redundant array of inexpensive disks (RAID) array having one or more stripe sector units (SSU) stores media files corresponding to the one or more data sessions. The RAID control module receives a request to perform the write operation to the RAID array beginning at a starting data storage address (DSA) and pads the data of the write operation if the amount of data is less than a full SSU of data, such that the padded data of the write operation is a full SSU of data. The RAID control module stores the full SSU of data beginning at a starting data storage address (DSA) that is aligned with a second SSU boundary, without performing a read-modify-write operation.

摘要： In one embodiment, a method for reading data from a storage-device array including three or more storage devices. The array has a plurality of sector levels, each sector level containing one sector on each storage device in the array at corresponding addresses across the storage devices. Each sector level includes (i) parity data stored on a first storage device and (ii) information stored on the two or more remaining storage devices. The parity data for a current sector level is generated from the information stored at the current sector level on the remaining storage devices. The method includes: (a) generating an instruction for reading (i) the parity data from the first storage device at the current sector level and (ii) the information from the remaining storage devices at the current sector level; (b) receiving an indicator indicating whether one of the remaining storage devices is a degraded storage device; (c) if the indicator does not indicate a degraded storage device, then providing as output the information read from the remaining storage devices at the current sector level; and (d) if the indicator does indicate a degraded storage device, then: (d1) reconstructing information previously stored on the degraded storage device at the current sector level based on (i) the parity data read from the first storage device at the current sector level, and (ii) the information read from each remaining non-degraded storage device at the current sector level; and (d2) providing as output (i) the information read from the one or more non-degraded storage devices at the current sector level and (ii) the reconstructed information.

摘要： A method includes storing first and second sets of parameters in a register. Each set of parameters defines a storage transaction to store data to a computer readable medium or a retrieval transaction to retrieve data from the computer readable medium. The first storage or retrieval transaction is performed according to the first set of parameters. The second set of parameters is retrieved from the register automatically when the first storage or retrieval transaction is completed, without waiting for a further command from a control processor. The second storage or retrieval transaction is performed according to the retrieved second set of parameters. A system for performing the method and a computer readable medium containing pseudocode for generating an application specific integrated circuit that performs the method are provided.

摘要： A method includes assigning each of a plurality of disk write and disk read requests to respective ones of a plurality of queues. Each queue has an occupancy level and a weight. A score is assigned to each of the plurality of queues, based on the occupancy and weight of the respective queue. An operation type is selected to be granted a next disk access. The selection is from the group consisting of disk write, disk read, and processor request. One of the queues is selected based on the score assigned to each queue, if the selected operation type is disk write request or disk read request. The next disk access is granted to the selected operation type and, if the selected operation type is disk write or disk read, to the selected queue.

摘要： Methods and apparatus are provided for reducing disk seek time to improve the overall throughput by improving the scheduling of read requests. One or more requests to read data from one or more disks are scheduled by suspending one or more requests to read data from the disk for a predefined period of time. The read suspension can be initiated, for example, in response to a request to read data from the disk, such as a speculative read operation. The predefined period of time may be approximately equal, for example, to an expected duration of the read request operation, an expected seek time, a predefined recovery time or a time since a last request less a recovery time. The read suspension can be conditioned upon one or more predefined criteria, such as a disk bandwidth threshold being satisfied, a time since a last request threshold being satisfied and a condition that only a request for a different stream than a currently requested stream is suspended.
摘要翻译：提供了通过改进读请求的调度来减少磁盘查找时间以提高整体吞吐量的方法和装置。通过在预定义的时间段内暂停从盘读取数据的一个或多个请求来调度从一个或多个磁盘读取数据的一个或多个请求。可以例如响应于从盘读取数据的请求（例如推测性读取操作）来启动读取的暂停。预定义的时间段可以近似相等，例如，读取请求操作的预期持续时间，预期寻道时间，预定义的恢复时间或自上次请求以来的时间减去恢复时间。读取的暂停可以根据一个或多个预定义的标准来调节，例如满足磁盘带宽阈值，满足最后一个请求阈值的时间，以及仅暂停对当前请求流的不同流的请求的条件。
