    摘要： Mechanisms identify one or more first storage devices in a first tier of the tiered storage system that may be placed in a minimal power consumption state and identify one or more data segments stored on the one or more first storage devices that are most likely to be accessed during a period of time in which the one or more first storage devices are in the minimal power consumption state. The mechanisms migrate the one or more data segments to one or more second storage devices in one of the first tier or a second tier of the storage system and place the one or more first storage devices in the minimal power consumption state. Access requests to the one or more data segments are serviced by the one or more second storage devices while the one or more first storage devices are in the minimal power consumption state.

    摘要： A self-contained backup power source such as a battery is provided for components within an electrically powered device such as a storage controller, photocopier or the like, to maintain diagnostic status data and to power a service indicator aid, or diagnostic indicator, such as an LED. A switch selects the backup power source when a primary power source of the electrically powered device is no longer available to the component, such as when the component is removed from the electrically powered device, the primary power source is disconnected as a safety precaution when servicing or replacing the component, or a higher-level assembly, in which the component is provided, is removed from the electrically powered device. The diagnostic indicator may be powered separately from the data storage device.

    摘要： A back-up power source and a back-up storage device are utilized to power a processor and a volatile memory device during a primary power failure. An emergency data-storage algorithm is invoked to create a table of modified data analogous to data residing in a non-volatile memory device associated with a different processor. This table of modified data is written to the back-up storage device.

    摘要： An apparatus and method to check integrity when handling data. The method provides a storage array which includes a plurality of sectors. The method defines (N) data state identifiers and (N) parity state identifiers. The method receives a command to handle data, where that command designates a target sector. The method determines the data state identifier assigned to the target sector, determines the parity state identifier assigned to the target sector, and compares the data state identifier and the parity state identifier. If the method determines that the data state identifier and the parity state identifier are the same, the method performs the command to handle data. Alternatively, if the method determines that the data state identifier and the parity state identifier differ, the method generates an error message.

    摘要： A mechanism is provided for optimizing and enhancing performance for parity based storage, particularly redundant array of independent disk (RAID) storage. The mechanism optimizes a repetitive pattern write command for performance for storage configurations that require parity calculations. The mechanism eliminates the need for laborious parity calculations that are resource intensive and add to IO latency. For repetitive write commands that span across the full stripe of a RAID5 or similar volume, the mechanism calculates parity by looking at the pattern and the number of columns in the volume. The mechanism may avoid the XOR operation altogether for repetitive pattern write commands. The mechanism may enhance secure delete operations that use repetitive pattern write commands by eliminating data reliability operations like parity generation and writing altogether.

    摘要翻译： 提供了一种机制，用于优化和增强基于奇偶校验的存储，特别是独立磁盘（RAID）存储的冗余阵列的性能。 该机制优化了重复性模式写入命令，以获得需要奇偶校验计算的存储配置的性能。 该机制消除了对资源密集型并增加IO延迟的费力奇偶校验计算的需要。 对于跨越RAID5或类似卷的整个条带的重复写入命令，该机制通过查看卷中的模式和列数来计算奇偶校验。 该机制可以避免重复模式写入命令的XOR操作。 该机制可以通过消除数据可靠性操作（如奇偶校验生成和写入）来增强使用重复模式写入命令的安全删除操作。
