摘要： An apparatus, system, and method are disclosed for maximizing power system holdup time during loss of input power. An energy storage module is included to deliver energy from an output stage of a first power supply to a bus. A power loss module is included to detect loss of power transmitting capability from an input stage of the first power supply to the output stage of the first power supply. A set-point reduction module is included to reduce an output voltage of the first power supply in response to the power loss module detecting loss of power transmitting capability. An isolation module is included to prevent energy flow from the energy storage module to the bus when the output voltage of the first power supply is lower than a voltage on the bus sustained by a second power supply.

摘要： A method is disclosed to set the signaling rate of a switch domain disposed in an information storage and retrieval system. The method establishes a switch domain target operating speed, and determines if that switch domain target operating speed comprises a first signaling rate. If the switch domain target operating speed comprises a first signaling rate, then the method asserts first Device Control Code bits to each of the plurality of data storage devices, and each of the plurality of data storage devices communicates with the switch using that first signaling rate. If the switch domain target operating speed does not comprise the first signaling rate, then the method asserts second Device Control Code bits to each of the plurality of data storage devices, and each of the plurality of data storage devices communicates with the switch using a second signaling rate.

摘要： A method to convert a plurality of sectors from a first sector format to a second sector format is disclosed. The method provides (N) contiguous first sectors comprising a first sector format to a sector format conversion device which includes a buffer and a data queue, where those (N) first sectors comprise a first number of bytes, and determines that (M) contiguous second sectors, comprising a second sector format, comprise at least the first number of bytes. The method overlays the (i)th first sector onto part or all of the (j)th second sector, and enqueues the newly-overlain (j)th second sector. The method then transmits the newly-overlain (j)th second sector to a data storage device, and writes that (j)th overlain second sector to an information storage medium.

摘要： A high density storage enclosure includes a plurality of storage devices, such as hard disk drives, positioned within a cooling airflow. Data to be stored to a storage device is received and a determination is made as to the expected usage of the data relative to other data stored on devices within the enclosure. The data is stored in a device having a position within the airflow relative to the source of the airflow in direct relationship to the relative expected usage of the data. Thus, data having a higher expected usage is stored in a device closer to the airflow source relative to other data having a lower expected usage and data having a lower expected usage is stored in a device farther from the airflow source relative to other data having a higher expected usage. Additionally, data may be dynamically relocated based upon actual usage.

摘要： A storage system includes a RAID adapter, disk array switches, sub-processors, and hard disk drives (HDDs). A disk-related operation is initiated in the RAID adapter. The RAID adapter dispatches a command to a disk array processor (or sub-processor) in an enclosure for the processor to perform the operation on one or more drives. The adapter may dispatch the command to a processor in a single enclosure through a disk array switch or to processors in multiple enclosures through switches in the upstream enclosures. The adapter is then free to perform other functions. The processor commences the specified operation on one or more selected drives, either sequentially one at a time or sequentially more than one (or all) at a time. Upon completion of the operation, the results are transmitted by the processor and received by the adapter. Thus, by offloading the task to the distributed sub-processors, the burden on the RAID adapter is significantly reduced, system bandwidth usage is reduced, and access to other drives within the enclosure (as well as within other enclosures) may be maintained. Tasks which may be offloaded in such a manner include, but are not limited to, drive firmware updating, drive scrubbing and secure data erasure.

摘要翻译： 存储系统包括RAID适配器，磁盘阵列交换机，子处理器和硬盘驱动器（HDD）。 磁盘相关操作在RAID适配器中启动。 RAID适配器将命令分配给机箱中的磁盘阵列处理器（或子处理器），以便处理器对一个或多个驱动器执行操作。 适配器可以通过磁盘阵列交换机将命令分派到单个机柜中的处理器，或通过上游机箱中的开关将命令分配到多个机箱中的处理器。 然后适配器可以自由执行其他功能。 处理器在一个或多个选定的驱动器上开始指定的操作，一次一个依次依次执行，或者一次连续执行多个（或全部）。 操作完成后，结果由处理器传送并由适配器接收。 因此，通过将任务卸载到分布式子处理器，RAID适配器的负担显着降低，减少了系统带宽使用，并且可以维护对外壳（以及其他机箱内）的其他驱动器的访问。 可以以这种方式卸载的任务包括但不限于驱动固件更新，驱动器擦除和安全数据擦除。

摘要： A method is disclosed to assign network addresses in a storage array disposed in a data storage and retrieval system comprising (P) data storage devices disposed in (N) data storage device assemblies. The method configures the (N) data storage device assemblies to comprise a spare data storage device assembly and a first storage array comprising (N−1) active data storage device assemblies, wherein each data storage device configured in the first storage array is assigned a network address, and wherein one of the spare data storage device disposed in the spare data storage device assembly is assigned a network address. In the event the method detects a failed data storage device disposed in the first storage array, then the method forms a second storage array comprising the first storage array, except the failed data storage device, in combination with the (i)th spare data storage device.

摘要： A method is disclosed to assign addresses to a plurality of data storage devices. The method provides a switch and (N) data storage devices, where each of those (N) data storage devices is interconnected with said switch. The method further establishes (M) device addresses, where (M) is less than (N), and assigns a different one of each of the (M) device addresses to a different one of the (N) data storage devices, such that the (N) data storage devices comprise (M) address-assigned data storage devices and (P) non-address-assigned data storage devices. The method then detects a failure of the (i)th address-assigned data storage device, and transfers the (i)th address from the failed address-assigned data storage device to the (j)th data storage device, where that O)th data storage device comprises one of the (P) previously non-addressed data storage devices.
