摘要： Performance information for storage units located at a virtual data center is determined by executing storage administrator logic whose execution is controlled by a management entity different than the virtual data center provider. Performance expectations are automatically determined based on the determined performance information. In response to determining that a particular storage unit is incompatible with performance expectations applicable to the particular storage unit, embodiments cause a reduction in utilization of the particular storage unit. Based on determined performance information, another embodiment determines that a performance pattern indicating a physical co-location of a first storage unit and a second storage unit has occurred. In response to determining that the performance pattern indicating a physical co-location of a first storage unit and a second storage unit has occurred, the embodiment disables use of a selected storage unit of the first storage unit or the second storage unit for at least a particular purpose.

摘要： The present invention discloses a data access method and apparatus, and belongs to the field of information technologies. The method includes: acquiring a data read request that is for a first disk group and carries a read address; determining a first-stripe location range of the first disk group according to the read address; sequentially reading data from first stripes within the first-stripe location range; setting a data reading result for a first stripe whose data is not successfully read to preset padding data, and continuing to read data from a next first stripe until data is read from all the first stripes; and returning a data reading result for each first stripe. In the present invention, a data reading result for a first stripe whose data is not successfully read is set to preset padding data, data reading proceeds to a next first stripe until data is read from all first stripes, and a data reading result for each first stripe is returned, which reduces data loss and shortens access interruption time when data is not successfully read.

摘要： A system and method for effectively scheduling read and write operations among a plurality of solid-state storage devices. A computer system comprises client computers and data storage arrays coupled to one another via a network. A data storage array utilizes solid-state drives and Flash memory cells for data storage. A storage controller within a data storage array comprises an I/O scheduler. The characteristics of corresponding storage devices are used to schedule I/O requests to the storage devices in order to maintain relatively consistent response times at predicted times. Should a device exhibit an unscheduled behavior which may be indicative of the device being in an unknown state, the scheduler may schedule one or more reactive operations on the device configured to cause the device to enter a known state.

摘要： This application discloses a storage system, a storage device, and a hard disk drive scheduling method. The storage system includes M disk groups, a power supply system, and a controller, and M is a natural number not less than 3. Each of the M disk groups includes at least one hard disk drive configured to store data, and each hard disk drive includes an inactive state, a spin up state, and an active state. Power supplied by the power supply system to the storage system allows one of the M disk groups to be in the active state and another disk group to be in the spin up state. The controller is connected to the M disk groups and configured to: control a hard disk drive in a first disk group of the M disk groups to be in the active state to process a first group of service requests, and when the hard disk drive in the first disk group is in the active state, control a hard disk drive in a second disk group of the M disk groups to switch from the inactive state to the spin up state. The second disk group is configured to process a second group of service requests.

摘要： A method of controlling an ultra-deep power down (UDPD) mode in a memory device, can include: receiving a write command from a host via an interface; beginning a write operation on the memory device to execute the write command; reading an auto-UDPD (AUDPD) configuration bit from a status register; completing the write operation on the memory device; automatically entering the UDPD mode upon completion of the write operation in response to the AUDPD configuration bit being set; and entering a standby mode upon completion of the write operation in response to the AUDPD configuration bit being cleared.

摘要： Embodiments of the present invention disclose a storage array operation method and apparatus. The method may include: receiving an operation instruction that is delivered by a target service object and that is directed at a cache of a storage array, where service objects supported by the storage array are divided into at least one performance group, and allowable operation traffic is calculated for each performance group in advance; selecting, from the at least one performance group, a target performance group to which the target service object belongs, and determining whether there is still remaining traffic in allowable operation traffic of the target performance group; and responding to the operation instruction if there is still remaining traffic in the allowable operation traffic of the target performance group; or rejecting the operation instruction if there is no remaining traffic in the allowable operation traffic of the target performance group. The embodiments of the present invention can resolve a performance degradation problem of converged storage.

摘要： A method for monitoring movements of a user using a flexible circuit member. The flexible circuit member is fault tolerant. The method may include using extra and/or redundant traces as well as storing data on RAM if the flash memory fails or if some or all trace connections between the processor and flash memory fail. Data may or may not be stored on the RAM containing less fidelity. Lower fidelity data may be used to alleviate issues arising if the RAM has less storage capacity than the flash memory.

摘要： Each node and volume in a fixed-content storage cluster makes an independent decision whether to reduce power consumption based on lack of requests from client applications and nodes over a configurable time period. Node configuration parameters sleepAfter and wakeAfter respectively determine how long to wait until idling a node or volume, and how long to wait while idle before again performing integrity checks. A bid value is calculated by each node and reflects how much it will cost for that node to write a file, read a file, or keep a copy of the file. A node with the lowest bid wins, and nodes that are idle have a premium added to each bid to help ensure that idle nodes are kept idle. Normally, nodes with more capacity will submit a lower bid to write a file. In an archive mode, writes bids are reversed meaning that nodes with less capacity submit lower bids, meaning that fuller nodes fill up faster and are then idled, while empty or near empty nodes may remain idle for some time before winning a write bid.
摘要翻译：固定内容存储群集中的每个节点和卷根据缺少客户端应用程序和节点在可配置时间段内的请求来做出是否降低功耗的独立决策。节点配置参数sleepAfter和wakeAfter分别确定在空闲节点或卷之前等待多长时间，以及在再次执行完整性检查之前等待空闲多久。出价值由每个节点计算并反映该节点写入文件，读取文件或保留文件副本的成本。出价最低的节点获胜，闲置的节点会为每次出价添加溢价，以帮助确保空闲节点闲置。通常情况下，具有更多容量的节点会提交较低的出价来编写文件。在归档模式下，写入出价是相反的，这意味着容量较小的节点提交的出价较低，这意味着更全面的节点填满得更快，然后空闲，而空的或接近空的节点在赢得写出价之前可能保持空闲一段时间。
