摘要： A RAID system is provided for detecting and correcting dropped writes in a storage system. Data and a checksum are written to a storage device, such as a RAID array. The state of the data is classified as being in a “new data, unconfirmed” state. The state of written data is periodically checked, such as with a timer. If the data is in the “new data, unconfirmed” state, it is checked for a dropped write. If a dropped write has occurred, the state of the data is changed to a “single dropped write confirmed” state and the dropped write error is preferably corrected. If no dropped write is detected, the state is changed to a “confirmed good” state. If the data was updated through a read-modified-write prior to being checked for a dropped write event, its state is changed to an “unquantifiable” state.

摘要： A high density storage enclosure houses first and second pluralities of hard disk drives (HDDs). The enclosure may be partitioned into a plurality of virtual enclosures, the first plurality of HDDs being associated with a first virtual enclosure and the second plurality of HDDs being associated with a second virtual enclosure. Configuration of the storage enclosure is performed by an SES processor in the storage enclosure accessing configuration parameters received from an external configuration unit coupled to the storage enclosure. The virtual enclosures may be configured as two (or more) independent virtual enclosures on two (or more) independent fabrics or may be configured in a trunked manner. Power supplies and cooling blowers in the storage enclosure may also be partitioned and assigned to be managed by SES processors in the virtual enclosures.

摘要： The advanced management module services in a data processing system are configured to determine the system load and provide an input to the early power off warning detection logic that evaluates the power system state to detect a condition when power resources are insufficient to maintain the write caching storage system power within defined acceptable limits. The early power off warning detection logic generates a notification based on the system load and the available power supply resources to maintain maximum availability and reliability characteristics.

摘要： The write operations to the storage devices are managed so that the write operations that would force a storage device to reposition its read/write head outside its read optimization boundary are queued until a threshold is reached. Upon reaching the write queue threshold, the write operations are sent to the storage devices in a burst mode that limits the impact of storage device seek operations that force the device read/write head out of position relative to the data that is assigned as it's primary read region, keeping the read/write head in it's primary locality to optimize the performance of read operations.
摘要翻译：对存储设备的写入操作被管理，使得迫使存储设备将其读/写头重新定位在其读取优化边界之外的写入操作被排队，直到达到阈值。在达到写入队列阈值时，写入操作以突发模式发送到存储设备，该模式限制存储设备查找操作的影响，从而强制设备读取/写入头相对于被分配为主要的数据的位置读取区域，将读/写头保持在其主要位置以优化读取操作的性能。

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 storage array disposed in a data storage system is reconfigured. A data storage system is supplied comprising a plurality of data storage devices, wherein each of the plurality of data storage devices is assigned to one of a plurality of data storage arrays, or is assigned as a spare device. An unassigned data storage device is detected. If any of the plurality of data storage arrays comprises an intermixed data storage array, the storage array is reconfigured to restore the intermixed data storage array to a homogeneous technology class comprising the unassigned device. If any of the plurality of data storage arrays comprises a degraded data storage array, the storage array is reconfigured to restore the degraded storage array to optimal reliability, optimal performance, and optimal efficiency.

摘要： In a RAID storage system, a parity value is generated. The storage system includes a RAID adapter, a plurality of disk array processors managing corresponding sets of RAID storage drives, and a connecting fabric. The RAID adapter initiates a parity generation operation, parallel instructions are dispatched for the array processors to each generate a partial parity value from data blocks on drives on respective managed RAID storage drives, the partial parity value is received in the RAID adapter from each array processor, and the partial parity values are combined in the RAID adapter to generate a complete parity value. The parity value may be an actual parity block to be stored on a hard disk drive or may be a reconstructed data block in the event of a failed drive.

摘要： A data storage domain is provided to determine a set of signal conditioning parameters for data being transmitted over smart cables in a data storage domain between an SAS switch and SAS expanders and among SAS expanders. A first expander interrogates any attached smart cables for cable persistent data and captures in a table the cable persistent data. One or more interfaces of the first expander are operated at a first data rate. The switch collects the captured cable persistent data and, in response, determines a set of signal conditioning parameters for data being transmitted on each attached smart cable. The set of signal conditioning parameters includes a first maximum data rate for each attached smart cable. The signal conditioning parameters are then set for each attached smart cable in accordance with the set of determined signal conditioning parameters, whereby the data storage domain is tuned for optimum signal transmission.

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 computer-implemented method replaces a redundant array of independent disks (RAID) array member storage device configured in high density packaging. The high density packaging includes a plurality of field-replaceable units (FRUs). Each FRU has an associated plurality of storage devices. A first spare storage device of a first FRU is captured. The first FRU is dedicated as a plurality of spare storage devices by a RAID controller. A small computer system interface (SCSI) enclosure services (SES) processor (SESP) is initialized to read data from the RAID array member storage device and transfer the data to the first spare storage device. The first spare storage device and the RAID array member storage device are co-resident within a serial attached small computer system interface (SAS) expander local port domain.
