摘要： Method, system and computer program product are provided to improve the reliability of data transfers from RAID systems. Although some read errors may be detected by the RAID controller, other errors may not be; undetected errors may affect the integrity of the data. In accordance with the present invention, the host or client issues a first command to the RAID controller to read specified data. After the RAID controller obtains the data from the RAID drives and transmits it to the host, the host verifies the data to detect any errors. If an error is detected by the host, the host issues a second command to the RAID controller to reconstruct the specified data, rather than merely re-read the data. The reconstructed data is then transmitted to the host. Consequently, previously undetected and uncorrected errors may be detected and corrected by the host.

摘要： A method for replacing a failed storage device in a storage device array includes detecting that the storage device has failed, and reconstructing data that was stored on the failed storage device. The method also includes commencing writing the reconstructed data on each of a plurality of spare storage devices, without verifying that the reconstructed data is successfully written, and finishing writing the reconstructed data on at least one of the spare storage devices. The method further includes beginning validating that the reconstructed data was successfully written, on each of the spare storage devices that the writing was finished on. A write complete message indicating that the reconstructed data was successfully written is received from at least one of the spare storage devices, and, a spare storage device from which a write complete message was received is accepted into the storage device array to replace the failed storage device.

摘要： An apparatus, system, and method are disclosed for predicting storage device failure. A technology descriptor module associates a technology descriptor with a storage device. A failure threshold module sets a predictive failure threshold for the storage device in response to the technology descriptor. In one embodiment, a workload management detection module detects workload management of the storage device. A threshold modification module may modify the predictive failure threshold in response to detecting the workload management of the storage device. A performance detection module detects a storage device error that exceeds the modified predictive failure threshold as a storage device predictive failure.

摘要： A data storage system includes a host computer, a data storage device, and a communication bus connecting the host computer to the data storage device. The host computer is adapted to issue a specialized initiation command, such as a format command with a unique parameter or a unique send diagnostic command. Once received by the data storage device, the specialized initiation command is decoded by a command processor which, in turn, directs a memory controller to execute an internal initiation of target sectors residing on data storage media within the data storage device. The memory controller places sector data in a temporary memory device, such as a random-access memory (“RAM”), including a plurality of zeroes appended to a logical redundancy check (“LRC”) value. Once compiled, this sector data is written to the data storage media. In this way, target sectors of the data storage media are initialized with LRC information without requiring large amounts of data being transmitted over the communication bus.

摘要： A bad track in a disk device in a data storage system is recovered by determining which cluster in the system the bad track belongs to. If the track belongs to the cluster that discovered that the track was bad, that cluster recovers the track by locating a good copy of the track, staging the good copy of the track to cache, and destaging the good copy of the track storage unit from the cache to all copies of the track, whether good or bad, in the data storage system. If the track belongs to another cluster, the cluster that discovered that the track was bad sends a message to the other cluster to inform it of the bad track, and the other cluster recovers the bad track. In another aspect, all tracks are owned by one server or server cluster, which performs the staging and destaging.

摘要： The present invention concerns a flexible, tubular device e.g. a bellows with an internal diameter up to 60 millimeters, said device comprising one or more corrugated convolutions (2), said convolutions having an overall bell-like shape with rounded top portions (T) and rounded bottom portions (B,B′). The novel aspects involve that the curvature of the outside surface of the convolutions (2) is numerically smaller at the top portions (T) than at the bottom portions (B,B′), said curvature being derived from a curve (6) defined as the intersection of the outside surface (4) of the device and a plane through the longitudinal axis (8) of the device, as well as they involve that the curvature of said curve changes sign only once at a change position (P,P′) located between a top portion (T) and an adjacent bottom portion (B,B″), and that the length of a first section (7) on the curve (6) is at least 10% longer than the length of a second section (9) on the curve, said first section (7) extending from one change position (P) to an adjacent change position (P′) via a top portion (T), and said second section (9) extending from one change position (P) to an adjacent change position (P′) via a bottom portion (B,B′). This provides an improved design with increased durability due to increased flexibility at lower stresses, compared to the prior art.

摘要： An apparatus and method are disclosed 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.
