摘要： A method for allocating resources of a storage system including at least a first and second group of storage devices. The method identifies a first set of resources to be reserved for use by the first group of storage devices, identifies a second set of resources to be reserved for use by the second group of storage devices, and identifies a third set of resources The method then allocates resources from the third set of resources to the first group of storage devices or the second group of storage device according to an allocation algorithm, and restricts use of the first set of resources to the first group of devices and use of the second set of resources to the second group of devices.

摘要： A method of managing data in a cache memory storage subsystem upon a cache write operation includes determining a first number of non-contiguously written sectors on a track in the cache and comparing the first number with a second, threshold number. If the first number exceeds the second number, a full background stage operation is issued to fill the non-contiguously written sectors with unmodified data from a storage medium. A corresponding system includes a cache manager module operating on the storage subsystem. Upon a determination that a cache write operation on a track has taken place, the cache manager module determines a first number of non-contiguously written sectors on the track, compares the first number with a second, predetermined threshold number, and issues a background stage operation to fill the non-contiguously written sectors with unmodified data from a storage medium if the first number exceeds the second number.

摘要： A Redundant Array of Independent Disks (RAID) controller receives new data that is to be written, wherein the new data is indicated in blocks of a first block size. The RAID controller reads old data, and old parity that corresponds to the old data, stored in blocks of a second block size that is larger in size than the first block size. The RAID controller computes new parity based on the new data, the old data, and the old parity. The RAID controller writes the new data and the new parity aligned to the blocks of the second block size, wherein portions of the old data that are not overwritten by the RAID controller are also written to the blocks of the second block size.

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： 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.

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 method, system, and article of manufacture for recovering from a track format error detected by a host computer associated with a storage controller associated with a storage disk array. The recovery method begins with saving a copy of the track format information associated with the data track that triggered the track format error in a predetermined location. Next, the track format information associated with the data track that caused the error is invalidated and the subject data is restaged. Subsequently, the restaged data is compared to the saved copy of the track format information to determine if the track format error exists with respect to the restaged data. If the track format error is detected with respect to the restaged data, the method further consists of reconstructing the data, preferably by performing a reconstruct read recovery. The reconstructed data is then compared to the saved copy of the track format information to determine if the track format error exists with respect to the reconstructed data. The method is completed by rebuilding the track format information to match the reconstructed data, writing the reconstructed data to the storage disk array, and passing the reconstructed data to the host.
