Abstract: Protected data is divided into a plurality of segments. For each segment in the plurality of segments, a fingerprint is generated. The plurality of fingerprints is grouped into group(s) of fingerprints and for each group of fingerprints, a group fingerprint is generated. It is determined if the group fingerprint being processed is stored in a cache and if so, the group fingerprint being processed is flagged as one for which a virtual copy will be performed.

Abstract: Described are techniques for processing a data request for a device of a data storage system. A data request directed to a device that is a virtualized device of the data storage system is received. The data storage system has a plurality of devices comprising one or more local devices and one or more virtualized devices. Each of the local devices is a storage device included in the data storage system and each of the virtualized devices is an external storage device with respect to the data storage system and is presented as a local storage device of the data storage system. First processing is performed by a disk adapter in connection with servicing the data request for the device. The first processing includes sending the request to an external storage device corresponding to the virtualized device over a connection in accordance with path information obtained from discovery processing.

Abstract: Described are techniques for processing a data operation in a data storage system. A front-end component of the data storage system receives the data operation. In response to receiving the data operation, the front-end component performs first processing. The first processing includes determining whether the data operation is a read operation requesting to read a data portion which results in a cache miss; and if said determining determines that the data operation is a read operation resulting in a cache miss, performing read miss processing. Read miss processing includes sequential stream recognition processing performed by the front-end component to determine whether the data portion is included in a sequential stream.

Abstract: Described are techniques for performing data migration for a source logical volume and a target. The target is configured as storage for another mirror of the source logical volume prior to copying data from the source logical volume to the target, and if the target is configured storage of another logical volume of the data storage system, the configured storage is remapped as storage for another mirror of the source logical volume prior to copying data from the source logical volume to the target. One or more invalid bits are set indicating that the target does not contain a valid copy of data from the source logical volume. Data is copied from the first mirror of the source logical volume to the target. Invalid bits are cleared as data portions of the first mirror of the source logical volume are copied to the target.

The accuracy of ranging is increased through multi classes of receiving process; the accuracy of ranging is further increased through the selection of distance mode and the adjustment of receiving sensitivity before the measuring steps are executed; the accuracy of ranging is further increased through executing jitter judgment on obtained distance measured values to discard the distance measured values that do not satisfy the setting conditions and judge whether the number of remaining distance measured values satisfies the setting quantity requirement; and the present invention is also of simple structure, high measurement efficiency, and low power waste.

Abstract: Described are techniques for representing and using RAID group consistency information. RAID group consistency information for a slice of data included on a device may be obtained by mapping the slice to an index. The index is one of a plurality of indices each associated with a structure indicating RAID group inconsistencies for a different portion of slices of data of the device. If the index is not associated with a structure, it may be determined that there is no RAID group inconsistency for the slice. If the index is associated with a structure, a hint bit associated with the slice may be determined wherein the hint bit encodes summary consistency information for a plurality of slices. A determination is made as to whether the hint bit is set, and, if the hint bit is not set, it is determined that there is no RAID group inconsistency for the slice.

Abstract: Described are techniques for determining where to store data and parity information in a RAID group for a data track having a track number. A stripe number is provided. A first member identifier is determined which identifies a RAID group member at which data information of said data track is stored. A second member identifier of a second member of said RAID group is determined to store a first set of parity information for said data track. A third member identifier of a third member of said RAID group is determined to store a last set of parity information for said data track. It is determined whether the third member identifier is less than the second member identifier. If the third member identifier is less than said second member identifier, the first member identifier is updated. Also described are techniques for determining a track identifier of a data track stored at a location in a RAID group.
