4 results about "Disk array" patented technology

A method, information processing system, and computer program storage product for managing disk failures in a disk array. At least one disk in a first disk array is determined to have failed. The first disk array only accesses data by reading an entire stripe that is distributed across multiple disks in the first disk array. A number of spare disks are selected that is equal to a number of disks making up the first disk. A second disk array is created from the number of disks that has been selected. Data is acquired from the first disk array by reading at least one entire stripe from the first disk array. A corresponding stripe comprising the data from each respective stripe that has been acquired is written to the second disk array.

The invention discloses a storage system for a network communication recording device of a digital substation. The storage system comprises a main controller board module, a hard disk pack module and an IPMI (Intelligent Platform Management Interface) module, wherein the main controller board module is provided with an embedded processor, dual memories and an operation accelerator chip; software system modules are arranged in the dual memories; an operation system module of each software system module is used for running an guiding and loading program for the embedded processor, driving an embedded Linux operation system and introducing a Rootfs file system; a monitoring module is used for monitoring system operation, network link, chip temperature and voltage data of a module and providing the data to the outside through an IPMI specification; a storage control module is used for establishing, removing, restoring, reestablishing and monitoring a disk array of the hard disk pack module, carrying out operation management through a WEB management interface module and realizing NAS (Network Attached Storage) management and IPSAN (Internet Protocol Storage Area Network) management through a data access management module; a data tamper preventing module is used for preventing data from being illegally tampered; and the hard disk pack module is an RAID (Redundant Array of Independent Disk) 0/1/5/6 type disk array; and the IPMI module is used for monitoring the operation condition of the storage system and exporting monitoring data according to the IPMI specification.

The present invention provides a method for rapidly extracting land observing satellite scene data from a magnetic tape. According to the method, before 0-class stripe data is filed to a magnetic tape library from an online disk array, firstly, each track of data is preprocessed to generate a header file and an auxiliary data file, and data description zone content and auxiliary data are respectively stored into the two files of the disk array; and when the scene data in the 0-class stripe data needs to be recovered from the magnetic tape, the scene image data can be positioned according to the content of the header file and the auxiliary data can be directly read from the auxiliary data file. The scene data extracting task can be completed only by positioning the magnetic tape once; the problem of time delay caused by repeated positioning on the magnetic tape is solved; and near-line scene data extracting speed is increased.
