    摘要: A method and a system for implementing the method are disclosed relating to archival storage of information in large numbers of disk units. The reliability of the stored information is checked periodically using data verification operations whose results are saved. These results establish the veracity of the data and enable compliance with various regulatory requirements. The techniques described enable the use of low cost disk drive technology, yet provide high assurance of data veracity. In a typical system, management information storage is provided in which data entries are associated with each of the disk drives to provide information with respect to the condition of the data on that drive and its last verification. The data verification operations are performed on the data during time periods when I/O accesses are not required.

    摘要: The invention relates to a method of virtualizing a plurality of network storages into a single-view file system for a client and obtains information about an object's storage location without inquiring of a resource manager. The method determines a network storage that should store an object based on a hash value generated from a logical identifier for the object to be accessed. While accessing the object, the method computes the hash value for the object's logical identifier to determine a network storage that should process an access request. Consequently, the method eliminates the need to inquire the object's storage location when the access request is issued. Further, the method eliminates the need to maintain the object's storage location when the number of servers is increased or decreased, thus providing easy management.

    摘要: At least three storage devices are connected via a network to each other. Backup data is concurrently transferred from one of the storage devices, i.e., from a copy source storage device to other ones thereof, i.e., to copy destination storage devices. The amount of data transferred from the copy source storage device to each copy destination storage device is dynamically changed according to a state of a communication connection therebetween. At occurrence of a failure in the copy source storage device, necessary data can be concurrently read from the backup storage devices to restore the data in the copy source storage device at a high speed.

    摘要: In a system which includes an input-output controller provided with channel paths for receiving input/output requests from higher-rank apparatus, and an external storage controller connected to the input-output controller through the channels, the input-output controller registers input-output requests issued for the external storage devices from the higher-rank apparatus in input-output request queues and transfer one or plural ones of the channel programs registered in the input-output request queues collectively to the external storage controller, which control execution of the transferred channel programs, so that channel command words included in each transferred channel program are executed at timings which are adapted to an operation of one of the external storage devices which is to be controlled by the channel program.
