    摘要: A virtual storage system control apparatus, a virtual storage system control program and a virtual storage system control method can move one or more than one virtual volumes without suspending the services being provided. The virtual storage system control apparatus comprises a plurality of storage device control sections that assign virtual volumes to the storage devices of the virtual storage clusters, generate information on the virtual volumes, set up a link between the virtual volumes of the own virtual storage clusters and the virtual volumes of other virtual storage clusters by way of the network and copy data on the basis of the link and a management node that directs a move of a virtual volume by having the link set up according to the information on the virtual volumes.

    摘要: A storage apparatus connection managing apparatus, detecting upon detecting that a new storage apparatus has been connected to the computer, whether the storage apparatus includes a data area capable of storing data and a program area having preliminarily stored therein a data access program for accessing the data area of the storage apparatus and a volume management program for managing a data storage destination in an integrated manner when storing data in a distributed manner in a plurality of storage apparatuses. The apparatus reads the data access program and the volume management program from the program area of the detected storage apparatus and activates the programs in the apparatus.

    摘要: A computer-readable recording medium having recorded a hash-value generation program for calculating a hash value within a shorter period of processing time. When a target disk is specified for hash value calculation, a segment division block divides the target disk into fixed-length segments. A first hash-value calculation block applies a one-way hash function to all data in each segment to calculate a per-segment hash value. A second hash-value calculation block arranges the per-segment hash values in a segment order corresponding to the order of the data stored on the target disk and applies the one-way hash function again to the arranged per-segment hash values to calculate a total hash value. The hash value calculated in this manner is defined as a hash value of the target disk.
