Abstract: In a network system, a storage configuration information of a storage resource as a data storage destination and a VM resource information related to a VM as storage resource allocation destination are gathered so as to provide storage resources matching the VM characteristics to the VM. Then, based on the gathered storage configuration information, storage areas corresponding to storage tiers having different characteristics are formed, and the storage tier of the storage area allocated to the VM via the VM resource information is specified.

Abstract: A storage control system including an overlap retrieval arrangement for retrieving overlap files, which are stored in at least one storage area of a plurality of storage areas, and which overlap one another, and a storage controlling arrangement for storing data of at least one overlapped part of the retrieved overlap files in a storage area having reliability that is greater than that of the storage area in which the data of this overlapped part is stored. A large number of files are stored in a plurality of storage areas, and the overlap retrieval arrangement retrieves overlap files from among a number of files, which is smaller than the number of stored files.

Abstract: Proposed are a storage system, data processing method and storage apparatus capable of performing stable data I/O processing. Each of the storage apparatuses configured in the storage group stores group configuration information containing priority information given to each storage apparatus, and the storage apparatus with the highest priority becomes a master and performs virtualization processing and data I/O processing, and another storage apparatus belonging to this storage group performs internal processing of the storage group.

Abstract: A storage system has a host system and a storage apparatus. The storage apparatus includes a first volume and a second volume to store files transmitted from the host system. The host system has: a display unit for displaying the content of a first directory in the first volume and the content of a corresponding second directory in the second volume; and a switching unit for switching, on the display unit, between the display showing the content of the first directory and the display showing the content of the second directory. The storage apparatus further has: a searching unit for searching for the second directory based on a table having a migration path from a root directory to the first directory in the first volume stored therein; and a transmitting unit for transmitting the content of the second directory, which is searched for by the searching unit, to the host system.

Abstract: A storage control system comprising overlap retrieval means for retrieving overlap files, which are stored in at least one storage area of a plurality of storage areas, and which overlap one another, and storage controlling means for storing data of at least one overlapped part of the retrieved overlap files in a storage area having reliability that is greater than that of the storage area in which the data of this overlapped part is stored. A large number of files are stored in a plurality of storage areas, and overlap retrieval means retrieves overlap files from among a number of files, which is smaller than the number of stored files.

Abstract: In a storage network system, a Frame relay device contains a cache memory for storing read data read from a storage device. The storage apparatus, when receiving a read request from a host machine, carries out processing of sending the data to the Frame relay device with addition of instructions for storing the data therein and when the read request is made to the same data again, processing of instructing the Frame relay device to send the data to a specified host machine. The Frame relay device carries out processing of sending the data stored in itself to the specified host machine.
