A storage apparatus is configured to detect a connection from a new host system having no logical unit assigned thereto. The storage apparatus assigns, if any new host system is detected, a new logical unit to that new host system. By so doing, it is possible to generate a logical unit and associate it with a relevant host system whenever a storage apparatus is introduced or a new host system is added, without input from a storage apparatus administrator at a management console. It is thus possible to simplify the storage apparatus settings required whenever a storage apparatus is introduced or a new host system is added.

A home storage (a first storage device) installed in each home is provided with an area for a user to store data (user area) and an area for storing ads (ad area). The first storage device checks interest and favorite information for the user in the user area, and transmits the interest and favorite information at the same time backup is performed in a second storage device at a remote site. The second storage device selects a suitable ad based on the interest and favorite information from the first storage device and transmits the selected ad to the first storage device. The user views the transmitted ad when viewing content in the first storage device. The user's viewing record for the ads is kept as statistical data, and the second storage device compiles the record, charges a sponsor an ad charge, thereby subsidizing the usage charge for the first storage device regardless of online or offline connection.

Provided is a computer system including: a client computer; a storage system coupled to the client computer via a network; a folder deciding module; and a file storage module, in which each of a plurality of files is stored in one of a plurality of folders; the client computer receives an instruction to store a file; the folder deciding module judges how strongly the plurality of folders are each related to the designated file based on a matching degree between each of the plurality of files stored in the plurality of folders and the designated file; and the file storage module stores the designated file in one of the plurality of folders that has been judged to be most strongly related to the designated file. According to this invention, a created file is stored in a suitable folder so that the file can easily be found by the user.

Upon receiving a primary/secondary switching command from a secondary host system, a secondary storage control device interrogates a primary storage control device as to whether or not yet to be transferred data that has not been remote copied from the primary storage control device to the secondary storage control device is present. In the event that yet to be transferred data is present, the secondary storage control device receives yet to be transferred data from the primary storage control device and updates a secondary volume. The primary storage control device then manages positions of updates to the primary volume due to host accesses to the primary volume occurring at the time of the secondary storage control device receiving the primary/secondary switching command onwards using a differential bitmap table.

A method for handling a remote copy request in a distributed storage includes providing a plurality of primary volumes within a primary storage system that is coupled to a primary host via a first network, the primary storage system being coupled to a secondary storage system via a second network. A first request is selected from a plurality of requests placed in a queue based on priority information associated with the requests. A first path group is selected from one or more path groups that could be used to transmit the request. The first request is transmitted to the secondary storage system using the first path group, the secondary storage system including a plurality of secondary volumes that are paired to the plurality of primary volumes.
摘要:
A method of collecting information about data and data handling processes from different types of applications in the context of a storage system is described. The retrieved information is presented to the user to illustrate the relationships among the data, for example, in the form of a data view illustrating the relationship among files, a storage view, illustrating the physical location at which the stored data is located, or a path view illustrating a particular path through the topology of the overall computing system and storage system. Also described are techniques for assuring the accuracy of backed up files.

This storage controller providing a volume for storing data transmitted from a host system includes a management unit for managing the data written in the volume with a first block area, or a second block area in the first block area which is smaller than the first block area; a snapshot acquisition unit for acquiring a snapshot of the volume at a prescribed timing; and a transfer unit for transferring the data of the volume acquired with the snapshot of the snapshot acquisition unit to an external device with the first block area or the second block area.
摘要:
A highly advantageous storage system and a snapshot management method. In the storage system, write target data sent from a host computer to a first storage controller is duplicated and stored in the first storage controller and also in a second storage controller; when the first storage controller receives a request from the host computer to create a snapshot in the second storage controller, it suspends transferring differential data to the second storage controller, creates a new first snapshot, and transfers differential data for the created first snapshot together with the untransferred differential data for a previous first snapshot for which transferring had been suspended, to the second storage controller.

摘要:
A storage system, method and system for storing an original file and at least one format converted file of the original file. The storage system includes a storage medium and a file conversion unit which, in response to a request to store an original file, converts the original file to at least one format converted file. The file conversion unit alternatively could be external of the storage system forming a storage system. The storage system stores the original file and the at least one format converted file on said storage medium and manages a relationship between the original file and the format converted file to permit retrieval of either of the original file and the format converted file.
