Patent number: 8533494Abstract: A storage system comprises a connector to which a removable module is connected. The removable module comprises a storage section for storing encryption/decryption information related to encryption and decryption of data, and/or an encryption/decryption engine for encrypting/decryption data by a predetermined encryption/decryption scheme. A control section and/or a module of the storage system encrypts data using the encryption/decryption information, or decrypts encrypted data using the encryption/decryption information. Alternatively the encryption/decryption engine encrypts data or decrypts encrypted data.Type: GrantFiled: January 4, 2008Date of Patent: September 10, 2013Assignee: Hitachi, Ltd.Inventor: Akitatsu Harada

Publication number: 20110238625Abstract: Provided is an information processing system including a plurality of nodes 3 and a plurality of storages 4 coupled subordinately to each of the nodes 3, each of the nodes 3 functioning as a virtual file system that provides a client 2 with storage regions of each of the storages 4 as a single namespace. This information processing system is further provided with a backup node 10 and a backup storage 11 coupled subordinately to the backup node 10. The backup node 10 synchronizes and holds location information (file management table 33) held by each of the nodes 3. Then, the backup node 10 creates a backup file, and stores the backup file in the backup storage 11 by accessing a location identified by the location information (file management table 43) synchronized and held by the backup node 10 itself to acquire a file.Type: ApplicationFiled: December 22, 2008Publication date: September 29, 2011Applicant: Hitachi, Ltd.Inventors: Masaki Hamaguchi, Akitatsu Harada, Kyosuke Achiwa

Patent number: 7529954Abstract: A control method of controlling an information processing apparatus including a CPU, a memory, and an input unit. The memory stores virtual configuration information including setting information of the storage device. The memory stores information indicating whether a management mode as a control method of the configuration information is a first mode or a second mode. The control method of the apparatus includes the steps executed by the CPU of receiving a setting instruction of the configuration information from the input unit, updating the virtual configuration information according to the setting instruction when the memory stores information indicating that the management mode is the first mode, storing the setting instruction to update the virtual configuration information, transmitting the setting instruction from the memory to the storage device, and transferring the setting instruction to the storage device when the memory stores information indicating that the management mode is the second mode.Type: GrantFiled: August 9, 2006Date of Patent: May 5, 2009Assignee: Hitachi, Ltd.Inventor: Akitatsu Harada

Patent number: 7526627Abstract: In the present invention, memory resources are effectively utilized by virtualizing external memory resources as internal memory resources, and erroneous operations that destroy the cooperative relationship of these memory resource and the like are prevented in advance. An external storage 2 is connected to a main storage 1, and real volumes 2A1 and 2A2 are respectively mapped into virtual volumes 1B1 and 1B2 (S1). The control server 3 respectively acquires construction information 1D and 2D for the respective storages 1 and 2, and stores and controls this construction information in a storage part 3D (S2). When the user inputs operation contents 4A from a control terminal 4 (S3), the control server 3 judges whether or not the operation contents 4A have an effect on the cooperation between the storages 1 and 2 on the basis of the operation contents 4A and the information in the storage part 3D (S4), and performs only operations that do not have an effect (S5).Type: GrantFiled: January 5, 2005Date of Patent: April 28, 2009Assignee: Hitachi, Ltd.Inventor: Akitatsu Harada

Publication number: 20080016311Abstract: A computer, which manages a SAN/NAS system, comprises a configuration information acquisition part, and a configuration association part. The configuration information acquisition part respectively acquires NAS host configuration information managed by a NAS host, and storage configuration information managed by a storage system. The configuration association part retrieves from storage configuration information a second information element, which conforms to a first information element in SAN host configuration information, and associates the retrieved second information element to the first information element.Type: ApplicationFiled: August 28, 2006Publication date: January 17, 2008Inventor: Akitatsu Harada
