| 20090031320 | Storage System and Management Method Thereof - A storage system comprises a first storage apparatus having a volume for a host computer, a second storage apparatus connected to the first storage apparatus, and having a volume having a pair relationship with a first volume in the first storage apparatus, and a management apparatus connected to the first storage apparatus and the second storage apparatus. The management apparatus includes a user interface for setting an attribute of a function related to the volume of the first storage apparatus and an attribute of a function related to the volume of the second storage apparatus. The management apparatus compares the attribute of the function related to the first volume and the attribute of the function related to the second volume, and outputs the result of the comparison to the user interface. | 01-29-2009 |
| 20090300387 | OPERATION METHOD OF STORAGE APPARATUS, STORAGE APPARATUS AND STORAGE SUBSYSTEM - Proposed is an operation method for seeking a power interruption operation target in which MTBF will become longest. When a target value regarding a power interruption time and a target value regarding a power interruption count per 24 hours is input from an administrator to a management computer, the management computer calculates the MTBF after one year and the annual power consumption for each of the input target values, and, as a power interruption operation target in which the MTBF will become longest in one year, a target value regarding a power interruption time and a target value regarding a power interruption count are respectively selected among multiple target values in which the MTBF will become longest based on each of the calculation results, and displayed on a screen of an output unit. | 12-03-2009 |
| 20100036896 | Computer System and Method of Managing Backup of Data - A backup is continued in a computer system even one storage device is stopped. In the computer system, a first storage device, upon reception of a data write request to a first storage area, stores the data in the first storage area and a second storage area, and transmits the data to a second storage device. The second storage device stores the received data in a third storage area and a fourth storage area. The first storage device, upon reception of a snapshot creation request, suspends storing of the data in the second storage area, while the second storage device, upon reception of the snapshot creation request, suspends storing of the data in the fourth storage area at timing that the same data is stored in the second storage area and the fourth storage area, and after storing of the data is suspended, transmits an identifier equal to an identifier of the second storage area to an inquiry transmission source as an identifier of the fourth storage area. | 02-11-2010 |
| 20100082934 | COMPUTER SYSTEM AND STORAGE SYSTEM - In order to manage and operate Pool created in storage system A and a virtual volume using Pool in storage system B, it is required to copy the virtual volume of storage system A into a virtual volume of storage system B and new storage regions for copy of virtual volume into storage system B are needed. Storage system B acquires configuration information of Pool and a virtual volume of storage system A and inputs a logical volume included in Pool of storage system A to storage system B based on the acquired configuration information. Storage system B transforms the acquired configuration information for use in storage system B and creates Pool and a virtual volume from the input logical volume based on the transformed configuration information. | 04-01-2010 |
| 20110179188 | STORAGE SYSTEM AND STORAGE SYSTEM COMMUNICATION PATH MANAGEMENT METHOD - The present invention makes it possible to reassess respective host paths and reset priorities in accordance with the current state of a storage system. A management computer | 07-21-2011 |
| 20110296195 | STORAGE DEVICE AND ITS CONTROL METHOD - Provided is a storage device which partitions data from a host into multiple partitioned data and distributes, encrypts and stores them together with a parity to and in multiple memory mediums. This storage device executes processing of restoring the partitioned data or the parity stored in a memory medium to be subject to encryption re-key based on decrypted data of the partitioned data or the parity stored in each memory medium other than the memory medium to be subject to encryption re-key among the multiple memory mediums, storing the restored partitioned data or the parity in a backup memory medium while encrypting the restored partitioned data or the parity with a new encryption key, and thereafter interchanging the backup memory medium and the memory medium to be subject to encryption re-key so that the backup memory medium will be a memory medium configuring the parity group and the memory medium to be subject to encryption re-key will be the backup memory medium. | 12-01-2011 |
