20080201527 | Data Processing System and Storage Subsystem Provided in Data Processing System - A first storage subsystem | 08-21-2008 |
20100169598 | REMOTE STORAGE DISK CONTROL DEVICE AND METHOD FOR CONTROLLING THE SAME - A storage device system includes an information processing device, a first storage device equipped with a first storage volume, and a second storage device equipped with a second storage volume. The information processing device and the first storage device are communicatively connected to one another. Also, the first storage device and the second storage device are communicatively connected to one another. The information processing device is equipped with a first write request section that requests to write data in the first storage device according to a first communications protocol, and a second write request section that requests to write data in the second storage device according to a second communications protocol. The information processing device creates first data including a first instruction to be executed in the second storage device. | 07-01-2010 |
20110106766 | REMOTE COPY SYSTEM - Provided is a remote copy system capable of guaranteeing the time ordering of data to be handled by a remote site even when the tasks at the remote site are operated across a plurality of storages or a plurality of volume groups. A consistency group consisting of a secondary journal volume and a replica is associated with a journal group consisting of a primary data volume, a primary journal volume, a secondary journal volume, and a secondary data volume. Upon backing up a secondary data volume and forming a replica, the host system issues a backup time reservation command to a storage apparatus, and the storage apparatus creates a replica by comparing the time stamp added to the journal data and the backup reservation time. | 05-05-2011 |
20110196825 | STORAGE SYSTEM AND DATA DUPLICATION METHOD IN THE SAME - A storage system has a primary storage device for storing data from host devices, and first and second secondary storage devices. When either the primary storage device or the first secondary storage device is in the process of maintenance and a failure occurs in the other secondary storage device data received from the host device is not lost, and the processing continues from the relevant data. The host device processor makes the first and second secondary storage devices perform a resync processing with reference to a relevant trigger that the respective status of the primary device and the first secondary storage device are both changed to the Suspend status. Then an I/O control unit copies the differential data between the copy data of the first secondary volume and the second secondary volume and transfers the data from the first secondary storage devices to the second secondary storage device. | 08-11-2011 |
20110246737 | REMOTE STORAGE DISK CONTROL DEVICE AND METHOD FOR CONTROLLING THE SAME - A storage device system includes an information processing device, a first storage device equipped with a first storage volume, and a second storage device equipped with a second storage volume. The information processing device and the first storage device are communicatively connected to one another. Also, the first storage device and the second storage device are communicatively connected to one another. The information processing device is equipped with a first write request section that requests to write data in the first storage device according to a first communications protocol, and a second write request section that requests to write data in the second storage device according to a second communications protocol. The information processing device creates first data including a first instruction to be executed in the second storage device. | 10-06-2011 |

20120131272 | Data Processing System and Storage Subsystem Provided in Data Processing System - A first storage subsystem includes a first storage device and a second storage device(s). A second storage subsystem includes a third storage device and a fourth storage device. A third storage subsystem comprises a fifth storage device and a sixth storage device. The first storage subsystem generates a dataset comprising an update number expressing the update order of the first storage device and write data stored in the first storage device, stores the generated dataset in the one or more second storage devices, and transmits the data set to the second and third storage subsystems. Each of the second and third storage subsystems stores the received dataset in the third storage device or fifth storage device, reads a dataset from the third or fifth storage device according to the update number, and stores the write data within the dataset in the fourth storage device or sixth storage device. | 05-24-2012 |

A consistency group consisting of a secondary journal volume and a replica is associated with a journal group consisting of a primary data volume, a primary journal volume, a secondary journal volume, and a secondary data volume. Upon backing up a secondary data volume and forming a replica, the host system issues a backup time reservation command to a storage apparatus, and the storage apparatus creates a replica by comparing the time stamp added to the journal data and the backup reservation time. | 08-30-2012 |
20130282979 | STORAGE SYSTEM AND STORAGE VIRTUALIZATION METHOD - A storage system comprises multiple primary storage apparatuses each comprising multiple primary logical volumes, which constitute the basis of a primary virtual volume, and multiple secondary storage apparatuses each comprising multiple secondary logical volumes, which constitute the basis of a secondary virtual volume forming a remote copy pair with the primary virtual volume, wherein the primary storage apparatus remote-copies data written in a primary logical volume of the relevant primary storage apparatus to a secondary logical volume of any secondary storage apparatus of the multiple secondary storage apparatuses corresponding to the write destination of this data. | 10-24-2013 |
