20120047327 | Disk array device and control method for the same - A disk array device includes a disk group that stores therein data, and stores therein an upper limit of multiplicity capable of multiple data transfer using a line, for each line connected with a transfer destination device being a transfer destination of the data stored in the disk group. When data transfer is to be executed, the disk array device acquires the upper limit stored in association with the line connected with the transfer destination device of the data transfer. The disk array device also acquires current multiplicity of the data currently transferred through the line. When it is determined that the multiplicity does not exceed the upper limit even if the data transfer is executed, the disk array device executes the data transfer. | 02-23-2012 |

20130080569 | INFORMATION PROCESSING APPARATUS AND COMPUTER-READABLE RECORDING MEDIUM HAVING PROGRAM STORED THEREON - By generating second data transfer status managing information for managing a data transfer status between the first storing unit and a third storing unit provided in the second storage apparatus, and third data transfer status managing information for managing data transfer status between the second storing unit and a fourth storing unit provided in the second storage apparatus based on the first data transfer status managing information; and transferring data between the first storing unit and the third storing unit based on the second data transfer status managing information, transferring data between the second storing unit and the fourth storing unit based on the third data transfer status managing information, and transferring the first data transfer status managing information, the data transfer status between multiple storing units in a migrating storage apparatus may be reproduced in another migrated storage apparatus. | 03-28-2013 |
20140040581 | STORAGE SYSTEM AND DATA TRANSFER METHOD - A storage system includes: a storage device configured to copy data to another storage device, the storage device includes: a first storage region configured to store the data; a first receiving unit configured to receive a first instruction from a higher level device; a transferring unit configured to transfer the instruction from the higher level device to the another storage device; and a first storage region releasing unit configured to release the first storage region, wherein, when the first instruction is a releasing instruction instructing to release the first storage region, the transferring unit transfers the releasing instruction to the another storage device before releasing of the first storage region is completed by the first storage region releasing unit. | 02-06-2014 |
20140068233 | INFORMATION PROCESSING APPARATUS AND COPY CONTROL METHOD - The information processing apparatus includes a creating unit and a control unit. On receiving an offloaded data transfer instruction, the creating unit creates a copy session for transferring data from a transfer-source memory area of a transfer-source memory apparatus to a transfer-destination memory area of a transfer-destination memory apparatus. When detecting no overload incurred by asynchronous execution control under which the data transfer is executed out of sync with the offloaded data transfer instruction, the control unit determines that the data transfer of the created copy session is to be executed under the asynchronous execution control. On the other hand, when detecting overload incurred by the asynchronous execution control, the control unit determines that the data transfer of the created copy session is to be executed under synchronous execution control in which the data transfer is executed in synchronization with the offloaded data transfer instruction. | 03-06-2014 |
