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 |

20110252214 | MANAGEMENT SYSTEM CALCULATING STORAGE CAPACITY TO BE INSTALLED/REMOVED - A storage apparatus coupled to a host device comprises a virtual volume which is a virtual logical volume configured of multiple virtual areas and a pool configured of multiple actual area groups of different performances. A controller manages pool status information which is the information showing which actual area is allocated to which virtual area and access load related to the virtual areas. A management system of the storage apparatus, with reference to the pool status information at multiple points of time from past to present and an access load threshold which is equal to or larger than 1, estimates the used capacity of each actual area group at points of time in the future, calculates the installed/removed amount of each actual area group which is the difference between the estimated used capacity and the current storage capacity, and performs the processing based on the calculated result. | 10-13-2011 |
20110258407 | STORAGE SYSTEM AND MANAGEMENT METHOD THEREOF - A storage system having at least two storage apparatuses capable of partitioning an internal resource into logical partitions and managing the logical partitions, and which replicates data written into a primary volume of a primary storage apparatus as the replication source storage apparatus to a secondary volume of a secondary storage apparatus as the replication destination storage apparatus, including: a configuration information sending unit for sending configuration information of the logical partition, to which the primary volume belongs, to the secondary storage apparatus; and a logical partition setting unit for setting the configuration of the logical partition to which the secondary volume belongs based on the configuration information of the logical partition to which the primary volume belongs sent from the configuration information sending unit. | 10-20-2011 |
20120144002 | CLUSTER STORAGE SETTING METHOD, SYSTEM, AND MANAGEMENT SYSTEM - A storage cluster including a first storage apparatus and a second storage apparatus is defined. Communication between the first storage apparatus and the second storage apparatus uses a first network and an access request from a host computer uses a second network. Each of the first and second storage apparatuses defines internal LUs by using storage devices included in that storage apparatus. The first storage apparatus defines other internal LUs by using internal LUs of the second storage apparatus and the second storage apparatus defines other internal LUs by using internal LUs of the first storage apparatus. | 06-07-2012 |
20120144112 | MANAGEMENT COMPUTER AND VOLUME CONFIGURATION MANAGEMENT METHOD - The configuration of volumes provided by a plurality of storage apparatuses with an external connection function is optimized. | 06-07-2012 |
20120191941 | STORAGE SYSTEM AND MANAGEMENT METHOD THEREOF - A storage system having at least two storage apparatuses capable of partitioning an internal resource into logical partitions and managing the logical partitions, and which replicates data written into a primary volume of a primary storage apparatus as the replication source storage apparatus to a secondary volume of a secondary storage apparatus as the replication destination storage apparatus, including: a configuration information sending unit for sending configuration information of the logical partition, to which the primary volume belongs, to the secondary storage apparatus; and a logical partition setting unit for setting the configuration of the logical partition to which the secondary volume belongs based on the configuration information of the logical partition to which the primary volume belongs sent from the configuration information sending unit. | 07-26-2012 |
20120216005 | STORAGE SYSTEM AND MANAGEMENT METHOD OF THE STORAGE SYSTEM - Even if no port of the attribute communicable with communication ports which the other storage control apparatuses comprise exists among the communication ports which the storage control apparatus comprises, connecting the respective storage control apparatuses as communicable. | 08-23-2012 |
20130036266 | FIRST STORAGE CONTROL APPARATUS AND STORAGE SYSTEM MANAGEMENT METHOD - An object of the present invention is to allocate a volume to an appropriate tier in a pool in accordance with the performance of the volume. Multiple tiers | 02-07-2013 |
