20090094426 | STORAGE SYSTEM - An object of the present invention is to reduce the required volume capacity and journal control resources by sharing the journal volumes of an asynchronous copy function and a CDP function. | 04-09-2009 |
20090249104 | Storage system - A journal volume is created in a different power control unit of a normal mode, and the power saving mode is maintained by storing differential data in the journal until the corresponding power control unit is returned to a normal mode. A replication pair in a pair status in the power control unit is confirmed, set as a target to be switched to the power saving mode if it is of a constant value or less, and a management server is notified if there is an operation for creating a volume. | 10-01-2009 |
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 |
20100088485 | FAILURE MANAGEMENT METHOD IN THIN PROVISIONING TECHNOLOGY FOR STORAGE - A pool is replicated in the unit of volume providing the pool, and when a physical device is blocked, any volume blocked in the pool is changed to the replicated volume so that the pool and a virtual volume can be recovered. With such a configuration, when any pool or virtual volume is blocked due to blockage of any volume providing the thin provisioning function, volume recovery can be swiftly performed without changing the virtual volume used by a host computer, and consumption of storage resources needed therefor can be suppressed. | 04-08-2010 |
20100088556 | FAULT MANAGEMENT SYSTEM IN MULTISTAGE COPY CONFIGURATION - A data storing system including: a first, second and third storage systems providing first, second and third logical volumes; wherein the first logical volume and the second logical volume forms a first replication pair which indicates the first logical volume is a replication source and the second logical volume is a replication destination, and the second logical volume and the third logical volume forms a second copy pair which indicates the second logical volume is the replication source and the third logical volume is the replication destination. The replication pairs may adopt differing possible pair statuses, which may affect consistency between such pairs. | 04-08-2010 |

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 |
