20090097655 | Storage system and storage system management method - An object of the present invention is to prevent data from being tampered with, and to prevent operation mistakes, when sending and receiving data between a management software managing storage devices. | 04-16-2009 |
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 |
20110208940 | Storage system and method for operating storage system - In a storage system | 08-25-2011 |
20110231711 | STORAGE SYSTEM AND KNOWN PROBLEM INFORMATION MANAGEMENT METHO - Proposed are a highly reliable storage system capable of inhibiting the problematic operation or change of state in the [storage] system, and a known problem information management method capable of improving the reliability of the storage system. The storage system is provided with a storage apparatus including a storage medium for storing data, and a management apparatus for managing the storage apparatus. The management apparatus includes an apparatus-side known problem information storage unit for storing known problem information as information concerning a problematic operation or a change of state, a maintenance management terminal operation controller for receiving a user's operation or change of state and creating history information according to the operation or change of state, and an apparatus-side known problem information search unit for searching, from the apparatus-side known problem information storage unit, known problem information corresponding to the history information, wherein the maintenance management terminal operation controller inhibits the operation of the searched known problem information. | 09-22-2011 |
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 |
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 |
20140025888 | STORAGE SYSTEM AND METHOD FOR EFFICIENTLY UTILIZING STORAGE CAPACITY WITHIN A STORAGE SYSTEM - In a storage system | 01-23-2014 |
20140244958 | STORAGE SYSTEM AND MANAGEMENT METHOD THEREFOR - A storage system comprises multiple first storage apparatuses, and a controller which provides a first logical volume corresponding to a storage area of the multiple first storage apparatuses to a host computer. The controller partitions a storage area corresponding to the first logical volume into multiple first physical storage areas, manages the partitioned multiple first physical storage areas as physical storage areas of a storage pool, creates a first virtual volume which is provided to the host computer, and associates, from among the multiple first physical storage areas, a physical storage area in which user data is stored, with the first virtual volume. | 08-28-2014 |
20150074349 | 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. | 03-12-2015 |
