摘要： Provided is a computer system including a first storage subsystem and a second storage subsystem. The first storage subsystem has a first storage unit and a first control unit. The second storage subsystem has a second storage unit and a second control unit. The first control unit records journals, and identifies, when data stored in the first storage unit is to be migrated to the second storage unit, which ones of the recorded journals are related to the data that is to be migrated. The first control unit chooses the identified journals one at a time in reverse chronological order, and judges whether or not the chosen journal corresponds to a data update made at some point between a current time and a time that precedes the current time by a length of a journal retention term set for the second storage subsystem.

摘要： A management system for managing an acquisition of information on multiple resources by multiple information acquisition apparatuses configured to acquire information on the multiple resources based on an information acquisition indication, is configured. The management system stores information for specifying a resource group, which is a group of multiple resources targeted for acquiring information at the same time points. The management system sends to each of multiple information acquisition apparatuses, which acquire information on multiple resources of a certain resource group, an information acquisition indication defining a timing for acquiring information from the resource of the certain resource group so that the information acquired from the multiple resources of the certain resource group are information at approximately the same time points. The information acquisition apparatus receives the information acquisition indication, and is able to acquire information on the resource of the certain resource group based on this information acquisition indication.

摘要： A storage tiered that satisfies desired performance is configured by recognizing the type and capacity of storage media of a storage apparatus, which are held by a user, and using the storage media.When adding a specified area of storage media to a storage tiered in response to a request from a host computer, a management computer: obtains storage media information, including I/O frequency of a data storage area of a volume(s) as well as performance information and structure information of the storage media, from the storage apparatus; identifies one or more storage media, which have not been allocated to any of the volumes with the I/O performance in excess of the I/O frequency, on the basis of the structure information of the storage media so that the data storage area of the volume(s), to which a specified storage in the storage tiered is allocated, would achieve a specified I/O performance target; and issues an instruction to the storage apparatus to create a storage tiered by using the identified storage media.
