A storage apparatus and its control method capable of reducing load and necessary memory capacity on the side of the apparatus, which are required for management, are proposed. A role of a storage administrator, whose set of storage resources which are management objects is included in a set of storage resources which are management objects of one storage administrator or a union of sets of storage resources which are management objects of a plurality of storage administrators, is set as a first role; and in response to the first request from the management terminal used by a storage administrator who is assigned the role other than the first role, a performance information collection unit is requested to collect performance information of necessary storage resources, acquires such performance information, and the acquired performance information is transmitted to the relevant management terminal and is also stored and retained; and wherein regarding the management terminal used by the storage administrator who is determined to be assigned the first role, an instruction is issued to stop the periodic polling and the performance information is push-distributed to the relevant management terminal at a stage where the performance information of all the storage resources which are the management objects of the relevant storage administrator is acquired.

Storage apparatus and its control method

A storage apparatus includes a controller unit and output unit. The controller receives cyclic information that is cycled within a specific group of storage apparatuses with properties close to a relevant storage apparatus. The cyclic information includes performance information of each storage apparatus in the specific group and evaluation information indicative of an evaluation result of the performance information of each storage apparatus. The controller acquires the performance information including the evaluation results, combines it with the cyclic information, and transmits the cyclic information to a storage apparatus which is a next cycling destination. A similarity level may be calculated based on configuration information and a predetermined weight. A specific group may be formed by checking whether storage apparatuses are capable of communicating with each other, so a cyclic path can be formed. The output unit may transmit performance information as information to be displayed on a user terminal.
