Abstract: It is provided a method of managing a computer system, the computer system being configured to provide a virtual computer used by a customer, the virtual computer being coupled to a management computer configured to manage resources to be allocated to the virtual computer, the method including steps of: monitoring, by the management computer, a usage state of the resources allocated to the virtual computer; creating, by the management computer, a new allocation plan in which an amount of resources allocated to the virtual computer is reduced based on the monitored usage state of the resources allocated to the virtual computer; and creating, by the management computer, a virtual computer migration plan including the virtual computer created by the new allocation plan based on selection of the allocation plan by the customer.

Abstract: A logical volume (VOL) is provided from a storage system to a host system of a service user. A data volume reduction process is applied to data stored in the VOL. A management system determines whether at least one of a provided total capacity (provided to the service users) and a user used total volume (prior to the data volume reduction process) exceeds a storage volume capacity (upper limit of capacity of a storage space for the service provider). If so, a billing amount is calculated based on at least one amount among a first excess capacity (the difference between the user used total volume and the storage volume), a second excess capacity (the difference between the provided total capacity and the storage volume), and an amount corresponding to the service user defined as relating to at least one of the first excess capacity and the second excess capacity.

Abstract: A storage apparatus with which billing amounts in the case of write count-dependent billing can be predicted, comprises a physical storage device which provides logical volumes of different types, and a controller which executes I/O control by classifying each of the logical volumes of different types into tiers of different response performances. In a case where a write request is issued to any virtual page which configures the virtual volume, the controller assigns any real page which configures a logical volume to the virtual page, writes data to the real page, and performs a write count. The controller calculates a billing amount per fixed time interval on the basis of the performed write count, calculates tier ranges so that the billing amount per fixed time interval does not exceed the billing upper limit value, and relocates the real page on the basis of the calculated tier range.
