    摘要： 【課題】情報処理装置に二次記憶装置として搭載される記憶装置のタイプに合わせて、情報処理装置の省電力化のための電力制御を実行できるようにする技術を提供する。 【解決手段】情報処理装置(MFP)のCPUは、MFPが備えている二次記憶装置の装置情報を取得し(S101,S102)、取得した装置情報に基づいて、二次記憶装置が、省電力状態への移行回数が当該記憶装置の寿命に影響するタイプの記憶装置であるか否かを判別する(S103)。更に、CPUは、二次記憶装置のタイプの判別の結果に従って、二次記憶装置が省電力状態へ移行するための移行条件として、当該二次記憶装置が省電力状態へ移行するための移行時間を決定する(S104)。CPUは、省電力状態への移行回数が寿命に影響しないタイプの記憶装置(SSD)の移行時間を、当該移行回数が寿命に影響するタイプの記憶装置(HDD)の移行時間よりも短く決定する。 【選択図】図2

    摘要： A power consumption controller includes an input power monitoring unit, a load information monitoring unit, a redundancy configuration unit and a power control unit. The input power monitoring unit monitors an input power to a unit including a plurality of components. The load information monitoring unit measures a load of each of the components. The redundancy configuration unit stores information regarding an operation state of each of the components and extracts information regarding a configuration in which redundancy is maintained even if one of the components in operation is stopped. The power control unit detects whether or not the input power is over a predetermined value, selects a component having the smallest load among the components of the extracted configuration when the input power is over the predetermined value and switches the selected component into a power saving mode.

    摘要： An information processing apparatus includes a plurality of storage units, a mirroring control unit configured to execute mirroring processing, which includes writing processing for writing same data on each of the plurality of storage units and reading processing for reading data from either one of the plurality of storage units, and a power control unit configured to independently control supply of power to the plurality of storage units. If the supply of power to the plurality of storage units is reduced, if the mirroring control unit starts the writing processing, the information processing apparatus resumes the power supply to the plurality of storage units, and if the mirroring control unit starts the reading processing, the information processing apparatus resumes the power supply to a specific storage unit from which the data is read, and configured to execute control not to resume the power supply to the other storage unit(s).

    摘要： The controller specifies a first VVOL that is a virtual volume of an electrical power saving target and a first RG that is a RAID group of an electrical power saving target. The controller judges whether or not there is a first real area that is allocated to a second VVOL that is a virtual volume other than the first VVOL and that is a real area based on the first RG. In the case in which the result of the judgment is positive, the controller moves data in the first real area to a free real area based on a second RG that is a RAID group other than the first RG, and executes a first moving processing in which a real area of a moving destination as substitute for a first real area to a virtual area to which the first real area is allocated. The controller sets all of physical storage devices that configure the first RG to be in an electrical power saving state in the case in which there is not real area that is allocated to a second VVOL as a real area based on the first RG.
