Power monitoring, metering, and billing are the new realities for data centre operators. Since there is a finite amount of power in data centres, greening may be achieved through better power utilization, and reducing power consumption. Thus it is critical for data centres to implement a power monitoring, metering and usage based billing solution: * You cannot manage what you cannot measure – usage based power monitoring will provide the information required to effectively manage data centre power capacity. * A power inventory system will increase power efficiency through effective power allocation. Every available VA of power must be utilized productively, and matched against power inventory. * “Right sizing” your HVAC & power infrastructure against available power capacity to minimize capital expenditures, and deliver the lowest cost per VA * “Green” data centres by encouraging users to conserve available capacity by billing on power usage. Usage based billing will encourage users to adopt “green” initiatives such as; turning off under utilized servers, server virtualization, turning on power saving features and so on.
