For the past one hundred years businesses grew their electricity consumption with little consideration for generation constraints, cost and environmental impact. The model of constant growth worked in a world of boundless cheap energy coupled to free green house gas emissions. The world's ecological limits are starting to show signs of stress. With energy and environmental constraints in mind, Cisco has developed a solution that makes the network a control plane for energy management. Cisco EnergyWise enables the network to not only monitor and control directly connected PoE devices but also other network attached AC main's powered plug loads. Cisco EnergyWise makes the network a control plane for energy management and it gives IT organizations a tool for managing energy more effectively. This session will give insights into how Cisco EnergyWise contributes to increasing energy efficiency, sustainable Green IT and Business Operations and Business behavior changes. The session will explain the current possibilities to manage and control power consumption on shipping Cisco products and attached devices and will discuss the cost saving associated with power control. Finally, the session will provide information about current upcoming industry standards and initiatives to enhance energy efficiency in network equipment as well as Cisco's newest framework to manage and optimize power consumption.
