IBM EnergyScale for POWER7 Processor-Based Systems

The energy required to power and cool computers can be a significant cost to a business – reducing profit margins and consuming resources. In addition, the cost of creating power and cooling infrastructure can be prohibitive to business growth. In response to these challenges, IBM developed EnergyScale™ Technology for IBM Power Systems. EnergyScale provides functions that help the user to understand and control IBM server power and cooling usage. This enables better facility planning, provides energy and cost savings, enables peak energy usage control, and increases system availability. Administrators may leverage EnergyScale capabilities to control the power consumption and performance of POWER processor-based systems to meet their particular data center needs.

In this paper, the functions provided by EnergyScale are described along with usage examples, and hardware and software requirements. All POWER6 and POWER7 processor-based systems support some, if not all, EnergyScale features. All systems support IBM Systems Director Active Energy Manager, which is a comprehensive energy management tool that monitors and controls IBM Power servers. Support and awareness of EnergyScale extends throughout the system software stack, and is included in the AIX, IBM i, and Linux operating systems. This paper focuses on features and functions found in systems based on POWER7 processors. For previous-generation IBM Power systems, please refer to a companion paper, “IBM EnergyScale for POWER6 Processor-based Systems.”
