Energy efficiency of data centers is a critical priority for IT managers. As energy and power costs become a significant portion of IT costs, understanding and investing in energy management has never been more important. IBM® Systems Director Active Energy Manager™, an extension of IBM Systems Director, helps you to monitor and manage the power usage of systems. Originally designed to support IBM BladeCenter® and System x™, Active Energy Manager now supports the power management of additional IBM systems, including POWER6™ processor-based systems, as well as storage devices through the intelligent Power Distribution Unit (PDU+).
Active Energy Manager can effectively monitor and control power in the data center at the system, chassis, or rack level. By enabling these power management technologies, data center managers can more effectively power manage their systems while lowering the cost of computing.
Active Energy Manager helps determine the proper power allocation for each system in the data center. It can assist in determining how to allocate power to existing systems more efficiently so that additional systems can be accommodated without the need for additional power and cooling. When power is constrained, chargeable optional features of Active Energy Manager allow power to be rationed on a system-by-system basis, enabling available processing power to match current workload closely.
This IBM Redpaper publication is intended for system administrators to help them effectively monitor and manage the power usage of systems in a data center. This paper introduces energy management concepts and technologies and then provides a step-by-step guide to planning for, installing, configuring, and using Active Energy Manager.
