Rising power and cooling costs have made energy efficiency a strategic concern for data center managers. To help organizations lower total cost of ownership (TCO) and create a strategy for continuing growth. It's no small matter. Power supplies can account for as much as one fifty of the wasted power in data center server.

The organization has to addressing the energy efficiency at every level from component and server design to the overall data center infrastructure. Although data center management have the flexibility to choose many different system components to strike the most advantageous balance of performance and energy efficiency, power supply options have been limited.

In an ongoing effort to optimize energy usage in the data center, identify the power suppliers along with fans, memory and processors as the components that typically consume the most energy within a server. From the analysis result, we can see that 20 percent of power loss in a typical data center server can be attributed to inefficient power supplies.

To delivering the cost effective, the organization has to priority to reduce power loss and improve energy efficiency in power supplies. There is few key power supply manufactures such as Delta Electronics, Artesyn Technologies and Astec power help to improve power supply designs and move power supply technology forward.

Understanding Power supply specifications

When systems engineers specify the power supply requirements for an enterprise class server, their approach is similar to that a civil engineer designing a tunnel. Even though most traffic passing through the tunnel may be cars, the tunnel must be able to accommodate the largest trucks on specify a single power supply for each server based on maximum system configuration and load requirements.

Theoretically, system engineer could utilize a different power supply for each server configuration but designing to multiple power supply specifications could be cost-prohibitive. When it comes to power supply design, balancing cost, performance, and efficiency is an ongoing change.

The goal for systems engineers is to specify a single maximum power supply output rating that can handle a wide variety of configuration options and load requirements.

Meeting the power requirements of a flexible, configurable enterprise class server while improving energy efficiency requires a fundamental shift in power supply design specifications. When it comes to efficiency, a power supply may be likened to an internal combustion engine. Like an idling car burning fuel at a stop light, a power supply uses some energy just to operate.

Toward the goal of green in IT, hybrid technology is the main focus of most of the organization.

Dell is one of the MNC that working toward a goal to arching over 80 percent efficiency throughout the power supply output range to help minimize energy loss regardless of server configuration or workload.

Benefiting from power efficiency in the data center and beyond

Data Center optimizing power supply efficiencies throughout load ranges with effective designs and materials can help minimize power loss in data center server and contribute to reduced power and cooling requirements in the data center as a whole.
