Power Assure Case Studies

A10 Networks

Extending the Life of a Data Center wth Power and Cooling Efficiencies

To help accommodate the company's rapid growth, A10 Networks needed better visibility and control of power utilization throughout its data center. Power Assure's EM/4 software provided just the Data Center Infrastructure Management platform A10 Networks needed to integrate monitoring, analysis and automation in a single, intuitive system.

Sun Microsystems hosted demonstrations of Power Assure's Dynamic Power Management and Optimization capabilities. After measuring the precise draw of Sun servers at off, idle, and 100% load, Power Assure's capacity planning functionality accurately predicted capacity in the racks, without the inaccuracies of estimates based on vendor power labels. This accuracy enables Power Assure to plan IT power needs exactly.

Once power can be predicted based on IT utilization, companies can use Dynamic Power Optimization to automatically balance server farms and associated cooling, thereby minimizing power consumption. During this study, Power Assure's software reduced power consumption by 68% in a 25% loaded server farm.

Dynamic Power Optimization: Adjusting Data Center Capacity in Real-Time

Energy Efficient Data Center Demonstration Project

The application utilization for larger server farms in today's data centers is typically highly volatile due to many factors. Time-of-day usage patterns, promotions and advertisements, and unexpected events all cause spikes in demand, both planned and unplanned. As a result, data center operators have to deal with a high level of uncertainty when planning capacity. They mitigate the risk of a service outage by over-provisioning equipment and keeping their entire pool of servers up and running.

The result is an average utilization of 10-15%, with occasional peaks of 85-90%. As exemplified in a case study performed at last year's SVLG Chill-Off, such low average utilizations result in waste of over 50% of server power consumption.

This case study used Power Assure's Dynamic Power Optimization to adjust server capacity to meet actual application loads. The results confirmed the estimated gains in efficiency, without impacting customer service levels despite real-life, highly volatile usage patterns. This case study underscores the advantages of moving data centers to an energy-proportional model.
