SPEC Releases Server Efficiency Rating Tool (SERT)

The Standard Performance Evaluation Corp. (SPEC) has released the Server Efficiency Rating Tool (SERT), designed to help computer manufacturers develop more energy-efficient products and enable datacenters to reduce energy consumption.

SERT testing is a mandatory part of the U.S. Environmental Protection Agency's (EPA) ENERGY STAR for Servers v2.0 specification, expected to be published next month.

Improving datacenter energy efficiency

According to an EPA report, datacenters accounted for nearly three percent of total U.S. electricity consumption in 2011. The EPA and SPEC see SERT as a major tool that will help datacenters become more energy-efficient.

"We believe that this tool will provide excellent insight into server energy performance and help computing professionals better understand the energy consumption of products, which in turn will help reduce operating costs and help datacenter managers more precisely plan their future energy needs," says Robert J. Meyers, ENERGY STAR's datacenter products lead.

Simple-to-use, full-featured tool

Although SERT benefits from SPEC's extensive experience developing SPECpower_ssj2008, it differs in key ways from a benchmark. It does not provide comparative scores and is designed to test systems "as shipped," without the extensive tuning that vendors typically perform to increase benchmark test scores.

"SERT is designed to be an economical and simple-to-use tool, requiring minimal equipment and skills," says Klaus-Dieter Lange, SPECpower committee chair. "We expect it to drive more efficient solutions from server manufacturers and to provide guidance that will lead datacenter managers to better energy-related decisions."

Built on SPEC’s Chauffeur framework, major characteristics of SERT include:

  • Synthetic worklets that test discrete system components such as memory and storage, providing detailed power consumption data at different load levels.
  • Automatic collection of system configuration data with a graphical user interface to review and edit the information.
  • Automatic validation of results at both runtime and upon completion of testing.
  • Multi-threading and multiple-system runs, providing scalability across a wide range of servers.
  • Portability to various computing platforms.
  • Run-time behavior that can be changed for research purposes.
  • Results available in both machine- and human-readable forms, enabling automatic submission to government-sponsored certification programs.

Cooperative development

The SPECpower committee that developed SERT includes representatives from AMD, Dell, Fujitsu, HP, IBM, Intel and Microsoft, with veteran SPEC benchmark developers Greg Darnell, Alan Adamson and post-graduate researcher Christian Koopmann as supporting contributors. The EPA provides regular high-level policy and directional guidance to the SPECpower committee, and other organizations around the world contribute input and feedback.

Available immediately

SERT is available immediately from SPEC for $2,800. Discounts are available for qualifying non-profit research and academic organizations. SERT requires a SPEC-accepted power analyzer and temperature sensor. Visit www.spec.org/sert/ for more information.

IoT & Smart Cities Stories
The deluge of IoT sensor data collected from connected devices and the powerful AI required to make that data actionable are giving rise to a hybrid ecosystem in which cloud, on-prem and edge processes become interweaved. Attendees will learn how emerging composable infrastructure solutions deliver the adaptive architecture needed to manage this new data reality. Machine learning algorithms can better anticipate data storms and automate resources to support surges, including fully scalable GPU-c...
Machine learning has taken residence at our cities' cores and now we can finally have "smart cities." Cities are a collection of buildings made to provide the structure and safety necessary for people to function, create and survive. Buildings are a pool of ever-changing performance data from large automated systems such as heating and cooling to the people that live and work within them. Through machine learning, buildings can optimize performance, reduce costs, and improve occupant comfort by ...
The explosion of new web/cloud/IoT-based applications and the data they generate are transforming our world right before our eyes. In this rush to adopt these new technologies, organizations are often ignoring fundamental questions concerning who owns the data and failing to ask for permission to conduct invasive surveillance of their customers. Organizations that are not transparent about how their systems gather data telemetry without offering shared data ownership risk product rejection, regu...

Poor data quality and analytics drive down business value. In fact, Gartner estimated that the average financial impact of poor data quality on organizations is $9.7 million per year. But bad data is much more than a cost center. By eroding trust in information, analytics and the business decisions based on these, it is a serious impediment to digital transformation.
Digital Transformation: Preparing Cloud & IoT Security for the Age of Artificial Intelligence. As automation and artificial intelligence (AI) power solution development and delivery, many businesses need to build backend cloud capabilities. Well-poised organizations, marketing smart devices with AI and BlockChain capabilities prepare to refine compliance and regulatory capabilities in 2018. Volumes of health, financial, technical and privacy data, along with tightening compliance requirements by...
Predicting the future has never been more challenging - not because of the lack of data but because of the flood of ungoverned and risk laden information. Microsoft states that 2.5 exabytes of data are created every day. Expectations and reliance on data are being pushed to the limits, as demands around hybrid options continue to grow.

Enterprises have taken advantage of IoT to achieve important revenue and cost advantages. What is less apparent is how incumbent enterprises operating at scale have, following success with IoT, built analytic, operations management and software development capabilities - ranging from autonomous vehicles to manageable robotics installations. They have embraced these capabilities as if they were Silicon Valley startups.
As IoT continues to increase momentum, so does the associated risk. Secure Device Lifecycle Management (DLM) is ranked as one of the most important technology areas of IoT. Driving this trend is the realization that secure support for IoT devices provides companies the ability to deliver high-quality, reliable, secure offerings faster, create new revenue streams, and reduce support costs, all while building a competitive advantage in their markets.
