TPC Mission and Background

• The TPC is a non-profit corporation founded to define transaction processing benchmarks and to disseminate objective, verifiable performance data to the industry

• Established in August 1988 by 8 leading software and hardware companies

• Available benchmarks include:

• TPC-C: Online transaction processing (distribution centers)

• TPC-E: Online transaction processing (brokerage)

• TPC-H: Decision support for ad hoc queries

Energy Spec: Meeting industry demand

• In the past, performance and price/performance were the key criteria in data center purchasing decisions

• Energy efficiency has become another significant factor in evaluating computing hardware

• To date, the TPC has developed nine distinct benchmarks, each according to industry demand

• The Energy Specification is a continuation of the TPC’s work over the past two decades

• The Energy Specification supplements the TPC’s existing benchmarks

• It is not a stand-alone benchmark

• Adds reporting of energy consumption while running the TPC specific workload

• Adds reporting of energy consumption for subsystems.

Energy Spec: Calls for standardized metrics• Energy efficiency in the data center has become one of the top concerns for IT

“As the cost of power grows significantly, the application of energy efficiency to systems performance becomes a metric that cannot be ignored.”- IBM, Oct. 2007

“The EPA is working with interested parties to identify ways in which energy efficiency can be measured, documented and implemented in data centers and the equipment they house, especially servers.“- EPA, 2009

“Data centers perform computing functions vital to the U.S. economy, yet they require large amounts of energy to operate. To support the growing demand for processing power throughout the nation, data centers are using ever more compact and energy-intensive servers—even as the total number and size of data centers continues to increase. This is creating a serious burden on the U.S. electric grid.”-U.S. Department of Energy, April 2009

“The energy consumed by high-tech industries and institutions represents an attractive and often untapped opportunity for energy savings. Characterized by large base-loads operating 24 hours a day with energy intensities much larger than typical commercial buildings, high-tech buildings include laboratories, cleanrooms, and data centers.”-Lawrence Berkeley National Laboratory, 2009

• Metrics that measure the application of energy efficiency against systems price and performance are needed

Price, performance and power consumption

• The three most important criteria in IT purchases include:

• Performance

• Price

• Energy consumption

• Today’s complex IT environment demands that price and energy be put in perspective of the performance

• Customers are increasingly requiring that

price/performance and energy/performance

be provided for IT purchasing decisions

• A System Under Test (SUT) should be similar to a typical customer installation rather than highly tuned and customized to run a specific benchmark

• The TPC-Energy spec helps manufacturers provide energy usage measurements, which mirror what an average user of a given system will experience

• The metric requires components of the SUT to be commercially available

• The physical environment in which the test is conducted must also be comparable to a typical data center with a minimum ambient temperature of 20 C

Benchmark System Under Test (SUT)

First Publications including TPC-Energy results.

Additional Numerical Quanties

•Three results published by HP included measurements on the Subsystems•Subsystems energy consumption will vary by configuration and vendor.•Communicates where efficiencies are most beneficial•“Ready” Idle measurements are also included.

• The EMS is a TPC provided software package designed to help manufacturers reduce the cost and difficulty of implementing the TPC Energy Specification

• The EMS provides services for power instrumentation interfacing, power and temperature logging, report generation and more

• The EMS is accessible via the TPC’s Web site (www.tpc.org)

• Customers will have more comprehensive data when selecting data-processing systems

• Identify the energy consumption for vendors systems

• Understand subsystems energy as a part of the entire configuration.

• Reduce costs while reducing energy consumption

• Compare advantages of each vendors particular offerings

Energy Measuring System (EMS)

Energy Specification Summary

• The TPC’s Energy Specification is a continuation of ongoing efforts to meet the needs of a rapidly changing industry

• Customers are able to go to the TPC Web site to identify systems that meet their price, performance and energy requirements

• Systems that use less energy also have reduced cooling requirements

• Direct relationship between power usage and heat generation

• Subsystem energy reporting provides a breakdown of relative energy usage of each subsystem (Application Server, Database Server, Storage, and Miscellaneous Subsystems)

• Competitive environment to lead in best Watts / Performance will stimulate innovation.

TPC: Providing the Most Credible Benchmarks in the Industry

• TPC is the only organization that provides consistent price-performance scores

• All tests require full documentation of the components and applications under test, so that the test can be replicated

• The TPC requires an independent audit of results prior to publication

• TPC tests the whole system performance, not just one piece

• TPC is database-agnostic: Oracle, IBM DB2, Sybase, Microsoft SQL Server, MySQL, ParAccel, Exasol and others

• TPC provides cross-platform performance comparisons, a view of processor vs. real performance, technology comparisons and actual cost of performance comparisons
