(WEB HOST INDUSTRY REVIEW) — The Transaction Processing Performance Council (www.tpc.org) has announced the first results for its TPC-Energy specification, designed to enable buyers to directly compare the energy efficiency, price and performance of different hardware architectures.
As energy costs become a significant challenge for many IT organizations, TPC-Energy results are expected to help guide data center managers in the purchase of equipment to meet their computational and financial requirements.
The TPC is a non-profit with the objective of defining transaction processing and database benchmarks, and for the dissemination of objective, verifiable performance data to the industry.
According to the TPC’s Wednesday announcement, HP (www.hp.com) published TPC-Energy results for its ProLiant DL580G7 and DL585G7 servers on all three TPC benchmarks, each reported in Watts/Work based on the a unit of time (ie. Watts/KtpmC, Watts/KQphH, Watts/tpsE, where tpm represents transactions per minute).
“Data center managers are under increasing pressure to identify best-fit hardware for their specific environments based on price, performance and energy consumption” TPC chairman Karl Huppler said in a statement. “With the addition of the TPC-Energy specification, direct comparison of all three factors across different hardware platforms is possible. HP is the first company to submit results, but we anticipate more publishes as customers begin to require this information to help them in their purchase decisions.”
The TPC-E benchmark simulates the online transaction processing (or OLTP) workload of a brokerage firm and is expressed in units of Watts per thousand transactions tpmC, TPC-C simulates the OLTP order-entry workload and is expressed in units of Watts/tpsE., and TPC-H simulates a decision support workload.
The HP ProLiant DL585 G7 performed at 5.93 Watts/KtpmC for the TPC-C metric; 9.58 Watts/KQphH at 300GB for TPC-H; and 6.72 Watts/tpsE for TPC-E. The ProLiant DL580 G7 scored 5.84 Watts/tpsE for the TPC-E.
HP’s results are currently posted on a “Top Ten” list on the TPC website, which will be updated regularly as additional results are reported.
“These HP TPC-Energy results mark the beginning of the TPC’s comprehensive approach to benchmarking transactional systems, where energy consumption versus performance is a key component in an ever-changing industry,” TPC-Energy committee chairman Mike Nikolaiev said in a statement. “This new specification is poised to become an essential tool for IT managers to compare and select technologies, and for IT vendors to better compete for the best performing, as well as the most energy efficient products.”
Approved in December 2009, TPC-Energy is the latest specification published by the TPC. Current benchmark standards under development include TPC-ETL (extract/transform/load) and TPC-Virtualization. The organization is also open to receiving feedback on the next major revision of the TPC-H benchmark, and encourages organizations interested in participating in future benchmark developments to join the TPC.
