Transaction Processing Performance Council (TPC) Announces First Result for TPC-E Benchmark

Unisys used the On-Line Transaction Processing benchmark to measure throughput and price/performance on its ES7000/one Enterprise Server

San Francisco, July 24, 2007 — The Transaction Processing Performance Council (TPC) today announced the first result for the TPC-E benchmark. Unisys Corporation (NYSE: UIS) has used the TPC-E benchmark to measure throughput and price/performance on its ES7000/one Enterprise Server, which will be available to customers on September 28, 2007. Unisys is reporting performance of 660.85 tpsE (transactions per second for the TPC-E benchmark) and price/performance of 1,777.18 $/tpsE. Previously, Unisys had been running the TPC-C benchmark on its ES7000/one Enterprise Server systems. Unisys ran the new benchmark in the Microsoft Windows and SQL Server environment.

The TPC-E benchmark was launched in mid-March of this year and is the much-anticipated successor to TPC-C, the popular yardstick for comparing On-Line Transaction Processing (OLTP) performance on various hardware and software configurations. The primary metrics in TPC-E are performance, shown as tpsE, and price/performance shown as $/tpsE. Price is based on the purchase price of the hardware and software plus three years of maintenance.

'TPC-E provides a familiar business model that is easy to understand,' said Jerrold Buggert, director PDT Performance Group, from Unisys. 'As a result, Unisys was able to get the benchmark up and running using fewer resources than when we've run the TPC-C benchmark test in the past. TPC-E provided us with more current, realistic benchmark data that is more useful in showing how our systems can meet our customers' most intensive transaction processing requirements.'

The TPC-E benchmark models a brokerage firm with customers who generate transactions related to trades, account inquiries and market research. The brokerage firm in turn interacts with financial markets to execute orders on behalf of the customers and updates relevant account information.

TPC-E achieves a balance of disk input/output to CPU which is representative of real world OLTP environments. In comparison to TPC-C, a TPC-E configuration requires less than one-third as many disks. In addition, TPC-E requires that storage be configured to survive failures of individual storage devices, which is commonly done through RAID (Redundant Array of Independent Disks).

'TPC-E was designed both to reduce the cost and time associated with testing, and to make it more relevant to today's firms,' said Michael Molloy, TPC Chairman. 'TPC-E uses real-world data and a newer type of OLTP business model to provide benchmark results that are more meaningful and representative of the complex way customers currently use databases.'

About the TPC
The Transaction Processing Performance Council (TPC) is a non-profit corporation founded to define transaction processing and database benchmarks and to disseminate objective, verifiable TPC performance data to the industry. The TPC was established in August 1988 by eight leading software and hardware companies. The TPC currently has 20 full members: AMD, BEA, Bull, Dell, EnterpriseDB, Fujitsu, Fujitsu Siemens, HP, Hitachi, IBM, INGRES, Intel, Microsoft, NEC, Netezza, Oracle, Sun Microsystems, Sybase, Teradata and Unisys.
