SUNNYVALE, Calif. (August 31, 2007) — SGI (NASDAQ: SGIC) today announced verified test results that show SGI® Altix® to be the industry’s fastest, most scalable Linux® system for real-world, multi-tier applications running Oracle Database 10g. In fact, SGI delivered the best and only “All Linux” benchmark result with a medium-sized Oracle Database10g.

Running the Oracle E-Business Suite 11i (11.5.10) Benchmark, also known as the Oracle Applications Standard Benchmark (OASB), an SGI Altix 450 system delivered twice the performance of the previous record holder in tests that measure average response times for 2,000 online users. The SGI system also delivered record hourly throughput in Oracle’s measurement of order management and payroll batch business processes.

“For years, SGI customers have known that SGI Altix systems move data faster than any other servers in their class,” said Ken Won, director, enterprise data management, SGI. “These Oracle benchmark results offer more proof that SGI’s extensive experience in helping organizations work with big data and complex business processes is paying dividends for today’s enterprise.”

Altix performance scales as workload grows

The Oracle E-Business Suite 11i benchmark test results demonstrate the exceptional scalability of the Altix 450 system. In fact, the SGI Altix 450 actually improves as the number of users grows. At 1,400 users, Altix delivers at least 23 percent more throughput than other tested systems. The Altix advantage increases to 36 percent with 1,800 users, and reaches 40 percent with 2,000 users.

In the online test, Altix 450 retains a consistently low response time, despite the addition of hundreds of online users. For instance, as the number of users grows from 1,400 to 2,000, the average response time of the Altix 450 slows by only 12 percent , a 3X advantage over any tested system.

“SGI Altix scales where other systems fail, and this is terrific news for organizations with complex e-business environments running Oracle Database 10g,” added Won. “No other system put to these tests provides the Altix system’s blistering fast response times and high throughput. Meanwhile, SGI uniquely delivers the scalability and headroom enterprises need to meet their future needs on the same system.”

SGI’s tested configuration included:

• Database server tier: SGI Altix 450 system driven by 12 Intel® Itanium® 2 dual-core, single-threaded processors and featuring 144GB of memory and running Red Hat Enterprise Linux Advanced Server 4 (Update 4)
• Application server tier: Four SGI® Altix® XE240 servers, each powered by two Intel&3174; Xeon® dual-core processors and 16GB of memory and running Oracle Enterprise Linux
• Storage tier: SGI® InfiniteStorage 4500 system with a dual RAID controller and eight trays, each outfitted with 16, 146GB, 15K RPM drives

The results were independently audited and verified on July 25. For complete results and configurations, visit: http://www.oracle.com/apps_benchmark/html/results.html

The Oracle E-Business Suite 11i benchmark provides metrics for comparing Oracle application performance on different system configurations. It uses a mixed workload model to simulate the various transactions operating within an enterprise. The online benchmark exercises the user interface flows most frequently used by Oracle customers. The batch flow tests consist of a high-volume order processing program used to process and import orders in batch mode, and a payroll processing program used to process employee checks in batch mode.
