HP Superdome Server Simulates Processing of One of World's Largest Payrolls in Less Than a Single Shift

Unprecedented Results Achieved Using Superdome, Oracle9i Real Application Clusters
PALO ALTO, Calif., May 5, 2003

The HP Superdome server simulated the processing of one of the world's largest payroll systems -- consisting of monthly, weekly and biweekly payroll checks for more than 2.6 million employees -- in less than four hours, according to benchmark testing conducted at HP's (NYSE:HPQ) Americas Solution Center in Cupertino, Calif.(1)

The benchmark results demonstrated that HP Superdome servers and HP StorageWorks Disk Arrays xp1024, in combination with Oracle9i Real Application Clusters, can scale to some of the largest and most complex computing scenarios for enterprise customers.

"As a leading technology company, HP realizes its customers and the industry benefit from comparing performance benchmarks," said Bruce Klein, vice president, federal sales and marketing, HP Public Sector Organization. "The results announced today prove that even with commercial off-the-shelf software, the HP Superdome server can process one of the world's largest payroll systems in less than a single shift."

"This benchmark demonstrates the performance and scalability benefits of Oracle9i Real Application Clusters for enterprise applications," said Richard Sarwal, vice president, data server applied technologies, Oracle Corporation. "And because the scalability and fault-tolerance of Real Application Clusters are achieved without requiring application changes, we see rapid adoption of this technology by enterprise ISVs."

Benchmark Specifications and Results

The benchmark was the first fully integrated test of a large government agency's personnel and pay capabilities. It simulated the final pay period of the year for an organization with more than 2.6 million members being paid at one time. Each person had a full 12 months of payroll history.

Striving to emulate peak loads for a 24x7 operation, the benchmark simulated simultaneous batch and OLTP loads. The benchmark also included a simultaneous simulation of 76,000 end users accessing off-the-shelf human resource management systems. The self-service processes included: accessing the system via single sign-on; viewing personalized role-based home page; and completing human resource self-service transactions, performing performance evaluations, promotions and new-hire transactions.

In addition, the base population of active employees in this organization was 4.5 million. The payroll system was broken down into 128 randomly sized pay groups, ranging from 15,000 to 50,000 employees, to represent a normal enterprise distribution. Each employee had multiple benefits and deductions, including state and local tax requirements, which required the use of U.S. tax laws.

The benchmark architecture included two HP Superdome servers running HP-UX 11i, with the payroll system having 64 PA-RISC processors (750 MHz) and 128 GB of memory, while the interactive system had 32 PA-RISC processors (750 MHz) and 128 GB of memory.

The servers were clustered via Hyperfabric connectivity and HP MC/Serviceguard, using Oracle9i Real Application Clusters, so that both the interactive and the payroll users were accessing the same data simultaneously. The interactive users were emulated using Mercury LoadRunner and accessed the system via 12 HP rp2450 Web servers with two processors running WebLogic 5.1 on HP-UX 11i.

The application servers consisted of four eight-processor HP Servers rp7410 and four 16-processor HP Servers rp8400 running commercially available human resource management systems and North American Payroll 8.3 with Tuxedo version 6.5 with Jolt 1.2 on HP-UX 11i. The HP StorageWorks Disk Array xp1024 provided the enterprise-class storage capacity and performance for the benchmark.

Benchmark test results were validated by TESCOM, an industry leader in certifying benchmark results for software products. TESCOM independently re-executed the benchmark and achieved the same results as the HP Americas Solution Center, which is also used by HP customers for proof-of-concept testing (prototyping), application characterization, porting and migration, and solution demonstration capabilities.

The high-end UNIX® HP Superdome server offers customers industry-leading performance, partitioning, connectivity, availability and utility computing. Customers benefit from fast on-line transaction processing, short batch-processing windows, rich data warehousing, high-volume e-commerce/Web transactions and a solution that's easy on the IT budget.
