• The First IBM POWER5 server in a high-density 1U package
• Ideal for infrastructure and clustered HPC workloads
• Capability to support Linux and UNIX applications simultaneously
• Three-year warranty coupled with security and reliability features to help give peace of mind
• Easy to acquire, deploy, integrate and manage.

In today's competitive world, the difference between winning and losing could be determined by how efficiently a company, be it large or small, manages its servers. That's why IBM has developed the System p5 Express family of flexible, affordable servers designed with exceptional security and reliability features and built on the successful heritage of the IBM p5 Express product line. As the lowest cost member of the System p5 Express family, the p5-505 Express entry server is built with proven POWER5 technology and provides exceptional value in a 1U (one EIA Unit) high-density system. It offers on demand computing without compromising availability, flexibility or security features—at a value price. In addition, the new OpenPower Edition supports popular distributions of the Linux operating system (OS) and the new AIX 5L Edition supports AIX 5L, IBM's industrial-strength UNIX OS. These technological and operational features coupled with a competitive price make the p5-505 Express server an outstanding choice for small, mid-sized and large businesses running infrastructure and clustered high performance computing (HPC) workloads.
