IBM System z9 Enterprise Class: A security-rich, resilient and scalable mainframe for managing on demand infrastructures

For over four decades, the IBM mainframe has been a leader in data and transaction serving. Our announcement of the IBM System z9 109 (z9-109) in July of 2005, provided a strong combination of mainframe characteristics plus new functions designed around scalability, availability, security, and virtualization. With today′s announcement, the z9-109 will be known as the System z9 Enterprise Class (z9 EC) and we continue that leadership with the introduction of new capacity settings with subcapacity central processors, the hardware availability of our new IBM System z9 Integrated Information Processor (IBM zIIP), and continue to help improve our FICON performance and throughput.
