While zSeries servers are supported by a number of dif- ferent operating systems, their most advanced features are powered by z/OS. z/OS is the foundation for the future of zSeries, an integral part of the z/Architecture designed and developed to quickly respond to the demanding qual- ity of service requirements for on demand businesses.
z/OS is the fl agship mainframe operating system based on the
Integrated system services
z/OS helps make critical data and processing functions accessible to end users regardless of their location in the heterogeneous on demand world. The z/OS base includes z/OS Communications Server, which enables world class TCP/IP and SNA networking support, including mainframe dependability, performance, and scalability; highly secure connectivity; support for multiple protocols; and effi cient use of networking assets.
