Open Systems Adapter Support Facility (OSA/SF)

OSA/SF is an element that supports S/390® Open System Adapter (OSA-Express and OSA-2) hardware features to deliver connectivity via directly-attached local area clients using:
  • Transmission Control Protocol/Internet Protocol (IP) network protocol
  • Systems Network Architecture Application Peer-to-Peer Networking
  • Internet Packet Exchange (IPX)

The OSA-2 features provide connection to Ethernet, Asynchronous Transfer Mode (ATM), Token Ring and Fiber Distributed Data Interface (FDDI) networks. OSA-Express provides connection to Ethernet networks supporting Fast Ethernet (FENET), 1000Base-T Ethernet and Gigabit, as well as Token Ring and ATM.

OSA/SF provides a user-friendly interface for monitoring and controlling the OSA features. Beginning in z/OS® V1R4, OSA/SF introduces support for a Java-based GUI interface, continues support for the OSA-2 features, and continues to provide the OS/2-based GUI.
