Getting the Most Out of OSA and HiperSockets with z/OS Communications Server

Project and Program: Enterprise Data Center, Communications Server

Tags: Proceedings, SHARE Phoenix 2019, 2019

z Systems OSA-Express ports are used for both SNA and IP LAN connectivity to z Systems operating systems. In this session, we will focus on how z/OS Communications Server uses OSA for IPv4/IPv6 LAN connectivity based on Queued Direct IO (QDIO) architecture. The session will cover the operational aspects of OSA as well as configuration options for optimizing both inbound and outbound network traffic. The focus will be on the software use of OSA, and the speaker will discuss hardware aspects only where such aspects are of importance to understanding how the hardware and software cooperate to deliver the desired function.-Jerry Stevens-IBM Corporation
