Getting the Most Out of Your OSA Adapter with z/OS Communications Server


Presentation

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 LAN connectivity based on Queued Direct IO (QDIO). In the session we will discuss both configuration and operational aspects, such as maintenance of the OSA Address Table (OAT), ARP processing, use of Virtual IP Addresses (VIPA), interface availability, sharing capabilities, VLAN support, Virtual MACs, OSA Direct SNMP, and other management related functions. An introduction to HiperSockets Converged Interface (HSCI) will also be provided. HSCI allows users to logically converge their HS Interface with OSA providing significant usability advantages for z/OS users.   The focus will be on the software use of OSA, and will discuss hardware aspects only where such aspects are of importance to understanding how the hardware and software cooperate to deliver the desired function.
