Sysplex and Network Topology Considerations
Project and Program: Enterprise Data Center
, Communications Server
, SHARE in Orlando 2011
In this session we will look at how to provide optimized network access to the images and between the images of a z/OS Sysplex. Various newer networking technologies will be reviewed and explained, such as Hipersockets performance enhancements for streaming workloads, multiple virtual LAN support by OSA, the use of virtual MAC addresses, QDIO acceleration, using WLM service level information to choose QDIO outbound priority queue, etc. The session will also review various Sysplex access network topology examples and discuss aspects of each. In particular the session will discuss the impacts of using stateful firewalls in the Sysplex access network and what to watch out for in such scenarios.
