When Linux on IBM System z Makes Sense (Cents) (July 2010)

In a July 15, 2010 presentation for Hillgang, the DC Vm and Linux Users' Group, Len Diegel offered a review of current trends and challenges across the IT industry, the impact of
Cloud computing, and a Total Cost of Ownership (TCO) analyses that compares running Linux on commodity servers (x86) with other solutions including VMware, z/VM, and public virtual solutions.

From the Hillgang abstract:

White Paper: Routing Between Hipersocket and Guest LANs Using Linux Router Appliances

This white paper is intended to provide a working discussion paper for system admins and network engineers charged with implementing a layer 3 router appliance between a z/VM guest LAN and a hardware hipersocket LAN in a zSeries environment.

Using the NJE/IP Bridge: A Sample Configuration and Example White Paper

This white paper describes a sample implementation of the NJE/IP Bridge, a product developed by Sine Nomine Associates and marketed by Barnard Software, Inc. The paper describes a sample network, and shows the configuration files and steps necessary to implement the sample network.

Configuring ESCON CTC Connections (Shimon Lebowitz, Israel Police National HQ)

This document describes a cookbook example of how to configure ESCON CTC connections between LPARs on a single zSeries system. It demonstrates how to plan and code the necessary IOCP statements to interconnect multiple LPARs, and provides additional references for further study.
