The Platform Test team for System z has published two new white papers that should help readers to get a smooth start with Live Guest Relocation in z/VM 6.2.
- Early Experiences with z/VM 6.2 and Live Guest Relocation: moving from CSE to SSI: This paper describes the installation differences to a classical z/VM installation as experienced by the test team. It's not replacing the product documentation but rather augmenting it.
- z/VM Single System Image Cluster Live Guest Relocation with HiperSockets: Exploitation via Dynamic Routing: Live Guest Relocation and HiperSockets look like a contradiction at the first glance. If you move a z/VM guest off the CEC - what do you do with this network interface? This paper offers a clever approach to this problem, while keeping the solution as flexible as possible.
- z/VM Migration: Migrating the User Directory and RACF Environment: This document describes an automated migration to a new SSI environment using REXX scripts.
- z/VM 6.2 Live Guest Relocation with Linux Middleware: This paper looks at a Java application and the impact and performance for moving it in various scenarios. It also gives recommendations on how to best set up z/VM for Live Guest Relocation
- z/VM 6.2 Live Guest Relocation with Linux Middleware - Various Workloads: This is the follow on paper to the one above with additional workloads and more in depth analysis. Besides looking deeper at Java it also uses a OLTP database workload and a file system workload for comparison and analysis.
- The z/VM performance update (starting at page 16) at SHARE contains quite some performance results for LGR.
- An Introduction to z/VM Single System Image (SSI) and Live Guest Relocation (LGR): This really is an introduction to the new z/VM functionality
- Using z/VM v 6.2 Single System Image (SSI) and Live Guest Relocation (LGR): This book is a little bit more advanced with concrete examples of moving e.g. an Websphere and a DB2 guest under load.
