Migrating to Linux on System z reading material

The picture I used last week came from the redbook : 'Practical Migration to Linux on System z' which was published a couple of weeks ago. This is a well-written publication on migrating/consolidating workloads to Linux on System z. It gives you a high-level tchnical overview on how to tackle such a migration project. Or as the authors state it : "(...) we attempt to present an end-to-end view of the technical challenges and methods necessary to complete a successful migration to Linux on System z". I particularly like the part on the migration analysis starting with z/vm and Linux on system z technical aspects (not too technical) and further focusing on Network analysis, Storage analysis, Application analysis, Database analysis, Backup analysis, Security analysis, Operational analysis and Disaster Recovery and Availability analysis. There are also some example cases.

So for some one who's (even only remotely) considering this kind of migration, this is definitely worth a read.

If you want to go a bit further down this path, you might also be interested in one or more of the following publications :
  • The manual Getting Started with Linux on System z (SC24-6194-00). I really want to quote the titles of most of the chapters of this manual as it gives you a wealth of technical information on the topic : About z/VM, Planning for Linux Virtual Servers, Changing the System Configuration, Configuring the Directory Maintenance Facility, Configuring TCP/IP, Restarting z/VM and checking the system, Creating your first Linux virtual Machine and installing linux, Cloning Linux Virtual servers . . .
  • Redbook z/VM and Linux Operations for z/OS System Programmers. I guess the abstract of this book really sums up accurately what it's about : "Although other books have been written about many of these topics, this book gives enough information about each topic to describe z/VM and Linux on IBM System z operations to somebody who is new to both environments. This book is intended for z/OS programmers and system programmers who are transitioning to the z/VM and Linux on System z environments and who want a translation guide for assistance." You can take this translating very literally. Very often z/VM concepts are compared to the z/OS ones in order to make clear how they are similar to or different from z/OS.
So, if you're about to start with Linux on System z, you have (to my opinion) some nice starting material gathered here, no matter whether or not you're already familiar with z/VM or Linux (on System z).
