This IBM Redbooks publication discusses techniques available for building a large farm of Linux servers running under zVM (a "penguin colony"). It has been developed for system administrators and I/T architects who are responsible for developing optimized solutions for large Linux systems installed on IBM eServer zSeries and S/390 machines.
The book is divided into three parts. We first discuss basic VM concepts and commands, and examine tools available on z/VM that can help you create and monitor a server farm.
We then cover networking features and options, and discuss network high availability issues and solutions. Finally, we demonstrate methods for optimizing virtual Linux server farms (including a novel approach to sharing Linux filesystems among members), and examine central LDAP management. The sample code we discuss is available online.
We also recommend when to use the z/VM IP stack as a router, when to use a virtual Linux IP router, and when to dedicate logical OSA ports to virtual Linux Servers. Linux cloning techniques are also covered.
