Server Complexes

The Server Complexes task is a subtask of the z/VM Center. By creating and using server complexes, you can control the configuration of virtual Linux guests in a z/VM, in an automatic fashion.

This topic provides a brief introduction to the main objects you work with in the Server Complexes task and the functions you can perform using these objects.

Linux guest systems

A Linux guest system is an IBM Director managed object. This object represents a Linux system running as a guest operating system in a z/VM virtual server. From the point of view of IBM Director, a Linux guest system is simply a Linux system running an IBM Director agent.

Server complexes

A server complex is a virtual complex that is used to configure the properties of Linux guest systems in a z/VM. This includes both the z/VM side and the Linux side configuration. Within the context of a managed z/VM, you can create as many server complexes as required.

Tier

A tier is a sub-section within a server complex. You can divide a server complex into multiple tiers, each with their own set of properties. You can use tiers to group Linux guest systems according to their functionality.

Server complex properties

Server complexes have four configuration domains: VMRM, minidisks, scripts, and network. You can set properties for some or all of these domains and apply these properties to Linux guest systems within the server complex. You can also set the properties of a single tier within a server complex.

Provisioning resources

Provisioning resources are the virtual server templates, operating system templates, and disk pools that can be used in the cloning process. These resources are maintained in the VSD task. Cloning is the process of creating a Linux guest system and configuring it according to server complex properties.
