5.1 Before the installation
Before the actual installation, we describe the topology, the installation flow, and the few
pre-installation steps that you have to consider.
5.1.1 The topology
In this topology, we use two xSeries Linux machines as our management servers to manage
the workload that runs across multiple platforms. In this topology:
򐂰 The first xSeries Linux machine is used to configure the Virtualization Engine console and
the IBM Director that the Virtualization Engine console uses to obtain its information for
managing the environment, otherwise known as its management source.
򐂰 The second xSeries Linux machine is used for Tivoli Provisioning Manager for
provisioning servers into and out of our IT environment, based on our business needs.
We used two Blades of an HS20-8832 server, each Blade had four processors. The two Linux
for xSeries images were SuSE Linux version 2.4.21-278-smp.
Figure 5-1 shows the management topology that we used with two management servers.
