1.8 Connection scenario between EMS, HMC, and Frame
The network interconnect between the different system components (EMS server, HMC,
Frame) requires the managing, running, maintaining, configuring, and monitoring of the
cluster. The management rack for a POWER 775 Cluster houses the different components,
such as the EMS servers (IBM POWER 750), HMCs, network switches, I/O drawers for the
EMS data disks, keyboard, and mouse. The different networks that are used in such an
environment are the management network and the service network (as shown in Figure 1-49
on page 61). The customer network is connected to some components, but for the actual
cluster, only the management and service networks are essential. For more information about
the server and management networks, see 1.7.4, "Server and management networks" on
page 55.
