8.2 Multiple managed system configuration
To save space and to centralize multiple system management control points, you can
configure up to 48 managed systems on a single HMC. In Figure 8-3 and Figure 8-4, we show
the current HMC management scenario of one HMC managing two servers and then one
HMC managing three servers.
As you increase the number of managed servers, you will definitely need to introduce
hubs/switches into your private network. You should plan for redundancy and maintenance in
these hubs and switches, as the network is crucial to system management.
Figure 8-3 shows one HMC managing two iSeries servers.
