For very large networks, a more distributed method may be needed, such as having multiple RHN Satellite Servers in a horizontally tiered configuration and balancing the load of client requests.
It is possible to synchronize content between RHN Satellites using the rhn-satellite-exporter and satellite-sync -m commands. This feature is discussed in detail in Section 6.1.1 rhn-satellite-exporter.
Additional maintenance is the biggest disadvantage of this horizontal structure.
