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.

An alternative method to balance load is to install RHN Proxy Servers below a RHN Satellite Server.
These Proxies connect to the Satellite for RPMs from Red Hat Network and custom packages created
locally. In essence, the Proxies act as clients of the Satellite.
This vertically tiered configuration requires that channels and RPMs be created only on the RHN
Satellite Server. In this manner, the Proxies inherit and then serve packages from a central location.
For details, refer to the
RHN Channel Management Guide
.
Similarly, you should make the Proxies' SSL certificates clients of the Satellite while also setting them
to serve the client systems. This process is described in the
RHN Client Configuration Guide
.
