O b t aining t h e Req u ired Package Set s
Each version of Red Hat Enterprise Linux requires a certain package set to support Satellite Proxy.
Adding more packages can cause errors during installation. Therefore, Red Hat recommends
obtaining the desired package set in the following ways:
For kickstart installations, specify the following package group: @ Base
For installing Red Hat Enterprise Linux from CD or ISO image, select the following package group:

2.2. Hardware Requirement s
Use the following guidelines to determine if your hardware is suitable for a Satellite Proxy
installation:
A Pentium IV Processor or equivalent.
At least 2 GB of memory. 4 GB of memory recommended.
At least 5 GB of storage for a base installation of Red Hat Enterprise Linux.
6 GB of storage per architecture per release.
The caching mechanism used by Satellite Proxy is the Squid HTTP proxy, which saves significant
bandwidth for the clients. Cached packages are stored in the /var/spo o l /sq ui d directory. The
more disk space that the cache has available, the less likely it is to remove RPM files before they
have expired. Providing less than the recommended storage reduces the performance
enhancements offered by using the Proxy server.
Satellite Proxy 5.7 features the ability to precache entire channels. Using this feature requires
significant disk space; Red Hat recommends at least 20 GB per base channel. Refer to the hardware
guidelines in the Red Hat Satellite Installation Guide in you intend to use this feature. Proxy precaching
is discussed in Section 4.2, “Configuring Proxy Precaching”.
If the Satellite Proxy is configured to distribute custom, or local packages, make sure that the /var
mount point on the system storing local packages has sufficient disk space to hold all of the custom
packages, which are stored in /var/spo o l /rhn-pro xy. The required disk space for local
packages depends on the number of custom packages served.
The load on the Apache Web server is directly related to the frequency with which client systems
connect to the Satellite Proxy. If the default interval of four hours (or 240 minutes) is reduced, the
load on this component increases significantly. This value is set in the
/etc/sysco nfi g /rhn/rhnsd configuration file of each client system.
Note
The installation procedure optimizes the caching abilities for the available resources. Provide
more memory and disk space prior to installation to increase active caching within Red Hat
Satellite Proxy.
