Recommended - an external SAN for more
reliable backups
12 GB storage for the database repository, in the
/rhnsat partition (local storage only)
Strongly recommended - a SCSI drive connected
to a level 5 RAID
Separate partition (or better, a separate set of
phys ical disks ) for storing backups. This can be
any directory specifiable at backup time.
Note
Satellite requires a lot of disk space. Allocate space accordingly and ensure there is plenty of
room for the installation to grow. The recommendation given might not be suitable for all
environments.
Beyond the space needed for Red Hat Enterprise Linux installation and /var/satellite/, you also
need space for cache files generated when using Satellite, which get regenerated, as needed, if deleted.
These cache files are stored within /var/cache/rhn, and the storage needs of this directory will vary
greatly depending on the following factors:
how many channels you sync or import from RHN or Channel dumps
how many custom packages and channels you have
Whether or not you are using Inter-Satellite Sync
As a guide, provide at least 10 GB of space for /var/cache/rhn/ on a Satellite s erver. For very large
Satellite deployments with numerous channels, packages, and using Inter Satellite Sync, your usage
could grow to as much as 100 GB of space for cache files in /var/cache/rhn.
The following hardware configuration is required for the Stand-Alone Database:
Two processors
2 GB of memory
See Section 2.3, “Database Requirements” for instructions on estimating the tablespace of the database
and setting its environment variables.
Keep in mind, the frequency with which client systems connect to the Satellite is directly related to load
on the Apache Web server and the database. Reducing the default interval of four hours (or 24 0
minutes) as set in the /etc/sysconfig/rhn/rhnsd configuration file of the client systems
significantly increases the load on those components .

2.2.3. Additional Requirements
Additional hardware requirements include:
The Stand-Alone Database must not run on the same server as the RHN Satellite.
The package repository may be any large storage device easily and s ecurely accessed by the other
components. T he space requirements depend on the number of packages that will be stored. Default
