2.2. Hardware Requirements

This section specifies a Red Hat Satellite server's hardware considerations and requirements for installation.

Depending on the desired use case, a Red Hat Satellite environment might require multiple machines:

Red Hat Satellite with Embedded Database - 1 machine
Red Hat Satellite with Embedded Database and Enhanced Reporting - 2 machines
Red Hat Satellite with Managed/External Database - 2 machines
Red Hat Satellite with Managed/External Database and Enhanced Reporting - 3 machines

The following list shows the required and recommended hardware configurations on the x86_64 platform for a Red Hat Satellite server:

CPU

Required: Intel dual-core processor, 2.4GHz, 512K cache or equivalent
Recommended: Intel quad-core processor, 2.4GHz dual processor, 512K cache or equivalent

Memory

Storage

5 GB storage for base installation
A minimum of 40 GB storage per software channel (including Base and child channels), in /var/satellite/, configurable at install
A minimum of 10 GB storage for cache files stored within /var/cache/rhn. See Section 2.4.5, “Caching” for more information.
Strongly Recommended: A SCSI drive connected to a level 5 RAID

Database

See Section 2.3.1, “Database Sizing” for standard database requirements.
Embedded Database: A minimum of 12 GB storage for the database repository in the /opt/rh/postgresql92/root/var/lib/pgsql/ partition on the Satellite host. This partition must be local storage only.
Important
Due to an updated version of the PostgreSQL Embedded Database, the database location has changed from /var/lib/pgsql in Red Hat Satellite 5.6 to /opt/rh/postgresql92/root/var/lib/pgsql in Red Hat Satellite 5.7. Make sure to allocate enough hard disk space to this location.
Managed Database: A minimum of 12 GB storage for the database repository in the /opt/rh/postgresql92/root/var/lib/pgsql/ partition on the Managed Database host. This partition must be local storage only. The instructions for installing this database are a part of the Managed Database installation scenario .
External Database: See Section 4.3.1, “External Database Requirements”.

Backup

A separate partition (or better, a separate set of physical disks) for storing backups, which can be any directory specifiable at backup time
An external SAN for more reliable backups
