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
2.2.1. x86_64 Hardware Requirements
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
- Required: 4 GB of memory
- Recommended: 8 GB of memory
Storage
- 5 GB storage for base installation
- A minimum of 40 GB storage per software channel (including
Baseand 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/pgsqlin Red Hat Satellite 5.6 to/opt/rh/postgresql92/root/var/lib/pgsqlin 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
