The following hardware configuration is required for the two types of RHN Satellite Server:
| Stand-Alone Database | Embedded Database |
|---|---|
| Dell PowerEdge 1750 or equivalent | Dell PowerEdge 2650 or equivalent |
| Two processors | Two 2.4 GHz processors |
| Required - 512 MB of memory | Required - 2 GB of memory |
| Recommended - 1 GB of memory | Strongly recommended - 4 GB of memory |
| 3 GB storage for base install of Red Hat Enterprise Linux AS | 3 GB storage for base install of Red Hat Enterprise Linux AS |
| 5 GB storage per channel, in the /var/satellite directory by default but configurable at install | 5 GB storage per channel, in the /var/satellite directory by default but configurable at install |
| Recommended - an external SAN for more reliable backups | Recommended - an external SAN for more reliable backups |
| 36 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 physical disks) for storing backups. This can be any directory specifiable at backup time. |
Table 2-1. Stand-Alone Database and Embedded Database Satellite Hardware Requirements
The following hardware configuration is required for the Stand-Alone Database:
Dell PowerEdge 2650 or equivalent
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 in which client systems connect to the Satellite is directly related to load on the Apache HTTP Server and the database. If you do reduce the default interval of four hours (or 240 minutes), as set in the /etc/sysconfig/rhn/rhnsd configuration file of the client systems, you will increase the load on those components significantly.
Additional hardware requirements include:
The Stand-Alone Database must not run on the same server as the RHN Satellite Server.
The package repository may be any large storage device easily and securely accessed by the other components. The space requirements depend on the number of packages that will be stored. Default Red Hat channels contain approximately 3 GB of packages each, and that size grows with each synchronization; customers must also account for the space requirements of packages in their own private channels. Whatever storage solution the customer chooses, its mount point may be defined during the installation process.
