2.2. Hardware Requirements
RHN Satellite supports several hardware architectures. The following table illustrates the architecture support for RHN Satellite on both Red Hat Enterprise Linux 4 and Red Hat Enterprise Linux 5.
| RHEL Version | x86 | x86_64 | s390 | s390x |
|---|---|---|---|---|
| RHEL 4 | yes | yes | yes | yes |
| RHEL 5 | yes | yes | no | yes |
2.2.1. x86 and x86_64 Hardware Requirements
The following table shows the required and recommended hardware configurations on the x86 and x86_64 platform for the two types of RHN Satellite:
| Stand-Alone Database | Embedded Database |
|---|---|
| Required - Intel Core processor, 2.4GHz, 512K cache or equivalent | Required - Intel Core processor, 2.4GHz, 512K cache or equivalent |
| Recommended - Intel multi-core processor, 2.4GHz dual processor, 512K cache or equivalent | Recommended - Intel multi-core processor, 2.4GHz dual processor, 512K cache or equivalent |
| Required - 2 GB of memory | Required - 2 GB of memory |
| Recommended - 8 GB of memory | Strongly recommended - 8 GB of memory |
| 5 GB storage for base install of Red Hat Enterprise Linux | 5 GB storage for base install of Red Hat Enterprise Linux |
At least 30 GB storage per software channel (including Base and child channels), in /var/satellite/, configurable at install | At least 30 GB storage per software channel (including Base and child channels), in /var/satellite/, configurable at install |
| Recommended - an external SAN for more reliable backups | 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 physical disks) for storing backups. This can be any directory specifiable at backup time. |
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 240 minutes) as set in the
/etc/sysconfig/rhn/rhnsd configuration file of the client systems significantly increases the load on those components.
