2.2. Hardware Requirements

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 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 /var/opt/rh/rh-postgresql95/lib/pgsql/data 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 to /var/opt/rh/rh-postgresql95/lib/pgsql/data in Red Hat Satellite 5.8. 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 /var/opt/rh/rh-postgresql95/lib/pgsql/data 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 (See Section 3.2.2, “Mounting the Installation Media”).
• External Database: See Section 3.3.1, “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

CPU

• Required: 1 IFL, either in LPAR configuration or shared through z/VM
• Recommended: 2 or more IFLs on z9 or earlier, 1 or more IFL on z10

Memory

• Required: 4 GB of memory
• Recommended: 8 GB of memory

Storage

• Required:
  • 1 GB swap on ECKD DASD
  • 1xMod3 ECKD DASD or ≥ 2 GB FCP SCSI LUN 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.
• Recommended:
  • 512 MB swap on VDISK + 1 GB swap on ECKD DASD
  • 1xMod9 ECKD DASD or ≥ 2 GB multipathed FCP SCSI LUN 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.

Other

• z/VM 5.3 or later for kickstart and provisioning of guests.
• VSWITCH or HiperSocket LAN for high speed connections to guests
