    • 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 2.4.4, “Caching” for more information.

Database

Important

Red Hat Satellite 5.6 now stores Embedded Database files within /var/lib/pgsql/ instead of /rhnsat/. Take in consideration this change of disk location for Embedded Database files for previous Satellite deployments. Ensure to allocate sufficient disk space for the /var/lib/pgsql/ directory.

Other

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