Fedora mirror servers use Tiering, whereby a select few fast mirrors get read access to the master rsync servers, and all the other mirrors pull from those mirrors.

It turns out, 9 of our 10 Tier 0 or Tier 1 mirrors are available over Internet2. And, over half of our total mirrors are reachable over Internet2. So, let's make use of that whereever we can.

For our purposes, define:

  • master: The Red Hat servers download*
  • Tier 0: The fast mirrors which pull from Red Hat's Internet2-connected master
  • Tier 1: The fast mirrors which pull from the Tier 0 servers (or one of the other masters).
  • Tier 2: The mirrors that pull from the Tier 1 servers.

Properties of Tier 0 and 1 mirrors:

  • Limit the number of Tier 1 mirrors to 10, to ensure adequate bandwidth for these. Adjust number up or down depending on capability of the masters.
  • Must carry everything under fedora-enchilada and fedora-epel. This allows Tier 2 mirrors to exclude what they wish, but get everything if they so wish. This means at least 1TB of disk space for the Fedora portion of this server.
  • Must have a 1 Gigabit connection to the Internet, or faster.
  • Must have an active, available, responsive mirror administrator during the days content is staged.
  • Must have at least 2 Internet2-connected Tier 1 mirrors.
  • Must have at least 1 Tier 1 mirror on each continent for which we have Tier 2 mirrors
  • Must serve private rsync

Tier 0 Mirrors

Tier 0 mirrors can pull from Red Hat directly over the Internet2 connection.
