Setup The Network Hardware

To set up the network hardware

  1. Connect the lowest-numbered Gigabit Ethernet adapters (the ones which will appear as eth0 in the Linux device list) of each server to the Gigabit switch, which will serve as the grid Backbone.

    A multi-port switch with the following can be shared between several grids:

  2. Verify that the Spanning Tree Protocol (STP) is disabled on the backbone switch.
  3. Connect the second Ethernet adapter of each server to the network that has access to the Internet.

    Strict observance of the order in which network adapters are connected is not required, but consistent wiring will help when configuring IP addresses.

  4. Only configure the NIC connected to the backbone network to PXE boot. See step 2 in Installing on an Existing CentOS System for instructions.

Note: Do not physically connect the backbone switch to the one used for public Internet access, the two networks must remain separate.
