Hardware Requirements

A CORD POD is built using the following hardware components.

Generic Hardware Guidelines

  • Compute Machines: CORD canin principle be deployed on any x86 machine, either physical or virtual. For development, demos or lab trials you may want to use only one machine (even your laptop could be fine, as long as it has enough resources). For more realistic deployments, we suggest using at least three machines (preferably all the same). The characteristics of these machines depends several factors. At the very minimum, each machine should have a 4 cores CPU, 32GB of RAM, and 100G of disk capacity. More sophisticated use-cases, for example M-CORD, require more resources (see below).

  • Network Cards: For whatever server use, it should have at the very minimum a 1G network interface for management.

  • Fabric Switches: Fabric switches should be compatible with the ONOS Trellis application that controls them. We strongly recommend using one of the tested models suggested. 10G switches are usually preferred for initial functional tests and lab deployments since they are less expensive. Moreover, 10G ports can be usually downgraded to 1G speed, and it's possible to connect them using copper SFPs. The number of switches largely depends by your needs. For basic scenarios one may be enough. For more complete fabric tests, we recommend at least four switches. Developers sometimes emulate the fabric in software (e.g., using Mininet), but this applies only to specific use-cases.

  • Access Devices: At the moment, both R-CORD and M-CORD work with very specific access devices, as described below. We strongly recommend using these tested devices.

  • Optics and Cabling: Some hardware may be picky about the optics. Both optics and cable models tested by the community are provided below.

  • Other: In addition to the above, you will need a development/management machine and an L2 management swich to connect things together. Usually a laptop is enough for the former, and a legacy L2 switch is enough for the latter.

Following is a list of hardware that people from the ONF community have tested over time in lab trials.

BOM Examples

The following are some BOM examples you might wish to adopt.

Basic Lab Tests

Sufficient to modify/develop basic software components, and deploy locally in a lab.

  • 1x x86 server (maybe with a 10G interface if need to support VNFs)
  • 1x fabric switch (10G)
  • 1 DAC cables (if need to support VNFs)
  • Ethernet copper cables as needed
  • Access equipment as needed
  • 1x or more developers' workstations (i.e. laptop) to develop and deploy
  • 1x L2 legacy management switch

Complex Lab Tests

For a more realistic deployment, you can build a POD with the following elements:

  • 3x x86 server (maybe 10G/25G/40G/100G interfaces if need to support VNFs)
  • 4x fabric switches (10G/25G/40G/100G)
  • 7 DAC cables + 3 to connect servers (if need to support VNFs)
  • Ethernet copper cables as needed
  • Access equipment as needed
  • 1 or more developers' workstations (i.e. laptop) to develop and deploy
  • Alternatively a management/development server
  • 1x L2 legacy management switch
