Data Networks in OpenStack Overview
|
|
===================================
|
|
|
|
Data networks are used to model the L2 Networks that nodes' data, pci-sriov
|
|
and pci-passthrough interfaces attach to.
|
|
|
|
.. note::
|
|
|
|
Data networks are required if you plan to deploy the openstack application
|
|
or provide |SRIOV| network interface access to container workloads.
|
|
|
|
A Layer 2 physical or virtual network or set of virtual networks is used to
|
|
provide the underlying network connectivity needed to support the application
|
|
project networks. Multiple data networks may be configured as required, and
|
|
realized over the same or different physical networks. Access to external
|
|
networks is typically granted to the **openstack-compute** labeled worker nodes
|
|
using the data network. The extent of this connectivity, including access to
|
|
the open internet, is application dependent.
|
|
|
|
Data networks are created at the |prod| level. Flat, |VLAN| and |VXLAN| type
|
|
data networks are supported by the |prod-os| virtual switch. For details on
|
|
creating data networks, assigning them to node interfaces, and displaying
|
|
data networks, see the following |prod| documentation:

|VXLAN| Data Networks are specific to |prod-os| application.
|
|
|
|
.. xreflink and are described in detail in :ref:`VXLAN Data Networks
|
|
<vxlan-data-networks>`.
|
|
|
|
Segmentation ID ranges for VLAN and VXLAN data networks are defined through
|
|
OpenStack Neutron commands, see :ref:`Adding Segmentation Ranges Using the CLI
|
|
<adding-segmentation-ranges-using-the-cli>`.
