Virtualization Network Layer Design

Implementing the appropriate network design has a positive effect on an organization’s ability to meet its business goals. With a good design, the network configuration provides timely access to business data, while preventing unauthorized access.

VMware Integrated OpenStack supports two types of network deployment:

vSphere Distributed Switch

VMware NSX based networking

Both types of deployments are supported, but are not interchangeable. The main difference between the network deployment types is that the Neutron API integration with VMware NSX provides advanced networking functionality, while the vSphere Distributed Switch provides basic networking integration. Routing and distributed firewall and other advanced features that are fundamental to large-scale deployments are only available with VMware NSX.

See the VMware Integrated OpenStack documentation for more details about the feature difference between the two types of network deployments (http://pubs.vmware.com/integrated-openstack-2/topic/com.vmware.openstack.install.doc/GUID-3BEA41E9-569A-4F95-A6E4-8BE2D4E8BA76.html).

In this design document, we will focus on the VMware NSX design to integrate with VMware Integrated OpenStack.

For more details on the Network Virtualization section, please check the Software Defined Networking Technical Materials. The following section will give basic guidelines for VMware Integrated Openstack deployed with NSX-based networking.
