Controller-Less Network Virtualization

As networks grow more flexible and agile, enterprises are turning to

network virtualization in the data center to increase cost

effectiveness and gain a competitive edge. Network Director

completely automates the creation and management of overlay

fabrics on top of Layer 3 IP fabrics (underlay networks) utilizing an

Ethernet VPN (EVPN) control plane and VXLAN-based overlay

topology. The process follows a simple workflow that includes:

• Defining and mapping tenants to VRFs and VXLANs

• Defining tenant segments and mapping those segments to

VLANs and VXLAN associations

• Multihoming server settings

• Associating gateways for tenants

• Providing full visibility into each tenant and overlay network, as

well as correlated views of overlay and underlay networks

Multipoint Navigation and Views

Network Director improves operational efficiency by allowing users

to manage the network from different views, groupings, and

perspectives. It includes a customizable dashboard that provides a

visual indication of overall network usage and network consumers,

including VMs, hosts, top virtual networks, flow analysis, utilization,

latency, top talkers, and alarms—all presented as part of a color-

coded heat map representing devices and ports. Each device is

color coded to convey the level of port utilization and latency;

“cooler” colors indicate lower port utilization and latency while

“hotter” colors indicate higher port utilization and latency (see

Figure 6).

In addition, Network Director Topology view shows all discovered

devices in the network on a map where the devices are located

across sites, buildings, floors, closets, and racks, along with their

physical connections to other devices in the network. Topology

view also shows the physical and logical connectivity between

various discovered interconnected devices. Topology view allows

users to zoom in or out of a site, see how a device is connected to

its immediate neighbors, including VMware hosts connected to the

switch, or view alarm details, bandwidth of links, and real-time link

data and state of the devices. Network Director also enables

devices to be rearranged across buildings on the map.

Specifications

Network View and Device Selection

• View devices grouped by logical relationships, locations, device

type, custom group view, data center view, or topology view

• Select logical, location, device-type, custom group, virtual, or

topology view groupings to perform tasks on multiple devices

simultaneously

• Search for devices in the network

• Define filters to selectively view specific logical, location,

device-type, custom group, virtual, or topology groupings
