Dell EMC PowerEdge MX7000 - Networking Requirements; VMware Cloud Foundation Networking

Networking requirements
This section covers the networking requirements from both the Cloud Foundation software perspective and from a networking hardware
connectivity perspective. This section also briey describes the conguration options for conguring networks on a Dell EMC PowerEdge
MX7000 chassis. The actual networking conguration procedures are described in the later sections.
Topics:
• VMware Cloud Foundation networking
• Network conguration options
• Network connectivity
• VLAN and subnets for networking conguration
VMware Cloud Foundation networking
A successful VMware Cloud Foundation deployment relies heavily on networks that are constructed and allocated to Cloud Foundation.
The networks are used by Cloud Builder during the installation and conguration process and then used by Cloud Foundation to carry out
various activities. The dierent networks are allocated to specic purposes and have dierent requirements.
VMware Cloud Foundation requires six networks and at least one connection to a customer network (for external access to your Cloud
Foundation stack). In the following example, a private IP address range is used for all connectivity within the management stack. There is
also an IP network that connects back to an external network.
Each of these networks is propagated to the Cloud Foundation stack using tagged VLANs. Using tagged VLANs enables mapping of port
groups to VLANs allowing access to resources as needed. All these networks are routable to and from each other. The routing task is
executed at some layer above the access level switched fabric that is deployed here.
The networks required to deploy Cloud Foundation are listed in the following table:
Table 9. Networks required to deploy Cloud Foundation
Network Description
Management Dedicated to communication between all the deployed resources and services. When the SDDC Manager
Utility needs to communicate to any other service or resource, it uses the management network.
vSAN Used to communicate and synchronize vSAN storage trac across multiple hosts to ensure data integrity
and resiliency.
vMotion Used to quickly redistribute virtual machine state and or storage between hosts.
VXLAN VMware NSX uses VXLAN to extend NSX networking constructs from host to host. This network is
sometimes referred to as the VTEP Network.
Uplink 1 and Uplink 2 VMware Cloud Foundation uses these networks for northbound and southbound trac when an NSX
Edge Gateway is deployed.
