NSX-T Backed Workload Domains with Multiple Physical NICs

Last week, I shared an example of how to create a new workload domain with VMware Cloud Foundation (VCF) using hosts with more than two physical NICs. In that example, I used NSX-V in the creation of the workload domain. Today, I’d like to provide an example of how you would do this for a NSX-T backed workload domain.

As support for multiple physical NICs (>2) is a newly supported feature with the VCF 3.9.1 release, doing this requires the use of the VCF APIs.

Multiple Physical NICs in VCF

With the VCF 3.9.1 release, support for hosts with multiple physical NICs has been added. This allows you to dedicate specific traffic across specific physical NICs to conform to your best practices. Let’s take a quick look at how this is configured…

By default, VCF will use the first two physical NICs (vmnic0 and vmnic1) on a host for all traffic. When working with a host with multiple physical NICs, you will need to define what the physical NICs are connected to (VDS or N-VDS). The VDS or N-VDS will need to exist, of course.

Manually Uploading VCF Bundles

Although VMware Cloud Foundation (VCF) will automatically download the software bundles once connected to the Internet, there are times that you may wish to manually inject the software bundles into the SDDC Manager using the API.

After the initial deployment of VCF is completed, additional bundles may be required to enable optional functionality. For example, the bundles for Horizon, PKS, and vRealize Automation are optional and would be downloaded and then installed as needed. Because these bundles can be quite large and VCF downloads them in a serial fashion, it can be faster at times to inject the bundles into VCF manually through the API.
