Supervisor

Lab architecture: the existing management domain mgmt-a with its 4-host cluster and VNA cluster, the new one-host cluster cluster-mgmt-02a running the Supervisor, and the edge-less NSX path through the default transit gateway and VLAN 22 to the router.

One-Host Supervisor on VCF 9.1, Part 4: Enabling a Supervisor with One Control Plane VM

In Part 3 we gave NSX a way out without edges. Now we enable the Supervisor on the one-host cluster, with a single control plane VM instead of the usual three. Two things stalled it along the way, and I headed off a third before it could. I’ll go through all of them, then prove the result with a test pod. Before you begin vSphere HA and DRS on, HA admission control off (Part 2) The FTT=0 policy compatible with the vSAN datastore (Part 2) Five consecutive free IPs on the management network for the Supervisor (mine: 10.1.1.85 to 10.1.1.89) DNS servers that answer from the address they were queried on (more on that below) Then ask vCenter whether the cluster can take a Supervisor on VPC networking: ...

One-Host Supervisor on VCF 9.1, Part 1: Allowing Single-Host Clusters in SDDC Manager

I was working with a customer, and we were going through William Lam’s post on running VCF 9.1.1 on a single ESX host. They wanted a vSphere Supervisor so they could run VCF Private AI Services later, but only one of their hosts had GPUs in it. Buying two more GPU hosts just to meet a cluster minimum was not an option. So the question was simple: can we add a one-host cluster to the existing VCF domain and run a Supervisor on it? ...
