Explanation

In VMware Cloud Foundation (VCF), the lifecycle of the NSX Manager cluster is strictly managed by SDDC Manager. During the initial deployment of a Management Domain or the creation of a new Workload Domain (if using a separate NSX instance), the administrator selects a "Form Factor" (Small, Medium, Large, or Extra Large) based on the expected scale of the environment. As of current VCF versions (including 5.x), the Form Factor is a parameter defined during the deployment workflow that determines the resource reservations (CPU/RAM) and the disk partitioning of the appliance OVA. Unlike a standard virtual machine where you might simply adjust the vCPU and RAM settings in vCenter, the NSX Manager appliance is an opinionated system. Changing resources manually through vCenter (Option C) is not supported and can lead to stability issues or "Out of Sync" errors within SDDC Manager, as the database and internal services are tuned for the specific size selected at install.
