Logical Design for vCenter Server for the Management Domain

For the management domain of each VMware Cloud Foundation instance, you deploy a vCenter Server appliance that manages the ESXi hosts that are running the management components of the SDDC and supports integration with other solutions for monitoring and management of the virtual infrastructure.

Figure 1. Logical Design of vCenter Server

Table 1. vCenter Server Logical Components

Single VMware Cloud Foundation Instance with a Single Availability Zone	Single Instance with Multiple Availability Zones	Multiple VMware Cloud Foundation Instances
One vCenter Server instance that is allocated to the management domain and the management components of the SDDC, such as the NSX Manager cluster, SDDC Manager, and other solutions.	One vCenter Server instance that is allocated to the management domain and the management components of the SDDC, such as the NSX Manager cluster, SDDC Manager, and other solutions. A should-run VM-Host affinity rule in vSphere DRS specifies that the vCenter Server appliance should run in the primary availability zone unless an outage in this zone occurs.	In each VMware Cloud Foundation instance, one vCenter Server instance that is allocated to the management domain and the management components for the VMware Cloud Foundation instance, such as the NSX Manager cluster, SDDC Manager, and other solutions. One vCenter Single Sign-On domain for all vCenter Server instances across VMware Cloud Foundation instances. When using multiple availability zones, a should-run VM-Host affinity rule in vSphere DRS specifies that the vCenter Server appliance should run in the primary availability zone unless an outage in this zone occurs.
