vCAC has a feature that can be enabled to provide support for Static IP address assignments of provisioned workloads. This Static IP Address feature allows you to create “Network Profiles” that you assign to your networks from which it assigns IP addresses to machines that are provisioned on to the network. vCAC handles IP address allocation in the following way:
- When a machine request is submitted it get placed on the appropriate reservation that is assigned to the group that can support the request.
- Once placed on the reservation it get’s assigned to a network. If the network has a “Network Profile” assigned to it the machine will receive the next available IP Address form the “Network Profile. If not no address will be assigned.
- As pat of the machine provisioning process you can execute “VMware Customization Specs” that perform the sysprep operation on the provisioned machine. When an IP address is assigned from a “Network Profile” vCAC instructs vCenter to override the customization spec with the IP information assigned to the machine. (When using VMware cloning either customization specifications” or the “vCAC Guest Agent” is required for static IP address assignments.)
