Hi All,

As we know that vSphere 6.0 comes with a new technology called “Embedded Platform Services Controller” which consists some specific services controlling the vCenter in Single/Multi vCenter Environment.

These below Services governed by Platform Service Controller .

          • vCenter Single Sign-On

          • vSphere License Service

          • VMware Certificate Authority

Lets see how can we configure them and How many types are there.

          • vCenter Server with Embedded PSC
          • vCenter Server with an External Platform Services Controller
          • Mixed Operating Systems Environment


vCenter Server with an Embedded Platform Services Controller

vCenter Server and the Platform Services Controller are deployed on a single virtual machine or physical server.

Advantages:

  1. The connection between vCenter Server and the Platform Services Controller is not over the network, and vCenter Server is not prone to outages because of connectivity and name resolution issues between vCenter Server and the Platform Services Controller.
  2. If you install vCenter Server on Windows virtual machines or physical servers, you will need fewer Windows licenses.
  3. You will have to manage fewer virtual machines or physical servers.
  4. You do not need a load balancer to distribute the load across Platform Services Controller.

Disadvantages:

  1. There is a Platform Services Controller for each product which might be more than required. This consumes more resources.
  2. The model is suitable for small-scale environments.

vCenter Server with an External Platform Services Controller

vCenter Server and the Platform Services Controller are deployed on separate virtual machine or physical server. The Platform Services Controller can be shared across several vCenter Server instances. You can install a Platform Services Controller and then install several vCenter Server instances and register them with the Platform Services Controller.

Advantages:

  1. Less resources consumed by the combined services in the Platform Services Controllers enables a reduced footprint and reduced maintenance.
  2. Your environment can consist of more vCenter Server instances. vSphere Installation and Setup 14 VMware, Inc.

Disadvantages:

  1. The connection between vCenter Server and Platform Services Controller is over the network and is prone to connectivity and name resolution issues.
  2. If you install vCenter Server on Windows virtual machines or physical servers, you need more Microsoft Windows licenses.
  3. You must manage more virtual machines or physical servers.

Mixed Operating Systems Environment

A vCenter Server instance installed on Windows can be registered with either a Platform Services Controller installed on Windows or a Platform Services Controller appliance. A vCenter Server Appliance, can be registered with either a Platform Services Controller installed on Windows or a Platform Services Controller appliance. Both vCenter Server and the vCenter Server Appliance can be registered with the same Platform Services Controller within a domain.

Having many Platform Services Controllers that replicate their infrastructure data, allows you to ensure high availability of your system.

If an external Platform Services Controller with which your vCenter Server instance or vCenter Server Appliance was initially registered, stops responding, you can repoint your vCenter Server or vCenter Server Appliance to another external Platform Services Controller in the domain.

This is all the models which can be followed if you are using the vCenter PSC Controller in your deployment.
