Deploy vCenter with external PSC

Deploying a vCenter with an external PSC gives the capacity to use correctly some functions like enhanced linked-mode. A colleague ask me why using this instead of a full appliance with all the roles installed. Well honestly, for some customers during my works, I often use one appliance during migration from older vCenter to the last one. But for a fresh install, I recommand to use the model with external PSC.

The installer is in the same directory as a previous post about PSC installation.

Once the installer is loaded, then you can select Install.

The first steps are really closed of the PSC deployment wizard because … it is the same installer gui until …


Until ….


Until this step where you have to make a “life choice” : vCenter Server (Requires External Platform Services Controller)


You need to define the ESXi host where you want to deploy the solution.


Click Yes for the certificate validation.


Define the name of the “VM” inside ESXi. If you remember, this decision is important because all the files, folder, .vmx .vmdk etc … are based on this.

You define the root password which allows you to connect to the appliance through an ssh session etc


I am using a deployment size (Tiny vCenter Server). It is for my home lab so it is not really important.


I select the correct storage already configured and I enable thin disk because I won’t be able to make a lot of things without it.


In this part, I configured the appliance it self. I selected the Network (only VM PortGroup on Standard vSwitch is usable). I define the system name, IP address and network settings.

After that, I have a review then I click finish …


This first part is now finished. You can take some time to have a coffee, cup of tea, water if it’s hot or anything you want to drink that is allowed during your work. But I can recommand :

Hot Tea Break

Cold Tea Break

Coffea Break

After some times, you can then define you external PSC that you configured before, with the sso domain name and all the things around. Then you click Next.

On the last step, you click on Finish or just stop and do it another day.

Well, If you are here, you made the choice (the good one ?), to continue. Click OK

Instead of watch a movie, you can watch the progress of the status bar … and learning a little bit of the main services which are started during the installation.

Here you are, you are ready to go to the next level of vSphere … configuration and management.


Like the PSC post, you can use the link to configure NTP and TimeZone

Time Menu


Time Configuration …


And for AD integration, it is a little bit different.

First you have to open an ssh session on the vCenter and launch the shell …

And then you need to pass a command : /opt/likewise/bin/domainjoin-cli join “your-ad-domain” user and give the right password.


And then reboot the appliance. On your AD infrastructure, well it is magic because the vCenter appears.



Now let’s move to the configuration …
