Enhanced Linked Mode with External PSC and Mixed Mode using vCenter 6.5

Hey folks, we have discussed about the Enhanced Linked Mode and different architecture models that can be implemented with embedded and external PSC here. All those things still hold good for vSphere 6.5 as well, in this post, i want to try setup a Enhanced Linked Mode in Mixed mode – that would be fun! 

Below is the overview of the mixed mode model within a site.

In the post for vSphere 6, we saw how a vCenter server can be installed on a Windows machine, so we will just focus on deploying the VCSA with external platform which includes joining the PSC appliance to the existing PSC domain. Before continuing any further in this post, make sure that you have installed an external PSC on a Windows machine and also a vCenter Server part of that PSC as you can see in the snapshot above. To give you a better understanding, below are the review pages of both psc and vCenter Server 6.5.

Let’s now get going with the setting up of the PSC appliance and vCenter appliance. For this make sure the name resolutions and other network settings are in place. From any computer inn the same network, mount the VCSA iso and launch the installer in the below location since we are doing a graphical installation..

On the installer home page, click on the Install.

Setting up the appliance happens in two stages, in the first, the appliance VM is deployed on to the host and in the second stage, the appliance is  configured. Click Next to proceed.

Accept the EULA and click Next.

2016-11-16-18_14_08-win32

Since we are doing a external PSC installation, use the PSC radio button as we did in the Windows based installation.

2016-11-16-18_14_18-vcenter-server-appliance-installer

Provide the ESXi host details for the VM deployment.

2016-11-16-18_15_02-vcenter-server-appliance-installer

Setup a root password for the PSC appliance.

2016-11-16-18_15_39-vcenter-server-appliance-installer

Select the datastore for the PSC appliance, i used thin disk mode as this is done in my lab.

2016-11-16-18_15_56-vcenter-server-appliance-installer

Give a name and IP address for the PSC appliance, make sure the networking part is setup correctly and DNS entries are made.

2016-11-16-18_20_57-vcenter-vmware-workstation

Review the settings and click Finish.

2016-11-16-18_21_13-vcenter-vmware-workstation

Let the appliance get deployed.

To proceed with Stage 2; ie configuring the appliance, click on Continue.

2016-11-16-18_29_50-vcenter-vmware-workstation

Click Next on the below screen.

2016-11-16-18_30_21-vcenter-vmware-workstation

Setup the NTP for the appliance and Enabled for the SSH, as this is needed for setting up HA for the vCenter. Check out my What’s New in 6.5 for more about native HA.

2016-11-16-18_30_51-vcenter-vmware-workstation

On the next screen, make sure to select the radio button ‘Join an existing SSO domain’ for the Linked Mode and enter the details of the Windows based PSC name and the PSC domain.

2016-11-16-18_32_00-vcenter-vmware-workstation

In the next step, i am doing a Single site multiple PSC installation without load balancer so i used the radio button for ‘Join an existing site’ and click Next

Click OK on the warning but only after you understand it.

2016-11-16-18_34_43-vcenter-vmware-workstation

The PSC appliance has been deployed and joined to the existing PSC domain now. Click close.

2016-11-16-18_39_42-vcenter-vmware-workstation

The next thing to do would be to deploy and configure vCenter Server and this is also done in two stages. Select the vCenter at the below screen now.

2016-11-16-18_57_29-vcenter-vmware-workstation

Provide the ESXi details. Click Next.

2016-11-16-18_57_58-vcenter-vmware-workstation

Setup a password for the root account.

2016-11-16-18_59_17-vcenter-vmware-workstation

Based in the size of your deployment, select the values from the drop down.

2016-11-16-18_59_34-vcenter-vmware-workstation

Select the datastore for the VM deployment.

2016-11-16-19_05_53-vcenter-vmware-workstation

Provide the IP settings and click Next.
