This deployment guide assumes you are building an environment for a proof of concept. Refer to VMware best practice guides before building your production environment.
Installing VCenter Server Appliance (VCSA)¶
The VCSA is a preconfigured virtual appliance built on Project Photon OS that allows you to manage multiple ESXi hosts and perform configuration changes from a single pane of glass. Since the OS was developed by VMware and accelerated by NVIDIA vGPUs, it offers better performance and boot times than the previous Linux-based appliance. Furthermore, it uses an embedded vPostgres database, giving VMware complete control of the software stack in tandem with the performance of NVIDIA-certified Systems. This results in significant optimization for vSphere environments and quicker release of security patches and bug fixes, enabling IT admins to focus on organizational goals and strategic initiatives.
The VCSA scales up to 2500 hosts and 45,000 virtual machines. Features such as Update Manager are bundled into the VCSA, file-based backup and restore, and vCenter High Availability. The appliance also saves operating system license costs and is quicker and easier to deploy and patch.
A couple of releases ago, the VCSA reached feature parity with its Microsoft Windows counterpart and is now the preferred deployment method for vCenter Server.
As of vSphere 7.0, deploying a new vCenter Server or upgrading to vCenter Server 7.0 requires using the vCenter Server Appliance (VCSA). The new vCenter contains all Platform Controller services. Review the vCenter Server Components and Services guide for more details about the VCSA authentication services and other installed services with the new vCenter appliance.
VCSA must be deployed to an ESXi host running version 6.5 or above. In addition, all the hosts you intend to connect to VCSA should be running ESXi 6.5 or above. Hosts running v6.0 and earlier cannot be managed by the version 7 vCenter Server Appliance, and there is no direct upgrade path
You must check the compatibility of any third-party products and plugins that might be used for backups, anti-virus, monitoring, etc., as these may need upgrading for ESXi compatibility.
To check version compatibility with other VMware products Product Interoperability Matrix.
For more information, please refer to vSphere Software Requirements
When implementing a new ESXi environment, you must plan its topology following the VMware vCenter Server and Platform Services Controller Deployment Types.
Most deployments will include the vCenter Server and PSC in one appliance, following the embedded deployment model used in this guide.
All Platform Services Controller services are consolidated into vCenter Server, simplifying deployment and administration.
Hardware and Storage Requirements:¶
See the document Hardware Requirements for specifications. The corresponding size you select during installation will determine the number of CPUs and the amount of memory (disk can be thin provisioned).
See the document Storage Requirements for further details. Storage requirements for the smallest environments start at 250 GB and increase depending on your specific database.
The ESXi host on which you deploy the VCSA must not be in lockdown or Maintenance Mode.
All vSphere components must be configured to use an NTP server. The installation may fail, or the vCenter Server Appliance VPXD service may not start if the clocks are not synchronized.
FQDN resolution must be enabled when you deploy the vCenter Server.

vCenter Server Appliance (VCSA) Installation¶
Download the latest VMware vCenter Server Appliance ISO from VMware downloads.
Mount the ISO on your computer. The VCSA installer is compatible with Mac, Linux, and Windows.
Browse to the corresponding directory for your operating system, e.g.,
\vcsa-ui-installer\win32: right-click Installer and select Run as administrator.
As we are installing a new instance, click Install.
The installation is split into two stages, and we will begin with deploying the appliance. Click Next to start.
Read and accept the EULA, and then click Next to continue.
Select the ESXi host on which to install the VCSA as a guest. This must be a host that runs ESXi 6.5 or later. NVIDIA recommends that the vCenter server (Windows or appliance-based) run on a separate management cluster from the one designated for VDI workloads. Enter the IP address or fully qualified domain name (FQDN) of the chosen host, its root username, and password; then click Next.
If your desktop can reach the host, you should see a certificate warning as it connects. This warning is due to the use of a self-signed certificate. If you are using a signed certificate, you will not see this warning. Click Yes to continue.
The credentials are validated.
When prompted after a successful connection, provide a VM name for the vCenter Server 7, type the passwords in the Set Root password field, and enter the root password again, and click Next.
Select a deployment size appropriate to the number of hosts and virtual machines that vCenter Server will manage, then click Next.
Select the datastore where the VCSA will be deployed, select thin provisioning if required, and click Next.
The installer displays the Configure network settings. Before you configure these settings, choose an appropriate static IP address, and enter it into local DNS (e.g., on the Domain Controller). Once you can resolve the address, enter the IP address hostname on the network setting page, then scroll down and enter the remaining items. When all desired settings are complete, select Next.
Review the settings before starting the vCenter Server deployment and click Finish to start the installation.
The vCenter Server will start deploying on the specified target ESXi host. Installation progress can be viewed on the screen.
With the VCSA now deployed, move on to stage 2 by clicking Continue.
Select Next to proceed with Stage 2, setting up the vCenter Server.
Configure the NTP server by selecting the Time synchronization mode and Enabling the SSH access, then click Next.
Enter a unique SSO domain name, configure a password for the SSO administrator, click Next.
The default SSO domain name is vSphere.local. The SSO domain name should not be the same as your Active Directory Domain.
Select or deselect the customer experience improvement program box and click Next.
Review the details on the summary page and click Finish to finalize the setup.
The installer displays a warning that you cannot pause or stop the install once you start it. Click Ok to acknowledge the warning and start the install.
When the install process is complete, click Close to exit the installer and entire Stage 2 of the VCSA setup.
This section describes the post-install and configuration of the vCenter Server VCSA.
Adding Licenses to the vCenter Server¶
Use the following procedure to configure vCenter:
Connect to the vCenter post install using the IP or FQDN of the vCenter. Access vSphere by selecting Launch vSphere Client (HTML5).
The VMware Single Single-On page displays. Enter the username and password that you specified during installation, then click the Login button.
The VMware vSphere Web Client page displays.
You must apply for a new vCenter license key within 60 days. If you have purchased vCenter Server, log in to your licensing portal.
