Installing vCenter Server 6.0 best practices (KB2107948)


This article provides information about installing VMware vCenter Server 6.0 Best practices.

Note: This article assumes that you have read the vSphere 6.0 Installation and Setup documentation.
The documentation contains definitive information. If there is a discrepancy between the documentation and this article, assume that the documentation is correct. Ensure that you have read the known issues in the VMware vSphere 6.0 Release Notes.


Deployment models and Platform Services Controllers

With vSphere 6.0, we have introduced deployment models and Platform Services Controllers. There are two deployment models:

    ■ Embedded Deployment Model:
    – vCenter Server with an embedded Platform Services Controller
    ■ External Deployment Model:
    – External Platform Services Controller.
    vCenter Server with external Platform Services controller.

For more information about when to use the external or embedded deployment models, see vCenter Server Deployment Models.

Warning: Although the installation can complete successfully, some resulting topologies may not be recommended by VMware. For a list of recommended topologies and mitigation steps, see List of recommended topologies for vSphere 6.0.x (2108548).

Warning: If you decide on an external model, the installation must be done sequentially starting with the platform services controllers, not concurrently.

If you have used vSphere 5.x you may be familiar with some services that were previously deployed independently of vCenter Server. For more information about how the vSphere 5.x services map to the new vSphere 6.0 servers, see Migration of Distributed vCenter Server for Windows Services During Upgrade to vCenter Server 6.0 in our documentation.

vCenter Server for Windows Requirements

To install vCenter Server on a Windows virtual machine or physical server, your system must meet specific hardware and software requirements. For more information, see also following related Prerequisites.

vCenter Server for Windows Hardware Requirements
vCenter Server for Windows Storage Requirements
Required free space for system logging
vCenter Server for Windows Software Requirements
Supported host operating systems for VMware vCenter Server installation (including vCenter Update Manager and vRealize Orchestrator) (2091273)
Verify that the FQDN is resolvable
Synchronizing Clocks on the vSphere network
vCenter Server for Windows Database Requirements
VMware Product Interoperability Matrix

vCenter Server Appliance Requirements

The appliance upgrade process has changed significantly from the previous release. There is now an ISO file containing the appliance that can be downloaded. The ISO contains an installer that will deploy the appliance to a host running ESXi 5.1.x or later. The tool runs in a browser on a Microsoft Windows Platform. The tool requires the client integration plugin to function and therefore must meet it’s requirements. For more information about installing the Client Integration Plug-in Software on your windows platform, see Install Client Integration Plug-in. For information about the appliance upgrade tool, see Upgrade the vCenter Server Appliance.

Prior to installing vSphere 6.0, please ensure you have these requirements:

vCenter Server Appliance Hardware Requirements
vCenter Server Appliance Storage Requirements
Verify that the FQDN is resolvable
Synchronizing Clocks on the vSphere network
vCenter Server Appliance Software Requirements
vCenter Server Appliance Database Requirements
Software Included in the vCenter Server Appliance

vSphere Web Client Software Requirements

Make sure that your browser supports the vSphere Web Client.
The vSphere Web Client 6.0 requires Adobe Flash Player 16 or later. The latest Adobe Flash Player version for Linux systems is 11.2. Therefore, the vSphere Web Client cannot run on Linux platforms.
VMware has tested and supports these guest operating systems and browser versions for the vSphere Web Client. For best performance, use Google Chrome.

vSphere Web Client Software Requirements

If you plan to install the Client Integration Plug-in separately from the vSphere Web Client so that you can connect to an ESXi host and deploy or upgrade the vCenter Server Appliance, make sure that your browser supports the Client Integration Plug-in.
To use the Client Integration Plug-in, verify that you have one of the supported Web browsers.

vSphere Client Requirements

You can install the vSphere Client to manage single ESXi host. The Windows system on which you install the vSphere Client must meet specific hardware and software requirements.

Supported host operating systems for vSphere Client (Windows) installation (2100436)
TCP and UDP Ports for the vSphere Client

Frequently Asked Questions

Q: Are Oracle databases supported as an external database for vCenter Server Appliance?
A: Oracle 11g and 12c are supported as external databases in vCenter Server Appliance 6.0

Q: Will Oracle databases continue to be supported beyond vSphere 6.0 for vCenter Server Appliance?
A: Oracle 11g and 12c as an external database for vCenter Server Appliance is deprecated in the 6.0 release. VMware will provide general support as per lifecycle support policy.

Q: What is the plan to support Microsoft SQL databases with vCenter Server Appliance 6.0?
A: There is no plan to support Mircosoft SQL database as an external database. Embedded vPostgres database supports scale limits of 1,000 hosts and 10,000 virtual machines.

Q: Can I deploy vCenter Server Appliance using OVFTOOL?
A: Starting with vSphere 6.0, the user interface based installer is the only supported method to install and upgrade vCenter Server Appliance.

Q: Why can’t I deploy vCenter appliance on vCenter Server cluster?
A: This feature is planned for a future release.

Q: What is considered too large for an embedded deployment model?
A: An embedded deployment model can only include a single instance of vCenter Server. If your requirements exceed the limits of a single instance of vCenter Server, you should consider using an external model.

Q: What is considered too small for an external deployment model?
A: If you only require a single instance of vCenter Server and you do not expect the environment to grow, you should consider an embedded model.
