6.5.1

If you install vCenter Server with an external Platform Services Controller, you first must deploy the
Platform Services Controller on one virtual machines or physical server and then deploy vCenter Server
on another virtual machine or physical server. While installing vCenter Server, you must select an existing
external Platform Services Controller. You cannot select an existing Platform Services Controller that is a
part of an embedded installation. For more information about the supported topologies, see vCenter
Server and Platform Services Controller Deployment Types.
About ESXi Evaluation and Licensed Modes
You can use evaluation mode to explore the entire set of features for ESXi hosts. The evaluation mode
provides the set of features equal to a vSphere Enterprise Plus license. Before the evaluation mode
expires, you must assign to your hosts a license that supports all the features in use.
For example, in evaluation mode, you can use vSphere vMotion technology, the vSphere HA feature, the
vSphere DRS feature, and other features. If you want to continue using these features, you must assign a
license that supports them.
The installable version of ESXi hosts is always installed in evaluation mode. ESXi Embedded is
preinstalled on an internal storage device by your hardware vendor. It might be in evaluation mode or
prelicensed.
The evaluation period is 60 days and begins when you turn on the ESXi host. At any time during the 60-
day evaluation period, you can convert from licensed mode to evaluation mode. The time available in the
evaluation period is decreased by the time already used.
For example, suppose that you use an ESXi host in evaluation mode for 20 days and then assign a
vSphere Standard Edition license key to the host. If you set the host back in evaluation mode, you can
explore the entire set of features for the host for the remaining evaluation period of 40 days.
For information about managing licensing for ESXi hosts, see the vCenter Server and Host Management
documentation.
