6.7

System Clock Synchronization Between the Client and Server
To establish a secure TLS connection to a Platform Services Controller or vCenter Server (the server), the
system where you are running the CLI installer (the client) must not have its system clock slower or faster
than the server's system clock by an acceptable limit (tolerance).
See Table 2‑6 for specific values for each deployment scenario.
Note The client clock values are applicable only for vCenter Server 6.7.
Table 2‑6. Client Clock Tolerance
Deployment Scenario Clock Tolerance Connection Notes
Linking one Platform Services Controller
with another Platform Services Controller
Clock tolerance for the client and the
external Platform Services Controller
must not exceed 10 minutes
The CLI installer must make a secure
connection to a
Platform Services Controller.
Linking a vCenter Server with an external
Platform Services Controller
Clock tolerance for the client and
external Platform Services Controller
must not exceed 10 minutes.
The CLI installer must make a secure
connection to a
Platform Services Controller.
Linking one vCenter Server with an
embedded Platform Services Controller
with another vCenter Server with an
embedded Platform Services Controller
When deploying the second
vCenter Server with embedded
Platform Services Controller, the clock
tolerance for the client and the first
vCenter Server with embedded
Platform Services Controller must not
exceed 10 minutes.
Installing a vCenter Server Appliance
using a container vCenter Server
vCenter Server with a *._on_vc.json
template.
The maximum clock tolerance between
the client and the container
vCenter Server is 8 hours 20 minutes.
Prerequisites for Deploying the vCenter Server Appliance
or Platform Services Controller Appliance
To ensure successful deployment of the vCenter Server Appliance or Platform Services Controller
appliance, you must preform some required tasks and pre-checks before running the installer.
General Prerequisites
n
Download and Mount the vCenter Server Appliance Installer.
n
For topologies with external Platform Services Controller instances, verify that you deploy the
different nodes with time synchronization between each other. All vCenter Server instances,
Platform Services Controller instances, and third-party load balancers in the vCenter Single Sign-On
domain must be time synchronized. See Synchronizing Clocks on the vSphere Network.
