As seen previously, starting from vSphere 6.0, vCenter is composed of the PSC and vCenter Server components. The PSC is a multi-master model component that provides licensing, authentication, and certificate services. If the PSC fails, these services stop working and consequently, the entire infrastructure will no longer work.

During the design of your virtual infrastructure, you should consider the option of installing and configuring two PSCs at the site to ensure availability. To ensure service availability, you may need to connect vCenter Server to another external PSC or to point the vCSA with an embedded PSC to an external PSC.

Let’s see how to configure vCenter Server to point to different PSCs.
