The other option is to deploy the vCenter Server and the PSC as separate virtual machines. In this architecture, the PSC can be shared across several vCenter Server instances. You can install a PSC and then install several vCenter Server instances and register them with the PSC. Then, you can install another PSC and configure it to replicate data with the first PSC. Finally, you can install additional vCenter Server instances and register them with the second PSC.
