vCenter Server 6.0 Deployment Models and Recommended Topologies

vSphere 6.0 has finally arrived! Many engineers and architects are wondering what are the new recommended topologies for the Platform Services Controller (PSC) and vCenter Server. I have compiled a list of recommended topologies in vSphere 6.0. For starters, you can think of the PSC as Single Sign-On + more. It provides the same functionality as SSO would have, but has additional services and functionality built in. All of these topologies can utilize either a Windows deployment, or an appliance for the PSC and  or vCenter Server.

Multiple PSCs and one or more vCenter Servers.

Obviously there are many more combinations that you can use, but these are a very high level of whats recommended. Again it’s important to note that you the PSCs or vCenter Servers can be either Windows based or appliance based, whatever suits your environment best!

    What doesVMware mean with a maximum number of VMware products/solutions. We have 10 Virtual Centers, 10 SRM servers and also 2 servers for VRealize Operations manager. Is this 22 solutions or 3 solutions?
    And what happens when you go over the limit?

      Hi David,

      Are you referring to the limit in the configuration maximums document below?

      https://www.vmware.com/pdf/vsphere6/r60/vsphere-60-configuration-maximums.pdf

      “Maximum number of VMware Solutions connected to a single PSC: 4”

      As I understand this is a soft limit based off testing and since SRM and VRO creates a solution user I would count them both. In your case you have 22 solutions which would require at least 6 external PSCs.

      Thanks,
      Sean

    Hi Sean, I’m a little bit confused. First I receive a mail from you were you say that you recommend al least 3 external PSCs and here you say 6.

      Hi David, sorry for the confusion. I had to edit my post once I realized SRM and vCO were actually considered solutions.

      Hi David,

      I have just received new information. SRM does not count as a solution for the PSC. Site Recovery Manager (SRM), vRealize Orchestrator (vRO), vRealize Automation (vRA), and vRealize Operations (vROp) only utilize part of the libraries of the PSC.

    Hi Sean,

    The maximum number of vmware solution is 10. I am planning to have 7 VCs and 6 PSCs, 3 VCs in Site A with 2 PSCs, 2 VCs each in site B & C with 2 PSCs. Will it count as 2 Solutions (VC / PSC) or 13.

    Hi Sean,

    I read the statement again and found only vCenter is defined as a fully integrated solution and counts against these maximums. Which means 7 solutions in one single domain in my case.
