How many vCenter servers can be registered against a single Sso server?
VMware HA and VMware DRS clusters can support up to 32 hosts and 3,000 virtual machines. So, if you need to manage a large virtual environment, you can register multiple vCenter Server against a single SSO server. Generally, an ELM consists of a single SSO Domain, so you can have a maximum of 10 vCenter Servers per SSO Domain.
How to view multiple vCenter environments in a single vSphere client view?
In the olden days, multiple vCenter environments and geographically dispersed sites could easily be seen in a single vSphere Client view by configuring them in Linked Mode. Linked Mode is great for having fewer panes of management. There are a lot of cons with this route as well:

The host can only be managed by one vCenter at a time.
Is vCenter Server necessary?
Who Needs To Use vCenter? Technically speaking, you don't need vCenter Server to run VMs on top of ESXi hosts. However, for production environments, vCS is mandatory. This is because vCS unlocks all the great features that production environments need, including vSphere HA, vMotion, and DRS.

Can vCenter 6.7 Manage ESXi 7 hosts?
VMware vCenter 7.0 can manage ESXi 7.0, ESXi 6.7 and ESXi 6.5, but vCenter 6.7 cannot manage ESXi 7.0 hosts. Thus, you have to upgrade vCenter first and only then proceed to the ESXi upgrade if you want to upgrade vSphere 6.7 to 7.0.

I cannot found the maximum number of cluster that a vCenter can manage, only the maximum number of hosts per cluster, that is 32... but absolutely you can have more than one cluster without problem.
What is vCenter Server High Availability?
vCenter High Availability (vCenter HA) protects vCenter Server against host and hardware failures. The active-passive architecture of the solution can also help you reduce downtime significantly when you patch vCenter Server.
What's the best practice for multiple vCenter servers? : vmware
I just recently became more involved with virtualized environments, and I've setup a few sites for my company now in geo-diverse locations. All of my sites are on the same MPLS network.
Solved: Is it possible to have Multiple vCenter Servers lo ... - VMware
Dear. So I have setup an extended PSC to handle SSO for two vcsa6 servers in enhanced-linked mode (ELM) and I noticed although both vcsa servers are in the same site under the same sso domain I have to create different Networking structures since both vcenters appear to handle different DataCenters.
Multiple Vcenter and best practice - VMware
Dear all, I need an advice about my Vcenter 6.0 architecture. We have twenty sites accross the world, each one have his proper Vcenter Server. Each Vcenter Server is unique on each site we have no cluster, no HA and no DRS, I know it's not the best case. I would like to create a new "super" vcent...

Does vSphere 5.1 have SSO?
With the vSphere 5.1 addition of Single Sign-On (SSO), it dramatically complicates the design itself. This topic won't mean much for SMBs because you should be pretty well off with a single vCenter and SSO instance. This is primarily going to be focused on large enterprise designs.
Can you register multiple vCenter servers against a single SSO server?
When using the webclient, any vCenter server that is registered to that central SSO server will be viewable and navigable. See a screenshot by William Lam ibelow. Hmm.. that brings up an interesting design consideration. If Linked Mode was only being considered to have fewer panes of management, why do I even need to configure it any longer? Good question. IMO, Linked Mode is dead. You can accomplish the same premise of having fewer vCenter panes of management by registering every vCenter with SSO. The only stipulation is that this is only compatible with the vSphere Web Client. I know many of us today still use the C# client based on it's speedy responsiveness and more granular messaging, but this is a reason to atleast have both open at the same time.
Can VPLEX be used in a DR?
If we wanted to take this design further, we could add VPLEX in the mix. VPLEX could abstract a pod in the main datacenter, as well the the DR pod. These two pods could create a "management cluster" that hosts critical infrastructure virtual machines and the entire loss of one site would enable an easy vSphere HA restart of the VMs on another site. This takes us back down to a single pane of management as well.
Current VMware vCenter Configuration
As I mentioned previously I have two VM ware vCenter 6.7 U3 servers called VCLOUDPG-VC-A and VCLOUDPG-VC-B (VCLOUDPG stands for vCloud PlayGround, which is an area I do quite a bit of testing in). Each vCenter server has its own embedded platform services controller and has an SSO domain of vsphere.local.

Now that the domain re-join has completed successfully, we can check the replication partner via cli from VCLOUDPG-VC-B by entering into the shell, changing directory to /usr/lib/vmware-vmdir/bin and typing the following:
How many topologies are supported for multiple vCenters?
There now 8 supported topologies for multiple vCenters and “Enhanced” Link Mode – and 3 depreciated one as well.

Does Microsoft give SSO rights to vCenter?
Even if you give a Microsoft AD user/group complete rights to vCenter from a top-level container – this doesn’t necessarily give those AD user/groups rights to manage SSO itself. This handled by different subset of permissions and rights. Typically, SysAdmins like to do this delegation to prevent situations such as loosing, forgetting or getting locked out of VMware SSO, which then prevents further administration. VMware SSO has its own systems of password policies and lockouts.
Does vSphere 5.1 have SSO?
