Two Different Sites vCenter and Single SSO in only one site

[RanjnaAggarwal]

Is that possible that Two Different Sites vCenter's can share the Single SSO that is in only one site?

Yes, you can have a single SSO and multiple vCenter Servers pointing to it.

"Deploying vCenter Single Sign-On in Basic mode means that a standalone version of vCenter Single Sign-On is installed on a system. Multiple vCenter Server, Inventory Service, and vSphere Web Client instances can point to this standalone version of vCenter Single Sign-On."
