    Hi, is it still a 1-1 relationship between vCenter Server and SSO instance. If i point vCenter Server A to SSO siteasso will SSO sitebsso take over the authentication process for vCenter Server A if SSO siteasso becomes unavailable?

    What if you wanted 2 vCenters within the same site? would you select the middle SSO deployment mode option? Other than “add to an existing site”, what else does it do? You mentioned ” islands of SSO instances”, can you elaborate on that?

    Also, I’ve never been able to find what VMware constitutes as a vCenter “Site”. Is it similar to an AD site or just a way to separate location?
