Currently running vcenter 5.0 U1 at primary and recovery sites. These vcenter servers are currently in linked mode. In researching the upgrade to 5.1, I see a requirement that all vcenter servers in a linked mode group must be registered to the same SSO server. This seems like a requirement for a single point of failure if you want to use linked mode, if there is only one SSO server. I realize this applies to an environment without SRM as well. I bring this up in the SRM forum because I think it applies to most SRM environments.
My question is, how can I design for the recovery site to be independant of the primary site? Of course we want the recovery site to be available in a total loss of primary site scenario. In SRM 5.0 I believe linked mode is not required, but it is still recommended.
Maybe the answer is in SSO/vCenter design and I have not read enough about that yet. Just wondering if anyone has any thoughts...
