vSphere 5.1 SSO with Site DR with SRM 5.1

hello

I have a doubt in an environment of mounting main site to site DR

I have 2 sites:

matrix:

2 esxi hosts 5.

1 vcenter

1 AD

DR Site;

2 esxi hosts 5.

1 vcenter

1 AD

I have no license vcenter heartbeat to replicate configurations of vcenter

and my doubts regarding the installation of SSO which type of configuration should I install on the main site: HA or Multisite and what settings should I do in the DR site to replicate these settings on 2 sites

Thank you
