SharePoint Server Licensing – Failover Rights

I was working on a SharePoint installation where we would be using VMWare vCenter Site Recovery Manager to failover from the primary datacenter to a secondary datacenter for DR purposes. There would be identical infrastructure in the secondary datacenter, but it would be on standby. This got me thinking about licensing…I called Microsoft and they indicated that a SharePoint Server license by itself does NOT include failover rights and that you would need to purchase Software Assurance to be supported in this scenario. Good thing I called..
