vCenter Server Virtual Appliance (vCSA) is still very rare in a production environment. This hasn't changed much with the enhancements in vSphere 5.5 where the embedded database scalability has been lifted. VMware vCenter Server Appliance 6.0 does now support up to 1000 ESXi Hosts and 10.000 Virtual Machines with the embedded Postgres database. I hope i can deploy more vCenter Linux Appliances in the future.
