You have really good hardware configuration. See this http://docs.hortonworks.com/HDPDocuments/Ambari-2.2.1.0/bk_ambari_reference_guide/content/ch_tuning_...

Make sure that you use dedicated database for services like Ambari server, hive, oozie , Ranger

As suggested by the document as referred to by @Neeraj Sabharwal, it's important to take care of Ambari Metric System memory requirement as well, in case it is going to be installed in the same system as Ambari Server. In which case I would recommend to plan for at least 16-32Gb only for AMS. More than 16 Gb if the cluster is going to run Hbase.
