Skype for Business Server 2015 Enterprise Edition supports large enterprise pools which provides high availability, scalability and resiliency. Enterprise edition supports scalable front end pools which can be extended up to 12 front end servers per pool while you need minimum 3 front end servers to setup enterprise edition front end pool. Mediation Server can be collocated with front end pools while rest of the server roles can be deployed either as a standalone server or as a pool.
