Sielox offers software key licensing with its Pinnacle access control software solution. Capable of working in a virtual environment, Pinnacle’s set of core features—complete compatibility with Sielox 32-bit controllers, and seamless integration—provide a growing resource for advanced system design. The virtual environment controls where one instance of Pinnacle access control executes dynamically for fault tolerance. Either Pinnacle A or Pinnacle B or Pinnacle C will be running at a particular moment in time with one license. Fault tolerance provides failover capabilities and is provided by the virtual environment’s software, which hosts Pinnacle.
