Single application server
The application server specifications in the following table are based on the number of managed devices. These specifications are for a live production environment.

Application server hardware specifications
Number of managed devices | Processor speed | Number of processors | Memory |
|---|---|---|---|
Up to 5,000 | 3 GHz | 2 | 8 GB |
5001–25,000 | 3 GHz | 8 | 24 GB |
The application server and database can run on the same host computer or different host computers or virtual machines (VMs).
Multiple application servers – required for management of more than 25,000 devices
An installation comprising of more than 25,000 devices might require multiple application servers and remote device agents.
See Installing for more information.
Note that when there are multiple application servers, the servers are not truly clustered, that is, they do not share data or content. It might be necessary to synchronize content by exporting the content from one server and importing it into the other(s).
Typically synchronized content includes rules and device adapters. See Importing-rules, Exporting-rules, Importing-device-adapters, and Exporting-device-adapters.
