This section introduces the hardware requirements, network connectivity requirements, and more prerequisites for deploying a distributed system.

Reference Specification

As the number of network devices and concurrent users increase, the system requires a distributed environment, which requires more machines to provide resiliency and scale out flexibly based on your network scale. Both physical machines and virtual machines are supported.

Select an appropriate deployment way according to your node count:

▪Distributed deployment for 2001-5000 nodes

▪Distributed deployment for 5001-10000 nodes

▪Distributed deployment for 10001-50000 nodes

Notes:
1) Allocating at least half of the RAM amount for swap space on your Linux server is required to provide the necessary additional memory when the RAM space has been exhausted.

2) The required hard disk space must be exclusively reserved for NetworkBrain. For a network with more than 5,000 nodes, MongoDB must be installed on a machine equipped with Solid State Drive (SSD).
3) Each Front Server is recommended to manage 5,000 network nodes at most. For good performance of data processing and caching, it is recommended to install the Application Server on a machine equipped with Solid State Drive (SSD) when managing up to 5000 nodes.
