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) The required hard disk space must be exclusively reserved for NetBrain. For better performance, MongoDB Server is recommended to be installed on a machine equipped with Solid State Drive (SSD), or Hard Disk Drive (HDD) RAID-10.
2) Each Front Server is recommended to manage 5,000 network nodes at most.
3) The sentinel node of Cache Server Cluster can be installed on any one of Worker Servers.
