Reference Specification

The two-server deployment requires one Windows server for applications and one Linux server for the database. Both physical machines and virtual machines are supported.

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) 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.

3) The required hard disk space must be exclusively reserved for NetworkBrain. For better performance, it is recommended to install the MongoDB on a machine equipped with Solid State Drive (SSD), or Hard Disk Drive (HDD) RAID-10.
