1. NFA Hardware & Software Requirments

NFA is a web-based network traffic analysis, monitoring and alerting tool. The product enables engineers to optimize their networks and applications performance, control bandwidth utilization, do the proper network capacity planning, perform detailed BGP peering analysis, improve security and minimize network incidents response time.

NFA is intended for use in a production environment. The product should be installed on a dedicated server that meets the following hardware and software requirements:

Hardware Requirements: #

• x86_64 architecture
• Minimum 4x core CPU (8x core CPU recommended), SSE4.2 support
• Minimum 32GB of RAM (64GB RAM recommended; 128GB RAM – optimal)
• Minimum 250GB SSD storage (500GB SSD storage recommended) allocated to the /var partition

Software Requirements: #

• Ubuntu 20.04, Ubuntu 22.04 or Ubuntu 24.04 LTS

Please note that NFA can also be installed on a server running RHEL 8 / RHEL 9. The minimum system requirements assume default configuration. Significantly increasing the flow collection rate might cause additional load on a server, thus requiring extra memory or a larger CPU.

Hardware resources depend on the amount of flows/s exported to NFA. For each additional 1,000 flows/sec, 1 GB of RAM and 0.2 of vCPU are required. An additional 2 GB of RAM and 4 vCPU are required when the BGP add-on is used. Values are directly proportional: RAM and vCPU numbers per 1,000 flows/sec.

For instance: 40,000 flows/sec will require 40 GB of RAM and 8 vCPU, plus 2 GB of RAM and 4 vCPU in case a BGP add-on is used.
