FortiAnalyzer-BigData hardware environment

FortiAnalyzer-BigData 4500F and FortiAnalyzer-BigData 4500G units are available. Each unit is a 4U chassis with two 10G network switch modules and 14 blades in the enclosure.

• The first blade is responsible for log collection and services for FortiView, Log View, Reports, and more.
• The remaining 13 blades, also known as hosts, are responsible for the web GUI, log storage, data processing, and analytics.

Unit	CPU per blade	RAM per blade	Storage per blade
4500F	two 2.1GHz Intel Xeon 8 Core 16 Thread (8C16T) CPUs	128GB	196GB
4500G	two 2.3GHz Intel Xeon 16 Core 32 Thread (16C32T) CPUs	two 7.68TB NVMe SSD	two 7.68TB NVMe SSD

The two network switch modules on the back of the chassis have different functions.

• Switch Module #1 connects to the FortiAnalyzer-BigData cluster’s internal network.

  Use this switch only when you need to scale the existing Security Event Manager by adding new appliances.

• Switch Module #2 is the External Switch Module used to expose the FortiAnalyzer-BigData to external networks.

The Chassis Management Module (CMM) sits between the two switch modules in the middle of the back panel.

For more information about the CMM, see the appripriate FortiAnalyzer-BigData Getting Started Guide for your appliance on the Fortinet Document Library.
