FortiGate Next Generation Firewall utilizes purpose-built security processors and threat intelligence security services from FortiGuard labs to deliver top-rated protection and high performance, including encrypted traffic.
Usually different part numbers in the same model of unit implies internal changes, including hard disk. This does not necessary means the HA can not be established properly between units with different P/N.
Cluster can be formed properly between two units with different mark/model of hard disk as long as the size of their mounted partition is the same.
To confirm if two units of the same model and generation but with different P/N can form a cluster properly, execute the following command and compare the hard disk details:
execute disk list
Unit 1: FortiGate 200D | Generation: 02.00 | P/N: P11534-05
UNIT1# execute disk list Disk Internal ref: 16 59.6GB type: SSD [ATA SanDisk SD6SA1M0] dev: /dev/sdb partition ref: 17 58.7GB, 34.4GB free mounted: Y label: 01652F63096029E8 dev: /dev/sdb1 start: 63
Unit 2: FortiGate 200D | Generation: 02.00 | P/N: P11534-08-02
UNIT2# execute disk list Disk Internal ref: 16 59.6GB type: SSD [ATA 64GB SATA Flash] dev: /dev/sdb partition ref: 17 58.7GB, 58.5GB free mounted: Y label: 53EBB2E22BBF7686 dev: /dev/sdb1
These two units have different hard disk model. Therefore, their P/N are different. However, they can establish an HA together properly because their partition size is the same.
The Fortinet Security Fabric brings together the concepts of convergence and consolidation to provide comprehensive cybersecurity protection for all users, devices, and applications and across all network edges.
