FortiAnalyzer can receive logs and Windows host events directly from endpoints connected to EMS, and you can use FortiAnalyzer to analyze the logs and run reports.
The number of disks you have may be a factor in deciding the number of groups you use in building a RAID array.

For example, if you have 15 disks, two groups of 7 disks would leave 1 disk unused.  In order to make use of all disks, it would be better to select 5 disks.

This article describes how to select the RAID group when formatting FortiAnalyzer for RAID-50 or RAID-60.

The number of RAID groups used in a RAID array can only be selected when formatting from the FortiAnalyzer CLI console.

The current RAID status will be accessible through below command:
"diagnose system raid status"
The current raid setting on this box is Raid-50 with 3 groups 


The command  "execute format disk *" will show the valid RAID levels for the FortiAnalyzer appliance.


To identify the number of groups that could be implemented with the current disk count & RAID level, use the format command followed by an asterix:

execute format disk 50 *
execute format disk 60 *

The available options on a FortiAnalyzer 3500F with 24 disks are as follows:
