Disk space allocation
On the FortiAnalyzer, the system reserves 5% to 25% of the disk space for system usage and unexpected quota overflow. The remaining 75% to 95% of the disk space is available for allocation to devices.
Reports are stored in the reserved space.
|
Total Available Disk Size |
Reserved Disk Quota |
|---|---|
|
Small Disk (up to 500GB) |
The system reserves either 20% or 50GB of disk space, whichever is smaller. |
|
Medium Disk (up to 1TB) |
The system reserves either 15% or 100GB of disk space, whichever is smaller. |
|
Large Disk (up to 5TB) |
The system reserves either 10% or 200GB of disk space, whichever is smaller. |
|
Very Large Disk (bigger than 5TB) |
The system reserves either 5% or 300GB of disk space, whichever is smaller. |
|
The RAID level you select determines the disk size and the reserved disk quota level. For example, a FortiAnalyzer 1000C with four 1TB disks configured in RAID 10 is considered a large disk, so 10%, or 200GB, of disk space is reserved. |
