RAID level & disk statuses
If supported by your FortiWeb model, System > Config > RAID enables you to view the status of the redundant array of independent disks (RAID) that the FortiWeb appliance uses to store most of its data, including logs, reports, auto-learning data, and website backups for anti-defacement. You can also use this CLI command to view the statuses of each disk in the array, its total disk space capacity, and RAID level:
diagnose hardware raid list
RAID is supported on models that originally shipped with the firmware version FortiWeb 4.0 MR1 or later, such as FortiWeb 1000D/E, 3000C/CFsx/D/DFsx, and 4000D. On older appliances that have been upgraded to FortiWeb 4.0 MR1, you may be able to see this part of the web UI, but RAID is not activated, and the disk status is will always be Not Present

FortiWeb-VM does not support RAID from within the virtual appliance. However, depending on your hypervisor’s storage repository, you can configure the hypervisor to store its data on a SAN or external RAID. To manage your storage repository, see the documentation for your hypervisor. |
Currently, only RAID level 1 is supported, and cannot be changed. On FortiWeb 3000C/D and 4000C/D, the RAID array has a hardware controller. On FortiWeb 1000D/E, the array has a software controller. RAID level 1 is also known as “mirroring,” and writes all data twice—each drive is an exact copy of the other. This does not increase disk write speed via striping, nor detection and correction of errors via parity. However, it does improve availability by reducing the overall hardware failure rate of the RAID: the chance that both disks together will fail is much lower than the chance of failure of a single disk.
