¶ Configure RAID Disk Volume
Your system should be configured in RAID 0 by default. This section will help you either change your RAID configuration from RAID 0 to RAID 5, or vice-versa, or create a new RAID volume if any error has happened and the configuration is not correct.
IMPORTANT NOTE: any alteration to the RAID configuration will erase all the selected disks’ content. Be careful and backup all important data before following the next steps.
Pre-Requisite: this section assumes that “Intel® Rapid Storage Technology” software is installed on the server. If not, the software can be found in Intel®’s website.
- Execute “Intel® Rapid Storage Technology”;
- Check if all disks are show in the status tab, under “Storage System View”. All disks connected to the system will appear. The next picture shows the default 3 units of 3,5 TB disks;
-
If a RAID disk is already configured, we must first delete the current volume. If not, then you can skip to step 5;
a. Navigate to the “Manage” tab and click “Advanced”;
b. From there click “Delete Volume”;
c. Click “Yes” to confirm that all disk data will be deleted;
-
Your status should now appear like shown;
-
Open the “Create” tab. Select the “SATA” option and, depending on which RAID option you want, either select the option "Real-time data protection (RAID 0) or "Efficient data hosting and protection (RAID 5). Select next;

-
The configuration should be as follows:
a. Write-cache buffer flushing: enabled;
b. Cache mode: write through.
-
Click “Initialize”. A confirmation pop-up will appear. Click “Yes”;
-
The initialization will take a while, but the volume can already be used, and the next steps can be followed.
