Discover how RAID configurations improve data performance and redundancy on SSD-based Dedicated Servers → Learn more now
10 November 20263 min read1 Views0 helpful
Introduction
RAID (Redundant Array of Independent Disks) is a technology that combines multiple drives into a single logical drive to provide data redundancy and/or higher performance. There are different RAID levels, each offering different combinations of data distribution and fault tolerance.
Info
In the Hardware tab for your Dedicated Server in the ZapX panel, you can view your current RAID configuration (level, controller, volumes, drives) at any time. You can still change the RAID configuration only directly on the server using the hardware controller, as described in this guide—not with a button in the panel.
FAQ
Frequently asked questions
They currently have 2 SSD bays, allowing for RAID0 (combined volumes, no redundancy, slightly faster speeds) or RAID1 (mirrored volumes with data redundancy).
Your data remains available because it is mirrored across both SSDs. Only the failed SSD needs to be replaced, after which the server rebuilds the RAID.
No. The Hardware tab only displays your current RAID configuration. You can change it only on the server using the hardware controller.
It is automatically configured as RAID0.

Dedicated Server
Available RAID Types
Our Dedicated Servers currently have 2 SSD bays, allowing for two possible RAID configurations. The first is RAID0, which combines volumes into one large volume, and RAID1, which mirrors volumes to keep data redundant. We’ll explain both options in more detail below.
Info
RAID0 offers slightly faster read and write speeds because both drives are used in parallel.
RAID0
With this RAID configuration, all available volumes are combined into one large volume—for example, two 1 TB SSDs become a 2 TB partition that can be used in full.
There is no data redundancy, so a hardware failure can often result in data loss because data is written across different sectors.
If you store sensitive data on your system, you should avoid using RAID0 or at least make regular system backups.
Info
If your Dedicated Server has only 1 SSD, it is automatically configured as RAID0.
RAID1
This configuration is very different from RAID0 because it provides data redundancy. Everything you store on your server is duplicated.
The data is mirrored across both SSDs, so it remains available if 50% of the drives fail—in other words, your data is safe as long as 1 SSD is working.
If a hardware failure occurs, only the affected SSD needs to be replaced. Your server will then rebuild the RAID by mirroring the data again.
This configuration is highly recommended for sensitive data, but it does not replace a backup.
Info
Regular backups of all important data are essential!
The Configuration Wizard
When your server boots, you need to start the RAID configuration tool. To do this, press F8 at the appropriate point during startup.
Press F8 here to open the RAID configuration tool
This configuration overview will appear after a few seconds.
You’ll now see several menu options:
Create Logical Drive
Creates a new volume.
View Logical Drive
Displays the current RAID configuration.
RAID0
RAID1
Delete Logical Drive
You can delete the current RAID configuration here, for example, to create a new one.
Select Boot Volume
You can select a different storage device to boot from here, but you don’t need to do this with our setup.
Manage License Keys
No changes are needed here; the license is already preconfigured.
Cache Settings
You can adjust the cache option to slightly increase the SSD’s read and write speeds.
By default, the last data blocks are cached during every write operation, for example, as a safety measure in case of a power outage.
This can have a minimal impact on performance.
Create a New RAID
First, check that no volumes remain by opening Delete Logical Drive.
Press F8 to delete the existing RAID.
Press F3 to confirm the deletion.
Once the RAID has been deleted successfully, open Create Logical Drive.
Here you can see all your SSDs and select a RAID configuration.
Of course, not all RAID levels can be implemented with the current hardware configuration.
In our example, we’ll choose RAID0 or RAID1.
Info
You can switch between menus using TAB.
Once you’ve selected your RAID configuration, press Enter to confirm.
Info
You can close the configuration wizard by pressing ESC.
Select a Boot Volume
If you’ve changed your RAID configuration, you must select the boot volume.
This is easy to do under Select Boot Volume—select the logical drive you created, or your server will get stuck in a boot loop.
Select Boot Volume Direct Attached Storage Logical Drive 01 Press F8 to save as the boot volume
At the end, you can press F8 to restart your system immediately or press Enter to return to the main menu.
Important: You must always set the boot volume whenever you change your RAID configuration.
Conclusion
Congratulations, you’ve successfully configured RAID on your Dedicated Server. If you have any further questions or run into any issues, our support team is here to help every day! 🙂
