FAQs about RAID Array

FAQs about RAID array

For a RAID array, at least two hard drives or (NVMe M.2) SSDs are required. To achieve optimal performance, the hard drives or SSDs should be of the same size and come from the same model series. The BIOS screenshots in this manual are for reference only and may differ from the exact settings for your motherboard.
⚠️Note⚠️ Please note that the BIOS setup menus shown in this FAQ may differ from the specific settings of your motherboard. Depending on your motherboard model and the BIOS version installed, the BIOS setup menu options actually displayed may look different.

    • Asrock B860

    • Turn on your PC and press the F2 or Delete key to enter the BIOS Setup. Navigate to Storage Configuration \ VMD Configuration, ensure that the Enable VMD controller and Enable VMD Global Mapping are set to enabled. Press F10 to save the settings and exit the BIOS.

      Configuring the RAID Array:
      After a restart, enter the BIOS Setup again. Open the Advanced \ Intel(R) Rapid Storage Technology submenu.
      Under the Intel(R) Rapid Storage Technology menu, access the Create RAID Volume dialog with Create RAID Volume. Enter a name for the volume consisting of 1-16 letters (without special characters) after the Name entry and confirm with Enter.

      Select the desired RAID level and confirm with Enter.

      Asrock_3.png

      Choose the hard drives to be included in the RAID array and confirm with Enter.

      Asrock_4.png

      Select a stripe size for the RAID array or use the default setting and confirm with Enter.

      Asrock_5.png

      Select Create Volume and confirm with Enter to start creating the RAID array.

      Once the BIOS settings have been made, you can proceed with the operating system installation using the RAID drivers.
      Since Windows does not include RAID drivers, it is necessary to integrate the Intel® RST VMD Controller drivers during installation. Download the Intel SATA Preinstall driver from the Asrock site, unzip the file and copy the contents of the ZIP archive to a USB stick.

      1. Boot from a Windows installation media, follow the instructions until you reach the dialog: Select an installation type:
        Windows-setup_1.png
        Select Custom

      2. You will be asked for the installation drive, click on Load driver.

      4. Then follow the further installation steps.
  • RAID array for Gigabyte mainboards

    • Gigabyte intel

    • Turn on your PC and press the Delete key to enter the BIOS Setup. Navigate to Settings \ IO Ports \ SATA And RST Configuration, ensure that SATA Controller(s) is set to enabled. For RAID configuration, open Settings \ IO Ports \ VMD setup menu and set Enable VMD controller to Enabled and Enable VMD Global Mapping to Disabled. Then, depending on whether SATA / M.2 storage devices are used, enable the corresponding entries in Map this Root Port under the VMD item.

      Configure the RAID array

      The next steps can be skipped if no SATA ports are used for the RAID.

      After a restart, call up the BIOS setup again. Open the Settings \ IO Ports \ Intel(R) Rapid Storage Technology submenu.

      Under the Intel Rapid Storage Technology menu, access the Create RAID Volume dialog with Create RAID Volume. Enter a name for the volume consisting of 1-16 letters (without special characters) after the Name entry and confirm with Enter. Then select the RAID level. Depending on the number of installed storage devices, the levels RAID 0, RAID 1, RAID 10, and RAID 5 are offered. Use the arrow keys to select Select Disks.

      Gigabyte_3.png

      Under Select Disks, choose the hard drives or SSDs to be included in the RAID array. Press the Spacebar to select a drive (selected ones are marked with an X). Then set the block size, with values ranging from 4 KB to 128 KB possible. After selecting the stripe block size, set the capacity of the volume.

      Gigabyte_4.png

      After setting the size, go to Create Volume and press Enter.

      Gigabyte_5.png

      The Intel Rapid Storage Technology dialog will then be displayed again. Under RAID Volumes, an overview of the RAID volume is now shown. Press Enter to view detailed information about the RAID.

      Installation of RAID Drivers and Windows
      After configuring the BIOS settings, you can proceed with the operating system installation using the RAID drivers.

      Since Windows does not include RAID drivers, integrating the Intel® RST VMD Controller drivers during installation is necessary. Download the Intel SATA Preinstall driver from the Gigabyte site, unzip the file and copy the contents of the ZIP archive to a USB stick.

      Installing the RAID Driver and Operating System

      With the correct BIOS settings, you are ready to install the operating system.

      Installing Windows

      As some operating systems already include RAID driver, you do not need to install separate RAID driver during the Windows installation process. After the operating system is installed, we recommend that you install all required drivers from the motherboard driver disc using "Xpress Install" or from the GIGABYTE APP Center to ensure system performance and compatibility. If the operating system to be installed requires that you provide additional RAID driver during the OS installation process, please refer to the steps below:

      Step 1:

      Method 1: Copy the Hw10 folder under the \BootDrv folder in the driver disc to your USB thumb drive.

      Method 2: Go to GIGABYTE's website, browse to the motherboardmodel's web page, download the AMD RAID Preinstall Driver file on the Support\Download\SATA RAID/AHCI page, unzip the file and copy the files to your USB thumb drive.

      Step 2:

      Boot from the Windows setup disc and perform standard OS installation steps. When the screen requesting you to load the driver appears, select Browse.

      Step 3:

      Insert the USB thumb drive and then browse to the location of the driver. When a screen as shown in Figure 1 appears, select AMD-RAID Bottom Device first and click Next to load the driver. Then select AMD-RAID Controller and click Next to load the driver. Finally, continue the OS installation.

      Rebuilding an Array

       

      Rebuilding is the process of restoring data to a hard drive from other drives in the array. Rebuilding applies only to fault-tolerant arrays such as RAID 1 and RAID 10 arrays. To replace the old drive, make sure to use a new drive of equal or greater capacity. The procedures below assume a new drive is added to replace a failed drive to rebuild a RAID 1 array.

      While in the operating system, make sure the Chipset and RAID drivers have been installed. Then double-click the RAIDXpert2 icon on the desktop to launch the RAID utility.

      Step 1:

      Enter the login ID and password (default: "admin"), and then click Submit to launch AMD RAIDXpert2.

       

      GigabyteAMD10.png
      Step 2:

      In the Disk Devices section, left-click your mouse twice on the newly-added hard drive.

       

      GigabyteAMD11.png

      Step 3:

      On the next screen, select Assign as Global Spare and click Confirm.

       

      GigabyteAMD12.png

      Step 4:

      During the rebuild process, you can select the array that is being built (displayed in red) in the Active Volumes section to check the current progress.

       

      GigabyteAMD13.png

      Step 5:

      Then rebuild is complete when the Task State column shows "COMPLETED."
