This article explains the creation and configuration" of NVMe RAIDs in Linux systems with SupremeRAID controllers. The controllers of the manufacturer Graid Technology Inc. uses GPU technology and a special software for the arrays. They are wireless usable and avoid additional load on working storage or main processor.

Installation of controller

Before you can set up a RAID of a SupremeRAID controller, the required drivers have to be installed on your Windows server system. The following paragraphs explain the procedure.

Requirements

Minimum requirements Hardware:

  • CPU: 2GHz or more with at least 8 cores
  • RAM: 16 GB
  • PCIe: Gen3 or Gen4 x16
  • NVMe: compatible data carriers

You will find the supported Linux derviates and Kernel versions as well as a list of compatible data carriers, latest drivers and minimum requirements on the manufacturer's website .[1]

Installation of driver

To install Supreme GRAID controllers duly, you have to install the hardware driver first.

Required files

Please download the following files:

Performance

These files must be moved to your system. There are different opportunities for this. We use a USB stick in these instructions. The following steps have to be performed:

  1. Connect the USB stick with your system
  2. Create with mkdir <ordnername> a target folder for the drivers
  3. Navigate with cd <ordnername> to the target folder
  4. You will receive the directory path with pwd for the mount point of the USB stick
  5. The command lsblk shows the path of the USB stick
  6. Mounting of the USB stick: sudo mount /USB-StickPfad /target file
  7. Navigate to the target file
  8. Make the file graid-sr-pre-installer executable. You achieve this by using sudo chmod +x graid-sr-pre-installer-1.6.1-134-x86_64.run
  9. Afterwards the drivers are installed with the command sudo ./graid-sr-pre-installer-1.6.1-134-x86.run

You will find the exemplary performance in the following gallery:

  • Create target folder with mkdir and verify with ls.

  • Find out the mount point and path of the USB stick.

  • Mounting of the USB stick.
    Mounting of the USB stick.
  • Make driver file executable and install driver.
    Make driver file executable and install driver.

Installation of installer file

Repeat the above steps with both drivers: graid-sr-installer-xxx.run. If you execute this file, you will find yourself in a graphical user interface. Follow the steps of the installer and let it run through.

RAID configuration

After the installation, you can start with the configuration of your desired RAID arrays. This can be performed with a GUI or via command line.

Hereafter you will find instructions using the graphical user interface.

Connection with GUI

To create a RAID, you can connect another client to the GUI: For this, you have to know the IP address of the target system. Use the following command for this:ip a.

After this, open your browser and type in https://[IP-Adresse]:50060. You will find yourself on this interface:

  • You have to type in your license key when you are connected with the GUI for the first time.

  • You can create a RAID directly.

  • Choose the NVMes for the RAID compound.

  • Verify the configuration.If you are satisfied, confirm with a click on Apply.
    Verify the configuration.If you are satisfied, confirm with a click on Apply.
  • The process has been concluded successfully. With Go to dashboard, you will be forwarded to the main screen of the GUI.
    The process has been concluded successfully. With Go to dashboard, you will be forwarded to the main screen of the GUI.
  • Here, you can see the dashboard.
    Here, you can see the dashboard.
  • The RAID will be displayed in the operating system as gdg0n1.
    The RAID will be displayed in the operating system as gdg0n1.

Configuration of hot spare NVME

A hot spare data carrier is an emergency data carrier in a RAID compound. The RAID uses a "hot spare" if another data carrier of the array fails.

The instructions for the configuration of a "hot spare" data carrier in the GUI can be found in the following:

  • Navigate to the menu RAID Management > Physical Drives.
    Navigate to the menu RAID Management > Physical Drives.
  • Click on the NVMe that is intended for "hot spare". After this, click on hot spare. You can also see that this one has not been configured as hot spare yet.
    Click on the NVMe that is intended for "hot spare". After this, click on hot spare. You can also see that this one has not been configured as hot spare yet.
  • You can now choose if you want to have the NVMe configured as global hot spare or for a certain drive group.
    You can now choose if you want to have the NVMe configured as global hot spare or for a certain drive group.
  • The hot spare configuration has been successful.
    The hot spare configuration has been successful.
