This step by step tutorial is to demonstrate the basic steps for configuring RAID 0 in HP Server and is aimed at beginners and above.

RAID is the short form of Redundant Array of Independent Disks which is a way of storing the same data in different places on multiple hard disks.  There are different RAID levels in the industry now and most popular are four levels

  • RAID 0
  • RAID 1
  • RAID 5
  • RAID 1+0

In this tutorial we are going to discuss about the basic RAID level. In RAID level 0(zero) disks are striped so no redundancy of data. This level delivers the best performance without fault-tolerance. I have taken one HP Server to show you how we can configure RAID level 0. We need to have minimum two disks to configure RAID 0. When one of disk fails, you will lose data as we have striped the drives. So it is very important that when you use RAID 0 , you need to take regular backup of your data. Also this level is not recommended for critical production servers.

Let’s start configuring RAID in a HP Server. Power on the Server and wait for the Array Controller ROM utility to prompt you to press F8 to run Option ROM configurations for Arrays.

Press F8 to enter the utility then you will get the Array controller utility to create logical drives.  Select Create logical drive and press Enter.

Here we can see  the Available Physical Drives. Choose the drives you want to add to RAID 0 logical drive. Remember RAID-0 required minimum two disks. so select at least two drives. Once you selected drives use tab button to navigate  to the next option RAID Configuration and choose RAID 0.

Press Enter to create the logical drive.

Press F8 to Save the configuration. This will create the RAID 0 Logical Drive.

Image

Press Enter to continue. That will take you to the main menu again. It is good to verify the Logical drive we created. For that select View Logical Drive and press Enter

Image

That will show you the logical drive you have just created. Since I have selected all eight Physical disks (146GB each disk) available, for this logical drive we have got 1 TB capacity.

You can Select the Logical Drive and press  Enter to see the physical disk array(total number of disk used in this RAID-0 local drive.

You need to press ESC to return to main menu. when you done press ESC again to quit from the utility and server will continue the boot process.

congratulation !! and there you have created RAID 0 in HP Server !
