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 level in the industry now. In that most popular are four levels.
- RAID 0
- RAID 1
- RAID 5
- RAID 1+0
We are going to discuss about the basic RAID level in this article. In RAID level 0(zero) disks are striped so no redundancy of data. This level deliver 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 disk 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.
Lets start configure 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 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
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.
