RAID stands for Redundant Array of Independent Disks and it involves two key design goals: Increased data reliability and increased input/output (I/O) performance. When multiple physical disks are set up to use the RAID technology, they are said to be in a RAID array. This array distributes data across multiple disks, but the array is seen by the computer user and operating system as one single disk. RAID can be set up to serve several different purposes.
Different types of RAID levels
Different types of RAID levels are available. Some are basic RAID levels and some are a combination of basic levels.
Here, RAID 0, RAID 1, and RAID 5 are the basic RAID levels and the remaining RAID 6, RAID 10, RAID 50, and RAID 60 are the combination of the basic RAID levels.
Each RAID level is defined for a specific purpose. Read through the following table to get a better understanding about the various RAID levels.
Supported RAID levels in IBM Power platforms
The following RAID levels are supported by IBM Power hardware.
Perform the following steps to configure RAID 5 on the Power platform.
This kind of setup is mainly for hardware redundancy with respect to disks.
