RAID configuration
Using a Redundant Array of Independent Disks (RAID) to store data remains one of the most common and 
cost-efficient methods to increase server's storage performance, availability, and capacity. 
RAID increases performance by allowing multiple drives to process I/O requests simultaneously. RAID can 
also prevent data loss in case of a drive failure by reconstructing (or rebuilding) the missing data from the 
failed drive using the data from the remaining drives.
RAID array (also known as RAID drive group) is a group of multiple physical drives that uses a certain 
common method to distribute data across the drives. A virtual drive (also known as virtual disk or logical 
drive) is a partition in the drive group that is made up of contiguous data segments on the drives. Virtual drive 
is presented up to the host operating system as a physical disk that can be partitioned to create OS logical 
drives or volumes.
An introduction to RAID is available at the following Lenovo Press website:
