6 Creating RAID Using Lifecycle Controller
1 What is RAID?
RAID―Redundant Array of Inexpensive/Independent Disks is a storage technology that combines multiple
hard disk drives (HDDs) into a logical unit. Data is distributed across the storage disk drives in one of the
methods called "RAID levels", on the basis of level of redundancy and performance required.
There are multiple methods in which you can create RAID on PowerEdge servers of Dell. This whitepaper
focuses only on the methods to create RAID using RAID configuration wizard in Lifecycle Controller GUI.
