Understanding RAID Concepts
Storage Management uses the Redundant Array of Independent Disks (RAID) technology to provide Storage Management
capability. Understanding Storage Management requires an understanding of RAID concepts, as well as some familiarity with
how the RAID controllers and operating system view disk space on your system.
What Is RAID?
RAID is a technology for managing the storage of data on the physical disks that reside or are attached to the system. A key
aspect of RAID is the ability to span physical disks so that the combined storage capacity of multiple physical disks can be
treated as a single, extended disk space. Another key aspect of RAID is the ability to maintain redundant data which can be
