RAID Configuration
RAID (Redundant Array of Independent Disks) Configuration is a data storage virtualization technology that combines multiple physical disk drives into one or more logical units for data redundancy, performance improvement, or both. It distributes data across drives using various RAID levels (e.g., RAID 0, 1, 5, 10) to achieve specific goals like fault tolerance, increased speed, or capacity optimization. This concept is widely used in servers, storage systems, and high-availability computing environments to protect against disk failures and enhance data reliability.
Developers should learn RAID Configuration when working with systems that require high data availability, such as database servers, file servers, or cloud infrastructure, to prevent data loss from disk failures. It is essential for roles involving system administration, DevOps, or data-intensive applications where uptime and data integrity are critical, as it provides redundancy and can improve read/write performance through striping or mirroring techniques.
