Understanding RAID principles and configurations
RAID, which stands for Redundant Array of Independent Disks or sometimes Redundant Array of Inexpensive Disks, is a critical technology in modern IT infrastructure for enhancing data protection and system reliability. The term “Independent Disks” emphasizes that the disks can be separate and distinct units. In contrast, “Inexpensive Disks” highlights that RAID can effectively utilize low-cost drives to achieve high availability and fault tolerance. By combining multiple physical disks into a single logical unit, RAID allows data to be distributed, mirrored, or both across these disks, thereby creating redundancy that significantly increases fault tolerance. This redundancy ensures that even if one or more disks fail, the data remains accessible, minimizing the risk of data loss and system downtime. However, while RAID provides robust protection against hardware failures, it is not a comprehensive data protection...
