What type of disk redundancy can be implemented to enhance the performance of a SQL database deployment?

Multipathing
RAID
Masking
Tiering

The correct answer is: RAID

Implementing RAID (Redundant Array of Independent Disks) for disk redundancy in a SQL database deployment enhances performance in several ways. RAID combines multiple physical disks into a single logical unit, which can improve both data redundancy and read/write performance depending on the type of RAID level used. For example, RAID 0 offers striping, which distributes data across multiple disks, thereby increasing data access speed due to simultaneous disk operations. This level of performance enhancement is crucial for SQL databases that require quick read and write times to handle transactions efficiently. Moreover, certain RAID configurations, such as RAID 10, provide both redundancy and performance benefits, as they combine mirroring and striping. This means that while data is securely duplicated across multiple disks (improving fault tolerance), it can also be read from and written to multiple physical disks simultaneously, further boosting performance. By choosing RAID for disk redundancy, a SQL database can achieve optimal performance while ensuring data integrity and availability, making it a suitable choice in environments where database responsiveness is critical.
