Which feature of VPLEX improves fault tolerance?

The feature that enhances fault tolerance in VPLEX is the use of redundant components. This design ensures that if one component fails, another can take over, allowing the system to continue operating without interruption. Redundancy is a critical principle in high-availability systems, as it mitigates the risk of single points of failure. By incorporating multiple instances of critical components, such as power supplies, processors, or network links, VPLEX can maintain service availability and protect against data loss.

Power management primarily focuses on efficiently using and managing energy resources, while data striping involves distributing data across multiple disks to improve performance but does not inherently contribute to fault tolerance. Data compression is useful for saving storage space but does not provide any mechanism for ensuring system reliability in the face of hardware failures. Thus, redundant components specifically provide a clear and direct enhancement to fault tolerance.
