What is a key characteristic of a Dual-Controller Active-Active System?

A Dual-Controller Active-Active System is designed to enhance performance and reliability by ensuring that both controllers actively handle data processing and requests simultaneously. This characteristic is fundamental as it allows for load balancing; both controllers can share the workload, which optimizes resource usage and minimizes latency. When both controllers are engaged in active processing, the system can also provide higher availability, as it is not reliant on just one controller to manage all tasks.

The active participation of both controllers means that if one experiences failure or degradation, the other can take over without significant interruption in service. This redundancy not only improves performance but also increases the overall resilience of the storage system. Hence, the dual engagement is critical for efficient operation in environments requiring high availability and robust performance.
