Two power supplies are installed for each mission-critical server. What concept does this illustrate?

Explanation:
Redundancy is being demonstrated by installing two power supplies for each mission-critical server. The idea is to have a backup power path so if the primary supply fails, the other can take over and keep the server running without interruption. This directly reduces the risk of a single point of failure and helps maintain continuous operation. It supports high availability and is a common tactic in fault-tolerant designs, but the specific concept illustrated is redundancy. Load balancing isn’t about duplicating components in a single device; it distributes work across multiple devices to optimize performance.
