An Internet service provider must support highly available storage arrays. Which of the following technologies supports the ability to swap hardware without downtime?

Hot pluggable components are specifically designed to be inserted or removed from a system while it is running and powered on. This capability is crucial for high-availability systems as it allows for the replacement of faulty parts, such as drives or power supplies, without causing any downtime or service interruption.

Fiber attached storage controllers refer to the interface technology used for connecting storage, not a feature that enables hardware swapping without downtime.

RAID 5 configuration provides data redundancy and fault tolerance for disk failures, but it does not facilitate the physical swapping of hardware components while the system is operational.

Dual power supplies provide power redundancy to prevent downtime from a single power supply failure, but they do not enable the hot-swapping of other system components.
