Redundant Power Supplies
It doesn't matter whether you are running a personal desktop computer or enormous data center facility electricity is what every single computer requires to work as it is supposed to. Even a brief power interruption disrupts any system and, in certain situations, damages the hardware. That is why many critical systems include devices called redundant power supplies. Most of the time, the location of the redundant power supplies is in servers, blade chassis, massive network equipment, and other crucial devices.
When a single piece of computer equipment uses two or more physical power sources, this is known as a redundant power supply. Each power supply can run the equipment by itself, allowing it to continue functioning even if one fails. Under normal circumstances, each power supply will deliver half of the required power (assuming the appearance of two). If one goes down for whatever reason, the other will automatically adapt and provide enough power to the device, ensuring the absence of downtime.
