In a server that requires high availability, multiple power supplies might be used. What is the primary reason for employing this configuration?
The additional power supplies are intended to supply power to more peripherals and expansion cards added to the server
Having more than one power supply enables the server to draw power from two separate phases of AC power for load balancing
The additional power supplies deploy more fans, enhancing thermal management through superior airflow
Multiple power supplies allow for failover if a power supply unit fails, mitigating the risk of system downtime
