If power is lost to the second power supply of a server, it depends on the type of power supply redundancy that is implemented in the server. There are two types of power supply redundancy: N+1 and 1+1.
In N+1 power supply redundancy, the server has one extra power supply in case one fails. If power is lost to the second power supply in this scenario, the server will remain in operation because the extra power supply is sufficient to handle the load. However, if the first power supply fails, the server will shut down gracefully to avoid data loss or corruption.
In 1+1 power supply redundancy, the server has two power supplies that are both capable of handling the server's load. If power is lost to the second power supply in this scenario, the server will continue to operate normally because the first power supply is still functioning.
It is important to note that automatic transfer switches and generators are not typically used in server power supply redundancy setups. These are typically used for power backup in case of a larger power outage, such as during a natural disaster or other emergency situation.
Additionally, the UPS (Uninterruptible Power Supply) is used to provide temporary power to the server in case of a power outage. If the UPS exceeds its maximum load, it can cause damage to the equipment connected to it. Therefore, it is important to properly size the UPS for the equipment it will be supporting.
