Redundant power的意思
"Redundant power" is a term used in the context of power supply systems, particularly in data centers, server rooms, and other critical infrastructure where continuous operation is essential. It refers to a system that has multiple power sources or pathways to ensure that the equipment remains operational even if one of the power sources fails.
The goal of redundant power is to provide a backup power source that can immediately take over in the event of a failure, minimizing downtime and ensuring that the equipment remains powered. This is particularly important for systems that cannot afford to go offline, such as servers, telecommunications equipment, medical devices, and other critical applications.
Redundant power systems can take several forms, including:
-
Dual Power Supplies: Many servers and other critical devices are designed with two power supplies. If one power supply fails, the other can continue to provide power to the device.
-
Uninterruptible Power Supplies (UPS): A UPS provides a buffer between the main power source and the equipment by using batteries to provide power for a short period of time if there is a power outage.
-
Diesel Generators: Large data centers and facilities may have diesel generators as a backup power source. These can provide longer-term power in the event of a prolonged outage.
-
Redundant Power Paths: Some systems have multiple power paths from the power source to the equipment. If one path fails, the equipment can still receive power from the other paths.
-
Power Distribution Units (PDUs): PDUs can be designed with multiple power inputs and the ability to switch between them, providing a form of redundancy.
Redundant power is just one aspect of overall system redundancy, which can also include redundant network connections, cooling systems, and other infrastructure components to ensure high availability and reliability.
