Configuring the power redundancy

To configure the power redundancy, use the information in this topic.

Available fields in the Power Redundancy section include the following:

  • Redundant (N+N): There are two or more independent power sources that are capable of supplying power to the system simultaneously. This means that if one or more power sources fails, the other source(s) can continue to supply power to the system without any interruption. N+N redundancy provides a high level of fault tolerance and ensures that the system remains operational even in the event of multiple failures.
    • Zero Output Mode: Once enabled under Redundant configuration, some PSUs will automatically enter into standby state under light load conditions. In this manner, the remaining PSU delivers the entire power load to increase efficiency.
  • Redundant (N+1): There is one primary power source that is capable of supplying power to the system. Additionally, there is at least one backup power source that is available to take over if the primary source fails. The backup source is designed to provide enough power to keep the system running until the primary source can be repaired or replaced. N+1 redundancy provides a lower level of fault tolerance compared to N+N redundancy.
  • Non-redundant mode: In this mode, the server is not guaranteed to remain operational if a power supply is lost. The server will throttle if a power supply fails in an attempt to remain running.
