1. A server rack system, comprising:
- a plurality of power supply units;
a monitoring circuit for monitoring the plurality of power supply units;
a rack management controller (RMC) for monitoring the plurality of power supply units;
a plurality of server nodes; and
a backplane controller communicatively coupled to the monitoring circuit, the RMC, and the plurality of server nodes;
wherein the backplane controller is configured for lowering an operation status of at least one of the server nodes or forcibly shutting down one of the server nodes, in response to a command from the monitoring circuit or the RMC,wherein the monitoring circuit is configured to detect whether a quantity of power supply units that fails to output a normal voltage is over a first threshold, andwherein the RMC is configured to detect whether the quantity is over a second threshold.

Abstract
A server rack system including a plurality of power supply units, a monitoring circuit, a rack management controller (RMC), and a plurality of server nodes is provided. The monitoring circuit is for monitoring the power supply units. The RMC is for monitoring the power supply units. When the monitoring circuit and/or the RMC finds that at least one of the power supply units failed to output a normal voltage, an operation status of the server nodes is lowered or at least one of the server nodes is forcibly shut down.

6. A power management method applicable to a server rack system including a monitoring circuit, an RMC, and a plurality of server nodes, the power management method including:
-
determining, via the monitoring circuit, that a first quantity of the plurality of power supplies failing to output a normal voltage is over a first threshold; in response to determining that the first quantity is over the first threshold, lowering an operation status of the server nodes or forcibly shutting down at least one of the plurality of server nodes, or in response to determining that the first quantity is not over the first threshold, determining, via the RMC, that a second quantity of the plurality of power supply units failing to output the normal voltage is over a second threshold; and in response to determining that the second quantity is over the second threshold, lowering the operation status of the server nodes or forcibly shutting down at least one of the server nodes. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13)

14. A power management method applicable to a server rack system including a monitoring circuit, an RMC, and a plurality of server nodes, the power management method including:
-
determining, via the monitoring circuit, that a first quantity of the plurality of power supplies failing to output a normal voltage is over a first threshold; in response to determining that the first quantity is over the first threshold, lowering an operation status of the server nodes or forcibly shutting down at least one of the plurality of server nodes, or in response to determining that the first quantity is not over the first threshold, determining, via the RMC, that a second quantity of the plurality of power supply units failing to output the normal voltage is over a second threshold; and in response to determining that the second quantity is over the second threshold, lowering the operation status of the server nodes or forcibly shutting down at least one of the server nodes, wherein, setting of the first threshold and the second threshold is related to a loading state of the server rack system. - View Dependent Claims (15, 16, 17, 18, 19)
