Abstract
Detecting coolant leaks in a server system including receiving, by a controller in the server system with nodes stacked vertically, a voltage fault alert from a first node; receiving, by the controller in the server system with nodes stacked vertically, a voltage fault alert from a second node located below the first node; and upon receiving the voltage fault alert from the first node and the voltage fault alert from the second node, powering down, by the controller, one or more nodes located below the second node.
Claims19
A method for detecting coolant leaks in a server system, the method comprising:
- receiving, by a controller in the server system with nodes stacked vertically, a voltage fault alert from a first node;
- receiving, by the controller in the server system with nodes stacked vertically, a voltage fault alert from a second node located below the first node;
- and
- upon receiving the voltage fault alert from the first node and the voltage fault alert from the second node, detecting therefrom that a coolant leak is present in the server system;
- and
- powering down, by the controller and in response to the detected coolant leak, one or more nodes in the server system located below the second node.
An apparatus for detecting coolant leaks in a server system, the apparatus comprising:
- a controller in the server system with a plurality of nodes stacked vertically, the controller comprising:
- a computer processor;
- and
- a computer memory operatively coupled to the computer processor, wherein the controller is configured to:
- receive a voltage fault alert from a first node of the plurality of nodes;
- receive a voltage fault alert from a second node of the plurality of nodes, the second node located below the first node;
- and
- upon receiving the voltage fault alert from the first node and the voltage fault alert from the second node, detect therefrom that a coolant leak is present in the server system;
- and
- power down, in response to the detected coolant leak, one or more nodes of the plurality of nodes located below the second node.
A computer program product for detecting coolant leaks in a server system, the computer program product comprising a non-transitory computer readable medium and computer program instructions stored therein that, when executed, cause a computer to carry out the steps of:
- receiving, by a controller in the server system with nodes stacked vertically, a voltage fault alert from a first node;
- receiving, by the controller in the server system with nodes stacked vertically, a voltage fault alert from a second node located below the first node;
- and
- upon receiving the voltage fault alert from the first node and the voltage fault alert from the second node, detecting therefrom that a coolant leak is present in the server system;
- and
- powering down, by the controller and in response to the detected coolant leak, one or more nodes in the server system located below the second node.
