Management of power consumption in large computing clusters
Management of power consumption in large computing clusters is disclosed herein. According to an aspect, a computing device comprising a power manager may be configured to receive, via a communication interface, information associated with the cluster of computing nodes. The power manager of the computing device may also be configured to determine whether a switch is coupled to an inactive computing node of the cluster of computing nodes based on the received information. Further, the power manager of the computing device may be configured to communicate a command to the switch to remove power supplied to a switch port of the switch coupled to the inactive computing node in response to determining that the switch is coupled to an inactive computing node of the cluster of computing nodes.
1. A computing device comprising:
a communication interface configured to communicate with a cluster of computing nodes and a power manager of a plurality of switches coupled to each computing node of the cluster of computing nodes; and
an activity scheduler comprising at least one processor and memory configured to:
receive, via the communication interface, information associated with the plurality of switches;
receive a request to schedule activity for an inactive computing node of the cluster of computing nodes;
determine whether one of a switch and a switch port of the switch coupled to the inactive computing node of the cluster of computing nodes is powered down based on the received information;
in response to determining the one of the switch and the switch port of the switch is powered down, communicate a command to the power manager to supply power to one of the switch and the switch port of the switch;
schedule activity for the inactive computing node to activate the inactive computing node.
2. The computing device of claim 1 , wherein the information associated with the plurality of switches indicates that the one of the switch and the switch port of the switch is powered down.
3. The computing device of claim 1 , wherein the command comprises information identifying the inactive computing node.
