- Abstract
- A power control apparatus for a cluster system, includes a cluster including a plurality of nodes, each equipped with a battery; and a power control unit connected to the cluster over a network and configured to monitor power management information and performance information of the cluster and to set a power capping threshold based on the monitored power management information and performance information of the cluster. Accordingly, the power control unit enables power of the cluster to be limited by turning on and off the batteries when power of the cluster system increases up to the power capping threshold.
