Embodiment
Referring to Fig. 1, is the system construction drawing of the multi-node system of preferred embodiments of the present invention.Multi-node system 10 comprise some voltage feed units (101,102 ..., 10m), one point of pressing plate 200 and some nodes (301,302 ..., 30n).Wherein, each node can be a server or mainboard.
Voltage feed unit (101,102 ..., 10m) and provide working power for providing to multi-node system 10.Point pressing plate 200 by voltage feed unit (101,102 ..., 10m) working power that provides is converted into various operating voltages, and export to node (301,302 ..., 30n).Dividing pressing plate 200 is a programmable chip, concrete as NXPLPC1768.
This multi-node system 10 also comprise with voltage feed unit (101,102 ..., 10m) and node (301,302,, 30n) the identical switch of quantity (411,412 ..., 41m, and 401,402 ..., 40n), one end is connected with a point pressing plate 200, switch (411,412 ..., 41m) the other end connect respectively a voltage feed unit (101,102,, 10m), switch (401,402 ... other end 40n) connect respectively a node (301,302 ..., 30n).
Fig. 2 is the module map of the reduction power consumption system that is applied to multi-node system of preferred embodiments of the present invention.This reduction power consumption system runs on point pressing plate 200.This reduction power consumption system 20 comprises a monitoring modular 201, a power computation module 202, consumption reduction determination module 203 and a control module 204.The concrete function of modules is described in connection with Fig. 3.
Fig. 3 be preferred embodiments of the present invention multi-node system is reduced to the method flow diagram of power consumption.The method runs on point pressing plate 200.
In step S21, all nodes of monitoring modular 201 lasting detecting (301,302 ..., 30n) voltage and current information;
In step S22, power computation module 202 according to detecting all nodes (301,302 ..., 30n) voltage and current information calculate all nodes (301,302 ..., 30n) power consumption;
In step S23, consumption reduction determination module 203 is determined the node that needs consumption reduction according to default node consumption reduction scheme, if default node consumption reduction scheme is that the node that power consumption is the highest is while needing the node of consumption reduction, consumption reduction determination module 203 is by all nodes (301,302,, 30n) power consumption sort, determine node that consumed power is the highest for needing the node (as node 302) of consumption reduction;
In step S24, control module 204 is opened the switch (as switch 402) that the node the highest with this consumed power (as node 302) is connected, thereby closes the node that this consumed power is the highest;
In step S25, power computation module 202 calculate all nodes (301,302 ..., 30n) power consumption summation;
In step S26, consumption reduction determination module 203 is determined the voltage feed unit that needs consumption reduction according to default voltage feed unit consumption reduction scheme, if default voltage feed unit consumption reduction scheme is the voltage feed unit that uses the power consumption summation minimum number that can meet all nodes, while closing other voltage feed unit, consumption reduction determination module 203 calculates some or several voltage feed units provides power to be greater than all nodes (301, 302, power consumption summation 30n), and select the voltage feed unit that uses voltage feed unit minimum number, other voltage feed unit is the voltage feed unit that needs consumption reduction, as being greater than all nodes (301 at the power that provides of a voltage feed unit (as voltage feed unit 101) only, 302, when power consumption summation 30n), consumption reduction scheme can be closes other voltage feed units (102, 10m),
In step S27, control module 204 open the switch that the voltage feed unit that need to lower consumption with this is connected (as switch (412 ..., 41m)), thus disconnect with need consumption reduction voltage feed unit (as voltage feed unit (102 ..., 10m)) connection.
In a word; those skilled in the art will be appreciated that; above execution mode is only for the present invention is described; and be not used as limitation of the invention; as long as within connotation scope of the present invention, within the appropriate change that above embodiment is done and variation all drop on the scope of protection of present invention.
