Description

A Strategy-Based Method for Dynamic Allocation of Computer Power

technical field

The invention relates to the field of computer monitoring and management, in particular to a strategy-based method for dynamically distributing computer power.

Background technique

As the core carrier of information services, a large number of computers, such as servers, usually have to run continuously for a long time, resulting in huge power consumption. According to a report released last year by the U.S. Energy and Environmental Protection Agency, the energy consumption of global servers has accounted for 1% of the total global energy consumption, and the energy consumption of servers will double within 5 years. According to a report by the International Data Corporation (IDC), in 2007, China's total power consumption for server operation and cooling was equivalent to the annual power generation of Gezhouba Power Station. Behind the high energy consumption of servers lies a serious energy and environmental crisis. According to IDC data, every reduction of 1,000 traditional servers can save about 5.4 million kilowatt-hours of electricity per year, which is equivalent to saving 1,944 tons of coal. It can be seen that controlling server energy consumption is of great significance for protecting the environment and promoting economic development.

Usually the energy-saving technology on the server is mainly for the energy-saving technology of the processor, such as IBM's Power Islands technology used on Power5, Intel's SpeedStep and AMD's PowerNow! Technology, Intel's Demand Based Switching and other technologies. However, these technologies only control the voltage and frequency of the microcontroller, so the scope of energy saving is limited, especially when the system business load is low, the server is still in normal operation, and its power consumption lacks effective control.

Contents of the invention

The technical task of the present invention is to provide a strategy-based method for dynamically distributing power of a computer to save energy by analyzing an appropriate strategy according to the business load and forcibly controlling the output power of the power supply when it is idle.

The technical task of the present invention is realized in the following manner. According to the customer's business load, a corresponding working strategy is formulated, and then the output power of the power supply is controlled according to the established strategy; the system structure includes a customer's business load monitoring unit, a Embedded power control unit, strategy analysis and implementation unit; customer business load monitoring unit is mainly responsible for monitoring and statistics of customer business load; the embedded power control unit installed in the power supply is the carrier of this method, responsible for controlling the power supply on the basis of policy regulations power; the strategy analysis and implementation unit is the core of the method, responsible for strategy analysis, formulation and implementation; the steps of the method are:

(1), monitor the customer business load situation through the customer business load monitoring unit, and make statistics on the customer business load;

(2) The strategy analysis and implementation unit analyzes the customer's business load, and formulates a power management strategy suitable for the business load according to the actual business situation;

(3) The strategy analysis and implementation unit executes the strategies formulated above; if the customer's business load meets the formulated policy conditions, the embedded power control unit installed in the power supply controls the output power of the power supply; if the customer's business load does not meet the established policy conditions Policy conditions, then maintain the current power.

Monitor the load of customer business through the customer business load monitoring unit; the strategy analysis and implementation unit analyzes the busy and idle time periods of the business, and formulates the corresponding power interval strategy according to the busy and idle time of the business, such as the value of power limit , the time when the strategy takes effect, and the duration of the strategy; within the time when the strategy takes effect, the embedded power control unit installed in the power supply will automatically reduce the power of the power supply to the limited value according to the instruction.

The user can automatically monitor the business load through the software, and analyze and formulate a strategy according to the actual business situation. During the effective time of the strategy, the output power of the power supply can be controlled according to the established strategy.

A method for dynamically allocating computer power supply based on strategy of the present invention has the following advantages:

1. If the customer's business load meets the established policy conditions, the policy will take effect; within the time when the policy takes effect, the embedded power control unit installed in the power supply will automatically drop to the limited value according to the instruction, so as to achieve the purpose of energy saving;

2. In the system structure, the user can automatically monitor the business load through the software; in this way, the purpose of reducing the power consumption of the computer can be achieved without affecting the customer's business, and the purpose of energy saving can be achieved;

3. The design is reasonable and the use is convenient; thus, it has good promotion and use value.
