Description

A method and cabinet system capable of realizing SMARTRACK energy saving

technical field

The invention relates to the field of power supply for server cabinet systems, in particular to a method and a cabinet system capable of realizing SMART RACK energy saving.

Background technique

With the continuous expansion of the application scope of the Internet, many businesses in people's work and life are showing the development trend of informatization. The computing performance requirements for network servers are increasing, and various high-density cabinet server systems have come out one after another. This type of server cabinet is composed of many computing nodes and related management units and monitoring units. Under the scheduling of the management unit, the resource scheduling of all computing nodes of the cabinet server system is realized, and the computing capacity of the system is maximized. However, due to the huge data processing volume of this kind of high-density rack server system, its overall power consumption is also very huge.

The usual server power supply adopts the power supply method of configuring one power supply per machine. This method is generally low in power supply efficiency, and in the face of computer rooms with high deployment density requirements, this power supply method often appears to be stretched. In view of this dilemma, the centralized power supply method of the cabinet was proposed. The centralized power supply mode is to gather multiple power supply modules together through a power supply backplane module to realize redundant power supply; then connect to the power supply bus through the output end of the power supply backplane, all computing nodes in the cabinet system and The cooling subsystems are powered by the power supply bus. This power supply mode can effectively increase the cabinet deployment density of the cabinet, and at the same time improve the power supply efficiency of the entire cabinet system and reduce energy consumption. However, this power supply method has a disadvantage: when the entire cabinet system is under low-load operating conditions, the load distributed by each power module will be very small. Since the efficiency of the power module is generally lower under low load conditions, the efficiency reaches the maximum when the load reaches about 50%.

Contents of the invention

The technical task of the present invention is to provide a method for realizing energy saving of SMART RACK aiming at the deficiencies of the above-mentioned prior art. The method can keep the system power supply module in a high-efficiency working state all the time, thereby maximizing the energy efficiency of the system and further reducing energy consumption.

The further technical task of the present invention is to provide a SMART RACK energy-saving cabinet system.

The Smart Rack refers to a Rack server cabinet system that can flexibly configure the type and quantity of nodes according to the specific needs of users.

Technical task of the present invention is realized in the following manner: a kind of method that can realize SMART RACK energy-saving, it is characterized in that: comprise system monitoring module, system management module, power management unit and power module monitoring unit,

The system monitoring module is used to realize the monitoring function of the container data center, including UPS supply voltage, supply current, total power of the container data center, working status of the computing node, IPMI interface address of the computing node, and each fan in the heat dissipation subsystem. Speed information, ambient temperature, humidity information;

The system management module coordinates the work of the computing node subsystem, heat dissipation subsystem, and power management unit in the cabinet system through the information collected by the system monitoring module, and at the same time ensures the normal data exchange between the cabinet system and the outside world;

The power module monitoring unit is used to collect the change information of the output power of each power module in real time;

When the system is running under light load status, the power module monitoring unit will collect the output power information of each power module in real time and feed it back to the power management unit; the power management unit processes the power data and sends out control signals to decide whether to Turn off some power modules to ensure that the remaining power modules can work under 50% load as much as possible;

When the system changes from a light-load state to a heavy-load state, the power management unit will communicate with the system management module to confirm whether it is necessary to turn on the power module and turn on several power modules to ensure the normal operation of the entire system.

Further, when the system is in a light-load state, when the output power of the power module collected by the power module monitoring unit is lower than a specific value, the power management unit sends a signal to shut down at least one power module, so as to ensure that the remaining power modules can operate at 50% load. work under conditions. the

The specific value is determined by the actual output power of the power supply module. Since the efficiency of the power module is the highest under the condition of 50% load, in order to ensure that the efficiency of the entire power module can always reach the highest level, it is required that a single power module in the power module can share 50% of the load. The determination of the power value has the following situations:

Assume that the actual output power of the power supply module is P _T , and the rated output power of a single power supply module is P _S ; when four power supply modules work at the same time, the actual output power of a single power supply module is P _O . Then there are:

A. When 3P _{S ≤PT} ≤4P _S , the power value is 0.75P _S ; at this time, four power modules are used for power supply;

B. When 2P _S ≤ P _T <3P _S , the power value is 0.5P _S ; at this time, three power supply modules are used for power supply;

C. When P _S ≤ P _T <2P _S , the power value is 0.25P _S ; at this time, two power supply modules are used for power supply;

D. When 0≤P _T < _PS , the power value is 0.125P _S ; at this time, a power supply module is used for power supply.

When the entire Rack cabinet system is under light load, some of the power modules are turned off through the system management module, so that a few or even one power module can work. The working status of all power modules is monitored in real time by the power module monitoring unit, and the data obtained from the monitoring is submitted to the power management unit for calculation and processing, so as to determine the number of power modules to be turned off. When the system is in a high-load working state, the power management unit performs corresponding processing actions through the working status information of the computing nodes and the cooling subsystem captured by the system monitoring module, and sends a signal to restart the power module that was turned off at light load. In this way, by adding a power management unit, a power module monitoring unit, and a system monitoring module to coordinate work in the cabinet system, the working state of the power module is adjusted in real time according to the load status of the system, so that the system power module is always in a high-efficiency working state. Thereby, the maximum energy efficiency of the system is achieved, and the effect of further reducing energy consumption is realized.
