A data center generally refers to a building for storing IT equipment, and the data center may include a plurality of functional rooms, such as a power distribution room, a parallel room, an IT machine room, and so on, in order to ensure the normal operation of the IT equipment. The IT equipment, such as servers, storage devices, etc., is generally placed in a cabinet of an IT machine room. Before the newly-built data center is put into use, the operation conditions of all aspects of the newly-built data center can be tested in advance so as to eliminate hidden dangers in advance. The load carrying capacity of circuit links such as a cabinet and an air conditioner in an IT machine room is an important index for ensuring the normal operation of the IT equipment, and in the prior art, a dummy load is used for replacing one or more IT equipment (usually a server) to be connected into the circuit to simulate the actual operation parameters of the IT equipment, so that trial operation is carried out, and the load carrying capacity of the circuit is obtained. In the current test, the power of the dummy load is single and unadjustable, or the test can be performed only according to the power and current of the IT equipment when the IT equipment is fully loaded or half loaded, and the IT equipment generates nonlinear power change according to the use intensity when the IT equipment is put into use, and the IT equipment is not operated under full-load or half-load power for most of time, so the current test means cannot truly simulate the operating environment of the server during operation, and the test result is not true.
As shown in fig. 1, the present application provides a load testing apparatus for a data center, including: a housing 1, a load circuit (as shown in fig. 3, this figure is only one electrical connection form of the load circuit, the load circuit of the present scheme may also adopt other electrical connection forms), and a load module 3; the load module 3 comprises a plurality of power consuming units 301, and the load testing apparatus is configured to enable part or all of the plurality of power consuming units 301 to be connected to the load circuit so as to adjust the overall load power of the load testing apparatus; the load circuit, load module 3 is located within the housing 1.
When load testing is carried out, the load testing device of the scheme is connected into a testing circuit to carry out load capacity testing of the circuit. A plurality of power consuming units 301 of the load module 3 are partially or completely connected to the load circuit to adjust the overall load power of the load testing apparatus, so that the load power has the characteristic of multi-gear adjustability. Compared with the prior art, the adjustable characteristic of many gears not only can simulate the half-load or full-load running state of IT equipment, can also simulate the running state that the IT equipment produced the nonlinear power change according to the use intensity according to actual conditions, or simulate the running state of other different power change laws of IT equipment in the actual operation process. Due to the performance, the load testing device can simulate the power change and the running state of a large number of IT equipment such as servers, cabinets and the like in each time interval after the data center is put into use more truly, more accurate test data are obtained, and hidden dangers in the aspect of loading capacity of the data center are eliminated in advance. The number of the power consumption units 301 may be 2, 3 or more, and the specific number may be selected according to actual needs, which is not limited in this application. In addition, the power consumption unit 301 may be connected to the load circuit in a pluggable manner, or each power consumption unit 301 may be provided with a switch 201 to control the power consumption unit 301 to be partially or completely connected to the load circuit, so as to achieve the purpose of adjusting the load power of the entire load testing apparatus.
Optionally, the power consuming unit 301 comprises a resistor R.
The resistor R with the determined resistance value is selected as the power consumption unit 301 to be connected into the load circuit, the tested power consumption power can be directly converted according to the current or voltage of the circuit and the resistance value number of the resistor R and an ohm law and a power calculation formula without considering redundant interference factors, and therefore the convenience is brought when the number of the power consumption units 301 (resistors R) is selected to be connected into the load circuit. The resistor R serving as the power consumption unit 301 can simulate the actual running state of the data center more truly, quickly and simply, and the testing efficiency is improved.
Preferably, the resistance R is a low temperature coefficient resistance R.
The low temperature coefficient resistor R is also called a low temperature drift resistor R, the general temperature stability is strong, the resistance value of the resistor R is only slightly changed when the temperature is changed, after the resistor R is connected into a load circuit, the power of the resistor R is slightly influenced by the temperature change, the power change of the resistor R with a set number is closer to an expected value, and the test precision can be further improved. For example, the resistance of the conventional resistor R increases according to the temperature increase, and the final power deviation is large. When the 10 single low-temperature coefficient resistors R with the resistance value of 400 omega are partially or completely connected into the load circuit, the resistance values of the resistors can not be obviously changed according to the increase of the temperature, and the resistors can be adjusted corresponding to 10 gears with the power of 120W-1200W.

Specifically, the power adjusting knob 4 is arranged on the housing 1, and is electrically connected with the power consuming units 301 (preferably, the low temperature coefficient resistor R), and when the number of the power consuming units 301 connected to the load circuit needs to be adjusted, if the power of the simulated load is changed rapidly during use, the power adjusting knob 4 is only required to be pushed outside the housing 1 to operate, so that the adjusting time is greatly saved, the power adjustment is faster and more convenient, and the operation process of the data center is simulated more truly.
Optionally, the load circuit further includes a switch 201, a power interface 202; the switch 201 is configured to control the power interface 202 to be disconnected from the load circuit. The power interface 202 is used for connecting a power supply to supply power to the whole load circuit. Due to the arrangement of the switch 201, when an accident occurs in the testing process, the power is conveniently and timely cut off, so that a cable or a load testing device is not burnt.
Optionally, a power supply hole 101 is further formed in the housing 1, and the power supply interface 202 is connected to a power supply through the power supply hole 101. The power supply hole 101 is formed in the shell 1, so that the power supply and the power supply interface 202 can be connected and fixed on the shell 1, and the situation that cables are pulled and power is cut off accidentally in the test process when more devices and cables are used is avoided.
Optionally, at least one fan 5 is further included, the fan 5 is disposed in the housing 1, and the fan 5 is electrically connected to the load circuit (refer to fig. 3); the casing 1 is provided with air outlets 102 corresponding to the number of the fans 5 at positions corresponding to the fans 5. The number of the exhaust ports 102 may be configured to be equal to the number of the fans 5, so that each fan 5 corresponds to one exhaust port 102, and the fans 5 correspond to the exhaust ports 102 one by one. At present, dummy loads in the prior art are mainly centralized air exhaust, the air flow organization is greatly different from the actual air exhaust when the dummy loads are put into use, and the air volume value is far smaller than that of actual IT equipment. According to the air exhaust mode of the IT equipment, the proper number of the fans 5 and the proper arrangement positions of the fans 5 can be selected according to actual needs or the actual air exhaust mode of the IT equipment, the airflow organization of the IT equipment is simulated more truly, and objective and scientific test data are obtained. In addition, in the present application, the power of the fan 5 is extremely low, generally several watts, and the difference is more than several hundred times compared with the power consumption unit 301, which can be ignored during the test. In addition, while the fan 5 is connected, a rectifier 6 is generally connected to the load circuit to convert the ac power in the load circuit into dc power to ensure the rotation of the fan.
Optionally, on the basis of the above embodiment, the present solution further includes air volume sensors (not shown in the figure), the number of the air volume sensors is the same as the number of the fans 5, and the air volume sensors are correspondingly disposed near the fans 5 or the air outlets 102 and used for measuring the wind speed or the air volume of the fans 5. In an actual test, the operation number of the fans 5 can be adjusted at any time according to the test data of the air volume sensor so as to control the heat productivity, the airflow organization, the power environment information and the like of the IT equipment.
Optionally, the load testing device further comprises a plurality of power sensors (not shown) and a plurality of temperature sensors (not shown), which are integrated in the housing 1. The power sensor and the temperature sensor can be used for monitoring the power and the ambient temperature of the load testing device in real time so as to adjust the power and the ambient temperature at any time. The power sensor can be connected to the load circuit, or can be arranged as a separate module together with the temperature sensor. When the power sensor is connected into the load circuit, the power is also lower, and the influence on the power of the whole load circuit can be ignored.
As shown in fig. 2, optionally, the load circuit is provided with at least two power interfaces 202; the at least one power interface 202 is used for connecting the load testing apparatus according to any of the above aspects. Because the size of a single load testing device is small, and because of the limitation of the size, the setting number of the power consumption units 301 is limited, when an IT device with large size and high power is simulated for testing, a plurality of load testing devices are connected in parallel for use, on one hand, the size of a load can be simulated more really, on the other hand, the adjustable gears of the load testing devices can be increased, and the simulation can be carried out from the aspects of appearance, power value, power change and the like, so that the testing data is more real and has more reference value. During the test process, a plurality of load test devices can be connected through the power interface 202. One of the power interfaces 202 of the load testing devices at the beginning and end is used for accessing power, and the rest of the power interfaces 202 can be used for connecting other load testing devices in parallel.
