Description

Technical Field

[0001] The present invention belongs to the technical field of the U-position control system of a data center, and specifically relates to a large data center equipment racking system and method based on U-position control. Background Art

[0002] The arrangement position of equipment racking in a large data center has always been an important issue for the safe and stable operation of the data center. Moreover, the racking of equipment is carried out step by step according to business and leasing situations, rather than installing all equipment in all cabinets at one time, resulting in the specific installation positions of newly racked equipment and already racked equipment. The traditional principle of equipment racking is based on position priority, first come first served, and sequential installation. This has the advantages of compact equipment installation and convenient centralized management. However, if the power arrangement of equipment is unbalanced, the following problems are likely to occur: 1) It causes unbalanced three-phase loads in the distribution cabinet at the head of the row, resulting in excessive neutral line current, causing power loss in the neutral line of the power grid, increasing the power loss of the power grid. In places with high requirements for the zero-ground voltage of the data center, it is very easy to cause the zero-ground voltage to exceed the limit, affecting the normal operation of electronic products; 2) The unbalanced three-phase load on the power supply side of the transformer is likely to cause a decrease in the overload capacity of the transformer; 3) The unbalanced three-phase load causes excessive neutral line current, and the wire may burn out. Although the cross-sectional area of the neutral line conductor is generally 50% of the cross-sectional area of the phase conductor, in actual application, there will inevitably be problems such as a relatively small cross-sectional area of the neutral line conductor and poor joint quality, resulting in an increase in resistance and thus burning out the neutral line.

[0003] Therefore, aiming at the situation of step-by-step racking of equipment in a large data center, it is urgent to propose a racking method that takes into account current measurement, U-position size, and optimal load balance, so as to truly achieve the basic load balance of data center equipment. Summary of the Invention

[0004] The purpose of the present invention is to provide a large data center equipment racking system and method based on U-position control, which improves the rationality of distributed racking of large data center equipment, makes the overall load more balanced, and reduces the loss of cables.

[0005] The present invention is realized by the following technical solutions:

[0006] A large data center equipment racking system based on U-position control includes several rows of cabinets installed in a computer room. An RTU data collector is installed at the bottom 1U position of the distribution cabinet at the head of each row of cabinets. The RTU data collector is connected to an access switch installed in any one of the cabinets through a twisted pair, and the access switch is connected to a data server installed in a monitoring room through an optical fiber;

[0007] The monitoring room is also equipped with a handheld scanning server, which is wirelessly connected to the data server and is wirelessly connected to a scanner. The scanner is used to scan the QR code of the device to be put on the shelf and transmit the identified information to the handheld scanning server. The handheld scanning server is used to parse the information uploaded by the scanner to obtain the information of the device to be put on the shelf, and transmit the information of the device to be put on the shelf to the data server;

[0008] The data server is used to store information of devices that have been put on the shelves, and allocate the best shelf position for the devices to be put on the shelves according to the information of the devices to be put on the shelves transmitted by the handheld scanning server.

[0009] Furthermore, the access switch is installed at the 6U position in the C4 cabinet in the C column cabinet.

[0010] Furthermore, the twisted pair cable is a Category 6 network cable.

[0011] Furthermore, the RTU data collector is connected to the access switch via a Category 6 network cable along the weak current bridge of the computer room.

[0012] A method for mounting equipment in a large data center based on U-position control includes the following steps:

[0013] Step 1: Create a location information table for each cabinet in the data server, fill in the information of the racked equipment in the table, and record the cabinet information;

[0014] Step 2: Install a large data center equipment racking system based on U-position control;

[0015] Step 3: Every 5 minutes, the RTU data collector collects the current I of phase A, phase B, phase C and neutral line of each cabinet in its row. A ,I B ,I C and I n ;

[0016] Step 4: Calculate the three-phase current difference I first, expressed as:

[0017] I=I max -I min

[0018] Where, I max For I A ,I B and I C The maximum current in min For I A ,I B and I C The minimum current in

[0019] Calculate the equipment power P that each cabinet needs to balance again c , which is expressed as:

[0020] P c = I × 0.22 × 0.9

[0021] Every 5 minutes, sum up all the P c cumulatively and calculate the average value, and record P c in the location information table;

[0022] Then use the total rated power P 总 of the equipment that can be installed on each cabinet to subtract the rated power of the installed equipment, and obtain the remaining installation power P l of each cabinet. Record P l in the table, and record the corresponding voltage of I min in the table;

[0023] Step 5: Use a barcode scanner to scan the QR code of the equipment to be installed, and obtain the rated power P e of the equipment to be installed. Query the equipment power P c that each cabinet needs to balance. If P e < P c , when P = |P e - P c | is the smallest, select the cabinet corresponding to P c , and query whether the remaining U positions in this cabinet are greater than the U + 1 positions of the equipment to be installed. If so, this cabinet is the best cabinet, and the data server recommends the optimal installation position for the equipment to be installed according to the equipment U + 1 position; if not, select the cabinet corresponding to the second smallest P, and query whether the remaining U positions in this cabinet are greater than the U + 1 positions of the equipment to be installed; and so on, traverse all cabinets, recommend the optimal installation position for all equipment to be installed, and provide the power phase for the equipment according to the recorded voltage phase of I c corresponding to it; min If P

[0024] > P e > P c , traverse the remaining installation power P l of each cabinet, and select the cabinet corresponding to P l > P c and |P l - P c | = P is the smallest, and query whether the remaining U positions of this cabinet are greater than the U + 1 positions required by the equipment. If so, this cabinet is the best cabinet, and recommend the installation position for the equipment to be installed according to the U + 1 of the equipment; if not, select the cabinet corresponding to the second smallest P; and so on, traverse all cabinets, recommend the optimal installation position for all equipment to be installed, and provide the power phase for the equipment according to the recorded voltage phase of I minThe corresponding voltage phase is used as the phase for power supply to the equipment;

[0025] Step 6: If P c > 0.01×P 总 , label this P c The A-phase, B-phase, and C-phase of the corresponding equipment are unreasonably arranged. Locate the phases corresponding to I max and I min in this cabinet, and search for all equipment information in the voltage phase corresponding to I max to determine whether the following conditions are simultaneously met:

[0026] I 设备 = P 设备 / (220*0.9)

[0027] ((I max - I 设备 ) - (I min + I 设备 )) × 0.22 × 0.9 < 0.01×P 总

[0028] where P 设备 is the rated power of the equipment, I 设备 is the rated current of the equipment, and P 总 is the total rated power of the equipment that can be installed on each cabinet;

[0029] If the conditions are met, replace the power supply circuit of the equipment in the voltage phase corresponding to I max with the power supply circuit corresponding to I min to supply power; otherwise, select the equipment with the largest rated power from all the equipment information in the voltage phase corresponding to I max as the new equipment, and find the optimal installation position for it according to Step 5;

[0030] Step 7: Install the new equipment on the shelf according to the recommended optimal installation position.

[0031] Furthermore, it is characterized in that the specific process of Step 1 is as follows: Create a location information table for each cabinet in the data server. If equipment has been installed on the U-position of the cabinet, fill in the information of the installed equipment at the corresponding position in the table. If no equipment is installed on the U-position of the cabinet, fill in blank. At the same time, record the average current, voltage, power, and the equipment power to be balanced of the cabinet in the table.

[0032] Furthermore, the total rated power P 总 of the equipment that can be installed on each cabinet in Step 4 and Step 6 is 8000W.

[0033] Furthermore, for all P cThe number of cumulative summations is not greater than 20 times.

[0034] The present invention collects the three-phase current measurements of each cabinet where the RTU data collector is located, calculates the equipment power to be balanced and the remaining installation power of each cabinet, and obtains the rated power by scanning the QR code of the equipment to be installed on the shelf. First, compare the equipment power to be balanced with the rated power and check whether the remaining U positions of this cabinet are greater than the U + 1 positions required by the equipment. Then, compare the remaining installation power with the equipment power to be balanced and check whether the remaining U positions of this cabinet are greater than the U + 1 positions required by the equipment, so as to traverse all cabinets, recommend the optimal installation position, and take into account the size of the remaining U positions in the cabinet to recommend the optimal installation position for the equipment to be installed on the shelf; at the same time, by monitoring the load of the data center, shift the equipment in the cabinets with long-term load imbalance and recommend the optimal position for it; in short, the present invention can balance the charge of each cabinet to the greatest extent, effectively prevent load imbalance caused by inappropriate equipment installation positions, reduce the situation that precision electronic equipment cannot work properly due to excessive zero-line current and excessive zero-ground voltage, and also reduce the zero-line current in the entire power supply and distribution system, and can effectively reduce zero-line heating and the occurrence of fire accidents.

[0039] The following further elaborates on the present invention in detail in conjunction with specific embodiments, which is an explanation rather than a limitation of the present invention.

[0040] Such as Figure 2 and Figure 3As shown in the figure, a large data center equipment racking system based on U-bit control includes 17 columns of cabinets 3 installed in the computer room, named column A to column Q in sequence. Each column of cabinets 3 includes a head cabinet 1 and 18 cabinets arranged next to the head cabinet 1, named A1 to A18 in sequence. RTU data collectors 2 are installed at the 1U positions at the bottom of each head cabinet 1. An access switch 4 is installed at the 6U position in the C4 cabinet of column C of the cabinets 3. The RTU data collectors 2 are connected to the access switch 4 through twisted pairs 8, and the access switch 4 is connected to a data server 5 installed in the monitoring room through optical fibers 7;

[0041] Inside the monitoring room, a handheld scanning server 6 is also equipped. The handheld scanning server 6 is wirelessly connected to the data server 5, and the handheld scanning server 6 is wirelessly connected to a scanning gun. The scanning gun is used to scan the QR code of the device to be racked and transmit the recognized information to the handheld scanning server 6. The handheld scanning server 6 is used to parse the information uploaded by the scanning gun to obtain the information of the device to be racked, including the size, type, rated power, and code of the device to be racked, and transmit the information of the device to be racked to the data server 5;

[0042] The data server 5 is used to store the information of the racked devices, and allocate the optimal racking position for the device to be racked according to the information of the device to be racked transmitted by the handheld scanning server 6, so as to optimize the load balance of the cabinets.

[0043] Preferably, the twisted pair 8 is a category 6 network cable, and the RTU data collector 2 is connected to the access switch 4 along the weak current bridge in the computer room through the category 6 network cable.

[0044] As Figure 1 shown, a large data center equipment racking method based on U-bit control includes the following steps:

[0045] Step 1: Create a position information table for each cabinet 3 in the data server 5, fill in the information of the racked devices at the corresponding positions in the table. If there is no racked device at the U-bit of the cabinet, fill in blank, and record the average current, voltage, power, and the power of the device to be balanced of the cabinet 3. Generally, each cabinet 3 has 42 U-bits. Set the remaining number of U-bits that can install devices in each cabinet 3 as U 剩 Then U 剩 = 42 - 1 - the number of U-bits of the devices already racked in the cabinet;

[0046] Step 2: Install as Figure 1The described large data center equipment racking system based on U-bit control has the following process: An RTU data acquisition device 2 is installed at the 1U position at the bottom of each header cabinet 2 in the computer room. An access switch 4 is installed at the 6U position in cabinet C4 among the C-column cabinets. A data server 5 and a handheld scanning server 6 are installed in the monitoring room. All RTU data acquisition devices 2 are arranged along the weak current cable tray in the computer room using Category 6 network cables and are connected to the access switch 4. The access switch 4 is connected to the data server 5 in the monitoring room using an optical fiber 7, forming a single-layer network with the data server 5 and the handheld scanning server 6. The handheld scanning server 6 is equipped with a barcode scanner for scanning the QR code of the racked equipment, which is wirelessly connected to the handheld scanning server 6;

[0047] Step 3: Every 5 minutes, the RTU data acquisition device 2 collects the currents IA, IB, IC, and the neutral line current I of the 17 cabinets 3 in its column A 、I B 、I C and I n ;

[0048] Step 4: Calculate the equipment power that needs to be balanced for each cabinet 3 and the remaining power available for installing equipment in each cabinet 3. The specific process is as follows:

[0049] Step 4.1: First, calculate the three-phase current difference I, expressed as:

[0050] I = IA max - IB min

[0051] where IA max is the maximum current among IA A , IB B and IC C , and IB min is the minimum current among IA A , IB B and IC C ;

[0052] Then calculate the equipment power P c that needs to be balanced for each cabinet 3, expressed as:

[0053] P c = I × 0.22 × 0.9

[0054] Step 4.2: Every 5 minutes, sum up all the P c values and calculate the average value. The maximum number of cumulative times is 20 times, and record the P c value in the location information table;

[0055] Step 4.3: Using the total rated power P 总Subtract the rated power of the installed devices to obtain the remaining installation power P of each cabinet 3 l , record P l in a table, and record the corresponding voltage phase of I min in the table; Usually, the total rated power P 总 of the installable devices in each cabinet 3 is 8000W, then the remaining installation power P l of each cabinet 3 is expressed as:

[0056] P l = (8000W - the rated power of the devices already installed in each cabinet

[0057] Step 5. Find the optimal position for the devices to be installed. The specific process is as follows: Use a barcode scanner to scan the QR code of the device to be installed to obtain the rated power P e of the device to be installed, and query the device power P c that needs to be balanced in each cabinet 3;

[0058] If P e < P c , when P = |P e - P c | is the smallest, the corresponding cabinet 3 of P c is selected, and check whether the remaining U positions in this cabinet 3 are greater than the U + 1 positions of the device to be installed. If so, this cabinet 3 is the best cabinet, and the data server 5 recommends the optimal installation position for the device to be installed according to the U + 1 position of the device; If not, select the cabinet 3 corresponding to the second smallest P. By analogy, traverse all cabinet 3s to recommend the optimal installation position for all devices to be installed, and provide the power supply phase for the device according to the recorded voltage phase corresponding to I c ; min corresponding voltage phase;

[0059] If P e > P c , traverse the remaining installation power P l of each cabinet 3, and take P l > P c and |P l - P c | = P corresponding to the smallest cabinet 3, and check whether the remaining U positions in this cabinet 3 are greater than the U + 1 positions required by the device. If so, this cabinet is the best cabinet, and recommend the installation position for the device to be installed according to the U + 1 of the device; If not, take the cabinet 3 corresponding to the second smallest P; By analogy, traverse all cabinet 3s to recommend the optimal installation position for all devices to be installed, and use the voltage phase corresponding to the recorded I min as the power supply phase for the device;

[0060] Step 6. Optimize the cabinets with long-term load imbalance in cabinet 3. The specific process is as follows: If P c >0.01×P 总 , mark the A-phase, B-phase, and C-phase of the equipment corresponding to this P c as unreasonable arrangements. Locate the phases corresponding to I max and I min in this cabinet, and search for all equipment information in the voltage phase corresponding to I max in the table to determine whether the following conditions are simultaneously met:

[0061] I 设备 =P 设备 / (220*0.9)

[0062] ((I max -I 设备 )-(I min +I 设备 ))×0.22×0.9<0.01×P 总

[0063] where P 设备 is the rated power of the equipment, I 设备 is the rated current of the equipment, and P 总 is the total rated power of the equipment that can be installed on each cabinet 3;

[0064] If the conditions are met, replace the power supply circuit of the equipment in the voltage phase corresponding to I max with the power supply circuit corresponding to I min ; otherwise, select the equipment with the maximum rated power from all the equipment information in the voltage phase corresponding to I max as the new equipment, and find the optimal installation position for it according to Step 5;

[0065] Step 7. Install the new equipment on the shelf according to the recommended optimal installation position.
