The design of power supply and distribution technology in the data center machine room has been developed and perfected continuously. UPS, intelligent PDU, monitoring management system, asset management and other products have become an indispensable part of the IDC machine room. The input of IDC data machine room users to intelligent PDU is also increasing, and the importance of intelligent PDU source management in the IDC machine room is important. In recent years, it has been particularly prominent.
PDU technical points:
Physical appearance:
(1) with black industrial physical appearance, integrated numerical LCD display screen. Switch on the button according to the button to switch different power parameters, such as current, voltage, power, electricity and so on.
(2) the measurement equipment of the redundant power supply route can be identified in different colors according to the requirement of the user, such as the red appearance of the A road and the blue appearance of the B road in order to reduce the human error operation.
(3) input / outlet connection cables are standard industrial connectors, supporting 1, 2 and 4 separate single-phase / three-phase circuits.
Technical requirements:
(1) monitoring: input device address, can be real-time access to all remote intelligent PDU power equipment input current state of work, the temperature of the micro environment of the equipment, humidity, current current and other information for every electrical equipment.
(2) communication interface: Standard RS485 interface, support network communication, WEB general user operation interface: support Firefox, Google Chrome and other kernel standard browser, IE6.0/8.0 and other common browsers, to realize PDU independent output plug - in monitoring, network parameter configuration;
(3) support independent plug in current monitoring, through the web page can complete the power supply of the next connected electrical equipment.
(4) support the IEC C13, C19, national standard and other socket mode;
(5) multi user support: allowing multiple users to access at the same time;
(6) single phase power input, the latest reliable anti trip protection.
The data center adopts the intelligent power divider PDU, which can monitor and control the real time of each IT device in the micro environment of the cabinet by remote monitoring and control. The monitoring mainly refers to the monitoring of voltage, current, power and electricity. Through intelligent PDU monitoring, equipment fault warning capability, switching time and autonomous processing capability can be improved. At the same time, through network monitoring, the running state of network devices can be monitored in real time, and the cost of manual maintenance can be reduced.
From the current use of mainstream intelligent PDU in the market, intelligent PDU needs to be improved in three aspects in order to improve the security, availability and popularity of intelligent PDU.
1, the convenience and effectiveness of the interface.
After the completion of the construction of the data center, the number of cabinet is huge and the number of PDU is distributed more. If the data is not read fast enough, the interface layer is complex, it is not convenient, it can not find the fault equipment in time and effectively. It causes the maintenance personnel to maintain the confusion, the interface is not clear and the error is not clear, so the maintenance engineer can not. Any abnormal alarm information at any time is traced at any time.
2. Hardware stability.
The more intelligent PDU functions, the stability is an index that the user attaches great importance to. The operation and maintenance personnel often use remote web landing control to have misoperation. It is necessary to consider the normal power supply and control of the electric power without affecting the internal environment. The abnormal state of the line, the artificial confirmation of the correct information, the rapid discharge of the normal operation of the fault recovery system in the shortest time, to achieve a point to control the global effect.
3, cost performance.
At present, the price of intelligent PDU products is relatively high, and it is necessary to improve the cost performance of intelligent PDU.
Intelligent PDU can be effectively solved. It provides remote management, fine service, low-cost, efficient, convenient, efficient and personalized VIP service for the IDC operation and maintenance system of the data center. Through the efficient network operation and maintenance system to provide high quality service for customers, it also greatly improves the network communication efficiency, reduces the unexpected losses caused by emergency events, and effectively reduces the operation and maintenance costs of the operators of IT.
