The intelligent PDU can help the computer room to survive the summer. The intelligent PDU also says that the remote control of power outlet is to meet the requirements of the microenvironment monitoring application of the computer room.On the basis of PDU, the external temperature and humidity monitoring of current voltage is added.
1. Compared with basic PDU, intelligent PDU has irreplaceable advantages:
Basic PDU can only provide basic power distribution function.And intelligent PDU in addition to provide current, voltage and protection, also can provide various advanced features, such as electric power metering, environmental monitoring and remote port control, implements effective and reliable operation for the entire data center monitoring and management, can help reduce the operating costs of data center, improve the uptime, reliability, improve equipment mean time to repair resolution (MTTR) for customer-impacting events caused, be more effective in their data center electricity use, also can realize the existing data center capacity and asset management.
2. Powerful mechanism design of intelligent PDU, which can withstand the toughest external conditions:
Senior input wire connection, stress release and durable, compared with the general low cost type organization, more powerful, chassis side firmly, without punching or vents, prevent particles contact internal conductors, there will be no short circuit, and the heat radiation safety;Small space footprint, with the best access characteristics, airflow characteristics, easy to install physical;The maximum ambient temperature (60C/140F) can be tolerated, and safe operation can be realized even under the condition of the highest layout density and continuous loading.Output socket connection phase alternating design, easy to tie cable, higher load balancing efficiency.
3. Ensure the safety and efficiency of summer operation and maintenance with powerful monitoring and management functions:
The output power monitor of socket port detects the actual redundancy, implements the most effective load balancing, and provides the detailed status of each power supply of the server.Gigabit Ethernet port, and has the auxiliary network connection as a backup, to ensure that monitoring and reliability, and implement IT network and the construction management of insight to share at the same time, high efficiency Power IQ management interface intuitive type, can be to check the equipment energy consumption, hot and PUE, carried out on the heat and Power load balancing.
How to select PDU power supply?
(1) select suitable products according to their specific conditions;
(2) select the product of normal manufacturer (some manufacturers may also be a normal manufacturer, of course, but pdus may not be the advantage products, when the choice should be discreet, although a vet is a doctor, but I can't think he is also a famous doctor, as long as a doctor you see a doctor can't find him);
(3) the state has relevant quality inspection and certification for all kinds of products. When choosing PDU products, we should first look at the qualifications of the manufacturers and then the quality certification of the products.
(4) integrated above, and then understand related products after-sales service (it is a good product, no one can guarantee there is no bad, so the after-sales service is also a key issue, and after-sales service not only by mouth, suggested that the ground to take root, by words)
1. The attention paid to PDU in different periods of machine room construction
Bidding planning phase selection: a lot of room and there is no the PDU with UPS as single row, column head cabinet, cabinets and other equipment, PDU parameters also is very not clear, even some just indicate the power strip, this will cause a lot of late work problems: namely not matching with other equipment, non-standard distribution, shortage of budget, etc., both sides of this phenomenon is the main reason for bidding is not clear how the PDU labeling requirements?Here's a simple way to do it:
(1) power of the circuit of the distribution branch of the header cabinet + safety margin = the total power of PDU on this line;
(2) the number of equipment + safety margin in a cabinet = the number of holes in all PDU in the cabinet. If there are two redundant lines, the number of PDU should be doubled with the same parameters.
(3) distribute the high-power equipment in different PDU as far as possible to balance the current of each phase;
(4) the PDU's pore type is customized based on the device plug that cannot be separated from the power cord. If the device plug that can be separated from the power cord is not compatible, the power cord can be replaced to solve the problem.
Cabinet inside the devices (5), high density PDU it is advisable to choose multiple tap vertical loading, low density inside the cabinet equipment, PDU it is advisable to choose less jack lateral finally to quote PDU separate budget in order to avoid a serious shortage of budget.
2. Installation and commissioning period:
(1) the power of the power distribution socket in front of the cabinet should be matched with the power of the circuit of the distribution branch of the column header cabinet and the power of PDU, otherwise, the power index of use will be reduced;
(2) when installing PDU horizontally, the installation U of PDU should be reserved. When installing PDU vertically, the position of the lateral rail plate on the side of the cabinet should be in line with the installation size of PDU.
(3) the double-round European standard plug cannot be directly inserted into the universal hole, so the grounding will be suspended and very dangerous.The correct method is to replace the plug or use the embedded European standard jack, no more using the European standard to convert the national standard's special conversion line.
3. Operation period:
(1) pay attention to the temperature rise index, that is, the temperature change of the device plug and PDU jack;
(2) if there is a PDU with remote monitoring, the current change of PDU can be observed to determine whether the equipment is working normally.
(3) make full use of PDU's wiring device to decompose the external release force of the device plug on the socket.
4. In summary: in fact, the following is all that matters when selecting customized models:
(1) customized PDU process: what is the total current (about 50% redundancy according to the total power of the output device);
(2) input part: the length of the cable (usually 2-3 meters is enough);
(3) the wire diameter is determined by the total current, and the power supply environment of the front end is determined by the total current and the power supply environment of the front end.The number of output sockets, a few for each socket, the domestic multipurpose interface used more;
(4) protection function selection (lightning protection, overload, digital display, power indicator, automatic switching of dual power supply, remote monitoring, etc.);
(5) installation method selection (horizontal or vertical installation)
(6) product material: steel plate or profile shell.
