一. How does the PDU help the computer room survive the summer?
The use of smart PDU can help the computer room to survive the summer safely. Smart PDU is also called remote control power socket, which is a product to meet the micro-environment monitoring application of the computer room. On the basis of the traditional computer room power supply PDU, the external temperature and humidity monitoring of current and voltage is added, and the power interface can be remotely and independently controlled.
1. Compared with the basic PDU, the smart PDU has irreplaceable advantages:
The basic PDU can only provide basic power distribution functions; while the intelligent PDU can not only provide current, voltage and protection, but also provide various advanced functions, such as power metering, environmental monitoring and remote port remote control, and control the entire data center. Effective and reliable operation monitoring management can not only help reduce the operating cost of the data center, improve the uptime, reliability, improve the mean time to repair (MTTR) of equipment, make the power usage of the data center more efficient, but also realize the existing data center Capacity and asset management.
2. The powerful mechanism design of intelligent PDU can withstand the harshest external conditions:
High-grade input cable connectors, strain relief and durable, more powerful than common low-cost clamp-on mechanisms, solid chassis sides, no perforations or vents, prevent particles from contacting internal conductors, no short circuits, and Thermally safe; small footprint with optimal access characteristics, airflow characteristics, and easy physical installation; tolerates maximum ambient temperature (60C/140F) for safe operation even with highest placement density and continuous loading ;The output socket wiring phase is designed alternately, which is convenient for cable bundling and has higher load balancing efficiency.
3. With the help of powerful monitoring and management functions, ensure the safety and efficiency of summer operation and maintenance:
Outlet port output level power monitoring detects actual redundancy, implements the most effective load balancing, and provides detailed status of each power supply of the server; Gigabit Ethernet port, and has auxiliary network connection as backup to ensure monitoring reliability and realize Simultaneous insight sharing of IT network and building management, efficient and intuitive Power IQ management interface, real-time inspection of equipment energy consumption, hot spots and PUE, and balance of thermal and power loads.
二. How to choose a PDU power supply?
(1) Choose the product that suits you according to your specific situation;
(2) Choose products from regular manufacturers (of course, some manufacturers may also be regular manufacturers, but PDU may not be their dominant product, so you should be careful when choosing. Although a veterinarian is also a doctor, you can’t think that he is also a famous doctor as long as he is a doctor. Everyone can’t see a doctor. find him);
(3) The country has relevant quality inspection and certification for various products. When choosing a PDU product, you must first look at the qualifications of the manufacturer, and then look at the quality certification of the product. It is safer to choose regular products;
(4) After summarizing the above, understand the after-sales service of related products (no matter how good the product is, no one can guarantee that it will not be broken, so after-sales service is also a key issue, and remember that after-sales service cannot just be said by mouth, it is recommended to implement it Take root, pay it with words)
三. Focus on PDU in different periods of computer room construction
PDU selection method:
(1) The circuit power of the distribution branch of the top cabinet + safety margin = the sum of the power of the PDU on this line;
(2) The number of devices in a cabinet + safety margin = the number of jacks of all PDUs in the cabinet. If there are dual redundant lines, the number of PDUs should be doubled with the parameter.
(3) Disperse high-power equipment in different PDUs as much as possible to balance the current of each phase;
(4) Customize the hole type of the PDU based on the equipment plug whose power cord cannot be separated. Once the plug of the device whose power cord can be separated is not compatible, it can be solved by replacing the power cord;
(5) If the equipment density in the cabinet is high, it is advisable to install the PDU vertically with multiple jacks. If the equipment density in the cabinet is low, it is better to install the PDU horizontally with fewer jacks.
1. Installation and commissioning period:
(1) The power of the power distribution socket in front of the cabinet should match the circuit power of the distribution branch of the top cabinet and the power of the PDU, otherwise the power index will be reduced;
(2) The installation U position of the PDU should be reserved for the horizontal installation of the PDU. When the vertical installation of the PDU is installed in the cabinet, the position of the lateral baffle plate on the side of the cabinet should be aligned with the installation size of the PDU;
(3) The double-round European standard plug cannot be directly inserted into the universal hole, so that the grounding will be suspended, which is very dangerous. The correct way is to replace the plug or use the embedded European standard jack, and then use the special conversion line for converting the European standard to the national standard.
2. Operation period:
(1) Pay attention to the temperature rise index, that is, the temperature change between the equipment plug and the PDU jack;
(2) If there is a PDU with remote monitoring, you can pay attention to the current change of the PDU to judge whether the equipment is working normally;
(3) Make full use of the cable management device of the PDU to break down the outward breaking force of the equipment plug on the jack.
3. Points for attention in custom selection
(1) Customized PDU process: how much is the total current (calculate about 50% redundancy based on the sum of output device power);
(2) Input part: the length of the cable (generally standard 2-3 meters is enough);
(3) The wire diameter is determined by the total current, and the plug at the power-taking terminal is determined by the total current and the front-end power supply environment; the number of output sockets is several for each type of socket, and the domestic universal interface is mostly used;
(4) Protection function selection (lightning protection, overload, digital display, power indication, dual power automatic switching, remote monitoring, etc.);
(5) Installation method selection (horizontal installation or vertical installation)
(6) Product material: steel plate material or profile shell.
