Abstract ： The intelligent products needed by modern data centers not only need to meet the market requirements , And beyond the user's confidence in its reliability , Ability and quality expectations .

recently , A power supply company elaborated the promotion of intelligent power supply PDU Four development trends of the market . He is developing and selling and managing rack power distribution , Uninterruptible power supply , Energy storage and DCIM There are solutions 20 Years of experience . He analyzed IHS Power distribution unit recommended by consulting company （PDU） Application and development of , And highlights some drivers PDU Characteristics of industry market demand .
　　
　　 The intelligent products needed by modern data centers not only need to meet the market requirements , And beyond the user's confidence in its reliability , Ability and quality expectations .
　　
　　 These reflect what people see in the market for virtualization , Equipment integration （ Higher rack power density ） And market demand for more efficient computing . for example , Although a few years ago, the average power density of the cabinet supported 3-4kW, But now people think this is actually a low power density environment . Today's cabinet power has reached 9-15 kw , And in some cases even higher , It's not uncommon .
　　
　　IHS The consulting firm pointed out that , Users will see products with more intelligent functions in the market , Such as remote control and switching , Enterprise reporting and monitoring functions . therefore ,IHS expect 2016 In the world PDU Annual market growth 5.6％, The market size is close to 10 Billion dollars .
　　

The following is the driver PDU Four characteristics of market growth ：
　　
　　1. Demand for high power ratings
　　
　　 The high-density environment of the data center needs to come from PDU More input power . Extend the three-phase connection to the rack , Can be improved through each PDU The amount of electricity provided , So as to improve the power density of the rack . It also simplifies the load balancing process of the three input stages into the data center , Improved work efficiency , And by increasing the voltage , Make the current of the circuit lower , Therefore, thinner conductors can be used to provide more power .
　　
　　 therefore , For new market opportunities , It is important to consider deploying a three-phase system PDU, It can receive 415V The input voltage of , Compared with the traditional voltage is 208V Our products are more efficient and energy-saving .
　　
　　2. Switch to smarter products
　　
　　 As people's demand for availability continues to grow , Data center operators need to continuously monitor power usage throughout the power chain , Including rack PDU. Most intelligent PDU The power level of input and branch circuits is provided through threshold and notification functions , voltage , electric current , Power and energy monitoring . For visibility , Proactive steps are needed to reduce IT Energy consumption of equipment . Besides , One growing trend is to invest in intelligence PDU, This provides monitoring capability to the export level .
　　
　　 And deploying intelligence PDU One of the biggest challenges associated with this is all... In the data center PDU Additional cost of . Using security chip technology PDU This can be done through a single with failover IP Address merge up to 32 individual PDU, And significantly reduce these costs .
　　
　　3. Requirements for environment and security functions
　　
　　 The temperature of the data center rises , The efficiency of the cooling system is improved , And reduce the cooling cost , But its exhaust temperature is also rising . In order to prevent equipment failure caused by overheating , High ambient temperature ratings must be deployed PDU.
　　
　　 On the safety side , Industry manufacturers are committed to providing support with integrated security and various user authentication methods （ Include HTTP/HTTPS,SNMPv1/v2/v3,RADIUS and LDAP Integration and secure socket layer （SSL）） Network protocol solution . At the physical level , The locking function can prevent accidental disconnection from the socket , Click directly in place , And can't move , Unplug during addition and change .
　　
　　4. Power supply is required , Capacity planning and remote control
　　
　　 By measuring the power supply power at the rack or equipment level , The operator can identify underutilized or over utilized capacity . With special switching function PDU Each socket is also allowed to have remote socket control （ON/OFF） function , So that unused sockets can be closed when not in use . Besides , for example , By integrating intelligence PDU Integration with centralized power management software solutions , Operators can track power usage over a period of time , And know its activity cost .
　　
　　 Conclusion
　　
　　 The intelligent products needed by modern data centers not only meet the basic market requirements , And beyond what people think of its reliability , Ability and quality expectations .AshishMoondra Recently wrote a white paper , Discuss the deployment of smart devices in high power density environments PDU Key considerations , Describe the important role played by each function of the power supply system .
