InRack and InRow Cooling for Data Center

Traditional data center, computer room, and server room cooling methods cool down an entire room with cold air from centralized units to one end of the room. This approach is acceptable when power densities are minimal with few hot spots in the room. However, room-oriented designs are affected by room constraints including ceiling height, room shape, obstructions above and below the floor, rack layout, Computer room air conditioning (CRAC) units' location, power distribution, etc.




CRAC units force chilled air into a data center and around the equipment. In most cases, cooling these vast volumes of air is very inefficient. Although a hot and cold aisle containment decreases the volume, it still results in a lot of excess cooling and costs of powering the CRACs. 

So why don't consider more selective data center cooling options which work together with your CRAC units or chill specific critical loads with high efficient ways but low energy cost?




Modern data centers adopt InRack and InRow coolers (IRCs), also known as close-coupled cooling systems, because they are tailor-made for high densities of hot-running IT equipment and tight energy budgets. These cooling strategies are inherently more efficient than standard CRAC systems because it ties into the IT equipment rather than sending cooled air into the room space. They may be mounted among the IT racks / cabinets or they may be mounted overhead or under the floor.


InRack Cooling




Dedicated racks, another low-effort retrofit, offer cooling isolation. The rack operates just like a standard data center rack, but it is sealed on all sides as a self-contained system. Cool air is forced up through the rack from the bottom, running over the equipment before exiting through the top to a hot plenum, where the heat is vented or recovered as necessary.




InRow Cooling




In-row cooling systems work within a row of standard server racks. The units are standard rack height, making them easy to match with the row and couple tightly to the IT equipment to ensure efficient cooling. Systems from APC by Schneider Electric, Liebert by Emerson Network Power, Rittal and others are engineered to take up the smallest footprint and offer high-density cooling. Ducting and baffles ensure that the cooling air gets where it needs to go.


    




Compared with the room-oriented architecture, the airflow paths are shorter and more clearly defined with the close-coupled cooling systems. Smaller fans can be used due to lower volumes of chilled air; energy costs are minimized; it is easier to target air onto high-density hot spots for preferential cooling; and business continuity improves, as the failure of any one single unit in the cooling environment only affects that rack or cabinet, as opposed to the total data center or the whole aisle containment. And, as the majority of these systems are modular, it is easy and cost-effective to build in degrees of resilience, leading to higher availability across the whole data center.

Data Center Design Consideration: Transformers and Harmonic Distortion


Data center managers and information technology (IT) engineers in today's critical facilities are in search of reliable and energy-efficient equipment with low total cost of ownership. But after equipment investments are made, it's important to pay attention to possible threats to the operational efficiency.


One threat that is often overlooked is harmonic currents, which can have a significant impact on electrical distribution systems and the facilities they feed. Wasted power and temperature fluctuations caused by these currents can prevent facilities from achieving maximum efficiency, so it's more important than ever for data center managers to evaluate their facilities and to take the time to develop a strategy mitigating harmonic current.


Harmonic Distortion


Harmonics are distortions of the normal electrical current waveform, generally transmitted by nonlinear loads. Switch-mode power supplies (SMPS), variable speed motors and drives, photocopiers, personal computers, laser printers, fax machines, battery chargers, and UPSs are examples of nonlinear loads. Single-phase nonlinear loads are prevalent in modern office buildings, while 3-phase nonlinear loads are common in factories and industrial plants.

A large portion of the nonlinear electrical loads in most electrical distribution systems comes from SMPS equipment. For example, all computer systems use SMPS that convert utility ac voltage to regulated low-voltage dc for internal electronics. These nonlinear power supplies draw current in high-amplitude short pulses that create significant distortion in the electrical current and voltage wave shape (Figure 1). This harmonic distortion, measured as total harmonic distortion (THD), travels back into the power source and can affect other equipment connected to the same source.


All periodic waves can be generated with sine waves of various frequencies. The Fourier theorem breaks down a periodic wave into its component frequencies.

Harmonic currents generated by nonlinear loads increase power-system heat losses and power bills for end users. These harmonic-related losses reduce system efficiency, cause apparatus overheating, and increase power and air conditioning costs. As the number of harmonics-producing loads has increased over the years, it has become increasingly necessary to address harmonics when making any additions or changes to a facility. 

Most power systems can accommodate a certain level of harmonic currents but will experience problems when harmonics become a significant percentage of the overall load. As these higher frequency harmonic currents flow through the power system, they can cause communication errors, overheating, and hardware damage. 


Reducing Harmonics


To determine if harmonic mitigation is necessary, facilities managers should conduct an assessment to precisely measure the harmonics affecting the data center and identify their origin. Solutions for harmonic mitigation vary in complexity and cost and can be deployed individually or in combination. The strategy that makes the most sense for a facility will vary based on the loads it supports, its budget, and the nature of the harmonic-related problems it is experiencing.


Solution 1 - K-rated Transformers in Power Distribution Components


A standard transformer is not designed for high harmonic currents produced by nonlinear loads. It will overheat and fail prematurely when connected to these loads. Therefore, when harmonics were first introduced into electrical systems at levels that showed detrimental effects (circa 1980), the industry responded by developing the K-rated transformer. K-rated transformers are not used to eliminate harmonics, but to manage the heat generated by harmonic currents.




K factor ratings range between 1 and 50. A standard transformer designed for linear loads is designated with a K-factor of 1. The higher the K-factor, the more heat from harmonic currents the transformer is able to withstand. When selecting a K rating, managers should consider the trade-offs between size, efficiency, and heat tolerance. For example, transformers with higher K factors are typically larger than those with lower K factors. The table shows appropriate K ratings to use for different percentages of nonlinear current in the electrical system.





Power distribution units (PDUs) with a K 13-rated transformer are readily available to efficiently handle harmonic currents. Units with K 20 transformers are common, but are typically overkill for most modern data centers.




Units with K 20 transformers are common, but are typically overkill for most modern data centers. The K-rated, dry-type transformer is widely used in electrical environments - either in a PDU or as a stand-alone unit. However, recent advances in transformer design are changing the way facilities managers reduce voltage distortion and power loss caused by harmonic currents. 


Solution 2 - Harmonic Mitigating Transformer


A harmonic-mitigating transformer (HMT) is designed to handle the nonlinear loads of today's electrical infrastructures. This transformer uses electromagnetic mitigation to deal specifically with the triplen (3rd, 9th, 15th, and so on) harmonics. Secondary windings of the transformer are arranged to cancel zero sequence fluxes and eliminate primary winding circulating currents. This transformer also addresses the 5th and 7th harmonics by using phase shifting.






Using these two electromagnetic techniques, an HMT allows loads to operate as they were intended, while minimizing the energy loss and distortion caused by harmonics. Most HMTs exceed NEMA TP-1 efficiency standards, even when tested with 100% nonlinear loads. Wherever a K-rated transformer is specified, an equivalent HMT is a direct substitute.



Solution 3 - Harmonic Mitigating UPS


Much like an active filter, harmonic-mitigating UPS eliminates harmonic distortion by inserting equal and opposite current into the line. They also compensate for reactive power from low power-factor loads and balance loads across 3-phase systems to avoid stranded capacity, as well as to provide clean and continuous power during utility outages or in response to electrical disturbances.






Going Further


Data center managers are increasingly deploying UPSs with energy-saver operating modes to boost efficiency and lower power costs. Recently, harmonic-mitigating UPSs capable of keeping distortion within predetermined and adjustable limits, correcting power factor, and balancing loads while in energy-saver mode have begun to reach the market.

These new systems typically remain within 1% of energy-saver levels while performing these functions, a significant improvement over past technologies. The harmonic mitigation technology in the latest energy-saver UPSs is a built-in feature that requires no additional footprint, saving valuable data center floor space and reducing installation and maintenance costs.

Harmonics continue to be costly for data centers, preventing data center managers and engineers from achieving maximum reliability and efficiency. Fortunately, the latest enhancements in UPS technology offer next-generation harmonic-mitigation capabilities. Though not always required, such systems enable data centers to achieve the highest efficiency possible by actively correcting for harmonic currents as they occur.

Apple Builds its first Data Center in Guizhou, China

Apple Inc on Wednesday (12 Jul 2017) announced that they are going to build its first data center in China, in partnership with a local internet services company, to comply with tougher cyber-security laws introduced last month.




The critical facilities will set up in Guizhou with the help of Guizhou-Cloud Big Data Industry Co. Ltd., and represents a portion of Apple's planned $1 billion investment into the province.

"The addition of this data center will allow us to improve the speed and reliability of our products and services while also complying with newly passed regulations," Apple said in a prepared statement. "These regulations require cloud services be operated by Chinese companies so we're partnering with GCBD to offer iCloud."

In April, China also announced a law requiring businesses transferring over 1,000 gigabytes of data outside China to undergo yearly security reviews, with potential blocks on exporting economic, technological and scientific data.

Apple was quick to note that its data protection protocols, viewed by some as the industry standard, will not be impacted by China's laws. The authorities also said the law is not designed to put foreign firms at a disadvantage and is drafted in reaction to the threat of cyber attacks and terrorism.

"No backdoors will be created into any of our systems," Apple said. The comment seemingly addresses fears that Chinese government agencies might use the cybersecurity law as an invitation to engage in snooping activities.


Earlier this week, Apple said it planned to open a new data center in Denmark. An earlier center in the country, announced in 2015, will come online this year.

Other foreign firms that oversee cloud businesses, including Amazon.com Inc and Microsoft Corp, already have data centers in China.
