You can’t talk about 5G, data networks or the “Internet of Things” (IoT) without adding a new buzzword to the conversation: densification. But it’s more than the latest trend; it comes with real, relevant value. As network providers work overtime to keep pace with increased demand on bandwidth, densification is a solution that can achieve efficiency and better customer experience.
Densification in a word (or two) is more capacity, specifically within the same area or footprint. Think about the last concert or sporting event you attended, and the thousands, even tens of thousands, of people using their mobile devices all at once. The saturation of users clogs the network and all of a sudden you can’t upload that perfect selfie or favorite video clip. The same concept happens with data networks. And densification is the proverbial Drayno.
According to Ericsson’s Mobility Report, global mobile data traffic is expected to rise at a compound annual growth rate of 42% from 2017 to 2023. The report states, “in response to increasing demands, the mobile industry is focusing on optimizing the spectral efficiency of LTE in existing frequency bands using new advanced functionalities, such as Multiple Input Multiple Output (MIMO) and carrier aggregation. To solve capacity needs long-term, most countries are expected to make additional spectrum available under new national 5G regulatory regimes.”
An article in Enterprise Insights says that the “continuous increase in traffic within mobile broadband systems and continuous increase in required and requested data rates for end users will impact how cellular networks are deployed in the future, according to Telecom Insights.”
Power and cooling demands are increasing exponentially, and it’s an advantage—environmentally and for businesses—if companies can handle a lot more power in the same space. High-density data centers help drive environmental and operational cost efficiencies. The more network, compute, storage and service you can deliver per work cell cost, the better it is for your pocketbook and the planet.
What is the future of densification?
There are three major trends driving an increase in data center density:
1) Doing more within the same footprint. The opportunity for businesses with large infrastructures and deployments to gain significant efficiencies and competitiveness is a very real benefit. For example, the difference between low density (measured on average at 6KW/rack) versus high-density (measured at 12KW) data centers is enough of a swing to experience real cost savings.
2) 5G network creation and its requirements of high system capacity and high per-user data rates. This will require a densification of the radio access network or the deployment of additional network nodes. As 5G becomes more defined and eventually standardized, densification grows increasingly important for ultra-dense network configurations, especially for metro areas heavy with users, such as New York City or San Francisco.
3) Power and cooling availability and efficiency. Driving high-density data center efficiencies and lowering costs is a huge competitive advantage both in the short and long-term. Aligned’s cooling technology can cool efficiently to 50 kW per rack for real cost savings in both energy and real estate.
While the future of data center densification is important to do more with less space, creating efficiencies and improved service, densification is also important because, well, we love our smartphones. And that’s not changing anytime soon.
Aligned’s technologies can future-proof your data centers. One of our data centers in Dallas, Phoenix, Arizona or Salt Lake City, Utah, enables clients to take advantage of an industry-leading 1.15 PUE and run 1-50 kW per rack and mix densities within the same row.

Learn to Save Water or Your Data Center May Tank
757 million liters. That’s about 2,000 Olympic-sized swimming pools–all full of crystal-clear, cool water. That’s how much freshwater a typical large, cloud data center complex with cooling towers used on average in 2017, even though fresh water is a dwindling and limited resource worldwide, especially in hot, dry areas of the globe. Clearly, data centers have a conservation challenge ahead of them.
Now, I’m sure you have heard the adage ‘necessity is the mother of invention’. So, it should come as no surprise that the industry has attempted to tackle this issue in a variety of ways – but unfortunately without much success – yet. Many of the solutions in recent years have certainly improved energy efficiency, but water usage remains high. Open cell towers are still way too common–place for an industry that knows it has a water problem.
And because Data Centers have this drinking problem, it is imperative the industry finds the most efficient and cost-effective solution regarding water usage – without sacrificing reliability. In short, low-water to no-water data centers are becoming a necessity for the market.
Data Centers Wow Clients with Low WUEs
First, what’s a WUE and why should you care? WUE stands for Water Usage Efficiency and it is just as important as the better known PUE (Power Efficiency Usage). The Green Grid Data Center Maturity Model (DCMM) sets standards for sustainability in several key areas including power, computing, storage, network, and yes water. They rate efficiency maturity levels on a scale from 1-5. If you are a 5, you can stop reading now…you have reached maximum efficiency. All others, keep reading.
Efficiency recommendations could include hot-aisle or cold-aisle containment to improve airflow management and reduce cooling loads, increasing the cold-aisle temperature set points, installing some form of economization to the cooling system, implementing data-center-wide monitoring and controls, conducting an energy efficiency audit, identifying and removing comatose/orphan/unused servers, and upgrading to higher-efficiency servers.
All of these strategies translate into utility bill and operational savings that also conserve overall natural resources, such as the water used onsite for cooling, or the water used to generate the electricity which runs the data centers.
The Aligned Solution: “Free Cooling”
Using a patented heat sink design that is closely coupled to the server racks, Aligned has been able to not only capture the heat generated by the servers more efficiently, but transport and reject it to the atmosphere using dramatically less energy and resources than the traditional CRAH systems.
The specially designed heat sinks, coupled with the use of hot aisle containment and an advanced volumetric air flow control strategy, enable Aligned to capture the heat at the source in a highly efficient manner. This solution trifecta results in a considerably lower airside static pressure drop, while minimizing bypass and maximizing the Delta T across the heat sink, which allows for dramatically less fan power and significantly higher return water temperatures.
Having higher return water temperatures is, of course, a great benefit where economization is concerned. An economizer system works the cooler outside ambient air against the warmer water to reject as much of the heat without using refrigeration.
This is where Aligned’s system sets itself apart. Their CACTUS cooler combines the best of wet and dry waterside economization, with industry leading maglev trim refrigeration. Through the use of their specially designed economizer coil and evaporative assist, the cooler is able to reject the heat very efficiently using only a modicum of fan power. Because of the close approach between the entering scavenger air and leaving water, the cooler essentially wrings out as much benefit from the ambient air as possible. And since water is used very sparingly by the evaporative media, this precious resource is conserved.
When the ambient air is no longer able to provide all the cooling needs, Aligned turns to centrifugal compressors for trim cooling. The system has the ability to start at very low power and can vary its output in a very granular way. One other benefit to the system is that the condensing section sits in the evaporatively cooled air stream, so when the system is running evaporative assist, it benefits from lower condensing temperatures and an improved coefficient of performance.
In addition to industry leading efficiency and sustainability, the Aligned Data Center Cooling System can be setup and installed to run dry. This solution benefits customers looking to operate without the use of water, while still maintaining lower connected power and lower PUE’s.
