There are opposing forces occurring right now in the data center industry. It seems that while big facilities are getting bigger, there are also architectures that are trying to shrink footprints. So as a result, densities are increasing.
Part of the conversation is shifting to density efficiency, being able to support an economy of scale but also the ability to support that in a much more sustainable manner.
Follow the Customer’s Journey
For most, especially over a multi-year transition, companies must be able to accommodate wide ranges within the same facility. It’s about balance and a return out of the portfolio striving for efficiency with technology and what will benefit the company over time. Next question…what kind of cooling is needed to meet the customer’s journey?
While new facilities may get a lot of airtime in the news, not everyone is trying to build massive data centers. Many are trying to fill the spaces they already have.
Improving transition v/s managing efficiency
The concern becomes one of reconciling immediate needs with that of the future
Now is the time for the data center community to ask reflectively and respectively what this current transition looks like for them? Are they trying to improve operations, or manage efficiency, and how can this transition go more smoothly?
It’s understandable to want to design for 12 – 15 kW per rack, so companies are prepared for the foreseeable future, but the reality for many operators is still in that 6, 8, 10, 12 range. So, the concern becomes one of reconciling immediate needs with that of the future.
Scalability and Flexibility Go Hand in Hand
It’s important to achieve elasticity to support the next generation of customer types. So as an example, the question being asked in the market today has become how companies individualize the ability to support hot spots efficiently without burning square footage.
Since they are predicting a five, or even 10-year horizon in some cases, space design needs to remain flexible. Do they keep the design adaptable to accommodate the possibility of air-side distribution or a flooded room or the need to go back to chilled water applications for the chip or cabinet-level cooling to support a higher density level?
Energy-efficient cooling solutions
Data Aire has dedicated their teams to research, to create the most scalable, and energy-efficient cooling solutions
When companies discuss cooling infrastructure and the need to scale over time, it’s important to understand that they are talking about designing for three-six times the density for which they have been designing for up until this point.
Since computer rooms and data centers consume large amounts of power, computer room air conditioner (CRAC) manufacturers, like Data Aire, have dedicated their engineering teams to research, to create the most scalable, flexible, and energy-efficient cooling solutions to meet their density needs.
Need for precision cooling systems
It boils down to this: to meet the density outlook and stay flexible, what kind of precision cooling system can support the need to maximize server space, minimize low-pressure areas, reduce costs, and reduce requirements?
Companies should be encouraged knowing that this ask is achievable in the same kinds of traditional ways, with no need to reinvent the wheel, or in this case, the environmental control system. There are a variety of solutions to be employed, whether DX or chilled water lots of different form factors, one ton to many tons.
Chilled water solutions
Chilled water solutions may be an option because they are satisfying the density increase simply by higher CFM per ton
So, whether companies are thinking about chilled water for some facilities or DX solutions (refrigerant-based solutions) for other types of facilities, both can achieve scale in the traditional perimeter cooling methodologies without the need for completely rethinking the way to manage the data center and the load coming from the servers.
Chilled water solutions may be an option because those systems are getting much larger at the cooling unit level; satisfying the density increase simply by higher CFM per ton. Multi-fan arrays are very scalable. And companies can scale down from 25 to 100 percent for the delivery, depending on whether they are trying to scale over the life of the buildout or they are scaling back to the seasonality of the business for whoever is the IT consumer.
Dual cooling systems
DX solutions are achievable from a good, better, best scenario. Good did the job back in the two to four kilowatt per rack days. However, nowadays, variable-speed technologies are well established, and they can scale from 25 to 100 percent just like chilled water.
Data Aire’s engineers are seeing more dual cooling systems designed at the facility level. And so, dual cooling affords the redundancy of the infrastructure. Of course, that’s important in the data center world. And it also introduces the opportunity for economization.
Density, Efficiency, and Economy of Scale
The entire concept of doing more with less, filling the buckets but still needing the environment and ecosystem to scale is playing an important role in the transition operators are facing. With regards to greater airflow delivery per ton of cooling, it’s extremely achievable without the need to dramatically alter the way companies operate their data center, which is essential because every operator is in transition mode.
They are transitioning their IT architecture, their power side, and their cooling infrastructure. An efficient environment adapts to IT loads. The design horizon should keep scalable and efficient cooling infrastructure in mind to help future-proof for both known and unplanned density increases.
