The Components of a Data Center

A data center is a physical location utilised by businesses and organisations to house computing and networking equipment for the purpose of collecting, storing, and delivering shared applications and data. They must contain adequate storage and power and be carefully temperature-controlled to make sure all the elements can function correctly without losing power or overheating. Data centers can contain routers, storage systems, servers, firewalls and more, and the units are stored in data cabinets in rows called data halls.

Since the turn of the century, the importance of data to businesses has continued to grow. Data centers, therefore, are required to process data quickly and efficiently. Standard personal computer networks and IT systems do not have a high enough processing power to handle the sheer amount of data modern businesses require for their day-to-day operations. 

Data centers often house many backup components and are protected by several layers of security measures, highlighting just how important the smooth running of the data center is to modern-day businesses.

A common component of any data center are servers. A server is a saving location and is connected to a network to make that data accessible to another computer program. They are fast and powerful processors of data and may be dedicated to single or multiple applications, or a specific client. Storage infrastructure is also utilised to run these servers.

Network infrastructure connects servers, as well as data center services to end-user locations. Networking equipment is necessary to maintain a high-bandwidth network between servers, allowing data to be shared throughout the data center.

The most important component of a data center, however, is the cooling system. Specialised equipment designed to handle large amounts of data every second can produce large amounts of heat. Overheating can be very damaging to server equipment, and if any crashes occur and the equipment is damaged and needs to be repaired or replaced, this can cause significant delays for businesses who need to access their data. Computing equipment that is overheating can also pose a fire hazard, so it is important to prevent this for health and safety reasons. Keeping the temperature of a data center carefully regulated can prevent these problems before they happen and keep everything running without an issue.

Best Practices for Server Rack Cooling

Server racks are important to the smooth and efficient running of a data center. A server rack is a structure specifically designed to securely house the important technical equipment within a data center, such as servers and routers. They help to keep equipment organized, while helping to maximize the floor space within a data center.

The technical equipment in a server rack is designed to handle large amounts of data every second and can produce large amounts of heat. Keeping server racks cool is essential to stop this equipment overheating.

Data centers usually contain specialist equipment to keep the entire room cool, however, it is also important that the individual server racks themselves are kept cool. Even if the data center as a whole is kept cool, the inside of a server rack or cabinet could still overheat.

Overheating can be very damaging to server equipment and can cause it to stop working. This can cause significant delays for businesses that need to access their data. Computing equipment that is overheating can also pose a fire hazard, so it is important to prevent this for health and safety reasons.

Server racks come with elements designed to keep equipment ventilated, however, this on its own is not enough to keep the racks and equipment cool. There are other practices you can put in place to help keep your server racks cool.

Airflow in the server racks should be managed to ensure that every component within the server rack receives cool air and remains at a safe temperature. The airflow should also be good enough to prevent the build-up of heat/hot spots. Also, the doors of a server cabinet should be perforated or removed altogether to allow an adequate flow of air.

It is also important to keep the data center itself at a cool and safe temperature. You can’t keep a server rack cool if the room temperature of the data center is too warm or overheating.

The temperature of each server cabinet should be carefully monitored and regularly checked. It may also be necessary to have more than one temperature monitoring point within each individual server rack.

At USystems, we provide a range of innovative cooling solutions, that help data centers stay cool. We provide local and global scale coverage, offer customer support from inquiry to installation, and look to build long-term partnerships with our clients. USystems are at the forefront of modern data center cooling.

Why Data Center Cooling is so Important

A data center is a physical location utilised by businesses and organisations to house computing and networking equipment for the purpose of collecting, storing and delivering shared applications and data. Data center cooling is all about controlling the temperature inside your data center to reduce heat. In order to maintain optimal performance of your computing infrastructure, you must maintain the correct room temperature for your hardware. Failure to manage temperature and airflow in your data center can lead to a risk of overheating, causing computing hardware to stop running properly and potentially leading to a fire risk. As IT systems become increasingly complex and powerful, the amount of heat they output has also grown. Cooling solutions therefore have and will continue to be, an essential part of server hosting.

Cooling solutions help your computing infrastructure to perform at an optimum level, and can potentially increase the lifespan of your technology. The USystems range includes Rear Door Coolers, In-Row Cooling and LX Plant cooling solutions. Our aim is for data centers to be better, scaleable, and also sustainable.

What do Micro Data Centers Do?

Micro data centers and Edge computing are recent innovations that aim to decrease the delay issues users often face when processing large amounts of data. A Micro Data Center is a small-scale modular data center that includes computing and storage infrastructure, designed for workloads not requiring traditional large-scale facilities. Their small size means that they can be used in locations where it would be impractical to use traditional data centers. Micro Data Centers allow for ‘Edge’ computing – this is where data centers are placed closer to the point of utilization.

Edge computing is a local source of processing and storage. They can provide several benefits to your business:

  • Reduce latency (the time it takes for data to become available). Edge computing allows for local processing, meaning data can be processed and stored faster. This creates faster working speeds for your company. The longer the distance between where you work and your data center, the more time it takes to deliver digital services, as well as increasing your bandwidth costs.
  • Micro Data Centers are smaller in size. This means you can have more options of where to deploy it. You can also pay for exactly the size you need, whilst having the ability to scale up at any point. Micro data centers take up just one square meter of floor space and require no infrastructure, so can easily be installed in existing office space.
  • Faster deployment speeds. The smaller scale of Micro Data Center solutions means that they can be installed and set up quicker than regular data centers.
  • Micro Data Centers are reliable and generally come in modular designs, meaning that the design is standardized, and parts can be replaced easily and efficiently.
  • All this means you can reduce costs and save money for your business.

Edge computing can be very beneficial to businesses that are experiencing problems with latency but do not have access to their own full-size data center. USystems offer Edge platforms that can be deployed in a range of environments, including offices, classrooms, labs, and data centers. Our Edge-ready solutions and Micro DCs guarantee high-level availability anywhere that requires IT to be closer to the end-user. The modular and compact design of our plug-and-play Micro DC solutions allows for fast deployment in multiple environments.

Where localised server rooms of the past took up large amounts of space or needed their own building, this isn’t the case with micro data centers. An advantage of a micro data center is that it can be easily deployed into existing office space without needing specialised infrastructure. They also require minimum upkeep, allowing you to focus your time on your business.

At USystems we provide local and global scale coverage, offer customer support from inquiry to installation, and look to build long-term partnerships with our clients. As well as developing high-quality and innovative data center cooling technologies, we also look to be sustainable and lower the amount of energy we use, helping your business to reduce its environmental impact.

Liquid Cooling: Benefits and Challenges

Over the last few years, Data Centers have raised their profile significantly. As such the industry has come under a significant amount of scrutiny due to inefficiencies of power, water wastage and their overall carbon emissions.

Accordingly Data Centers today are under extreme pressure to become more sustainable in all the areas in which they negatively impact on the environment.

This is not an easy fix, and one that most certainly can’t be concluded overnight. There are however significant changes that can be adopted at relative speed to allow for smoother transition.  For example, switching from fossil fuel supply to cleaner electricity supplies.  This can be completed with relative ease through securing renewable energy bonds with a supplier.  It should be said however, that whilst renewable energy is being built at a fantastic rate, the supply is still finite and until this is more ubiquitous, demand for Data Centers, as other concerns, needs to be reliable.

What is better than using renewable energy?

Using less energy overall to improve its availability elsewhere and reduce the wider grids reliance on fossil fuels.

In this document, we aim to provide information on Data Center cooling methodologies and the affects they have on the facilities in which they are embedded, in particular the benefits and challenges of liquid cooling.

Multiple Choices

When talking about next generation Data Center cooling, it’s important to realise that there are now multiple alternative choices as there are many next generational cooling methodologies available to design engineers, each with their own intricacies to be navigated.

kW Duty Deployment

In 2006, the kW per cabinet capacity was around 1 – 1.5kW per 42RU cabinet, increasing to around 2.4kW per 47RU cabinet in 2011.  The Data Center industry responded by building facilities that could cope with 5kW per cabinet average which was seen to give the industry significant flexibility for the foreseeable future, however, this requirement was surpassed in 2017.

Because the advancements of the Hardware have increased, the Data Center has had to adapt to overcome the challenges of increased kW demand per cabinets in several ways.

One of the options was to share the capacity. This meant that the design of the facility which had allowed for 5kW per cabinet could facilitate a 10kW cabinet but this would mean a cabinet next to it would have to remain empty to keep the balance.

When real estate is at a premium, this is a costly waste which in turn either has to be charged to the customer or absorbed by the Data Center.  With the trend for cabinet kW increasing, it raises questions on the existing design scalability.  This could result in a Data Center being up to a third empty or unusable space if the industry continues to increase power demand.

Global Average Cabinet kW Requirements and Data Center Design and Build Deliverable per cabinet

Because of the advancements of the Hardware and its increase in duty, some Data Centers have added air controlling adaptations and additional hardware to their existing design to aid in the increased cooling demand.

These adaptations are typically, Aisle Containment, In row Cooling units and in some design cases higher duty air vent tiles.

Adaptations such as the ones shown have supported the Data Center facilities well, meaning where extreme kW duty cabinets were required, they were able to facilitate and deliver the necessary cooling required. 

However this came at an increased cost , and often still had a typical cooling limit of around 30kW per cabinet.  So even these technologies are not capable of efficiently cooling the latest cabinet densities.

kW Duty Per Technology and its Efficiency

The above graph demonstrates significant increase in kW demand for facilities where global average kW requirements per cabinet are closely aligned to kW per cabinet Data Center design, not allowing for the facilities to evolve to meet higher demands where required.

However, as there is now a bigger a drive for the industry to be more sustainable, this means we simply cannot continue designing facilities with so many existing conflicts to achieve a better future, for both operators and those utilising colocation space.

We have to look to introduce new more efficient technologies which can deliver both within the existing or new build infrastructure.

kW cooling capacities per technology need to be reviewed. The graph below covers the kW duties the technology supports as an average.  There are even some indirect cooling technologies which could exceed the kW duty shown, dependent on the climate it is deployed in.

White Space Data Center Cooling

The Data Center has always been the key foundation to support IT hardware, with the capability to provide the space, power and cooling for exact requirements. However as the Hardware has evolved and increased in power demand, the design architecture and specifically the cooling ability of the Data Center has started to fall behind in its capability.

This is where the opportunity for Data Center designers to re-evaluate their existing design criteria and utilise alternative technology available which can enhance the future of their facilities and in turn the efficiency and sustainability of the Data Center.

Here we examine and give an insight into the benefits of some existing and new technologies helping to address the increased demand for Data Center white space cooling.

Immersion

Immersion cooling is a relatively new technology. There are two versions of immersion cooling, single phase and two-phase. Both are a technology that allows servers and other components that traditionally were in a free-standing cabinet, to now be submerged in a tub configuration with thermally conductive dielectric fluid. With this method, the need for air cooling around the Hardware is eliminated, including the fans within servers, however supplementary cooling is still required due to the excessive heat within the overall room from such a large system with significantly high temperature fluid, this supplementary cooling will typically be between 10-20% of the overall loading.

In a single-phase system servers can be installed vertically in a dielectric fluid that is thermally conductive. Heat is transferred to the liquid medium through direct contact with server components and removed by heat exchangers in a CDU.

The other challenge that is often lost is the use of ‘Dual phase’ or ‘Two phase’ systems, it is important to remember that these are in essence refrigerants which have a global warming impact which potentially can be thousands of times its own weight in CO2 equivalent.

Direct chip level cooling

DCLC or Direct Chip Level Cooling is a highly efficient heat rejection system with water or one- or two-phase dielectrics to reject heat from chip sets.  Fast becoming one of the ‘go to technologies’ as an attractive way to boost or supplement the base load of air-cooling for higher density applications above that of Aisle Containment.

This system works well in new or retrofit DCs and compliments existing CHW (chilled water) design in a very efficient way which can extend or augment many Data Center facilities.

Supporting any server, including a number that are pre-integrated, while also Supporting potential for using higher fluid EWT/LWT with improved free cooling aspects.  The technology is deemed Safe and reliable  and has potential for heat recovery with process water, however this is likely to need a CDU for heat transfer, these CDU systems also need to be more local and consume vast areas of the white space.

DCLC is an excellent technology that has taken Hardware cooling to the next level, by treating just the GPU/CPU however it typically removes between 50-70% of the total IT heat load.  Due to this you will still need another form of cooling to eradicate the additional heat.

The heat sinks and other materials typically get removed and replaced for every IT refresh due to  variations in hardware design which is extremely costly, up to 60% of initial capital expenditure in some cases.

DCLC is a good solution for HPC and deployment in Colocation existing Data Centers reflects the reality that this form of equipment will normally require supplementary cooling for the foreseeable future, as it is concentrated at the main CPU/GPU heat sources. It serves a purpose in HPC hardware applications and allows for some support on deployments in traditional Data Center / MTDC environments.

It is a more mature approach than immersion cooling, and the reports of leaks, that would normally be a cause for concern are taken away by working with key established providers, however given that there are a significant amount of parts used in this type of deployment the TCO model can be challenging due to lack of forward IT compatibility and significant CAPEX replacement and deployment costs.

Rear Door Coolers (RDC)

RDCs have been around the longest of all the next generational white space technologies, all be it initially in passive deployments. Since the emergence of active RDC or RDHx (Rear Door Heat Exchangers) some models offer the highest heat rejection capabilites in the industry today.

Our product, the ColdLogik RDC is designed to run on liquids such as water or harmless synthetic fluids, potentially improving efficiencies and increasing flexibility, however unlike the other new technologies, it can also negate the need of mechanical cooling. 

Most RDCs utilise a closed loop system, meaning they don’t consume water.  They also waste significantly less water than traditional Data Center deployments, and in some scenarios would consume no water for the full year without mechanical cooling.  As some Data Centers are facing massive pressure to reduce the amount of potable wast water they utilise, this would be of significant benefit to them and the local communities they impact.

The ColdLogik  system cools 100% of the room load thereby mitigating the need for any additional cooling, improving efficiencies significantly and saving real estate.

This type of technology is non-intrusive, and as it is AALC (Air Assisted Liquid Cooling), it poses no risk to equipment warranty whilst allowing for easy integration and deployment into any existing environment.

The cost of the RDCs and components to deploy mean it is cost effective for the overall TCO and not as CAPEX heavy as other technology.  It also can deliver full PUEs of 1.035 – 1.09 meaning the OPEX is also significantly profitable due to the savings the doors enable.  This is achieved when delivering up to 98% power usage savings comparable to traditional CRAC/H air cooling, up to 83% comparable to traditional aisle containment cooling and up to 45% comparable to in-row cooling.

ColdLogik systems will support in excess of 200kW per cabinet whilst allowing N+1 redundancy which is a unique attribute in the market place.  There is no need for specialist hardware to allow for integration.

Free cooling is the true goal for ColdLogik RDC systems and this can be achieved even in the harshest environments. RDCs are compatible with almost all external plant options including chillers, dry coolers,water towers, bore holes, rivers and lakes. The RDC also allows for higher water differentials enabling the use of heat recovery where a use exists for the waste heat.

Some RDC manufactures also require CDUs, which when deployed may need to take up space close to the deployment whereas ColdLogik systems can be deployed onto any existing cabinet allowing for simple retrofit options, without the need for CDU systems.

The RDC is a proven technology and the most mature and versatile of all next generational white space Data Center cooling.  Efficiently delivering 100% of heat negation, more than all the other next generation technologies. It saves water, a key element the DC industry needs to focus on and also delivers power and space savings alongside huge carbon savings.

Water Scarcity: An overview and how it will affect Data Centers

Water Scarcity, an overview

The presence of water around IT equipment was introduced mainly back in the 1970’s, at a time when mainframes were traditionally located within offices.  The mainframes were primarily situated in and around the desks where people were working and as result the room environment became a lot warmer and more uncomfortable for the personnel. The challenge to change this situation soon became apparent and that some form of cooling was required to address this increase in temperature. A solution that would meet the requirements of both the people in the organisation and the environment that the equipment needed to survive in and thus IT air conditioning was born.

In order for the personnel and IT equipment to co-exist it was deemed that a room temperature of 21°C (+/- 1°C) and an air humidity level of approximately 50% had to be achieved. This was only going to be possible using specialist air conditioning systems.

In the late 1980s and 1990s office spaces and IT rooms were becoming separated from each other and the IT rooms became more commonly recognised as a comms room/computer room (or data centers as we now know them). 

Water was the cooling medium used in the air conditioning systems, these were referred to as Computer Room Air Handling ‘CRAH’ systems.  Although this was situated some distance from the IT itself, water was present in the surrounding areas and allowed the room to reach the set point temperatures and humidity levels.

Since data centers became the dedicated supporting platform for IT, they have utilised water in multiple ways, from fire suppression to perimeter cooling for CRAH systems. However, we now appreciate that water is our most valuable natural resource and it needs to be used wisely.  Many areas of the world are already suffering from water scarcity and this is becoming more widespread across the globe which is a major concern and obviously harmful to the human race, wildlife and the planet.

Water Scarcity, why?

To address this we need to relay some facts about water.  Firstly, of the 100% of water on the planet, only 2.5% is actually only available to drink, known as ‘fresh or potable water’, with the remaining 97.5% as salt water.  These statistics become rather alarming, when you consider there are over 7.8 billion people (at time of writing) on the planet, all of whom need water to survive.  Of the 2.5% of fresh water, some of it is not actually available with approximately 68.9% in glaciers, 30.8% is groundwater and 0.3% is in lakes and rivers.

How does it occur?

Water scarcity occurs when the demand (due to agriculture, cities and environment) is higher than that of the available resource.  Even today over ⅓ of the population lives in an area where their water supply is not enough to fulfil demand or it has been compromised.  This is a massive issue and one which is happening all over the world.  Based on current projections it is predicted that this will be an issue for ⅔ of the world’s population by 2025 – less than 5 years away!!

There are two types of water scarcity, physical water scarcity and economical water scarcity. Physical water scarcity is not having enough water to meet our daily needs and economical water scarcity is when human, governmental, institutional or financial capital limit or throttle access, even though water in nature is free to access the scarcity requires it to be metered out to enable a fairer distribution.

 

So, how do we measure water usage?

Water Usage Effectiveness ‘WUE’ is a sustainability metric created by The Green Grid in 2011 to attempt to measure the amount of water used specifically by data centers cooling their IT assets. To calculate simple WUE, a data center manager divides the annual site water usage in litres by the IT equipment energy usage in kilowatt hours (kWh). Water usage includes water used for cooling, regulating humidity and producing electricity on-site.

How can you improve this usage?

There are multiple technologies available which limit water usage, without having to resort to potentially harmful chemical solutions. For example, in order to cool the equipment efficiently and effectively, retrospectively or as a new build, without the need to redesign is to use a Rear Door Cooler the RDC.  Unlike traditional CRAC (refrigeration/mechanical cooling principle) systems, the RDC removes the heat directly at the source and the air dispelled into the space is the desired room temperature. CRAC systems typically mix colder and warmer air to provide the room environment which isn’t the most efficient option.

Conventional air cooling traditionally consumes significant energy when using mechanical chillers, one way to reduce and potentially eliminate the additional energy use/wastage is by utilising adiabatic cooling. Whilst significantly improving efficiencies on one hand this exponentially increases water usage to facilitate evaporative cooling.  The major downside however is the growing scarcity of potable water in certain geographical locations.  RDC’s can utilise water from natural sources so as not to disrupt the availability of drinkable water in the vicinity. Sustainable natural water sources such as lakes, riverbeds, aquifers, bore holes, rainwater and even sea water.  Water is not taken, polluted or removed, simply flowing around the heat exchanger and returning back to its original location, recycling at its best!

How will this affect the data center market?

Reports suggest that there are data centers which use millions of gallons of water per day to keep them cool.  This along with power usage, is one of the hottest issues for data center managers, operators and owners as they try whatever they can to reduce their usage of both without affecting current and future performance.

With insight and the desire to change to more sustainable solutions, data center operators can utilise technology available today, such as ColdLogik by USystems which can reduce the amount of water usage to nearly net zero gallons of water, whilst also saving up to 93% cooling energy.

It is immoral and soon to be illegal in a lot of States, to utilize these huge amounts of water for a data center, especially when restrictions are close to being implemented in certain regions to stop the general public from using the natural resource of water due to its scarcity.

Conclusion

In conclusion, the ColdLogik RDC would likely save a minimum of 58% up to 100% water that would otherwise be consumed by traditional cooling methods. When looking to improve water usage with a product that is tried, tested, highly regarded, multi award winning and successfully deployed worldwide for over a decade. 

By utilising Air Assisted Liquid Cooling ‘AALC’ you can effectively increase the water temperature to the point where adiabatic cooling is no longer needed, giving the best of both worlds, no excess or drinkable water wasted and better energy efficiency with a simpler site set up and requirement.

How data centers enable cloud computing

Many online processes today would not be possible without cloud computing. By remotely accessing data centers, businesses and consumers can rapidly access, process and share complex data with one another. Social media, instant streaming, complex customer databases and E-commerce all rely on cloud computing to connect people and corporations to their data and demand is only increasing.

Devices such as smartphones and personal computers in homes and workplaces now have more powerful data processing capabilities than ever before, but without data centers and wireless internet access, these can still only do so much.  Cloud processing and cloud storage mean that users do not have to have their own complex IT infrastructure in order to use, view and process lots of data. Businesses can save money by not having to pay for and maintain their own on-site data center, and can instead rent the use of a remote data center accessed via the cloud to complete complex data processing requests for them. Consumers can also benefit from services such as vast email storage, online photo backup, digital streaming services, online gaming and much more.

Cloud data centers are centralised locations, containing powerful computer hardware capable of processing high amounts of data at rapid speeds, either used by one business or shared by many. Users access the cloud data center remotely, allowing the data center to handle their data processing and send it back to them in real-time. However, cloud data centers are often located very far from the business or the user. This distance, sometimes spanning continents, can lead to delays in data transfer known as latency. This slow performance can be detrimental to businesses whose customers expect instant results and ongoing latency could lead to losing customers and profits. As a way to tackle this, micro data centers can be deployed into business offices to provide a small amount of processing power at the data source, bridging the gap between the end user and the cloud data center to speed up processing and eliminate latency issues. Micro data center solutions from USystems take up just a square meter of floor space and have soundproof options so no complex infrastructure is needed and there are minimal distractions. If your business relies on the use of a cloud data center, a micro data center could help to improve your processing speeds and increase customer satisfaction.

Data centers help to power our daily lives and enable users to process more data than ever thought possible. USystems and Coldlogik help to keep data centers running smoothly and efficiently by providing data center cooling solutions that can meet demand. From in row coolers to rear door heat exchangers, our cooling solutions are designed with the future in mind, effectively cooling data centers of all sizes with a minimal impact on the environment. Our range of micro data centers also helps businesses stay up to speed and make the most of cloud computing. Whatever the size or use of your data center, we have a solution for you.

The future of data center cooling

Data centers often come under fire for their high energy consumption, and people often question whether or not a sustainable future for data centers is possible. In the past, data center cooling consumed vast amounts of energy and wasn’t particularly efficient. However, advancements are being made daily to ensure that data center cooling has a future with sustainability in mind.

Computer Room Air Conditioning (CRAC) and raised floors were once the most common method of  keeping data centers cool, but this method wasn’t energy efficient as it used vast amounts of energy without being able to maintain an optimal cooling environment. Used in combination with aisle containment, CRAC is slightly more successful at keeping data center computing equipment cool, but with denser and more powerful hardware becoming the norm, CRAC cannot keep up with cooling demand.

More and more data center cooling solutions are now being engineered with sustainability and energy efficiency in mind. It is vital to generate as much cooling output as possible with minimal energy consumption and minimal impact on the environment. Solutions such as in row cooling have emerged in recent years as a way to efficiently cool data center equipment with precision and accuracy. In row coolers are positioned within the rows of data centers as the name implies, extracting heat from the hardware at the source rather than attempting to cool the room as a whole, which provide much more precise and effective cooling that doesn’t waste energy. In row coolers take up less space, don’t require the use of raised flooring, and when coupled with aisle containment can save up to 60% in energy consumption compared to CRAC. In row cooling is an easily scalable solution too, meaning that as your business grows new inrows can be added along with new cabinets to ensure that your cooling solution is ready to keep up with the future of your data center.

Water cooling for data centers is also a much more popular and efficient form of cooling instead of relying on air. Water cooling systems run contained cold water along computing equipment, extracting heat as it passes. Rear door heat exchangers combine the best of both worlds, using a combination of air and water cooling that is highly effective and efficient. Fans draw ambient air into the rack, and hot exhaust air is drawn over cooling fluid and expelled into the room as cold air. This maintains an ideal and efficient cold temperature throughout the whole room without the need for additional air conditioning units. To ensure a sustainable future for water cooling, innovations are being made, such as using sea or river water instead of chilled fresh water to reduce water consumption. In some data center facilities, the waste hot water is recycled to be used as hot water in bathroom facilities, reducing water consumption further.

USystems and Coldlogik are committed to creating data center cooling solutions that are robust, efficient and future-proof. If you’re looking for state of the art cooling with a great return on investment, check out our range today.

The benefits of Edge computing

Edge computing can be very beneficial to businesses that are experiencing problems with latency but do not have access to their own full-size data center. By introducing a local, self-sufficient micro data center into your business premises, large amounts of data can be rapidly processed without putting a strain on your bandwidth. Bringing data processing capability closer to the data source means that latency can be reduced and processing speed can be significantly increased, reducing wait times and leading to all-round better productivity and satisfaction.

Cloud storage and access to cloud-based data centers has revolutionised the way businesses handle their data, providing powerful data processing capabilities to businesses that do not have or cannot afford their own complex IT infrastructure. But with increased demand and reliance on cloud storage throughout all industries, lag and latency have become big issues as these centralised data centers struggle to meet demand. When data is processed far from the source in a cloud-based data center, it has a long distance to travel which is where the problem of latency arises. Edge computing helps to combat these issues by enabling businesses and organises to locally process data using a micro data center, also known as an edge data center. Micro data centers act as a bridge between you and your data center, enabling real-time data processing at the source whilst still allowing access to your powerful cloud-based data center.

Where localised server rooms of the past took up large amounts of floor space or needed their own dedicated building, this isn’t the case with micro data centers. A huge advantage of a micro data center is that it can be easily deployed into existing office space without needing specialised infrastructure. Taking up less than a square meter, they can be easily installed into your place of work, either into a dedicated room or incorporated into your office space. If you’re concerned about any disturbances, our soundproof micro data center solutions create minimal noise and disruption, allowing you to get on with the important work with no noisy distractions.

Edge computing benefits businesses by bringing together the best of both worlds. The convenience and processing power of a cloud-based data center is combined with the rapid speeds of an on-site data center providing local processing, resulting in a solution that is quick, convenient and affordable. With no need for expensive IT infrastructure or bandwidth, your business can benefit from the most efficient and effective solution whilst saving money on running costs.

What is ColdLogik?

ColdLogik from USystems provides innovative, precise and award-winning cooling solutions for data centers of all types and all sizes. ColdLogik [cooling systems] are at the forefront of modern data center cooling innovation, pioneering energy-saving cooling that is sleek, modern and highly efficient in comparison to the CRAC systems of the past. From InRow cooling to rear door heat exchange, ColdLogik solutions are helping to keep data centers running as they should with a minimal cost and impact on the environment.

Rear Door Heat Exchangers

Rear door heat exchangers (or RDX) provide direct and precise cooling to data center cabinet units by cooling at the source of the heat. RDX can also be described as Air Assisted Liquid Cooling (AALC) which combines the best of both worlds. Air from the room is drawn into the unit to provide some ambient cooling, and the hot air that is expelled from the unit is passed through a liquid cooling system and converted into chilled air to be expelled into the room and provide extremely efficient cooling, not just to individual data cabinets but to the room as a whole. Rear door coolers can be easily installed without altering the current design of your data center, providing enhanced cooling capability with no hassle.

Inrow cooling

InRow cooling is exactly what you’d expect: cooling units installed into the data aisles to cool the rows instead of cooling the data center room as a whole, therefore providing much more efficient and easily-controllable cooling. InRow coolers take up much less space than older outdated cooling solutions and do not require a raised floor, meaning installation is fast, simple and straightforward. When combined with aisle containment to create hot and cold aisles, InRow cooling is up to 60% more efficient than CRAC cooling and does not require any additional room cooling; inrows are powerful enough to maintain a cool environment throughout your data center. ColdLogik is proud to offer the most efficient InRow coolers on the market, and our InRows are scalable by design, enabling you to add more cabinets and InRows to keep your data center cool as your business expands.

LX Plant
