Self-healing wires and cables for data centers - featured image for blog

Data center outages are a nightmare scenario for any business. A single hour of downtime can cost millions of dollars in lost revenue, productivity, and damaged reputation. The advent of self-healing materials (trending technology) is transforming the cable industry, offering a new frontier in data center resilience. Imagine cables that can automatically repair themselves after being damaged, virtually eliminating the risk of unexpected failures. This isn’t science fiction – it’s the reality of self-healing cables.

In this article, we’ll explore the science behind self-healing cables and their numerous advantages for data centers.

Self-healing wires and cables for data centers

What Are Self-Healing Cables

Self-healing cables are a revolutionary innovation in cable technology designed to address weaknesses of traditional cables. These cables are engineered with special materials that enable them to repair damage autonomously, such as cuts, punctures, or cracks, without human intervention.

There are two main types of self-healing cables:

  1. Self-Healing Wire Insulation – This type of cable features insulation that can mend itself after being damaged. When the insulation is breached, the self-healing material reacts to the exposure, flowing into the damaged area and effectively sealing it. This healing reaction prevents electrical shorts, ensures the integrity of the signal transmission, and extends the cable’s lifespan.
  2. Self-Healing Wire – This type refers to cables where the conductive core possesses self-healing properties. In the event of a break in the conductor, the material can re-establish electrical connectivity, restoring the flow of current and preventing a complete cable failure.

The science behind self-healing cables is rooted in developing advanced polymers with unique chemical properties. Scientists designed these polymer materials to respond to damage by triggering a chemical reaction that forms new bonds, effectively “healing” the damaged area. This self-healing process happens at a microscopic level, but its impact on cable performance is significant.

Advantages of Self-Healing Cables in Data Centers

Self-healing cables offer many benefits for data centers, addressing critical challenges and paving the way for a more resilient and efficient future.

The cryptocurrency boom has been a double-edged sword. While generating excitement in the tech and finance worlds for its versatile uses, major debates around energy consumption have sparked everywhere. 

Crypto mining operations are notoriously power-hungry, with global estimates suggesting their energy use rivals that of entire nations. For data centers accommodating crypto rigs – stacks of graphics processing units (GPU) that consume up to 120 watts per GPU or 1000 watts per rig – addressing power efficiency is not just good environmental practice – it’s a business necessity!

That number may seem small if we’re talking about small-time crypto miners. However, crypto mining facilities or data centers with at least 50,000 rigs (consuming 180 megawatts) can quickly translate to millions of dollars in monthly electricity costs. To put things into perspective, 180 megawatts is enough to power 180,000 U.S. homes! 

This is where strategic cable management plays a surprising but crucial role. It might seem like a minor factor, but how cables are organized within crypto mining rigs, server racks, and throughout the data center can significantly impact power usage and overall efficiency.

Challenges of Crypto Mining in Data Centers

Massive Power Draw

Crypto mining rigs are designed to run at full capacity 24/7, consuming vast amounts of electricity. Unlike typical data centers that store and transfer data to where it is needed, where the operating parts are storage devices, crypto mining uses GPUs. These processing units are extremely power-demanding and are used all day at maximum capacity to acquire cryptocurrencies like BitCoin.

Heat Generation 

This continuous operation creates substantial heat output, straining traditional cooling systems and increasing energy costs. GPUs generate more heat than storage devices. GPUs can peak at 203°F (95°C). Storage devices like SSDs operate only at around 86°F to 122°F (30°C to 50°C), which dwarfs in comparison to the average operating temperature of GPUs at around 158°F (70°C).

Density Demands  

To maximize computing power, crypto rigs are often packed tightly into custom racks, increasing the thermal and power management challenges. Moreover, crypto mining facilities are relatively new, unlike traditional data centers that are now more standardized and with proper facility regulations. Hence, crypto mining data centers can design and create racks with poor efficiency.

Power Cable Red Flags – Avoid for Safety and Better Data Center Performance

Two SJT power cable for data centers

Data centers are the backbone of modern digital infrastructure. Yet, minor oversights like substandard power cables can jeopardize safety, reliability, and energy efficiency. Understanding these power cable red flags is crucial for ensuring optimal data center performance.

This article aims to help not only data center engineers and technicians. It’s also for IT managers who handle general networking and cabling for organizations with smaller IT infrastructures. Edge data centers and modular data centers in universities, retail, and hospitals will also find this article vital, especially for safety.

Power Cable Red Flag - SJT Cable in Hazard Background

Power Cable Red Flags 

Non-Compliant with Industry Standards – No Certification

It is important to ensure that your data center power cables meet the standards set by recognized industry bodies such as the Institute of Electrical and Electronics Engineers (IEEE), Underwriters Laboratories (UL), National Electrical Manufacturers Association (NEMA), or the International Electrotechnical Commission (IEC). 

Non-compliant cables may not have undergone rigorous testing for safety, performance, and reliability. Be aware of cables that lack proper certification marks or appear to have forged certifications.

Certification marks from reputable organizations like UL, CE (Conformité Européenne), and CSA (Canadian Standards Association) ensure the product meets specific safety and performance standards. Cables without these marks, or with counterfeit marks, are a significant risk that is not worth taking.

If your cable supplier isn’t able to show any form of certification, you may want to review your options. 

Inadequate Shielding and Insulation

Power cables with poor or missing shielding and insulation are another red flag. Proper shielding and insulation protect against electromagnetic interference (EMI), physical damage, and electrical leaks. 

EMI can cause data corruption and loss, while inadequate insulation raises the risk of shorts and shocks.

The IEC publishes guidelines on cable insulation requirements, emphasizing the importance of materials that can withstand the operational environment of data centers.

Here are some construction signs to look out for: 

  • Inconsistent Cable Thickness: Variations in the cable’s diameter along its length can indicate low-quality manufacturing and inconsistent insulation.
  • Easily Exposed Conductors: The cable likely has poor insulation quality if the insulation feels flimsy or the inner wires are easily exposed with minimal pressure.
  • Suspiciously Low Price: Extremely low compared to similar cables from reputable brands might indicate substandard materials and poor quality. Low pricing is excellent for business, but watch out for overtly low ones that seem unreasonable.

Incorrect Cable Gauge

Using an incorrect cable gauge (thickness) for your data center’s power load is a major red flag. The American Wire Gauge (AWG) system dictates a wire’s current-carrying capacity, and undersized cables will dangerously overheat, posing a fire risk and potentially damaging equipment. Data centers operate with high power demands, making this even more critical.

Incorrectly rated cables can also fail under stress. Always consult the National Electrical Code (NEC) and equipment specifications to select the correct cable gauge and type. Be careful of suppliers that will sell you lower-gauged power cables than what they advertise. Not only will an incorrect cable gauge mess up your data center power cable management, but it will also lead to safety issues and equipment damage.

Absence of Fire Resistance

Although there are plenty of data center power cable types available, all of them should at least have some fire-resistant rating. Power cables with zero fire resistance are a major red flag, especially for data centers. Fire-resistant cables minimize the risk of spreading fire and releasing hazardous fumes in case of a fire. The National Electrical Code (NEC) specifies the types of cables suitable for different environments, and it emphasizes the need for fire-resistant materials in settings prone to fire risks.

Plenum-rated cables are highly recommended for areas running through plenum spaces, such as above ceilings or below floors. These cables come with special jackets that reduce the potential of fire spreading and minimize the emission of toxic smoke in the event of a fire. This feature is crucial in data center environments where the safety of personnel and infrastructure is at risk from the rapid spread of fire and toxic emissions.

Dangerous Power Cable Manufacturing Practices in the Industry

Here’s a list of common issues in the cable manufacturing industry that you should avoid. If your cables have any of the characteristics mentioned below, they’re likely sub-standard and should be returned. 

Poor-quality copper used in power cable - avoid this type of power cable

Problems with the Copper Conductor

  • Poor-Quality Copper: Impurities in the copper reduce conductivity, leading to decreased current capacity, higher energy losses (as heat), and potential for overheating.
  • Low Copper Strand Count: Fewer strands within the conductor reduce the cable’s flexibility and increase the resistance, leading to heating and potential breakage.
  • Smaller AWG: Using a smaller gauge wire than required means the cable cannot safely handle the intended electrical load, creating a fire hazard.
  • Alternative Metals Dipped in Copper: This deceptive practice lowers the overall conductivity of the cable, leading to the same issues as using lower-quality copper.
  • Alternative Metal Alloys: Alloys of less conductive metals will create higher resistance in the cable, causing energy loss, heating, and reduced performance.

Issues with Terminals and Connections

  • Hollow Pins: These lack strength and reduce the contact area, leading to higher-resistance connections that can overheat and fail.
  • Sub-Standard Material: Cheaply made terminals can corrode, deform, or break, disrupting power flow and potentially causing dangerous short circuits.
  • Improper Crimping: Loose or incorrect crimping creates a high-resistance connection, leading to heat buildup and potential failure of the connection.
  • Misaligned Pins in Housing: Misaligned pins can cause short circuits, arcing, and damage to equipment.
  • Sub-Standard Inserts and Shells: Cheap materials lack strength and durability, increasing the risk of physical damage or loose connections to the cable.

Cable Construction Problems

  • Low-Quality Insulation Material: Inferior insulation and jacket material are more prone to damage, exposing conductors, creating electrical hazards, and shortening cable lifespan.
  • No Cable Filler: Without fillers, cables become unbalanced and prone to kinking. This can damage internal wires and make them susceptible to coming loose from the connector.
  • Using Recycled Plastics: Recycled plastics for insulation can be brittle and break down faster, increasing the risk of electrical shorts and safety problems.
  • Faulty Molding Time/Maintenance: Poor manufacturing practices affect the integrity of connectors and the overall build quality, leading to failures and potential hazards.

 Other Power Cable Red Flags

  • Fake Certifications: Power cables lacking legitimate certifications (UL, ETL, etc.) may not meet safety standards and pose a significant risk.
  • Falsified Testing: This indicates a disregard for safety and proper quality control.
  • Code Violations: Cables that don’t meet electrical codes are unsafe and may be illegal to use.
  • Low-quality Packaging: Substandard packaging can suggest overall poor quality and a higher risk of damage during shipping.

Data Center Liquid Cooling – Is It Time for an Upgrade?

Featured image of a Liquid Cooling Data Center using immersion cooling

As the demand for cloud services, big data analytics and AI computations grows, data centers are housing increasingly dense and powerful computing equipment. This trend has led to higher heat loads, making efficient cooling not only desirable but necessary. In some situations, traditional air-cooled systems, once the backbone of data center cooling, are now being supplemented and even replaced by data center liquid cooling solutions.

In this article, we explore how far our cooling innovations have come and uncover the reality of today’s liquid cooling landscape. We’ll break down the tech news outlet hype around liquid-cooled data centers – what are the options? What makes it special? Is it suitable for every data center? And is this technological shift inevitable? Let’s dive in.

A Liquid Cooling Data Center using immersion cooling technology

Immersion Cooling Technology for Data Centers

Why is Liquid Cooling Superior?

Liquid cooling is superior in data centers due to its higher thermal conductivity – liquids conduct heat up to 1,000 times better than air – allowing it to efficiently remove heat directly from high-power computing components. 

This direct heat removal leads to significantly lower operational temperatures, enhancing the performance and longevity of sensitive electronic equipment. Additionally, liquid cooling systems are more energy-efficient than traditional air cooling, reducing operational costs and a creating a smaller carbon footprint.

Energy Savings

Another core benefit that liquid-cooled data centers enjoy is energy savings. In quantitative research conducted by NVIDIA and Vertiv, data centers that use liquid cooling systems reduced their total data center power consumption by 10.2% – an 18.1% reduction in facility power! From a financial perspective, this reduction is $740,000 less than from power-hungry data centers that consume $7.4 million annually.

Types of Data Center Liquid Cooling Systems

There are many data center liquid cooling systems in place – some more complex than others. However, these three are the most dominant ones in use today:

Direct-to-Chip Liquid Cooling

Direct-to-chip (D2C) cooling involves circulating a coolant directly over the heat-generating components, such as CPUs and GPUs. This method significantly increases cooling efficiency by removing heat directly at the source. D2C systems can use a variety of coolants, including water, dielectric fluids, or refrigerants, depending on the application’s needs and the desired cooling capacity.

Immersion Cooling

Immersion cooling takes liquid cooling a step further by submerging the entire server, or parts of it, in a non-conductive liquid. This technique is highly efficient as it ensures even and thorough heat absorption from all components. Immersion cooling is particularly beneficial for high-performance computing (HPC) and can dramatically reduce the space and energy required for cooling.

Rear-Door Heat Exchangers

Rear-door heat exchanger units are a hybrid solution, combining air and liquid cooling. These units are attached to the back of server racks, using a liquid-cooled coil to remove heat from the air exiting the servers. This method is often used as an intermediary.

Data Center Liquid Cooling Cons

“If liquid cooling is so great, why haven’t we implemented it in every data center?” you may be asking yourself. The answer is simple: we haven’t perfected the technology. There are still a number of cons that make this solution more of an option for massive data centers who are willing and can afford to take the risk.

Higher Initial Setup Cost

Implementing liquid cooling in data centers requires a substantial initial investment. This includes the cost of the cooling system itself, such as pumps, pipes, and liquid handling units, and potential modifications to the existing infrastructure to accommodate these new components.

Complex Maintenance Requirements

Liquid cooling systems are day-and-night more complex to maintain than traditional air cooling systems. They require regular monitoring for leaks, proper handling of the cooling liquids, and maintenance of additional components like pumps and liquid distribution systems, necessitating specialized skills and training (more initial expense). Moreover, modern servers that use denser equipment and computers require crane-system assistance for immersion cooling setups, which can be a massive infrastructure endeavor for data centers considering making the shift. 

Risk of Leaks and Liquid Damage

There is an inherent risk of leaks in any liquid cooling system, which can significantly damage expensive data center equipment. Ensuring leak-proof systems and having emergency response plans are essential, but they add to the operational complexity and costs.

Should Your Data Center Opt for Liquid Cooling Solutions?

Probably not. With the current tech and innovation, upgrading to a full liquid-cooled data center can be incredibly expensive with many unknowns. Even apart from its complexity and cost, there are no currently established standards for data centers to follow. However, we’re not saying that it’s a bad idea. 

Liquid cooling data centers have their place in the tech world, but it’s mainly for data centers ready to shell out billions of dollars. The ones eager to be at the forefront of the industry and pave the way for better big data analytics, AI computations, and cloud services. 

For edge computing and businesses requiring a more straightforward, more reliable solution – Modular Data Centers and All-in-One Data Center Cabinets can provide the same benefit without the hefty price tag. 

Are Liquid-Cooled Data Centers the Future 

Based on the current forecast, it looks like it. 

The global data center liquid cooling market is projected to grow from USD 2.6 billion in 2023 to USD 7.8 billion by 2028

But is it for every data center operator? Not at the moment. 

In the future, as more and more innovations come up, standards are created, and OEMs create more liquid-cooled-stable equipment, liquid cooling will become a more dominant cooling technology due to its efficiency and eco-friendliness.
