Optimizing Ethernet in Data Center Networks

Feature Ethernet Data Center Networks - AnD Cable Management Blog

Demand for faster data transfer, and more of it, has exploded exponentially over the last decade. Even before the pandemic, growth was already at exponential rates, but with the work from anywhere trend and more people gaming and streaming from home, demand rose even further. 

With it came an explosion in innovation, and a necessary one. Data Center Interconnects (DCI) Ethernet cable speeds increased from 100 Gb applications to 400 Gb and beyond. Server speeds have gone from 10 Gb to 25 Gb and beyond, with 100 Gb speeds on the horizon, and already in place in some data centers. 

The result is that data centers are now frequently operating like edge computing networks. Here is how it works. 


Key Takeaways

By the end of this article, you’ll know:

  • How Ethernet is optimized in power, reach, and latency.
  • How IPUs and edge computing centers address speed optimization of ethernet in data centers.
  • What is needed to facilitate deployment of IPUs and edge computing centers.

Optimizing Ethernet in Data Centers

There are four factors in optimizing data center ethernet use: speed, power, reach, and latency. Speed is already being enhanced and optimized by the creation of better and more modern cable designs. But for the other areas, there is still work to be done. 

Power

When it comes to power, many data centers have gone green, with their own renewable energy sources. In most cases, they have access to all the power they need. The key is to use it in the most efficient way possible. With more power comes the issue of design, including hot and cold aisle design choices and more. 

Reach

Data center architecture must take a holistic approach, whether you are starting from scratch with a new data center or making moves and changes to update its current infrastructure. Everything from switches and routers to transceivers and overall physical design, reach must be weighed by efficiency vs. cost.

Latency

Finally, latency is related to the final user experience. When it comes to gaming or video conferencing, low latency is the expectation, while when conducting internet searches, it’s not as critical, but can still be an issue for users. As speed increases and fast becomes the norm, latency expectations change with it. 

These three areas are critical to how ethernet is used in data centers, but it is far from the only one.

Infrastructure Processing Units

How we manage this need for speed is changing on the hardware and software side of things as well. Infrastructure Processing Units (IPUs) run Software Defined Networking (SDN) programs away from the server core. This saves critical server bandwidth, but it comes with an additional load cost. 

As these advances develop, the demand for new and better ethernet cables arises. And as ethernet cables advance, IPUs hardware and software applications evolve as well. Both improve in sync with the other. It’s a developing relationship, but one data center manager’s must take advantage of. 

Edge Computing Centers 

One solution to speed is to move the data center closer to the end user. This has been a developing trend, but increasingly data centers are expanding to distributed models where the interconnections between resources drive both power and speed, creating a better overall experience for the end user, and reducing latency. 

This comes with challenges. As edge computing rapidly becomes the norm, that latency KPI gets lower and lower. Low latency is key, and specifically, DCI applications are critical to meeting new standards. Ethernet connections are a vital part of this change and growth.

The Need for Speed

What’s needed to make all of this work? The first is optical transceivers, which allow data centers to make reductions in the power they use, but enables them to increase bit rates at the same time. This allows for the increase of speed in the leaf-spine connections, a critical component in any data center, but especially those that are hyperscaling. 

This does not come without challenges, as not all ethernet cables are created equally, and interoperability can become an issue. 

To help with this, high-speed breakout cables are often used. These cables have one end that supports the aggregate rate and the other end is a series of disaggregated interfaces. With their speed comes performance challenges, especially over distances. However, there has been some rapid development in this area. 

The New Normal

As 400 Gb speeds become the norm and data centers are increasingly on the edge, there are many advantages. Distributed networks mean easier disaster recovery and backup planning and create the ability to use shared resources to meet shifting demands. 

However, this creates some challenges with testing and maintaining KPIs. Interoperability remains a key component of successful deployments.

Edge Data Centers – Space and the Final Frontier

Edge of space - Edge Data Centers - Space and the Final Frontier - Cable Management Blog

Computing on the edge: it seems that everyone is doing it, from big industry to manufacturers, from ISPs to Cloud Computing centers. When you can locate computing and analytics power closer to machines connected via the IoT and other data sources, the faster you can gather data, and the more data you can store and analyze in a timely manner. For some, edge data centers seem like the final frontier for data.


Key Takeaways

By the end of this article, you’ll know:

  • The challenges faced by edge data centers.
  • The solutions for efficient space usage in edge data centers.
  • Economic impact of efficient space utilization.
Feature Edge Data Centers - Space and the Final Frontier - Cable Management Blog

This has resulted in data centers that vary in size, from the size of a very large cabinet to those contained in the space of a small shipping container. But like any journey to the edge, there are challenges and risks. There are two primary ones we will address here:

  • Temperature – Because of the small spaces edge data centers often occupy, airflow and temperature control can be tricky.
  • Space – Smaller size also means that saving space is critical, and on the flip side, can also enable more airflow and indirect cooling in a confined area.

In this way, the two primary challenges are related, and often a solution that mitigates one will also help mitigate the other. Let’s take a quick look at each of these.

Controlling the Environment on the Edge

The temperatures that edge data centers operate at are critical. And there is a huge difference between the cooling we need for a building designed to keep people comfortable, and a building designed to serve machines. Think of it this way: if someone opens the door to your office, you may feel a blast of warm or cold air, depending on the time of year. Your discomfort disappears quickly when the door closes, as the HVAC system takes over, and brings air back into the broad temperature tolerances humans can endure.

However, what happens when you go to an edge data center and open the door? The answer is, it depends on where it is. Large, brick and mortar data centers can be located in areas with minimal environmental challenges and low risk of natural disasters. But edge data centers must be located, well, where they are needed. That means in dusty and dirty environments, areas with extreme temperature fluctuations, and more.

There are really only two choices:

  • Develop and deploy equipment designed to withstand extremes, at a higher price point. A good example is cellular equipment like that developed by AT&T. However, the cost of this equipment is too high for standard edge data center deployment at scale.
  • Work with existing, readily available equipment and use unique strategies to combat environmental changes at a small scale, including using tents or shrouds for entry and exit, using handheld temperature and humidity monitors to evaluate current conditions, and developing strategic plans for unexpected events.

Another part of the solution is to use remote monitoring, AI and the IoT in edge data centers to mitigate the need for human intervention. Monitoring the health of equipment and preventing disaster in the first place is one of the keys to efficient management of edge data centers.

This is but one of the challenges data center managers face. The second is the efficient use of available space.

Saving Space

While cooling and environmental control are critical, so is the efficient use of space. This can result in increased airflow and easier HVAC solutions while also enabling more servers to be installed in the same amount of space.

This involves a few key steps:

  • Rack Selection – Whether a data center uses 23” or 19” racks, there are rack solutions that take up less space, and are also able to use better rack management options.
  • Cable Management – ZeroU horizontal cable managers makes more room for servers in a single rack, and they prevent the “spaghetti mess” that can happen in server racks, and be especially problematic in edge data centers that are more compact.
  • Compact Vertical Cable Management – 11U cable managers also save space and keep cables organized and easy to access should moves, changes, or repairs be needed.

Anything that can be done to save space in an edge data center makes facing the other challenges related to environmental control easier, but it also has another impact: an economic one. The less space you need to get the computing power you need, the more compact your data center can be. Alternatively, this can give you space to scale as needed without creating yet another data center space.

At the edge, there are always challenges, but there are also solutions. From controlling the environment in and around the data center to using the space in the most efficient way possible, with the right equipment, these obstacles can be transformed into opportunities to change not only how much data is collected and how quickly it can be acted upon, but where it happens as well.
