7 Considerations When Choosing Fiber Optic Cable

7-Considerations-When-Choosing-Fiber-Optic-Cable-Feature-Image

Fiber optic cable has become the go-to choice for a variety of applications by data center managers. The reasons are many, including advances in cable technology that make it an even better choice. But there are several things to consider when choosing fiber optic cable to ensure it’s the right fit for the application. Here are seven of the most important ones.

Choosing Fiber Optic Cable – Discover 7 Considerations

Distance

One of the big advantages of fiber optic cable is the loss factor: fiber only loses 3% of data over 100 meters compared to much greater losses with copper cables like CAT6 cables. While copper may be a great choice for short distances, the longer the cable needs to be, the bigger advantage to choosing fiber optic cable.

So the first factor to consider when choosing fiber optic cable is the distance the data must travel.

Interference

Fiber is fully resistant to interference from various sources like power lines, lightning storms, and even deliberate scrambling and disruption. So while the first consideration is how far the data must travel, the second consideration is where the data may travel. In data centers, whether cables are managed by running overhead or the less common instance of running through underfloor spaces, there can be sources of interference in or near that path.

This is also true in edge data centers, where everything is more compact and closer together. This is also true in modular data centers, and the right fiber cable can ensure that you can scale quickly and easily as needed. As we move toward collocation and hyper scaling, this becomes even more important.

Bandwidth

Data centers must be prepared for the future, and the bandwidth your cables can handle is a big part of that. For instance, the rise in the use of OM5 cables over OM3/4 especially in new builds is an indication that data centers are preparing for increased 5G and traffic from VR and AR applications.

This is essential to prepare for the coming 400G demands, especially in Edge data centers. As “work from home” or “work from anywhere” becomes the norm, even smaller residential data centers will be inundated with new traffic, as we saw through the COVID-19 pandemic. It seems that more companies are shifting to hybrid workforces, moving their corporate headquarters out of city center areas that are more expensive to rent, and even enabling partially or fully remote workforces.

Combine that with increases in “shopping from home” and multiple streaming devices, and speed and bandwidth are more important than ever.

Security

Of course, security is one of the top concerns for any data center. A single breach can put an entire company out of business, and result in serious issues if the data of thousands of customers is compromised. While most security issues are found in software and in the human factor (like compromised passwords) there is still a certain amount of risk in physical hardware.

However, fiber cables are difficult to compromise without the intrusion being detected, which means at the very least, using fiber cables, especially in areas where they could be potentially compromised physically, is a vital part of an overall data center security plan. Choosing the right cable in the right place can make the difference between protecting your data center’s security and digital assets, and a potentially costly data breach.

Cable Size

Over time, thinner fiber cables that carry as much data as their larger counterparts have been developed, making it practical to use fiber nearly anywhere. These thinner cables can also be bent and routed easily, saving space in your cable management systems.

Thinner cables also contribute to higher airflow and more efficient cooling, another potential area of cost savings. Fiber cables can also be bundled, organized, and labeled easily, preventing the spaghetti mess that often accumulates at the rear of server racks. Of course, this can also be prevented by having a better cable management plan in place.

In short, consider the size of cable you are using in any given area, and weigh that with other factors like distance, interference, and bandwidth.

Cost

Above, we mentioned OM5 being the future of fiber cables, but their wide adoption will come as they are produced in various lengths and sizes on a larger scale. This is because at the moment, they are produced to custom specifications. However, as OM3/4 are still viable and compatible with OM5, you can update your data center in incremental stages, and still utilize the less expensive OM3/4 cables as needed.

You’ll want to weigh cost against performance. Yes, OM5 is the best way to prepare for the future, but that can be done in cost-effective stages as your data center changes and grows. Replacing cables when you are doing moves and changes, or a new build will save you money in the long run.

Durability

Choosing fiber optic cable is easy when it comes to durability, as it’s an extremely durable cable for the most part. It is important that you evaluate where and how the cable is being used when choosing the proper cable. Where bends happen, and in an area where there may be more moves and changes than normal, you will want the most durable cable for that application.

Fiber comes in different diameters and insulation levels, and so you should be sure to choose the right one for that particular application. Evaluate several ways you can improve cable use to increase efficiency and scalability.

When choosing fiber optic cable that’s the best fit in any given application, be sure to take all of these factors into consideration. Need more information? You can check out some of the great information on our blog and in our various white papers, but if you still have questions, reach out to us. We’d love to start a conversation about how we can meet your data center cabling needs at any scale.

How to Prevent Data Center Downtime

Data center downtime is no joke. It can literally make the difference between a data center surviving and failing. And a new study by the Ponemon Institute shows that modern data centers and data centers at the edge are more susceptible to downtime than ever before. This is because data centers are much more complex than they ever have been. Most core data centers suffer 2.4 facility shutdowns per year, and some of those last around 138 minutes – more than two hours! Edge computing data centers experience twice as many shutdowns, but that average half the duration of core data center outages.

In addition, it is helpful to remember that although total facility failures occur with the least frequency, individual server or rack failures can also be costly, especially in Edge data centers, where every piece of equipment has some critical function.

At the outset it is also important that we define core data centers and edge data centers. Edge data centers are usually about ⅓ the size of their counterparts, although the term edge does not refer to size. Edge refers more to the data center location, generally closer to where the data center is needed to increase speed and response times, and save bandwidth.

Data Center Downtime

Conflicting Priorities

Data center managers are faced with decisions about efficiency, the transition to Net Zero carbon emissions, and avoiding redundancies whenever possible, but this also can leave them susceptible to downtime events if a problem occurs. This is illustrated by the causes of downtime: UPS battery failures, human error, equipment failures, other UPS equipment failures, and cyberattacks.

Respondents to the survey revealed that over half (54%) are not using best-practices, and that risks of data center downtime are increased because of cost concerns.

The Cost of Downtime

While cost concerns often increase the risk of downtime, the actual cost of downtime can be much greater. According to a 2014 survey by Gartner, facility downtime cost an average of nearly $5,600 per minute, or between $140,000 to over half a million dollars per hour depending on the organization size. These costs continue to rise, with more recent statistics from the Ponemon Institute survey mentioned above calculating average costs at nearly $9,000 per minute.

It’s more than just the money costs though. The real cost comes in reputation and customer service. Data centers that suffer above average downtime are much more likely to go bankrupt. Uptime is perhaps more critical than it ever has been, and customers remember problems far more easily than they remember reliable service over time.

So what do we do to prevent data center downtime?

How to Prevent Data Center Downtime

There are solutions to downtime issues, and many are known to data center managers. However, they are easier said than done. Here are a few of them:

  • Adopt best-practices – The fact that most data centers know they are not following best-practices reveals they know what to do, they are just not doing it.
  • Invest in new equipment – Equipment failures come in outdated equipment not up to the current needs of the data center. Replacing it is one of the easiest ways to reduce or eliminate downtime.
  • Improve your training – Be sure that all employees, both existing and new, are aware of best practices and what you expect of them on the job. Make training comprehensive and focus on outcomes and skills that build long-term success.
  • Improve your documentation – Your data center plans, including power, cabling, cable management plans, and others should be thoroughly documented and available to employees. If not, in the words of Captain Picard, “Make it so.”
  • Don’t fight redundancy – Redundancy is a good thing for the most part. You certainly don’t want to overdo it, but you do need to have contingency plans and equipment in case downtime does happen.

Of course, these solutions are simplified, nor are they always possible for data center managers to achieve with the resources they have available.

There is Room for Improvement

The takeaway from this data is twofold. First, data center downtime at these rates are unacceptable for most organizations. The second is that there are solutions, and there is plenty of room for improvement. Among the solutions mentioned above, there are some critical elements.

  • Redundancy – This has been preached from the beginning for both core and edge data centers, yet half of data centers have issues in this area. As a result, there is a trend toward more redundant equipment, especially at the edge, as large and small operations seek to better manage data center downtime.
  • Remote monitoring systems and AI – The other advancement that seeks to solve the issue of human error and detect equipment issues before they become a problem is remote monitoring and AI. Machine learning can help data center managers fix issues before downtime occurs, and helps them respond faster when a problem does occur.

Simply adding these two things can take data centers a long way toward greater uptime and more reliable service. After all, this is the goal of both core and edge computing.

Modular or Traditional Data Center Builds – Which is Better?

Modular or Traditional Data Center Build - Which is Better? Cable Management Blog

“The future of data centers is modular,” one popular website states. “The traditional data center is not dead,” says another. Who is right? What is the future of data centers? Is one better than the other, and if so, why?

Here are some pros and cons, and some potential answers data center managers might want to consider. 

Jump to Section:

Modular and Traditional Data Center

Modular vs. Traditional Data Center PUE

One of the first things we talk about with modular or traditional data centers is PUE, or Power Usage Efficiency. Most of the time, modular data centers have a lower PUE. However, there is a cost associated with that number.

Traditional data center builds often have a higher PUE initially because there is space for expansion and adding additional equipment. This can sometimes come with higher HVAC and other costs until the data center is at capacity and running at maximum efficiency. We’ll talk about that factor more in a moment. 

For modular data centers, because they are constructed with tight specifications and already at an efficient capacity per module, the PUE is lower from the start. All components are easily matched, and compact spaces are easier to control when it comes to cooling, humidity, and other factors.

What is the downside? When a brick and mortar data center is up and running at capacity and the design has been well executed, PUE levels can be similar, and it can be much simpler to make moves and changes without additional modules and construction. 

Security

As with PUE, there are two sides to this coin. The modular data center can be easier to secure, as they are more compact and self-contained. When installed behind a secure barrier with video and other surveillance measures, the physical security of a modular data center can be assured.

The flip side? Modular data centers may evolve and require additions over time, meaning the physical space will also have to be modified. Proper planning can mitigate this issue, but a traditional data center build can be easier to manage from this perspective, with security built into the construction itself, along with remote monitoring and other security features that must be handled differently with modular data centers. 

The argument over which is better can go either way, but the permanence of a traditional data center build often wins out when it comes to security discussions.

Modular vs. Traditional Real Estate

When locating a data center, we have talked about things like accessibility to a green power grid, the ability to construct your own green energy backups, and more. Real Estate that satisfies all of those requirements can be hard to find, and prices reflect that premium. 

So in this case, the more compact modular data center build has some distinct advantages. The less real estate you need, the less initial costs will be to purchase (or lease) space for the data center. This also has an impact on another factor: the cost of the build. 

Building Costs

Constructing a modular data center is much cheaper than constructing a traditional one, effectively 30% less. That is a huge number when you talk about initial costs. Combined with the lower cost of real estate, deploying a modular data center is much more efficient for those looking towards hyperscaling and co-location. 

This has been shown to be especially true as more “work from anywhere” options become available, and the need for high-speed data center capacity shifts from city centers and similar areas to residential and suburban ones.  

This leads us to our next advantage:

Deployment Speed

The time needed to construct a traditional data center is much greater than that needed to deploy a modular data center. The average data center takes 18-24 months from start to finish, but you can save around 30% of that time by going the modular data center route.

In part, this is because you avoid traditional construction delays due to bad weather, seasonal construction, and more.  

This is not to say modular deployment is better – it is simply faster. It could be argued that a traditional build will last longer and the overall construction will be of higher quality, but that is not always the case. Many modular data centers are created with a similar lifespan in mind and can last just as long as a traditional build.

So which one is better?

The bottom line when it comes to which one is better, a modular or traditional data center build, the answer is, it depends. Ask these questions:

  • How urgent is the need for this data center? 
  • Where will the data center be located? What is the costs associated with a greater holding of real estate?
  • What is the purpose of this data center? Is the need for moves and changes anticipated?
  • What kind of security is needed, and what is possible in the data center location?
  • What is the long-term plan for this data center?

The answers in your situation may vary, but as much as the traditional data center is not dead, the modular data center is on the rise, and for many situations, it’s the best option. 

No matter whether you are creating a modular data center or doing a traditional build, your rack and cable management matter, as does your labeling system and your physical layer security.

4 Steps to Prepare Your Data Center for Net Zero Carbon Emissions

4 Steps to Prepare Your Data Center for Net Zero Carbon Emissions - AnD Cable Management Blog

The race to net zero carbon emissions is on – our economy and our world depend on it. The data center industry, one that tends to gobble up lots of power is at the forefront of a number of initiatives being implemented around the world. How will you prepare your data center for net zero carbon emissions? Here’s 4 steps that will get you started.

Jump to Section:

4 Steps to Prepare Your Data Center for Net Zero Carbon Emissions - AnD Cable Management Blog

The Situation Now

Data centers first became the focus of Greenpeace and other groups back in the mid-to-early 2010 boom. The focus at that time was on enterprise-level data centers – the big guys, in other words. The fact that data centers used lots of power became evident and so the move toward minimizing that impact grew in both urgency and popularity.

So much so that the position of Chief Sustainability Officer (CSO) grew to overtake the emerging position of Chief Security Officers. Those in charge of cybersecurity ended up having to change their title to CISO (Chief Information Security Officer) because CSO had already been widely recognized.

Since then, smaller edge computing data centers have become the new focus. With COVID hastening the transition, today, cloud computing, AI, remote monitoring and other data center management trends have now established a level of control and sustainability not previously thought possible.

Thanks in part to these technological developments, net zero carbon emissions now feels more achievable and less like the plot-line in a futuristic sci-fi flick. So, in what areas of the data center can emissions be reduced?

Step One – Make a Commitment

There are several individual measures that promote sustainability. The key is to take all of those individual components and standards and work them into an ecosystem that supports your emissions goal.

Companies and countries alike are making a commitment to reducing carbon emissions as a part of their brand. However, words are not enough, and these companies – including the largest hyperscaling data center companies in the world – are taking action. Advances are happening quickly in the area of artificial intelligence (AI), remote management and data center design. Being on the leading edge of these developments shows that your data center is part of this commitment to a “greener cloud infrastructure.”

Like most strategies, it’s only once a firm commitment at the top of the organization has been made that the necessary actions can be taken, including providing leaders with the authority to make decisions that align with the goal and that resources, responsibilities and accountabilities are allocated.

Step Two – Use Sustainable Energy Sources

Solar, wind and even hydroelectric power are all sustainable sources of power that can make dependence on coal and other carbon-intense fuels a thing of the past. Companies like Tesla and Microsoft are testing and deploying battery technology that can run data centers longer than ever before, even with no sun or wind available.

This means only using the local grid as your primary power source if sustainable energy is available 24+7. Otherwise, the data center will need to provide at least some sustainable sources of its own, like a solar or wind farm designed to directly support a data center.

Because this is expensive, only the largest, hyperscale companies with large data centers can be 100% self-sufficient. Hybrid solutions could help to bridge the gap, such as supplementing local power supplies with solar and wind on site. Selecting a site that’s close to a local, sustainable power grid should be a factor in choosing where to locate your data center and will support the goal of net zero carbon emissions.

Step Three – Operate at Peak Efficiency

For data centers, not only should your power be sourced responsibly, but your data center needs to operate efficiently. One way to reduce carbon dependency is to simply use less power. Strategies can include initiatives such as pro-active device monitoring to identify ‘Zombie Servers’ – stacks that contribute little to performance, but still use significant resources to maintain.

The efficient and responsible use of power, as covered by the United Nations Sustainable Development Goal 12, is about Responsible Production and Consumption. Some other standards include:

  • PUE (Power Use Effectiveness) – Determined by dividing the power coming into the data center by the power used by the computer infrastructure.
  • LEED (Leadership in Energy & Environmental Design) – A green building certification program that rates building design
  • PAR4 – A new form of power measurement that accurately measures IT equipment power usage to help optimally plan for capacity.
  • ASHRAE (The American Society of Heating, Refrigerating and Air-Conditioning Engineers) – Standards for the temperature and humidity operating ranges for IT equipment and data centers.
  • CCF (Cooling Capacity Factor) – CCF is a metric used to evaluate rated cooling capacity against how that capacity is actually used.

These standards are just a few of those used to rate the efficiency of a data center and are designed to help data centers move toward net zero through more effective use of the power they have available.

Step Four – Build-in Resilience and Agility

The real job of a data center is uptime. Yes, customers want a green data center that is moving toward, if not already achieving, net zero emissions. However, at the same time, they expect that there will be no reduction in service. They expect full uptime, speed, and data protection.

This means that systems must not only be green, but must be reliable and include redundancies, power backups, and other protections, including cybersecurity and physical layer security to protect both customer assets and their data.

The good news is that not only is clean energy better for the environment, but it is also more reliable in many cases, allowing data centers to keep uptime near 99.999% standards. This is a balance that sustainable data centers must constantly monitor, adjust to and plan for.

Net zero carbon emissions is the standard of the future. Your data center can prepare now. Use clean energy, and plan to scale with that energy use in mind. Use the energy you have efficiently and plan for resiliency as part of your transition strategy. It’s what clients and customers and the world deserves.
