The Spaghetti Mess – Rack Cable Management Essentials

The Spaghetti Mess – Rack Cable Management Essentials - AnD Cable Management Blog

We often talk about the importance of network cable management in data centers, and how important it is to efficiency, airflow, equipment longevity, and more. But what about on managing cables on the rack itself? 

Key Points

-The Server Rack Itself: A sturdy, properly sized server rack is the foundation of a good cable management system. Wider racks are becoming more common to accommodate larger components.

-Cable Managers, Bundling, and Labeling: Using tools like horizontal lacing bars, bundling cables with Velcro ties, and clearly labeling them are crucial for organization, reducing interference, and simplifying troubleshooting.

-Planning and Proper Cable Length: The most important element is having a detailed plan. This includes determining the number of racks and managers needed and ensuring cables are cut to the appropriate length to avoid tangling and data failures.

Do your racks have a ‘Spaghetti Mess’ of cables?

In fact, we know (because you’ve told us) that nearly everyone has encountered the “spaghetti mess” at some point or another. This is a bad thing, not just because of how it looks, but because of the possible damage, lack of efficiency, and even increased maintenance costs.

But there are solutions, and if you understand the essentials of rack cable management, things can be pretty simple for you. You don’t ever have to look at the “spaghetti mess” in your data center again. 

Let’s start at the beginning: 

The Server Rack Itself

First of all, we all know there are different kinds of racks and different sizes. While improving technology means some things are getting smaller, server components are actually getting larger. That means that wider racks, on the order of 23” cable racks or wider are more common. You can’t use a 19” cable rack for a 23” component. The end result will not only be ugly but could be disastrous.

In addition, racks, specifically in California but in other locations as well, must be built to withstand earthquakes and other natural disasters. It’s a pretty major requirement, and even if you aren’t in California, there may be state or local ordinances that cover the kind of racks you can use in your data center. The rack is the foundation for a good rack cable management system.

Racks also come in different levels of quality. Always remember that cheap is probably cheap for a reason. You want racks to not only be the right size, but to be sturdy and reliable. Cheap racks that bend, fit together poorly, and that don’t work well with standard adapters and rack cable managers will end up costing you more in the long run. Make sure you have the right rack for the right job. 

Rack Cable Managers

Rack cable managers, sometimes called horizontal lacing bars, are a critical part of cable management. There are a number of varieties, both horizontal and vertical. They are often classified by the amount of space they take up on the rack. 

Horizontal Zero U Cable Management Server Rack – 23″

For example, our ZeroU rack cable management systems doesn’t take up any rack space, allowing you to be more efficient with the use of your space, reducing the overall footprint of your servers. This means using fewer racks and leaving more space for airflow. 

A good rack cable management system also gives installers and maintenance personnel space to work. They have room to get tools and their hands in where needed, meaning they can work faster and more efficiently. 

Bundling and Labeling

Bundling like cables together keeps your racks looking neat, avoiding the spaghetti mess look. But it does more than that. Running like cables together reduces electromagnetic interference, makes finding what you are looking for easier, and again reduces maintenance time. 

Bundling can be done with zip ties, and while sometimes that is appropriate, most often Velcro is a better solution. It’s reusable, can be loosened or tightened as needed when doing adds, moves, and changes. 

QuickPinch Cable Labels

The other important essential? Labeling. When was the last time you thought, “I wish I (or someone else) had labeled that?” When troubleshooting and executing repairs, a simple label can reduce the time needed to sort through cables exponentially. Also, if you properly and accurately label cables, you are less likely to forget where they should be terminated. They are less likely to get tangled as you install them, allowing you to avoid the spaghetti mess.

Cable Length and Rack Cable Management

Another simple way to avoid the Spaghetti mess? Be sure your cables are cut to the right length and terminate them appropriately. Network cables that are too long are much more likely to tangle or get wrapped around one another. 

The key is simply following the old carpenter’s rule: measure twice, cut once. You don’t want cables to be too short either. This can result in sharp bends and even breakage, and those things can result in data slowdowns or worse, failures.

Have a Rack Cable Management Plan

What is the most important element of efficient rack cable management and avoiding the spaghetti mess? Having a plan and having everything on hand that you need. Whether you are renovating and updating your data center, building a new one, or replacing old components, develop a plan.

  • How Many? – Determine the size and number of racks you will need and order them ahead of time. 
  • Plan Ahead – Develop a plan to manage cables and order the horizontal rack managers you will need – and vertical racks!
  • Network Cable Requirements – Determine the amount of cable and the type you will need. Order them ahead of time, but also make sure you have the terminals you will need on hand. 
  • Velcro! Need we say it again? – Make sure you have more than enough Velcro cable ties on hand to bundle cables as needed. 
  • Colored Zip Ties – While not always the best solution (see Velcro) overall, zip ties still have their place in rack cable management. Have plenty on hand to aid with cable routing. 
  • Cable Labels – have plenty of custom labels on hand and use them. Make sure every installer is on the same page as far as the way things will be labelled. 

A plan will keep the spaghetti mess from developing in the first place, saving you hours later on.

FAQs

Why is proper cable management important?

Proper cable management improves a system’s efficiency, prevents overheating by ensuring proper airflow, simplifies troubleshooting and maintenance, and reduces the risk of downtime caused by tangled or damaged cables.

What is the best way to label cables?

It’s recommended to label both ends of each cable. You can use a consistent labeling system with clear, easy-to-read labels. Some professionals also use color-coding to differentiate between various cable types, such as power and data cables.

What is the most important rule for cable management?

The most crucial rule is to plan your layout and cable runs before you begin. This involves determining where power and data cables will be routed, selecting the correct cable lengths, and considering future growth.

Should I use zip ties or Velcro straps?

While zip ties can be used for more permanent connections, Velcro straps are generally preferred for rack cable management. They are reusable, won’t pinch or damage the cables, and allow for easy adjustments when adding or removing equipment.

How can I improve airflow in my rack?

To improve airflow, make sure cables are neatly bundled and not blocking vents. Use cable management accessories like horizontal and vertical managers to route cables along the sides of the rack, keeping the central area clear. You should also ensure that unused rack spaces are filled with blanking plates.

How Cable Management and Airflow Management Impact Each Other in Data Centers

How Cable Management and Airflow Management Impact Each Other - Cable Management Blog

Here’s the simple truth of the matter. Cable management can impact airflow management , and airflow should definitely inform the method, type, and execution of cable management. To understand how the two impact each other and what the best overall solution will be for your data center, it is important for use to take a look at cable management and airflow from a high level perspective.

Key Points

–Integrated Design is Crucial: Airflow and cable management should be planned together as a single, integrated part of a data center’s design to prevent issues like increased costs, equipment failures, and downtime.

–Poor Cable Management Impedes Airflow: Incorrectly bundled cables (e.g., with zip ties) can act as a physical barrier, disrupting the separation of supply and return air. This leads to lower fan efficiency, higher HVAC costs, and potential equipment damage.

–Proper Management Improves Efficiency: Research has shown that disorganized cables can increase component temperatures by up to nine degrees. Using tools like ZeroU rack cable managers and chimney cabinets ensures proper air intake and egress, which is critical for maintaining equipment health and energy efficiency.

How Cable Management and Airflow Management Impact Each Other
Airflow is an Important Factor in Data Centers

The Goal of Airflow Management

So what is the goal of airflow management? The goals are twofold: preventing large variations in air temperature and air pressure. This means separating supply air mass and return air mass through design.

Just grouping cables together with a zip tie does nothing to facilitate this and can actually result in a seridisruption of airflow. What happens as a result? Lower fan efficiency, higher HVAC costs, potential changes in pressure, and even equipment damage or failure.

The current problem? Because more people are working from home or adopting the work from anywhere culture as a result of COVID, data centers are having to increase capacity, and they may not have additional floorspace to accommodate more server racks. Since conventional cable management can use up as much as 25% of rack space, this means that intelligently designed rack cable management is more important than ever.

Because of this it is important that cable management and airflow be looked at as an entire package. There are two areas of cable management in a data center: cable management in the room itself, essentially the cables that run between server racks, and rack cable management.

Cable Management in the Room

Of course, we must manage the cables that run between server racks, and they have to go somewhere. There are essentially two approaches, and both can create unique issues. They are running cables under the floor or running cables overhead.

Perhaps the most common is underfloor cabling where the underfloor space is also used for cool air transport. This is usually a very efficient method for separating supply and return air masses. However. When you put more holes in the floor, say to accommodate more server racks, the risk of “bypass air” or mixing the two airflows increases.

Why not just go with overhead cable management then? In some cases, this works exceptionally well, although there are budget and logistical obstacles. The height of the cable pathway is also often an issue.

Think of it this way. If your data center uses the underfloor space for air system management and not cable management, overhead pathways are fine. If they are placed too high though, the warm return air underneath can actually get too turbulent, resulting in a mix of the supply and return air. This created a temperature bypass.

But this bypass also can increase variations in pressure throughout the data center, causing the fans and other mechanisms to work harder. It’s a delicate balance.

Rack Cable Management

There are a lot of best practices and industry standards for airflow and cable management between servers, but often rack cable management falls into the “out of sight, out of mind” category. That’s a mistake, as cable management at this critical point can have a huge impact on airflow management.

While this seems like it should be common sense, the practice of good rack cable management seems to be hit or miss. As early as 2002, research done by Paul Artman, David Moss and Greg Bennett (Dell PowerEdge 1650: Rack Impacts on Cooling of High Density Servers) showed that poorly bundled cables, overloading cables on a horizontal lacing bar (particularly 1U configurations) could result in as much as a nine degree increase in component temperature.

This is a good argument for ZeroU rack cable managers and other more advanced techniques. Also, more data centers are moving to 23” or larger racks as opposed to the standard 19” racks, because equipment manufacturers are constantly increasing the computing power per U space. As a result there are more cables per rack. As cable bundles get larger, they also need more space between them to increase airflow.

For some components that possess a single fan intake side and hot-switchable components on the other, there is really only one path for cables to go. Careful cable management means not only ensuring that the fan intake is not blocked, but that there is an airflow egress as well. Often specialized chimney cabinets that allow air to enter both the front and the rear of the cabinet can be used for these applications.

The Effect of Poor Cable Management

Poor cable management, whether cables between server racks or rack cable management, will negatively impact airflow management. More than just the increased costs associated with HVAC systems, poor airflow can also lead to premature equipment and cable failures, overheating, and even increased downtime.

5 Ways Effective Cable Management Benefits Your Data Center - Cable Management Blog
A ‘Spaghetti Mess’ of cables blocks network rack airflow very effectively!

Since uptime is the most important metric to most data centers, cable management solutions need to be an integral part of any planned data center and prioritized expansion.

Devising a Comprehensive Solution

What’s the solution? The best path is to be proactive rather than reactive. Plan airflow management and cable management together as part of an overall data center plan. Be sure you and your staff have the right tools and materials. This not only includes the right racks and rack cable management tools like ZeroU rack managers and chimney racks where needed, but things like Velcro, wire tags, and even colored zip ties to keep things organized.

If you do have to do a sudden expansion due to increases in demands, bring in the whole team and listen to everyone’s ideas. Use industry best practices where possible, but understand that creative solutions and innovation may be necessary in extraordinary times.

What is the most important first step to effective cable management?

The first and most important step is to proactively plan for cable and airflow management as an integrated part of a data center’s design, rather than reacting to problems after they occur.

Why is proper cable management so critical for a data center?

Poorly managed cables can create a “spaghetti mess” that blocks airflow, leading to lower fan efficiency, higher HVAC costs, and potential equipment damage from overheating. It can also lead to premature equipment and cable failures and increased downtime.

What are some common mistakes to avoid in data center cable management?

Common mistakes include using tight zip ties that can damage cables, not using blanking panels to prevent air recirculation, and not using cable management accessories like trays and clips to organize cables and allow for proper airflow.

How do cable management and airflow management relate to each other?

Effective cable management is a critical contributor to effective airflow management. By keeping cables organized and out of the way, you can ensure that cool air gets to the equipment and hot air can be properly exhausted, preventing them from mixing.

What tools or methods can help with effective cable management?

Effective management involves using solutions like ZeroU rack cable managers and specialized chimney cabinets. It also includes using appropriate fasteners like Velcro ties instead of plastic zip ties, and implementing a consistent labeling protocol for all cables.

The Impact on Data Center Services – Before and After COVID

The Impact on Data Center Services - Before and After Covid - Cable Management Blog

The COVID pandemic has impacted nearly every industry, and while some have been impacted negatively, others are thriving. The key to all of these things is the ability to adapt. Nowhere is this truer than in data centers. The impact of COVID on data center services has been significant, and those in this “essential industry” can’t work remotely for the most part.

Key Points

–Increased Demand: The global shift to remote work, virtual learning, and online entertainment during the pandemic caused a massive surge in internet traffic and the use of digital services. This led to a significant increase in demand for data center services, including cloud computing and data storage.

–Accelerated Digital Transformation: The pandemic acted as a catalyst for digital transformation efforts across many industries. Companies that had been slow to adopt cloud-based solutions were forced to accelerate their move to the cloud to support remote operations and meet changing consumer demands.

–Operational and Supply Chain Challenges: While demand for data center services soared, operators faced new challenges. They had to implement strict health and safety protocols to protect on-site staff, which sometimes included creating reserve teams and limiting access to facilities. Additionally, the pandemic caused disruptions in the global supply chain, which could lead to delays in the construction and maintenance of data centers.

The Impact on Data Center Services - Before and After Covid - Cable Management Blog
The Impact on Data Center Services – Before and After Covid

The truth is, troubled industries like airlines, hotels, travel sites, and restaurants were not huge consumers anyway.

“The upside cases are actually higher than any of the drawdowns coming in from the troubled sectors,” said Sami Badri, Senior Equity Analyst at Credit Suisse said during a CAPRE presentation. “These troubled sectors were not big customers in the first place, whereas the newer industries that represent a large cash flow stream for data center services are flexing even larger than they ever have before. This is creating a new high-tide environment for demand for the overall tech sector.”

While the financial impact has been positive overall, it has created an increased demand, which has an direct impact on what data centers are and how they operate. What has that impact been, and what are data centers doing about it?

Increased Demand in Unusual Places

“Almost as soon as lockdown started,” David Issel, the asset manager at a Comcast data center known as a “headend” told us, “this place was running at 95%. Fans and our HVAC system was at capacity.”

The Work from Home or rather Work from Anywhere demands of COVID have increased the need for residential reliability and speed on a larger scale. What was evenings of surfing and streaming are now days filled with workers tethered to their home offices, computers, standing desks, and dependent on their routers and home WiFi in ways we never would have thought of in January of 2020.

Data Centers Services have been quick to respond and increase capacity. “Even though the components are getting smaller, the units themselves are getting larger,” Issel told us. “We’re using 23” racks instead of 19” racks, and that means it’s more important than ever to conserve space.”

The other issue? It takes people to add hardware and capacity to a data center, but only so many people can be present in the facility and still remain socially distanced and adhering to mask requirements. Keeping employees safe is a top priority.

Changing Attitude in Lagging Industries

“Some industries have never been well architected to handle work from home or organize a virtual workforce,” Badri told us. “Three of those sectors are healthcare, government and education. We’ve been hearing that government IT spending pledges alone are up more than 20 percent. Education budgets are also increasing and shifting up. Other categories playing catch-up include healthcare, which has been a very big pain point for the U.S.”

This includes things like telemedicine, schools that are either operating 100% virtually or at least offering distance options to students and parents alike. Higher education is struggling the most, as universities train staff, shift to online platforms, and prepare for an entirely new education platform.

While even the Federal government has been lagging in using technology, local, regional, and state governments find themselves even further behind. The question is whether these industries will continue to advance digitally or whether, as the impact of COVID inevitably recedes, the demand will recede with it.

The Need for Speed

Consumers and others often confuse bandwidth and speed. However, there is a need for both, as more people are online at the same time than under normal circumstances. This is bandwidth, or the capacity of the network to handle volume.

Speed is about how fast data can be delivered. Both are vital for consumers. Imagine a neighborhood populated with day traders whose income can be impacted by millisecond delays. That same neighborhood might be filled with school children doing school work online during work hours.

For data centers and companies like Comcast and other internet providers, it is about the ability to scale. “We’ve got plans for getting ahead, and we’re working on expanding HVAC and capacity,” David Issel told us about his particular headend.

This need for speed may mean that new data centers and headends need to be built in order for companies to keep up.

Coming 5G and Other Advancements

A digital revolution and a move to more remote operations, companies like Zoom, Slack, and other communication platforms were things many thought would take years to manifest. Due to COVID, this digital revolution has manifested in months instead.

But there was already a revolution on the horizon. The 5G and IoT revolution was already putting pressure on data centers to adapt and be ready for a new, faster normal. 5G is about more than just speed though. It makes a data center more flexible in more ways.

“The flexibility includes things such as the desegregation of the control and user plains of the network and also migration towards distributed baseband processing and the radio access network (RAN). In turn, this leads to opportunities for virtualization of RAN network functions and it enables the convergence of the RAN into the data center space,” Mike Wolfe, Vice President of Wireless Network Engineering at CommScope explained in a recent DCD article, How 5G will Affect the Structure of Data Centers?

“What this means is there could be a lot of smaller data centers, distributed geographically in such a way that’s going to make them a little bit more difficult to manage. Connectivity will be important in terms of how we do that,” Jamie Birdnow, also of CommScope shared in the webinar.

While it is safe to say that data center services will require huge changes to accommodate and enable 5G, there is still a lot that is unknown.

For example, we don’t know is how applications are likely to develop over a number of. Some things will not evolve as expected, and there are surprises. Autonomous cars will require far more sophistication than remote surgeries.

The key is to understand that data centers were already in a state of change, and the COVID crisis has only accelerated that.

The Bottom Line in Data Center Services

The data center industry has experienced a focus shift due to COVID, and as with any revolution during a crisis, it comes with challenges. That means the efficient use of space, the expansion of capacity more rapidly than planned, and employing other techniques to “future proof” data center services.

Virtual connectivity is a must,” Badri told us. “It’s no longer a debate. It’s now a case of survival and relevance and productivity. You’re starting to see permanent shifts.”

That speaks back to David Issel and Comcast, not only scrambling to catch up and expand, but to prepare for whatever tomorrow may bring.

A key to Issel’s success is his partnership with Louis and AnD Cable Products. Not only does his data center depend on their products and reliability, but they’ve also worked together to create custom hardware that is “perfect for the application,” Issel told us.

It’s these types of cooperation and efficiency, like the ZeroU Horizontal Cable Managers AnD Cable Products offers, which allow technicians to work more easily, increase the life of cables, and more.

If you want to “future proof” your data center services and you are looking for a physical hardware supplier that will be there for you as you expand and adapt, contact us at AnD Cable Products today. We’d love to talk about how we can best work together.

5 Ways Effective Cable Management Benefits Your Data Center

5 Ways Effective Cable Management Benefits Your Data Center - Cable Management Blog

It’s easy for computer cabling to get out of control – even at your office desk disorganized cables can be a problem! So, when it comes to the many tens or even hundreds of servers in a data center, cable management is clearly an important element to get right.

Congested and disorganized cabling can quickly lead to a “spaghetti mess.” Not only is this ugly, but it can be the cause of some serious problems. Here are five reasons you should avoid cabling congestion, and how effective cable management can minimize risk and benefit your data center.

5 Ways Effective Cable Management Benefits Your Data Center - Cable Management Blog
Congested and disorganized cabling can quickly lead to a “spaghetti mess”

1. Avoiding Downtime / Outages

One of the primary reasons for effective cable management is to reduce the risk of downtime. This is especially true when someone is working on making additions, expanding capacity or repairing existing systems.

Effective cable management allows technicians to simply unplug and plug in cables that are necessary to the action they are taking. Disorganized cables may involve “troubleshooting” steps that really involve determining what is plugged into what before work can begin.

Since you’re often paying by the hour, and all that plugging and unplugging can cause costly downtime / outages, organized cables are really a necessity in any data center environment.

2. Workplace Safety

What’s one of the things your servers need to avoid future issues? Airflow. Effective airflow prevents overheating, fire hazards and even cable breakage that can cause serious issues – or at worst, an outage.

Cables that are too long and disorganized can also quite simply be a tripping hazard, increasing the risk of workplace injuries. In addition, there is a risk of electric shock. Want to keep your employees, workplace and servers safe? Avoid cable congestion and improve your cable management.

3. Future Expansion

You are planning to expand and modernize your data center over time, right? With the internet of things, the rise of VR and AR applications, and even the adoption of 5G networks, speed has become ever more critical, and will continue to be so over time. That means you need to have the ability to add to your server stacks quickly and easily.

But congested cabling can make this problematic. You’ll have to untangle and organize what you have before you can safely add more. A simplified, organized and effective cable management system is an important element of IT infrastructure scalability, and will make future expansion that much easier.

4. Lookin’ Good

You know what else congested cabling does? It looks bad! Imagine a client visits your office and sees a mess like the one pictured above. What will they think of the rest of your company if your cabling is that disorganized?

You never know what will impress or not impress a potential client, and to be professional in every aspect of the appearance of your business is essential. If it doesn’t look good to you, it definitely won’t look good to your clients.

5. Show Me the Money!

The above are all great, but how are you going to sell better cable management to your CFO? In the long run, great cable management WILL save you money. Your business will run more smoothly, you’ll have fewer outages, less maintenance and repairs and expansions will be quicker and easier.

For many businesses, especially in a time when more and more is being done online, a reliable data center is at the heart and soul of staying in business – and a vital key to profitability. Better cable management is also a cost effective way to improve the bottom line, with benefits continuing to roll in over time.

Effective Cable Management Made Easier

Fortunately, it’s easy to see the advantages of a simpler, cleaner cabling system. Instead of the nightmare of having multiple wiring systems in place, especially when many devices are being used at the same time, a more structured cable management system will make it easier to access and work on each component.

IT Infrastructure and Business Continuity

IT Infrastructure and Business Continuity - A150 Physical Layer Network Security - Cable Management Blog

If there is one thing that is certain in the current environment, it’s uncertainty. From COVID 19 to unprecedented racial tensions and unemployment crisis, we are facing a fluctuating and unpredictable economic recovery. These factors are affecting every single business, and business continuity across many sectors.

Business continuity can be disrupted by any number of events and preparing for them is often called “Black Swan” planning, disaster planning, or at its most basic, unexpected event planning. Anything from natural disaster to personal issues that disrupt the best of plans can be considered a threat to business continuity. IT infrastructure is critical to maintaining that continuity, from cashflow strategies to the protection of data. The right decisions when it comes to technology can be the difference between success and failure.

IT Infrastructure and Business Continuity - A150 Physical Layer Network Security - Cable Management Blog

IT Infrastructure and Cashflow

For many businesses, their data is their business. When it comes to data centers, it is the only thing that keeps them going. But how does the right infrastructure help with cashflow?

  • Optimized Use of Space: Real estate costs money and using the right physical racks and cable managers means servers take up less room.
  • Flexibility: One of the keys to business survival at times like these is flexibility. Being able to shift the application or data and to lock down and suspend use of non-critical assets is vital.
  • Increased ROI: While some businesses will struggle, others will shift and have critical projects that must be prioritized. This is a great way to increase ROI in challenging circumstances.
  • Process optimization: Not only does your hardware need to be configured correctly, but your processes should be streamlined and as efficient as possible

The more efficient your IT physical layer and software performs, the greater your cost savings will be, and the more easily you can stabilize cashflow.

Adapting to New Ways of Working

If you had told anyone that the new way of working would be remote for the majority of employees in 2020, many would never have suspected that big companies like Google, Twitter, and Facebook would be transitioning their workforces to work from home scenarios. However, the new reality means just that.

Not only are companies seeing increased efficiency, but they are also seeing cost savings from workplace infrastructure to the coffee pods in the break room that seem to never run dry now.

But a remote workforce creates IT challenges. Remote access to servers requires a new level of security both virtual and physical. Employees need secure VPN logins they can access from nearly any Wi-Fi connection, ways to secure and protect equipment they use remotely, and more.

Since Work from Home can include work from virtually anywhere, these factors have come front and center to the IT world. Devices from laptops to apps installed on personal phones and tablets can all be keys to a productive remote workforce. Physical items like privacy screen protectors and places to secure company devices when not in use are key. Off-site data and equipment security is a vital part of the “new business normal.”

Physical Layer Network Security

A common concern for IT personnel is the security of their remote sites. Even offices, as more employees transition to a work from home environment, will no longer have personnel standing by to “keep an eye on things.” This brings up the real value of remote monitoring.

The diagram above describes simply the way a remote physical layer network security monitoring system would work. Sensors and cameras would be deployed depending on the needs of the facility, and the data would be sent to a controller. This data could then be monitored by nearly any devices with an internet connection.

Everything in the environment could be monitored, including:

  • Humidity
  • Temperature
  • The presence of water
  • Power usage
  • Server tampering or movement
  • Server room doors and entry points
  • AC Unit Status

And more. All of these factors trigger remote alerts and even physical alerts like sirens or light alarms on site. This ensures that data centers and servers are monitored even from a distance, and various items can be controlled from that same application, allowing the user to take action on the data they receive.

Without physical security, the usefulness of IT for continued business continuity is clearly threatened. “We basically work the same way as home security systems, but for business IT,” says Jumie Yuventi, VP Product Management of the A150 Physical Layer Network Security system. “Data center management platforms take the responsibility of 24×7 real time monitoring, warning notifications (by emails and /or SMS), data analysis and data archiving, so IT and facility managers can sleep better at night knowing A150 is keeping an eye on everything.”

The New Digital Outreach

You can be doing everything in your power to ensure data security both on and off site, and you can be doing your best to create opportunities to stabilize your cashflow and keep your business working.

But how do you communicate these things? The days of a simple meeting in a conference room with a slide presentation are now gone, and remote digital selling has taken its place. This means that not only do you have to communicate the new way things are working to your employees and internal partners, but to your customers and clients as well.

Consumers want to know now, more than ever, that you can be trusted with their data, that you are doing everything to make sure it is secure, and that your employees are safeguarding your data at all times.

The shift to remote selling, remote working, and remote monitoring has brought about changes that will affect nearly every business for years to come. To ensure business continuity, you must adapt and evolve with the changing times. Tools like efficient cable management and physical security are an important part of that process.

4 Cable Improvements That Increase Data Center Efficiency and Build Scalability

4 Cable Improvements That Increase Data Center Efficiency and Build Scalability

The data center of the future is needed now. Added to rising growth in a world lived increasingly online, augmented reality (AR), virtual reality (VR) and 5G are driving greater demand for data speed and volume. How can you ensure your data center is operating at peak performance now – and has the capacity to sustain performance as demand grows? Building for scalability is the key. Fortunately, those elements that create data center efficiency now lay the groundwork for your ability to respond well in the future.

4 Cable Improvements That Increase Data Center Efficiency and Build Scalability

Building Data Center Efficiency

When we talk about scalability in data centers, we are actually talking about two different things. The first is the physical layer, which includes new data servers, switches, storage devices and cable managers. By optimizing server rack space and ensuring effective network cable management, efficiency and uptime can be improved, reducing the footprint required for server hardware and lowering equipment costs.

The second, and more complex, is the infrastructure that supports increasing data rates and volumes. With AR, VR, 5G and the IoT demanding data rates and speeds never seen before, data centers need to respond strategically to remain competitive. Given the escalating growth rate, it’s safe to say that decisions made today will have a dramatic impact on capacity to deliver unprecedented volumes of data, both in and out. For peak data center efficiency, you need to be dense (physical), fast (the right cabling), and cost effective. This includes transitioning from 40G to 100G and eventually the emerging 400G ethernet capability. It not only means more fiber cable, but an increased number of connections. The following factors will affect data center efficiency and scalability directly.

Bandwidth

The demand for speed and higher bandwidth has instigated a migration from OM3 and OM4 multimode cabling to the faster and more efficient OM5. OM5 has some serious advantages over OM3/4, including:

  • Color – OM5 is ‘lime green’ in color, while the OM3/4 is usually aqua colored
  • Compatibility – Jacket size remains at the industry recognized standard (2mm), so it can be retrofitted with OM3/4 without a major change in infrastructure
  • Scalability – OM5 has the capacity to support current data needs and the 400G needs of the future
  • More efficient – OM5 is more efficient at longer distances

It’s worth noting that OM5 is more expensive currently, as cables have to be custom made, whereas OM3/OM4 are production cables, pre-made by the thousands and in all stock lengths.

Because of this, perhaps the best feature of OM5 is its compatibility with OM3/4. There is no need to change the entire network at once, so changes can be made incrementally as the needs of the data center change.

The main thing to remember is that scalability demands the ability to increase bandwidth at need. Hence the time to plan for what’s next is now.

Insertion Loss

The simplified version of insertion loss is this: the more connectors you have, the greater potential there is for loss of speed. A lower insertion loss means a stronger signal. Data centers should understand their insertion loss margin.

This margin is the actual insertion loss experienced vs. the standard insertion loss, and it can be affected by a number of things. So how do you reduce insertion loss?

  • Rack optimization – The right rack and cabling solutions will reduce the distance data has to travel, decreasing loss
  • Air flow – Temperature controls, or factoring in realistic temperatures, help manage insertion loss expectations
  • Connectors fit for purpose – The right connection components will also reduce loss, and the expected loss of these components should be factored in when being calculated

Efficient data center that are set up to be denser and reduce the distance data has to travel, have lower potential for insertion loss. Note the word “potential.” Since many factors, from the quality of cabling and connections, to the efficiency of rack and cabling solutions can have an impact, its necessary to look at this factor from several angles.

Skew

Skew is the difference between the time it takes light to travel on different fibers. Too much skew can result in data loss or errors.

The standards for skew are tight in parallel optical cabling solutions, as low as .075 n-s (nanoseconds). The simple reason for this, is that skew can affect the longevity of optical cables and how scalable they are when it comes to higher data rates and volumes – two of the primary factors in scalability.

This is another factor that can get complicated at times, and is influenced by the length of cables, the type of cable used and more. The key is to know what to look for in parallel optical circuits: low skew components with tight tolerances over the distance you need to run them.

Physical Layer Optimization

We’ve mentioned that for peak data center efficiency, you need to be dense, fast and cost effective, enabling you to be scalable and respond rapidly to future data volume and speed needs. While cabling and connectors are important, the fourth factor is making the best use of your physical layer.

Fundamental to this is the optimization of server racks and cable management systems. This means optimizing your server configuration. One of the smartest ways to do so, is to replace your 1RU and 2RU horizontal managers with intelligently designed Zero U cable managers, which use no additional rack space. The patented system design by AnD Cable Products can take you from using four racks to three through smart rack optimization.

Multiply that by the number of server racks in your system, and you’re looking at real space savings. Add better cable management and more efficient cables, and you can reduce your physical footprint, and equipment costs, significantly.

Cable management systems need to help regulate air flow, ensure devices are easily accessible and allow for cable identification and tracking.

The choices you make now around how you optimize your rack and cable management, bandwidth, insertion loss and skew can set you apart and ensure your readiness to meet the needs of tomorrow.

How are you preparing to meet the future, today? Have questions about your current rack systems, cables, and even system security? AnD Cable Products can help – Contact us today.
