Five New Approaches for Data Center Cabling – Part 2

15 Nov 2018

Network Cabling Computer Company Pittsburgh PAAs discussed in Part 1, a properly designed network infrastructure is a prerequisite for being able to adapt emerging technology and support crucial systems cost effectively. Part 2 will discuss Modular Design, Optimized Network Infrastructure, and Virtualization.



Modular Design


An approach that has recently gained traction is building new data centers capable of supporting the demand for excellent networking capability. Companies are increasingly participating during the construction phase by becoming more involved in decisions that help decrease costs. Specially designed and portable, modular data centers utilize engineered modules and components that offer the ability to scale and allow the creation of a converged infrastructure where necessary. Such modular designs are described as portable modular data centers or containerized data centers. Structured cabling is the foundation for every modular data center.



Optimized Network Infrastructure


According to data center providers, copper and fiber technology are sufficient for current networking infrastructure. However, there is a greater demand for more speed and streamlined connectivity for PCs, servers, and data storage. Optimizing data cabling is the method for achieving both. Optimized network infrastructure typically uses component standardization, including copper and fiber cabling, racks, and cabinets. Teamed with a physical-layer cable-management system, this approach results in a network that is both accessible and organized.



Virtualization


Research has found that more than half of small and medium-sized enterprises have their workloads running on virtual machines. In addition, more than 9 in 10 data center providers are now offering virtualization services to businesses. Proven to be scalable and cost-effective, virtualization technology is being commonly used for these four functions: desktop, server, network, and storage. As the popularity of IT infrastructure virtualization increases, ensuring that your organization has well-designed structured cabling will grow in importance.

Five New Approaches for Data Center Cabling – Part 1

4 Nov 2018

Fiber Optic Cabling Company Atlanta GA Pittsburgh PAOrganizations and data centers have concluded that structured cabling provides a durable foundation for a sound and efficient network infrastructure. As a result, management teams are reconsidering their existing data cabling configurations. For example, organizations are thinking of transferring some or all of their IT systems to cloud-based data centers that utilize virtualization.


A properly designed network infrastructure is a prerequisite for being able to adapt emerging technology and support crucial systems cost effectively. Conventional cabling met network requirements in the past, but the growth of data and demand for speed are rapidly transforming what a business will need in the future.


New companies are planning their data center cabling structure well ahead of their first day of business to attain high efficiency, maximum utilization, and optimal provisioning. During the conception stage, data center architecture needs to address issues revolving around space, power, cooling, security, and costs.


Data transmission and storage, communications, power, and video should also be prioritized. However, monitoring, network security, system updates, backups, software support, and maintenance are also of great importance.


As you may be considering improving your company’s network, it may be helpful to keep in mind four new approaches for data center cabling discussed below.



Convergence


The concept of convergence has been applied to networking and data cabling. Functions for data, phone, and video are being offered on a single network by service providers. Introduced several years ago, the convergence approach is gaining in strength via structured cabling for data centers.


Applying this approach allows for greater cable density or minimizing cable usage, resulting in providing the proper network capacity for a particular architecture and delivering the advantages below:




  • High density server racks and storage arrays reduce cable pathways for improved air flow.

  • Input and output convergence offers simplified data cabling and greater design flexibility.

  • Higher-density connectivity and higher-capacity cables provide improved performance.

Why Your Company Should Avoid CCA Cabling – Part 2

30 Oct 2018

Cat6 Office Cabling Dallas TX Pittsburgh PAAs discussed in Part 1, companies that have a limited budget for network infrastructure may end up buying copper clad aluminum (CCA) cabling to save money. Although marketed as a sufficient substitute for solid copper cabling, CCA cables are far from being the right answer for trimming budgets. Part 2 will continue discussing CCA cabling related issues and counterfeit copper cabling.



Shortened Cable Runs


As lengthier CCA cable runs approach the 100-meter maximum, there will be a decrease of signal strength in comparison to solid copper CAT5e cabling. Reduced signal strength can result in data loss because increased packets of data must be retransmitted.


Unsuitable for Power Over Ethernet (PoE)


Since CCA wires have a higher DC resistance (about 55% greater) than solid copper, its conductors may need to be 60% larger than solid copper to compensate. Without resistance compensation, the drop in voltage will be greater for any channel length.


Longer cable runs of 65 meters or more will surpass TIA’s channel DCR requirements, limiting the available voltage for the device. In addition, higher resistance will result in a faster buildup of radiant heat, which may damage the device.



How to Identify CCA Cabling


CCA wire is also much more brittle than solid copper wire. Identifying CCA is easy because all you need to find is the silver color of the tip of the conductor. Another way is scraping away the thin copper surface of the conductor to reveal the aluminum.


CCA cables also weigh much less than solid copper cables. Go to the CCCA website for the CableCheck™ mobile app (http://cccassoc.org/news/free-apps/), which provides the approximate correct box weights to help detect CCA conductors being used to fraudulently substitute for solid copper conductors.


When a CCA cable is labeled as a Category 5e, 6 or 6A cable or CMP or CMR rated, it is counterfeit cable. It will also be non-compliant with industry performance standards and will pose a hazard by being unable to pass UL fire safety testing.

Cabling Network Cable Twisted Pairs

Why Your Company Should Avoid CCA Cabling – Part 1

22 Oct 2018

Cabling Network Cable Twisted PairsIf your company has a limited budget for network infrastructure, your team may be tempted to find numerous way to economize. Unfortunately, this may lead to buying CCA cabling in order to save money. Although marketed as a sufficient substitute for solid copper cabling, CCA cables are far from being the right answer for trimming budgets.



Definition of CCA


CCA stands for copper coated aluminum. A CCA cable’s core is an inner aluminum conductor that is coated with copper. As a result, it weighs considerably less than solid copper cables.


A CCA cable can be made at a significantly reduced cost than the solid copper version. This gives a manufacturer an increased profit margin and a significant competitive edge over those companies who continue making solid copper cable.


CCA cables may look similar and are advertised to function just like standard CAT5e or CAT6 cabling, but they have serious flaws that could result in network issues, business continuity problems, and safety hazards as discussed below.



Non-Compliant


CCA twisted pair cables are non-compliant with UL and TIA standards, which require solid or stranded copper conductors. The National Electrical Code (NEC) also does not provide CCA cabling a valid safety listing. Thus, CCA cables cannot be installed legally if the facility requires CM, CMG, CMP, CMR, or CMX rated cables.



Inflexible


As CCA conductors are brittle and easily break, just transferring a faceplate or patch panel can result in failures. CCA wires have low tensile strength, and they are known to break from shearing or pulling, which can happen during packaging or delivery. Moreover, CCA cables have a very limited bend radius.



Oxidation


Aluminum begins oxidizing very rapidly when it is exposed to air. This oxidation and the resulting corrosion may lead to failed terminations inside the network infrastructure, resulting in connectivity issues.


Part 2 will continue discussing CCA cabling related issues and counterfeit copper cabling.

Office Cat6 Computer Network Cabling Pittsburgh PA

The Importance of Structured Cabling to Your Company

13 Oct 2018

Office Cat6 Computer Network Cabling Pittsburgh PAStructured cabling provides consistently high performance because of its proper design and installation, which also allows for expansion and flexibility. When designed and installed by expert technicians, a structured cabling system is composed of several components that communicate with each other. As a result, it performs with efficiency and reliability. In addition, cabling can be transferred, adjusted, and expanded with ease. The system is also future proofed, so the system can evolve with technology as the company grows.



Conventional vs. Structured Cabling


Running point to point, conventional cabling directly connects hardware by utilizing jumpers or patch cables. Differing in approach, structured cabling deploys a series of trunks or patch panels that connect to hardware. These patch panels then link to another patch panel within the Main Distribution Area (MDA), the nerve center of a structured cabling system. MACs (moves, additions, and changes) at the MDA can be accomplished with ease by using short patch cords.



Why Use Structured Cabling?


Providing a more secure, rapid, and efficient method for connecting an office, structured cabling utilizes compact and standardized patch panels connecting to the MDA. This permits easier revisions and additions. The superior organization of structured cabling lets teams address issues faster, resulting in less labor cost and downtime.


Structured cabling’s goal is a well-organized cabling system that results in rapid connections and a leaner server room. As a result, cabling requires less room and is tidier, permitting improved airflow. The regulation of temperature is optimized, which helps preserve sensitive server room equipment.



Advantages of Structured Cabling



  • Cable and port tracing performed faster

  • Decreased downtime due to improved cable organization

  • MACs eased because of improved MDA configuration

  • Reduction of cabling mass, increasing airflow and cooling

  • Speedier connections and easier troubleshooting

  • Tidier and better organized cabling


A transition to structured cabling will improve the aesthetics and organization of your company’s cable system. It will also help your team function with more speed, efficiency, and effectiveness.

Network Design Principles – Part 2

30 Sep 2018

Reliable & Manageable Scaling


Structured-Cabling,Data CablingScalability is a crucial characteristic that must be considered by network designers.


In addition, a network should also be reliable and manageable, which promote stability.  A network may be capable of expanding to several thousand routers. However, if there is a failure of some sort that causes instability due to greater processing and CPU usage required to compensate, the design won’t be successful.


A scalable network that is a challenge to manage or troubleshoot is also unacceptable.


Network problems that arise would take an excessive amount of time to address and repair, negatively impacting an organization’s business goals of the organization.


Thus, a scalable design must provide a manageable and reliable network.


Combining scalability, reliability, and manageability as the qualities of a network is a challenge. As a network expands, it becomes more complex, making management, maintenance, and repair more difficult.



Fault Isolation & Simplicity


Providing fault isolation boundaries creates fail-stop behavior for the wanted fault model. Fail-stop prevents faulty behavior from propagating past a fault isolation boundary. Effective network design must prevent a failure in one domain from spreading to other domains within a network. This is essential for the avoidance of unneeded processing and delays throughout the whole network because of a device or link failure. In addition, this will result in a converging network that has more stability, reliability, and speed.


The above concept also promotes simplicity as a network architecture characteristic, which decreases complexity in operations. Typically, fault isolation stops the propagation of network fault information across several domains or network areas. This will lead to greater network stability and the minimization of recovery time after failures.


The negative consequences due to a failure of a link or network node may spread to all devices across a network, resulting in a large volume of unneeded processing. A properly designed network using the Fault Domains Principle with its logical separation will limit the negative impact to within one fault domain.

How Improper Cabling Causes Network Issues – Part 2

12 Sep 2018

Structured Cabling Office Cabling Atlanta GAAs discussed in Part 1, the performance issues of your company’s network may be directly related to improper cabling. Part 2 will discuss Compatibility, Patch Cords, and Poor Installation.



Compatibility


Issues occasionally arise when coupling cabling and connectivity from various manufacturers. The use of jacks from one manufacturer with cabling from another, and then patch panels from a third firm is an example. This combination may result in compatibility problems. When components that are not intended by design to function together are used, network performance issues will likely result.


Purchasing top of the line high-performance cables, while utilizing lower-quality connectivity components, will produce a weak link in the chain. Cable of the highest quality will be unable to attain its full performance potential when it is married to jacks, patch panels, and plugs that are not rated to support its capabilities.



Patch Cords


Patch cords may be the top reason why there are issues in network performance.


Your company may have installed a high performance cabling infrastructure of the highest quality, but if low-quality patch cords were purchased to economize, network speed, signal quality, and overall performance will be compromised.



Poor Installation


Vetting the cabling services team you hire is perhaps the most important factor in the prevention of network performance issues. Check that the company you are considering has technicians that are properly trained and certified to install the cabling system you have chosen.


When cable installers are not properly trained, it will greatly increase the probability that your company’s structured cabling system will not be properly installed. Incompetent installation can result in problems such as improper pulling, excessive bending, and cable being installed too near sources of signal interference like large motors and machinery.


Poorly trained technicians will leave cabling that is not properly terminated or correctly polished. Sloppy work and insufficient attention to detail during installation will usually result in poor network performance, along with costly and time-consuming efforts to address the problems the substandard work caused.

How Improper Cabling Causes Network Issues – Part 1

5 Sep 2018

Data Cabling Structured Cabling Washington DCYour employees are dissatisfied by their company’s network performance, and it is affecting their productivity. A number of factors must be taken into consideration. How many users are attempting to use resources simultaneously? Have you taken into account how much the use of devices has grown? Is your network equipment sufficient to meet demand? Answering the above questions will help, but network issues may be directly related to your company’s structured cabling.



Outdated Cabling


In many instances, the age of your structured cabling system may be responsible for poor network performance. 15-year-old cabling may have met standards when it was installed, but now it may be unable to handle the ever increasing network traffic needs of your company.


An internet service provider (ISP) provides the cable that provides the connection from your company’s network to the internet. When this backbone component fails to meet today’s bandwidth standards, bottlenecks may occur.


In situations where you are attempting to operate at speeds that are too high or carry excessive bandwidth via a cable that not rated for the capacity, it will be noticeable to users and their productivity will decline, hampering business operations.



Quality of Cabling


Cabling manufacturers rate their cables in terms of capability and performance. For example, CAT6 and CAT6a cabling have different capabilities, CAT being an abbreviation for category. A manufacturer must meet the performance standards set by the Telecommunications Industry Association (TIA) for each category of cabling.


Cabling that exceeds minimum standards will attain higher network speeds without having to upgrade your cabling. In contrast, for cabling that only meets the minimum standards, the company network speed will be unable to expand much beyond the rating of the cable.


It is helpful to understand cable standards and ratings. Even though a cable is labeled Category 6A, it is not automatic that it meets the minimum performance standards of this category. The brand name and manufacturing quality will play a big role in the cable’s output.


Part 2 will discuss Compatibility, Patch Cords, and Poor Installation.
