I was recently invited to speak at several events on the Arabian Peninsula.   copper clad aluminum wire suppliers   Obtaining visas and vaccination documents in preparation for the almost three-week, five-city tour was quite a challenge—as was airport security once I arrived. Apparently, no one liked the idea of the electronics and wires of Belden’s demonstration kit traveling in the airliner cargo hold…

While much of my adventure could be better summed up in a travel warning blog, I did have the opportunity to visit with colleagues, customers and partners to glean plenty of feedback on the data center trends of the region. In doing so, I realized that the portion of my presentation focusing on energy savings wasn’t exactly of great concern in the region—in the Kingdom of Saudi Arabia, gasoline is just 45 cents a gallon.

Following are some trends I saw that do matter in the Middle East.

• Quality of Products: Data center managers in the Middle East see the importance of installing high quality products manufactured in North America and Europe. Too many of them have been burned by off-shore inferior and counterfeit cabling and components. They consistently reiterated their desire to only buy the best, and showing them headroom, high quality cabinets, intelligent PDUs and elegant cable management solutions pretty much guaranteed a sale.


• World Class DC Consideration: Data center operators in the Middle East have a strong sense  copper clad steel wire manufacturers  of pride in designing, building and operating a world class data center. Using standard measurements of quality like Tier level certification, PUE and other measurements are very important here, and questions surrounding these methods were a re-occurring event. Learning about the ASHRAE TC9.9 standard and newer operating temperatures of equipment was a big topic of interest during our breakout sessions.

Reasons for Using Shielded Cable

Like a shield used during battle, shielding in cables acts as a barrier that protects the cable from external threats, such as electrical interference (EMI). It also prevents cable signals from interfering with surrounding cables and equipment.

While not all environments demand such a robust cable, shielding is becoming more common. When it first became available, shielded cables were used in areas such as factory floors, areas with high concentrations of electrical equipment, and secure communications applications. Today, shielded cable is prevalent in many types of applications, including government, healthcare and even education.

Setting The "STP" Record Straight

There are many acronyms used to describe shielded cables, from STP to F/FTP; while many are often used synonymously, nearly all of them have different meanings. This blog provides basic information about each style, as defined by ISO/IEC 11801:200, to clear up the confusion.

Most of us understand the need for security at the main data center entrance, as we certainly do not want those with unauthorized access touching critical networking equipment.

Unfortunately, with so much data—from    copper clad aluminum wire suppliers   personal information to intellectual property—now being transmitted and stored via the data center, protecting that information from within is becoming a greater concern than ever before.

That’s why bringing security down to cabinet level makes perfect sense. Let’s take a closer look at why.

Internal Threats on the Rise

According to a 2011 survey by Gabriel Group, more than  generalclad    60% of today’s security breaches are at the hands of company insiders or others with legitimate data center access. That is certainly a scary statistic!

As the need for speed in the data center continues to grow, you’ve probably been bombarded with high speed assembly terms like SFP+, QSFP+, interoperability, DAC, AOC, EEPROM …  copper clad steel wire manufacturers   and the list goes on! High speed assemblies are ideal for a number of different data center deployments,Copper Clad Aluminum  such as top of rack (ToR) and middle of row (MoR).

With new products and technologies being introduced at what feels like a daily rate, we thought a quick guide to various high speed assembly terms and acronyms would be useful. Here are some of the most commonly used phrases used when discussing high speed assemblies.

HSAs (High Speed Assemblies)

High speed assemblies are a low-cost option for applications with passive and active cable assemblies to support fiber channel, InfiniBand and Ethernet protocols.

Welcome to the Data Center blog. Recently I gave a webinar on Data Center Trends and one of the topics I covered was the concept of holistic design. I thought I'd make that the feature of my first blog post.

Whether upgrading a Data Center or building one from scratch, Data Center managers typically have two main considerations on their mind—cost and reliability. However, there is a lot more to the puzzle, and it starts with the acceptance of an often overlooked fact: A Data Center built only for the requirements of today can be a Data Center destined to fail in the future.

A Data Center cannot just serve existing needs—it has to meet the projected demands for the future. Unfortunately, upgrades have often been completed with a short-sighted "fix it" mentality where Data Center managers strive to just fill in gaps without a true 360-degree perspective. Cost has often been measured by how much it will take to implement a solution, rather than how much it will take to operate and its total effect on the facility. For example, Data Center managers often narrowly focus on the long-term benefit of a solution (and probably some hype), rather than asking themselves what the new solution will cost to run on a daily basis, if it truly offers a return on investment (ROI), whether ramp-up time is required for employees and how exactly a solution fits within the long-term goals of the business.

The good news is that Data Center managers can move from a "fix it" to a "build it" mentality through holistic design principles. With a holistic approach, the two philosophies that anyone upgrading or building a Data Center should live by are: Think about the outcomes and Bridge the gap among actual business requirements, IT and facilities. In other words, a holistic approach looks at the outcomes of every aspect of the design with input from all stakeholders. Some of the key holistic design considerations include:

A major factor that can influence power usage effectiveness (PUE) in a data center is the type of cooling system deployed and whether or not it includes free cooling.

Free cooling is the ability to leverage existing local ambient conditions to reduce energy usage. There are several latitudes and elevations around the world where data center managers can reduce the use of CRAC units and associated cooling costs by taking advantage of outside environmental conditions. According to reports by HIS, the market for free cooling technologies will grow faster than any other cooling methods over the next four years.Copper Clad Aluminum wire

Air-Side vs. Water-Side 

There are two forms of free cooling—air-side cooling and water-side cooling.

In previous blogs on DCIM, we looked at strategies for getting buy-in from upper management and some key tips for configuring and implementing the system once you’ve gotten approval to purchase and deploy DCIM.

In this blog, I’ll delve a little deeper into the importance of open standards and integrated cabling infrastructure.

Open for Business

Early DCIM solutions promised a view of all systems and the ability to automate data center, facility and IT systems with one software package. Today, the industry recognizes that this is not a reality. For example, many facilities monitoring systems are mature and have specialized control and monitoring features.

To integrate with other systems, DCIM must be designed using open standards. This is the only way DCIM can accommodate implementation of existing inventory data, management of any data point, integration with other systems and ongoing, real-time monitoring of a wider variety of assets.

In today’s high-density virtualized data centers, keeping equipment cool is one of the topmost concerns among data center managers. And the problem is two-fold—not only does cooling represent about 30% of operational costs, but not having uninterrupted proper intake temperatures for equipment can result in overheating and failures that lead to even higher operating costs.

Consequently, many data centers oversupply cold air, placing undue financial strain on data center operations as CRAC units require more power to provide more cool air. And despite the oversupply of cold air, many data centers still experience hot spots.

Whenever hot exhaust air and cold supply air are not adequately separated, hot air can cycle back to the IT equipment intake—regardless of how much cold air is being pushed by CRAC units. Furthermore, a lack of separation between hot and cold air causes increased cold air bypass—cool air that returns to the cooling unit unused.

The combination of high energy costs and high-density IT equipment pushing average heat loads into the 10 to 15kW per rack range is forcing many data centers to deploy containment strategies. An industry proven method of eliminating cold air bypass and the mixing of hot and cold air, containment of hot or cold aisles between rows of cabinets provides several efficiency benefits.

But what exactly is the difference between hot-aisle containment (HAC) and cold-aisle containment (CAC), and how do you know which is right for you? Let’s take a closer look.

By now, we all understand the term “virtualization” in reference to server environments in the data center, but there are some new “…izations” being thrown around that deserve a closer look. 

The terms “standardization,” “modularization” and “industrialization” are some of the recent buzz words being used to describe effective data center design, and often these terms are used interchangeably with little knowledge of what they actually mean and how they work together for effective holistic data center design. 

Let’s take a closer look at these three “…izations” of data center design. 

Standardization

Rather than reinventing the wheel every time and deploying unique components from different vendors, it is much more efficient to settle on standardized building blocks for data center cabinets, connectivity and infrastructure. 

Earlier this month, I blogged about the importance of cabinet-level security in the data centerdue to the potential for internal threats.

If you’ve realized the importance of bringing security down to the cabinet level and are planning to deploy a cabinet access control system, there are many features to consider when evaluating solutions.

Flexible and Scalable

When evaluating an access control system for data center cabinets, make sure that the system is flexible to meet your specific environment. For example, in a pod-based data centers where rows or groups of cabinets are segregated by function, you might want to require access for a group of cabinets rather than at individual cabinets. You might also want to support separate front and rear cabinet door access as different teams might be responsible for accessing the front and rear of equipment.

Look for cabinet access control systems that can grow with you so that you can easily expand to support additional cabinets. Centralized IP-based systems that reside on the network are ideal for supporting access control at any number of cabinets or groups of cabinets across multiple data centers.

Big News from Netflix

It’s official: Netflix has acknowledged plans to close its last privately owned data center in the next few months. This decision means the company will be one of the first of its size to rely solely on public cloud storage.

If you’ve been following updates about Netflix’s IT infrastructure over the past few years, you know that this shift has been happening since 2008. (One source says it began eight years ago after the company experienced a significant hardware failure at its own data center.)

Netflix’s provider of choice is Amazon Web Service, but it’s interesting to note that Amazon doesn’t run its own business entirely on the cloud. Amazon also competes with Netflix on some level with its video streaming services.

Netflix’s intriguing decision to move 100% to the public cloud brings some fascinating conversations to the table …
