Over the past couple of years, data center infrastructure management (DCIM) vendors have done a better job of delivering features that help reduce the complexity of the integration process.

When it comes to evaluating DCIM solutions, there are several capabilities to consider, but one of the most important to look for is mobility.

Why is mobility so critical to infrastructure management? Mobility is a key feature that goes a long way in easing deployment, enabling auditing and maintaining accuracy as the data center and the DCIM system evolves.

Let’s take a closer look.

Two important channel transmission parameters that most are familiar with for Category 6A cabling to support 10GBase-T applications include alien crosstalk and insertion loss (IL).

Alien crosstalk is a measure of the noise coupling between adjacent channels that are in close proximity (i.e., sharing the same pathway). Insertion loss is a measure of the received signal and is dependent on the length of channel (i.e., the longer the channel, the weaker the signal).

But did you know that other unmentioned parameters related to the pair balance of cables and connectors are also good indicators of noise immunity and hence support for 10GBase-T?

While it might be tempting to paint unshielded twisted-pair (UTP) cables or patch cords to match wall color or other surrounding environments, you could be painting yourself into a corner.

UTP cables are NOT designed to withstand exposure to the chemical compounds found in common paint products. In fact, Belden's longstanding policy is that cables should not come in contact with any type of paint contamination, regardless of application.

While interest has been growing in powering data centers with renewable energy sources, a recent controversial paper by economist Charles Frank argues that using solar and wind energy is the most expensive alternative to carbon-based electricity generation. The paper essentially cites that nuclear power’s efficiency and ability to operate non-stop offers nearly four times the savings on carbon emissions per megawatt capacity compared to intermittent sources like wind and solar.

Ever wonder what the difference is between ultra physical contact (UPC) and angled physical contact (APC) singlemode fiber connectors and which one to use? As usual, the answer is, “It depends.”

Let’s take a closer look.

As a follow up to last week’s blog on Bonded-Pair patch cords from guest blogger Greg Deitz, there is another issue of concern surrounding patch cords.

With some vendors touting smaller diameter patch cords with 28 AWG conductors as enabling easier cable management, optimum airflow, reduced pathway fill and potentially lower operating costs, some are questioning whether these smaller diameter cords are acceptable.

It’s time to set the record straight.

Frequently squeezed and bent during installation and routinely manipulated by IT personnel, patch cords are often viewed as one of the most replaceable, commoditized components in the data center.

But as the primary connection for servers in the data center and switches in the LAN, patch cords are the front line of defense against downtime.

Since a cable channel is only as good as the weakest link, you might want to give your patch cords a little more attention.

Everybody these days seems to be talking about software defined networking (SDN) and what it means for the future of data centers.

While giants like Google and Amazon are already using some form of SDN, others are just starting to experiment with the technology. While there’s no doubt that SDN will eventually make its way from larger hyperscale data centers and cloud service providers to the enterprise, I believe we are still at least a year away from any significant adoption.

While you might not be ready for SDN today, getting a handle on the benefits and considerations can help prepare you for the inevitable.
What Is It?
