In Part 1 of this series, we looked at the different types of budgets that must be considered when planning your next data center upgrade. Namely, the financial budget (which is a balancing act in and of itself) and the power budget, which can be significantly improved by taking advantage of engineered links.

Let’s face it. Data center upgrades are expensive and risky. There are countless factors to consider, and more than a few mildly terrifying things that go sideways if you make the wrong move. In some ways, you have to be a fortune-teller. You need to be sure that the infrastructure you install will be able to support not only current needs, but also your next generation of equipment and ever-increasing bandwidth requirements. The last thing you want to do is install a cabling plant today that you’ll have to rip out and reinstall three years from now.
I’m not going to attempt to cover all of factors that play into a data center upgrade. There are entire books, websites and even college courses devoted to that. But if we boil it all down, we’re really talking about two main considerations – budget and performance.
In the data center world, there’s more than one type of budget to consider.
Of course, there’s always a financial budget to keep in mind. We all want to have “the best” system/product/solution, but financial realities demand that we carefully examine what we need, prioritize the requirements, and choose solutions that provide the best return on our investment.
For example, looking just at cabling, traditional cable plants have used OM3 multimode fiber. Going to OM4 – or OM4+ – is more of an investment, but worth it because the added bandwidth might be needed to overcome insertion loss. Another example is single-mode vs. multimode. Single-mode is the least expensive cable, but with higher connectivity and optics costs, single-mode as a solution can be up to three times more expensive than multi-mode.
Financials are important. But they’re not the only budget you need to think about your migration path. What good is saving money on a system that doesn’t work? It’s critical to understand whether or not your cabling will support your protocol. To do that, you need to know your link budget – or power budget – and understand what you can do to maximize it.
In theory this is simple. Your system either works or it doesn’t, right? Not exactly. With the number of PMD options constantly increasing, it’s get difficult to keep track of all of the variables. A PMD is the Physical Media Dependent form factor for the transceiver connection. Each PMD has a set of conditions – fiber type, connector type, bandwidth support and cabling insertion loss – that are needed in order for it to operate correctly.
IEEE defines worst case conditions to ensure interoperability, but these limits can be very restrictive. As an alternative, many network managers take advantage of engineered links to improve performance. An engineered link is one where one or more performance attributes are specified to be better than the standard. The better performance can come from any number of different attributes. It could be from higher bandwidth fiber, or lower loss connectivity, or better performing transmitters and receivers. With the number of potential options available, the number of possible solutions seems infinite.
So now that you’ve factored in all of your financial and link loss requirements, how do you go about determining the best migration plan – one that balances your budget with your desired network performance objectives? Part 2 of this series will discuss several approaches to this challenge.

Viewed by more than 111 million people, Super Bowl LI was a definitely a game for the history books. Thirty NFL records were broken or matched. It was the first Super Bowl game to go into overtime. The Patriots broke the record for overcoming the biggest deficit to win. Tom Brady was the first quarterback to get five Super Bowl wins and four MVP titles. And, last but not least – the biggest news in my corner of the world – it was the first time my son was allowed to stay up for an entire Super Bowl game.
He was beyond ecstatic. Finally, he would get to rehash the whole game with his buddies at school, reliving every single play in excited, excruciating detail, as only 11-year-old boys do. It was a rite of passage for him.
But it didn’t quite end the way he had hoped it would. Continue reading

Last year, after attending my first-ever BISCI conference, I wrote a post about how blown away I was by…well, by everything really: the technology, the advancements, the collaboration between some of the smartest folks I’d ever encountered.
I went into that event having no idea what to expect. I had just started in the ICT industry a few months prior, and knew relatively little about what I was there to speak about, sell, and learn. (Side note: I still can’t believe they let me work our booth and talk to potential customers. Fake it till you make it, right?)
Inside the walls of Berk-Tek, we make a lot of jokes about the age-old tug-of-war between Marketing and Engineering. The Creatives vs. The Scientists. The Dreamers vs. The Pragmatists.
My guess is that, if you work anywhere remotely near the IT world, it’s the same in your organization. I suspect that our organizations are not unique in this respect. There are countless articles, blog posts, slide decks, and even cartoons (who doesn’t love Dilbert) online that talk about the Marketing vs. Engineering, or Marketing vs. IT, dynamic.

According to an Edmunds.com Car Week survey, buying a car is more stressful to most Americans than getting married or going on a first date. One third of people surveyed said they’d rather be sandwiched in the middle airplane seat than haggle over the price of a car. And there are even people who said they’d give up their Smartphones if it meant they could avoid the process altogether. Continue reading

Earlier this year, my family and I went on a dream vacation to a small Caribbean island called Turks and Caicos. We had heard from others who had been there that the place was amazing. So after two years of saving and planning we went. Bottom line, the place was everything we had heard and more. It was absolutely beautiful, with crystal clear water, plenty of things to do, and excellent service. However, there was one part of our experience that stood out as a BIG negative. Continue reading
