What Is Driving Adoption of High Density Fiber Enclosures?

Real estate is one of the primary reasons that high density fiber enclosures are deployed in the data center. In some parts of the world, real estate is very expensive. One way to save cap ex is to try to use the smallest data center possible. The smaller the data center, the less square area required, and therefore, lower cap ex. This would certainly be the case if one is using a co-lo facility. Of course, a smaller data center also means lower op ex, e.g., less cooling, etc.

Another reason, also driven by real estate, is that the data center’s size is fixed. The data center cannot be enlarged. This might be the situation in dense urban areas where a larger space does not exist. The only way to add more functionality to the data center is to try and find a way to cram in more equipment. Hence, using a high density fiber enclosure.

Another less obvious reason for using a high density fiber enclosure is the trend towards data centers becoming profit centers. Historically, data centers were perceived as a cost of doing business. Depending on the business you are in, that may no longer be the case.

Cabinets Are More Than Big Metal Boxes

How do cabinets impact operational costs?

This question is not asked enough by data center designers, owners or managers as they build-out new whitespace. Cabinets are the foundation of the data center’s physical infrastructure, used throughout the life cycle of the facility. IT equipment that runs the applications are contained within them, the cabling that connects the equipment to the users and the LAN/SANs are terminated and managed in them, power is distributed within them, and cooling is channeled through them. They are also the most visible infrastructure element, and how they look and fit together is often an indicator of how a data center is run and managed.

Why then are they frequently taken for granted, simply considered “big metal boxes”? Why isn’t there more emphasis on cabinets being considered an asset that helps reduce operational costs?

Choosing the Right Media Type for 10 Gig Ethernet

You are ready to deploy 10 gigabit Ethernet, but what media type should you use?  As you might suspect, that is not a straightforward question to answer.  There are several things you need to consider before making the right choice, and some of the choices may be contradictory.

Does you data center require using a structured cabling solution?  If so, then you will most like stay away from Direct Attach Cable (DAC) assemblies used for 10GBASE-CR because that is a point-to-point solution, and lean toward 10GBASE-T.

Adding New Physical Infrastructure: Part 2

Integrated Infrastructure: A New Approach

In Part 1 of “Adding New Physical Infrastructure” I reviewed three typical approaches taken by managers of small and mid-sized data centers to add new physical infrastructure: (1) build-it-yourself using in-house resources to design and integrate all elements of the infrastructure, (2) rely on a single supplier for design and integration, or (3) entrust multiple best-of-breed vendors to get it done.

We have a different take. As discussed in Part 1, you are likely to face significant risks and expense as you attempt to manage a wide range of technical details, complex project management issues, and multiple vendor relationships. Leveraging physical infrastructure expertise and partnerships with best of breed power and cooling suppliers, Panduit offers an Integrated Infrastructure approach that combines the benefits of both the single-source and best-of-breed approaches with the ease of managing a single supplier.

Adding a New Physical Infrastructure: Part 1

How do you build out a new data center physical infrastructure?

Under the best of circumstances, building out new data center capacity is complex, expensive, time consuming and fraught with risk. Experts, engineers and consultants are needed for everything from designing the building shell, planning power and cooling systems, to commissioning. These are just the major categories. Think about the expertise needed to manage all the details that cascade from them!

If you are responsible for a small to mid-sized data center you may be faced with doing more of this yourself given the available resources. Increased complexity makes it difficult to find and retain people who possess all the essential skills needed to design and integrate the power, cooling, racks, cabling and other components necessary to complete the build correctly, and on-time. Taking on the coordination of the build-out in addition to normal responsibilities can be overwhelming.

Hasn’t Everyone Deployed 10G Ethernet?

The other day I was participating in a conversation with a customer about LAN and SAN speeds greater than 10G. It was a good conversation and the customer had numerous questions about migrating to 40G Ethernet; what is happening with 100G Ethernet, using multiple fibers for Fibre Channel, etc.

Toward the end of the conversation I asked them about their plans regarding deploying 40G Ethernet. They replied that they had no immediate plans for deploying 40G and that the reason they wanted to talk about it was to make sure that their LAN infrastructure could support it in the future. They plan on deploying 10G Ethernet in the new data center.

That revelation hit me with the same impact as participating in an ice bucket challenge.

Incentives For Energy Consumption

I recently had the opportunity to discuss an application for a retrofit containment system installed into an existing data center with a sales person. Not an uncommon story, given the effectiveness of separating cold and hot air streams in the data center to reduce cooling energy consumption. The part of the story that stood out for me was that the sales person enthusiastically related how the end user realized an instant payback on the containment system and had money left over. It sounded too good to be true. My first thought was just how badly is this data center being operated that the retrofitting of a containment system would yield an instant payback and still have money left over???

Practicing Good Fiber Hygiene

There is something lurking about in today’s data centers that is not mentioned in polite company and quite frankly, is ignored. Although it will not go away, one hopes that it will not rise up and wreak havoc, bringing the enterprise to a halt.

That’s right . . . bad fiber hygiene!

EEEK!

Choosing the Right Media Type

One of the frequent questions we hear from our customers has to do with choosing the right media type for their data center. On the surface, it would seem the answer is obvious: use copper between the servers and first tier of switches and use optical fiber everywhere else. Although you might find yourself nodding in agreement, that answer does not really address the real question.

The real questions is: what is the right media type for maximizing what is important to you or minimizing what is costing you?

Let’s take a look at just one of the factors you might consider when looking at the various media types: latency.

DCIM for Small Data Centers

When it comes to running an efficient operation, small data centers have many of the same concerns and challenges as their larger counterparts. One of the greatest challenges that managers of small data centers have is that they typically have limited resources in terms of technology, staffing, and financial support.

This can leave a small data center more vulnerable to inefficiencies, inflexibility for growth, and the potential for system failures. One example we run into on a regular basis occurs when the manager of a legacy data center needs to obtain power consumption and environmental data as a result of a cost reduction initiative, or difficulty finding capacity for new applications. This typically occurs in data centers that are older, may have between 20 and 30 racks, and have grown, despite best intentions, in unintended ways.
