Modular Data Centers – Are They for You?

What are the major benefits of building a data center with modularity in mind? Why is it such a popular option right now?

Modular data centers – or data centers that are that are portable, pre-configured and set up inside of either shipping containers or other prefabricated housings – have become quite popular over the past few years for several reasons.

First and foremost, they are quick and inexpensive.  By having a “cookie cutter” design, set-up and manufacturing time and costs can be kept a minimum, allowing them to be sold at a reasonable cost and to be deployed far more quickly than a traditional data center. They also have lower upfront costs than a brick-and-mortar data center.

Modular data centers are also built with efficiency in mind, some designs allowing for cooling costs that are significantly lower than those in a traditional data center. They also tend to have very low PUE ratings, sometimes as low as 1.12, which is an improvement from the 2013 national average of 1.65, as reported by the Uptime Institute.

Another major benefit of modular data centers, and pretty much everything else in today’s IT world, is their scalability.

How can a company know that data center modularity is a fit for them and that it’s an approach they should consider?

A company might consider looking into a modular solution if:

-They are unsure of their future needs: Building a conventional data center is a huge expense, especially if the company building it is uncertain of their future requirements. If the company is in need of a data center now, but unsure of what their needs will be down the line, a modular solution could be a great place to start.

-Their budget is tight: As will be explained in the next question, modular data centers have much lower capital costs than brick-and-mortar ones.

-Time-frame is a consideration: Companies that require either a new data center (or an expansion of their current one) but are short on time are the ideal customer base for modular data centers. These centers can be implemented within a matter of months.

-A temporary increase in capacity is needed: For companies that might only need increased capacity seasonally, for certain projects, or only for a particular stretch of time, a modular data center could be a potential solution to consider.

How does modularity compare in terms of cost and time to other data center building or redesign options?

There is a large delta between the cost of a modular data center and the cost of a traditional brick-and-mortar one, and a major selling point for modular data centers is the lower upfront costs versus those of a conventional build. This goes hand-in-hand with the scalability of modular data centers.

When planning the budget to build a brand new data center from the ground up, it is necessary to consider not only the capacity requirements needed now, but those that might be needed many, many years down the line – no one wants to build a data center that will only support their needs for five or so years. Modular data centers, however, allow you to purchase a unit that fits your current needs. Then, after that five years has passed and you’ve outgrown the single module, you can simply purchase another. It allows you to take the large cost involved in building a data center, and break it down into far more reasonably sized chunks.

The time involved in building a traditional data center will obviously vary, depending on the size and scope of the project, but the general time frame for a ground-up build is from a year and a half to two years. The time frame for redesigning a data center cannot easily be averaged, since there are far too many factors to be considered (what specifically is being redesigned and how, the size of the facility, etc.), however it is safe to say a redesign would take several months at least. Modular data centers, though, can be ready to use within a matter of months.  They are almost always the quickest solution to deploy.

What does a modular data center build or redesign entail? What should companies expect from the process and what should they do to make the process go as smoothly as possible?

While deploying a modular data center may seem simpler than building a brick-and-mortar one, it does still have its own considerations. First, you’ll need to determine whether or not real estate is available. This is generally not too large of a concern, though, considering that modular data centers can usually be placed anywhere, such as in the parking lot or on a building’s roof (given that you’ve verified its load bearing capabilities!). Security is an important consideration as well; modular data centers need to be monitored with the same stringency that a regular data center would, which will require the procurement of surveillance equipment that can withstand outdoor conditions.

You’ll also need to determine whether or not you want to supply your own equipment. Many modular solutions on the market allow you to purchase the servers along with it, which provides you with the servers at a lower cost versus buying them independently. However, this also adds upfront costs to the implementation.

If the modular data center is being procured to supplement an existing one, you’ll need to ensure that sufficient power is available for the new systems. Some existing centers will have additional power and cooling capacity, and if so, it will just be a matter of making sure you are aware of how much extra capacity exists. However, if the existing center is already at capacity, you will need to plan for adding additional power systems to support it. Older buildings might not be able to support the additional requirement without upgrades being made.

Companies can help make the process go more smoothly by carefully reviewing the project budget ahead of time, and by being informed of their power demands and current capacity.
