Why Nearly Everything You Thought You Knew About Prefab Data Centers is a Fabrication
Misconceptions have a habit of persisting – especially in an era of ‘fake news’.
Take for example the idea that the order in which you might drink wine or beer has some effect on how hungover you feel the next day. Beer before wine is fine but wine before beer? Oh, dear.
The reality is that it’s a lot more about how much alcohol you consume and not the order you consume it in. Most people probably know deep down that it’s a nonsense but are still happy to trot out the advice, or attribute their own sore head to an unscheduled glass of Chablis.
The truth is that a lot of decision making is instinctive and based on long-held beliefs rather than being as coldly logical as we might like to believe. And despite the wealth of intelligence and research available that also goes for decisions made at work (as well as at the bar).
The data center industry, like other sectors, has its fair share of misconceptions, myths and commonly-held beliefs. The fact that it is an industry that is largely predicated on maintaining resiliency and uptime often means that conservative, established-thinking, often take precedence. It’s better to be safe (and stay with what you know) than be sorry (invest in something new or untried).
As a result, there are whole range of emerging, and potentially disruptive technologies, that have the promise to improve efficiency and effectiveness but risk being stymied by outdated, or just plain-wrong, groupthink.
Take prefabricated modular (PFM) data centers for example. Rather than conventional – or stick builds – which rely on a lot of on-site construction, PFM involves assembling units or modules of data center infrastructure in factories and then shipping them to the site.
The technology has been around for more than a decade – and a lot longer outside of the data center. It also continues to evolve, with more and more suppliers developing new technology and services.
Despite that legacy, and continued innovation, misconceptions about PFM data centers persist including that the technology is still unproven and that it hasn’t evolved from early designs.
Logic, facts and proof don’t always trump established thinking but let’s take shot; it’s time to puncture some of those misconceptions:
PFM data centers are a niche product
Yes, PFM facilities still occupy a relatively small part of the market. But that slice is only set to grow. Demand from colocation providers that like the agility – ability to add capacity as required – as well as future demand for new edge micro-data centers related to 5G are just some of the drivers. According to industry analysts 451 Research, the market for PFM data centers is set to expand at a five-year compound annual growth rate (CAGR) of 14.4 percent through 2021 when it will have reached $4.4bn. “PFM methodology is becoming the preferred way to expand and build new data center capacity, turnkey or critical subsystems. Underpinned by industrial processes, it has distinct advantages in terms of quality control, installation speed and build consistency” said Daniel Bizo, principal analyst 451 Research recently.
PFM data centers are just containers
The fact that the first wave of PFM products from IT companies such as Sun Microsystems were based around ISO containers has meant that this form-factor has continued to be closely associated with the term PFM – perhaps to the detriment of wider uptake of the technology. Even though PFM now encompasses the full spectrum of data center infrastructure – from rows, to rooms to full facilities as well as power and thermal infrastructure – the perception that PFM = containers persists. The continuing challenge for data center industry is to communicate the breadth and flexibility of design that PFM can enable.
PFM is more expensive than conventional builds
One of the most powerful benefits of a PFM data center is that it does not require the value of faster deployment to be weighed against the additional costs commonly associated with faster delivery. PFM data centers leverage economies of scale and streamlined processes made possible by offsite assembly to enable faster deployment at a lower TCO. The economics of PFM are so attractive that they can change the cost-benefit analysis regarding expanding an existing facility versus a new build. A PFM data center may enable an organization to move a data center to a more desirable location at about the same cost as expanding and updating an existing facility.
