2016 was certainly an interesting year in the data centre world, as we saw the ripple effects of the seemingly insatiable demand for cloud computing, emergence of edge computing, and growing interest in the Internet of Things (IoT), among other trends. Against this backdrop, I’ve been thinking about what we can expect for 2017 and have come up with a few predictions.
Hyperscale data centres
I don’t expect demand for cloud computing to subside, which means the Internet Giants will continue to build more compute capacity in the form of hyperscale data centres. Market forces will demand they build these data centres increasingly quickly, meaning 10MW to 20MW projects done from start to finish in less than a year.
One key to accomplishing such a feat is the use of prefabricated, modular data centre components. Everything from power and cooling modules to IT space can now be ordered ahead of time, built in a factory, loaded on a skid or installed in a container and put together on site. IT equipment can be built in parallel to the facility, installed in racks, then shipped to the site and quickly rolled into place. This equipment may even be designed to operate at temperatures that match the ambient temperature of the site location, dramatically minimising cooling requirements, reducing complexity and improving efficiency.
Building out the massive data halls with compute capacity can be challenging, labor intensive and time consuming. A new deployment model is emerging where freestanding backbones are assembled in the data halls while at the same time, IT equipment is racked and stacked in IT racks. The populated IT racks can then be quickly and easily rolled into place, greatly reducing time and complexity.
A critical edge
Edge computing will continue to grow in importance as companies increasingly host applications and IT equipment outside of their own data centres, using cloud providers of various types. The trend will put the focus on issues including latency, availability of adequate bandwidth, security and meeting regulatory requirements regarding where data needs to be hosted from a geographic perspective. Edge computing can play a role in addressing each of these concerns.
But these edge data centres will be no less important to companies that operate them than large, centralised data centres are. So they will need many of the same reliability and availability attributes as larger data centres, including:
- Redundant power supplies and cooling
- Multiple wide-area network connections
- Remote monitoring capabilities
- Physical security systems
Expect to see products emerge specifically for small data centres that have redundancy and security features built in.
Data centre standards battle continues
Increasingly, the IT equipment in our data centres will adhere to emerging standards intended to promote scalability, reliability and cost-effectiveness. The most prominent such effort, the Open Compute Project (OCP), has developed standards for servers, storage and networking equipment that have seen significant adoption.
But large companies including Google, LinkedIn and Microsoft will seek to put their own stamp on the standards, potentially putting a wrench in the works in terms of the industry coalescing around a single set of standards – a familiar story in IT history. As always, it’ll take time for the winners and losers to shake out.
Lithium ion takes hold
My final prediction is that lithium-ion (Li-ion) technology will play a significant role in data centres, almost certainly with respect to UPSs and possibly for long-term energy storage.
With respect to UPSs, Li-ion presents several benefits as compared to traditional valve-regulated lead-acid (VRLA) batteries that we’ve been using in UPS systems for decades. Li-ion batteries provide more power in far less space, and can tolerate a much larger temperature range than VRLA batteries. They’re also easier to manage because they support sophisticated monitoring systems, and they last longer. There’s a lot to like, so much so that it seems inevitable that we’ll be seeing lots more li-ion-based UPSs in data centres (and elsewhere) in the near future.
I also see li-ion technology playing a role in helping data centre operators reduce costs for electricity. I expect large-scale li-ion battery arrays will emerge that enable users to store power from renewable sources like solar and wind for use at later times. Or, users could charge the batteries late at night, when the cost of electricity is lower, and use the power during peak demand times.
Either way, the technology holds promise in helping companies reduce the demand charges they pay utilities when they consume large amounts of power, even if only for a short time. For some customers, the charges can double or triple their electricity bill. If they can instead turn to the energy stored in their li-ion arrays, they can avoid those charges altogether.
I’m not 100% sure all the infrastructure required to make that happen will be in place in 2017, but I expect to see trials, at least. Watch this space and we’ll keep you posted.
