The next-generation data centre will exist beyond walls, seamlessly integrating core facilities with a more intelligent, mission-critical edge of network. These Gen 4 data centres are emerging and will become the model for IT networks of the 2020s. The advent of this edge-dependent data centre is one of five 2018 data centre trends identified by a global panel of experts from Vertiv, formerly Emerson Network Power.
“Rising data volumes, fuelled largely by connected devices, has caused businesses to reevaluate their IT infrastructures to meet increasing consumer demands,” said Giordano Albertazzi, president of Vertiv in Europe, Middle East and Africa. “Although there are a number of directions companies can take to support this rise, many IT leaders are opting to move their facilities closer to the end-user – or to the edge. Whatever approach businesses take, speed and consistency of service delivered throughout this phase will become the most attractive offering for consumers.”
Previous Vertiv forecasts identified trends tied to the cloud, integrated systems, infrastructure security and more. Below are five trends expected to impact the data centre ecosystem in 2018:
1. Emergence of the Gen 4 Data Centre: Whether traditional IT closets or 1,500 square-foot micro-data centres, organisations increasingly are relying on the edge. The Gen 4 data centre holistically and harmoniously integrates edge and core, elevating these new architectures beyond simple distributed networks.
This is happening with innovative architectures delivering near real-time capacity in scalable, economical modules that leverage optimised thermal solutions, high-density power supplies, lithium-ion batteries, and advanced power distribution units. Advanced monitoring and management technologies pull it all together, allowing hundreds or even thousands of distributed IT nodes to operate in concert to reduce latency and up-front costs, increase utilisation rates, remove complexity, and allow organisations to add network-connected IT capacity when and where they need it.
2. Cloud Providers Go Colo: Cloud adoption is happening so fast that in many cases cloud providers can’t keep up with capacity demands. In reality, some would rather not try. They would prefer to focus on service delivery and other priorities over new data centre builds, and will turn to colocation providers to meet their capacity demands.
With their focus on efficiency and scalability, colos can meet demand quickly while driving costs downward. The proliferation of colocation facilities also allows cloud providers to choose colo partners in locations that match end-user demand, where they can operate as edge facilities. Colos are responding by provisioning portions of their data centres for cloud services or providing entire build-to-suit facilities.
3. Reconfiguring the Data Centre’s Middle Class: It’s no secret that the greatest areas of growth in the data centre market are in hyperscale facilities – typically cloud or colocation providers – and at the edge of the network. With the growth in colo and cloud resources, traditional data centre operators now have the opportunity to reimagine and reconfigure their facilities and resources that remain critical to local operations.
Organisations with multiple data centres will continue to consolidate their internal IT resources, likely transitioning what they can to the cloud or colos while downsizing and leveraging rapid deployment configurations that can scale quickly. These new facilities will be smaller, but more efficient and secure, with high availability – consistent with the mission-critical nature of the data these organisations seek to protect.
In parts of the world where cloud and colo adoption is slower, hybrid cloud architectures are the expected next step, marrying more secure owned IT resources with a private or public cloud in the interest of lowering costs and managing risk.
4. High-Density (Finally) Arrives: The data centre community has been predicting a spike in rack power densities for a decade, but those increases have been incremental at best. That’s changing. While densities under 10 kW per rack remain the norm, deployments at 15 kW are not uncommon in hyperscale facilities – and some are inching toward 25 kW.
Why now? The introduction and widespread adoption of hyper-converged computing systems is the chief driver. Colos, of course, put a premium on space in their facilities, and high rack densities can mean higher revenues. And the energy-saving advances in server and chip technologies can only delay the inevitability of high density for so long. There are reasons to believe, however, that a mainstream move toward higher densities may look more like a slow march than a sprint. Significantly higher densities can fundamentally change a data centre’s form factor – from the power infrastructure to the way organisations cool higher density environments. High-density is coming, but likely later in 2018 and beyond.
5. The World Reacts to the Edge: As more and more businesses shift computing to the edge of their networks, critical evaluation of the facilities housing these edge resources and the security and ownership of the data contained there is needed. This includes the physical and mechanical design, construction and security of edge facilities as well as complicated questions related to data ownership. Governments and regulatory bodies around the world increasingly will be challenged to consider and act on these issues.
Moving data around the world to the cloud or a core facility and back for analysis is too slow and cumbersome, so more and more data clusters and analytical capabilities sit on the edge – an edge that resides in different cities, states or countries than the home business. Who owns that data, and what are they allowed to do with it? Debate is ongoing, but 2018 will see those discussions advance toward action and answers.
