Big Data, mobility and the Internet of Things (IoT) are generating an enormous amount of data, and data center operators must find ways to support higher and higher speeds. Many data centers were designed to support 1-gigabit or 10-gigabit pathways between servers, routers and switches, but today’s Ethernet roadmap extends from 25- and 40-gigabit up through 100-gigabit, and 400-gigabit and even 1-terabit Ethernet loom within a few years. As a result, data center operators have an immediate need to migrate their Layer 1 infrastructure to support higher speeds, and that new infrastructure must also deliver lower latency, greater agility, and higher density. In this article, we’ll look at the challenges of moving to higher-speed cabling infrastructure, and how to plan for the future.
Recent data center trends predict bandwidth requirements will continue growing 25 percent to 35 percent per year. A key impact of this sustained growth is the shift to higher switching speeds. According to a recent study by Dell’Oro, Ethernet switch revenue will continue to grow through the end of the decade, with the biggest sales forecasted for 25G and 100G ports. The shift to 25G lanes is well underway as switches deploying 25G lanes become more commonplace. Lane capacities are expected to continue doubling, reaching 100G by 2020 and enabling the next generation of high speed links for fabric switches. A number of factors are driving the surge in data center throughput speeds.
