Cisco Introduces New Nexus 400 Gigabit Ethernet Switches

Supporting data-hungry apps like streaming video, or apps that use artificial intelligence (AI) and machine learning, Cisco’s new Nexus Gigabit Ethernet (400G) switches would allow organizations to create “more powerful networks, more cost-effectively and in a fraction of the space.”

Cisco’s new 400G switches would provide four times the bandwidth and four times the scale of existing switches without using four times the power. The new switches are built on Cisco’s Nexus product portfolio, which allows users to choose deployment of 400G in the way that best meets their requirements – whether they are a webscale company, running a high-density or intent-based network, or using specialized apps. These switches can also be used on their own or in combination with Cisco’s security, automation, visibility and analytics software.

Dell’Oro predicts the market for 400G will grow quickly, reaching $1.5B in 2019 and more than doubling by 2020.


“Our 400G switches do more than just bring a new level of speed to customers. They support the delivery of the signature capabilities that customers expect for their modern data-driven workloads and cloud environments,” said Roland Acra, SVP, General Manager Data Center Business Group, Cisco. “Superfast policy, segmentation and whitelisting. Real-time visibility into packets, flows and events. Smart buffering for big data and machine learning workloads. The ability to prioritize critical traffic on-demand. These are the things that Cisco has delivered to our customers across multiple generations of Nexus switches. And we are doing so again with our new 400G portfolio.”

Cisco is beginning early field trails with customers in December 2018, giving IT organizations planning time to set up trials as soon as possible. The new Cisco Nexus 400G switches will be generally available in the first half of calendar year 2019.
