Cisco added new members to the Cisco Nexus 9000 family: The Cisco Nexus 9200 series and next-gen Nexus 9300EX switches.
Those two data center switches are the industry’s first native 25Gbps-capable switches, delivering 25/50/100Gbps speeds at the cost of 10/40Gbps.
“The Cisco Nexus 9200 is a next-generation Top of Rack switch that pushes the boundaries and exceeds performance of existing solutions,” said Trey Layton, Senior Vice President and Chief Technology Officer, VCE, the Converged Platforms Division of EMC. “These switches meet the needs for the dense, hyperconverged compute and IO intensive applications that VCE VxRack Systems address. For example, it’s not uncommon for customers with hundreds or thousands of VxRack nodes to drive millions of IOPS, as well as hundreds of gigabits per second of system bandwidth. The Cisco Nexus 9200 solves this problem.”
The Cisco Nexus 9200 platform consists of industry leading ultra-density fixed-configuration data center switches with line-rate Layer 2 and 3 features that support enterprise applications, service provider hosting, and cloud computing environments. These switches support a wide range of port speeds with flexible combinations of 1/10/25/40/50/100-Gbps connectivity in compact form factors.
Using the widely deployed industry-leading Cisco NX-OS Software operating system, the Nexus 9200 switch is designed for the programmable fabric, which offers flexibility, mobility and scale for service providers and IaaS/cloud providers; and for the programmable network which automates configuration and management for customers who want to take advantage of the DevOps type of operation model and toolsets.
