The Cisco Nexus3550T Dubai introduces a Programmable Network Platform, featuring a top-of-rack software application platform with a distinctively flexible low-latency design. With up to 48 ports of Ethernet connectivity packed into a single-rack unit form factor, this platform is a versatile solution. Centered around a robust programmable FPGA, it provides a comprehensive firmware development environment tailored for custom applications and use cases.

Functioning as a potent top-of-rack Ethernet switch and application platform, the Cisco Nexus3550T Dubai Programmable Switch Platform showcases its unique low-latency design and offers extensive layer 2 and layer 3 switching capabilities. Its flexibility is underscored by the presence of a programmable FPGA device, enabling long-term feature enhancements, upgrades, and fixes. Additionally, it provides a complete firmware development environment to cater to the diverse needs of custom applications.

Features

Hardware architecture

The Cisco Nexus3550T Dubai Programmable Network Platform has a fixed form factor that is built around a dynamically reconfigurable FPGA (Field Programmable Gate Array) and provides 48 ports that are 25G capable along with an x86 (Intel® Atom® processor with 8 cores up to 1.7 GHz)–management CPU. All 48 ports are directly connected to Xilinx Virtex UltraScale Plus VU35P FPGA with a “-3” speed grade. The FPGA has 8GB of High Bandwidth Memory (HBM) on board.

Ease of management

The Cisco Nexus3550T Dubai Programmable Network Platform features a console port, a Micro USB port, a 1G RJ45 port, and a 10G SFP+ port, which can be used as management interfaces. The Cisco Nexus 3550-T Platform uses a Command Line Interface (CLI) designed to address the needs of low-latency FPGA configurations. Every command available on the CLI is also available via a remote JSON RPC API to make the Nexus 3550-T easy to operate and manage at scale. The Cisco Nexus3550T Dubai includes standard enterprise manageability and deployment capability features such as automatic configuration (via DHCP), SNMP, TACACS+ authentication, on-board Python programmability, BASH shell access, and time-series logging.

Programmability

The Cisco Nexus3550T Dubai provides a powerful development framework to add application-specific intelligence to the Cisco Nexus 3550 FPGA Module using Cisco’s Nexus Firmware Development Kit (FDK). Our Cisco Nexus FDK provides all the required components to build, run, and maintain FPGA-based intelligent applications and accelerate network applications.

Statistics

The Cisco Nexus3550T Dubai supports packet-aware statistics. The Cisco Nexus 3550-T firmware has the capability to monitor for vital packet statistics, including the number of packets/bytes transmitted/received and transmit/receive errors, and deep diagnostics, including light levels, operating temperatures, transceiver capabilities, and more. All these statistics are available at no latency cost on the critical path.
