2024-02-10 09:00:00

Lanbras and Marvell are in close joint R&D of 32x400G Data Center Switch. It is the 4th generation of Spectrum switches, purpose-built for leaf/spine/super-spine data center applications. It provides port speeds spanning from 1GbE to 400GbE, enables connectivity to endpoints at varying speeds and carries a throughput of 12.8Tb/s, with a landmark 8.4Bpps processing capacity. It comes pre-installed with NVIDIA Cumulus Linux, a powerful open network operating system that enables advanced automation, customization, and scalability using web scale, making it ideal for web scale IT, cloud, hyper-converged storage, and data analytic applications.

With 32 QSFP56-DD 400Gpbs ports it is ideally suited for deployment at leaf/spine in data centers, where high performance is the most important, or, with 12.8Tbps total performance - as ultra-powerful appliance.

This 32x400G Datacenter Switch is primarily packaged to meet the requirements of deployments that require smaller form factor and access to all network ports and management ports from the front side of the product. RSEM-W1-32 will be used to provide 32 x 400GbE +2 x 10GbE ports solution. In the interest of achieving the smallest possible form factor, minimum cost and the lowest system power consumption.

In order to be able to fit all access, uplink and data ports on the front side of a 1U system, all data plane connectivity to this switch is provided through QSFP56-DD sockets. Each QSFP56-DD socket can operate as a single 400GbE port.

Main Ethernet access ports are QSFP56-DD sockets which support 400GBASE-SR8, 400GBASEFR8, 400GBASE-LR8, 400GBASE-ER8 and 400GBASE-DR4 physical layers. The total system contains a CPU subsystem with 16GB of DDR4 RAM and 64GB of M.2 SSD storage by the default setting. The CPU is connected to a set of central management processors that reside elsewhere in the system through an out of band control plane Ethernet connection.

This switch also supports a family of management ports such as Console, MGMT and USB. The switches also support SNMP v1/v2c/v3, a universal network management platform. In addition, the switch console port can be managed via Telnet / SSHv2, HTTP or HTTPS. The switches enable Command Line Interface (CLI), Telnet, and cluster management, which simplify device management and provide various encryption modes such as SSH2.0 to enhance network security.

The switches support SPAN/RSPAN mirroring and multiple mirroring observation ports, offering users high visibility and transparency for easy maintenance. The switches also provide a wide range of network traffic reports to help users optimize network structure and adjust resources deployment accordingly.
