M2-W6930-64QC Data Center Switch

The M2-W6930-64QC data center switch offers a 64-port 400G interface in 4RU chassis, which delivers the highest performance combined with complete L2 and L3 forwarding features in modern large-scale data center networks. Each is supporting 1 x 400G QSFP56-DD, 2 x 200G (4 lanes 50G PAM4), 4 x 100G (2 lanes 50G PAM4). The M2-W6930-64QC can be deployed as a spine switch supporting spine-to-spine or spine-to-leaf interconnects. This open network switch is loaded with the Open Network Install Environment (ONIE) software installer and OpenBMC, which support the SONiC operating system.
