M2-W6930-64QC
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, including the community SONiC and the Enterprise SONiC.
