What performance metrics define the SN3700cM switch?

It delivers 6.4 Tbps aggregate throughput, 4.76 billion packets per second switching capacity, and 425 nanoseconds port-to-port latency. These specs ensure wire-speed, non-blocking forwarding across all ports, ideal for HPC and cloud east-west traffic patterns.

Does it support advanced routing and virtualization?

Yes, supports BGP-4/MP, OSPFv2, PIM-SM/SSM, ECMP, VXLAN gateways, EVPN, and MLAG. Combined with 64 VLAN groups and OpenFlow/SDN, it enables efficient multi-tenancy, overlay networks, and collapsed Layer 3 routing in virtualized environments.

What lossless fabric features are included?

Features RoCE v2, PFC, ECN, DCBX for lossless Ethernet in storage and HPC. 42MB shared packet buffer absorbs microbursts, preventing drops in NVMe-oF or RDMA workloads common in AI training clusters.
