1U Open Ethernet Switch with Onyx 32 QSFP28 Ports

The SN3700C is a 1U 32-port 100GbE Open Ethernet Network spine that can also be used as a high density 10/25GbE leaf when used with splitter cables. The SN3700C switch allows for maximum flexibility, with ports spanning from 1GbE to 100GbE and port density that enables full rack connectivity to any server at any speed, and a variety of blocking ratios. SN3700C ports are fully splittable to up to 128X 10/25GbE ports.
