Frequently Asked Questions
Is 100GbE still appropriate for new builds?
Yes. For server and storage aggregation, 100GbE remains the volume sweet spot; the SN4600C concentrates 64 such ports while leaving 400GbE spines like the SN4700 above it. We design the layer split to your traffic.
Can it mix 25GbE and 100GbE in one switch?
It does. Ports flex across 10/25/40/50/100GbE, so a single SN4600C serves mixed-speed racks, with port profiles configured before delivery.
Does it handle lossless storage traffic?
RoCEv2 and the 64 MB shared buffer provide the lossless, low-latency behavior NVMe-oF and converged storage fabrics depend on.
