Data Center Switches

25G, 100G and 400G switches for spine-leaf networks, private cloud and AI. Open, SONiC-ready software and hot-swap power and fans.

In plain numbers

How fast is fast?

One port, one second. This is how much data each speed moves.

25G

About 3 GB every second

A full-length HD film in about two seconds. For each server in the rack.

100G

About 12 GB every second

Four times 25G. Links the racks to the spine.

400G

About 50 GB every second

Sixteen times 25G. For GPU clusters that share data all the time.

Leaf and spine

Any rack to any rack in two hops

  • Leaf switches connect the servers in each rack.
  • Spine switches join every leaf to every other leaf.
  • All paths work at the same time. If one link fails, traffic uses the others.
  • To grow, add a leaf or a spine. No redesign.

Why D-Link data center switches

Open, fast and always on

One software platform on all three models, so you learn it once and use it from the leaf to the spine.

SONiC-ready open software

Ships with ONIE. Load an open network operating system and avoid lock-in.

Lossless Ethernet for AI

RoCEv2 with PFC and ECN keeps GPU traffic moving without packet loss.

EVPN-VXLAN

Stretch networks between racks and sites over a routed fabric.

MC-LAG

Connect each server to two switches. If one stops, the other keeps the link up.

Hot-swap power and fans

Two power supplies and spare fans. Replace one while the switch runs.

AC or DC power

Fits enterprise rooms and telecom sites with DC power.
