Quick take This guide covers how to use a QSFP-DD to 4×QSFP56 breakout DAC to cable one 400G switch port into four 100G links for in-rack / adjacent-rack deployments. It focuses on AI/HPC pods first, then extends the same cabling discipline to campus core + storage e...

Quick take 10G is still common for legacy access and cost-sensitive edge links, but it can become a scaling bottleneck in modern racks. 25G became the “default” server-access speed in many data centers because it delivers a big jump in bandwidth per port with a clean operational mo...

Quick take Two DAC cables can both say “100G QSFP28” and still behave very differently in a real rack. Price gaps usually come from things you don’t see on the outside: jacket material and formulation, shielding construction, connector contact plating, overmold/potti...

Quick answer They’re all “100G-class” choices, but they’re built for different downstream realities. Pick 1×100G when you’re linking 100G-to-100G devices (uplinks, inter-switch links) and want the cleanest operational model. Pick 2×50G whe...

Quick Answer A Direct Attach Cable (DAC) is a factory-assembled high-speed copper cable with fixed connector “module-style” ends. It’s widely used for short-reach links in data centers because it delivers low latency, simple deployment, and cost-ef...

Quick Answer If your rack is built around 25G servers but your switch layer is standardized on 100G, one of the cleanest ways to control cost is to fan out a single 100G port into four 25G connections using a QSFP28 to 4×SFP28 breakout DAC. It incr...

Quick Answer: MLO is Not About Speed, It’s About Reliability When WiFi 7 is discussed, most attention goes to headline throughput numbers. From an enterprise engineering perspective, however, the most transformative feature of WiFi 7 is Multi-Link Operation (MLO). ...

Introduction In a leaf-spine data center, "the right" Network Packet Broker (NPB) is the one that can be proved in acceptance testing: (1) high 100G density today, (2) a clean path to 400G (including bre...

Introduction In enterprise environments, "top-rated" Network Packet Brokers (NPBs) are not defined by the biggest port count. They are the ones that can be accepted with evidence: ...

Introduction A Network Packet Broker (NPB) project fails not because "the link doesn't come up," but because tools don't receive traffic that is stable, analyzable, and verifiable under peak conditions. Your success criteria should always verify three segments end-to...
