Switches

Summary In 2026, the "best" spine-leaf switch is the one that matches role (leaf vs spine), growth path (100G → 400G), and operational reality (optics + cabling + visibility)-not the one with the loudest spec sheet. Two shapes dominate most real deployments: 32×100G QSFP28 spine b...

Introduction The H3C S9855-48CD8D is a high-density 100G leaf/ToR switch built for modern spine-leaf fabrics where you want to reduce leaf count (fewer boxes, fewer configs, fewer failure points) while keeping a clear evolution path using 400G uplinks. Concretely, it...
