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...

Introduction H3C S9850-32H is a "clean" 32×100G QSFP28 fabric building block that shines when you want simple 100G pod math, repeatable spine/aggregation designs, and a deployment approach that scales by copying proven templates (not reinventing racks). It's also su...

Read this firstly If you're choosing between H3C S9850-32H and H3C S9855-48CD8D, don't start with "which is newer?"-start with what role the switch must play in your fabric. Pick S9850-32H when you need a clean, 32×100G-class building block for a 100G spine / agg...

The Ruijie RG‑S5360 Series represents high-performance 10GE switches tailored for campus backbones and aggregation layers. With 24/48 gigabit downlinks, 4×1G/2.5G/10G uplinks, PoE+ options, hot-swappable dual power, RGOS 12.X modular OS, and industrial-grade protections. The RG‑S5360 ...

TL;DR - 2026 Key Takeaways Spine-leaf remains the default DC fabric in 2026 because it scales predictably with ECMP and repeatable "pods." The biggest performance failures rarely start at the server port-they start in uplink sizing, oversubscription, congestion behavior, and opera...

TL;DR - Key Takeaways 2026 is the "design pivot" year: 400G remains mainstream, but new builds and major expansions increasingly plan around 800G uplinks to avoid near-term bottlenecks. AI changes everything: networking is no longer "plumbing"-it's a performance multiplier. Bandwi...

Introduction If you're planning a new network or upgrading an old one, you will inevitably hit this question: Should I use Layer 2 switches, Layer 3 switches, or both - and where? In 2026, the answer is more nuanced than "L2 is cheap, L3 is advance...

Introduction As industries accelerate toward digital transformation driven by smart manufacturing, energy automation, intelligent transportation, and nationwide smart-city deployments, industrial switches have become indispensable. These devices form the backbone of modern OT (Operatio...

Intro Ethernet switch port types define the performance, scalability, and architecture of modern networks. RJ45 ports serve access-layer copper connections; SFP/SFP+ ports enable flexible 1G/10G uplinks; SFP28 delivers 25G for modern data centers; QSFP+ and QSFP28 support high-density ...

Introduction: Why SMBs Need Reliable SwitchingIn today’s connected business environment, even small and medium-sized companies rely on secure, high-performance networks to keep operations running smoothly. From cloud collaboration to IP telephony and video surveillance, network downtime directly affects productivity...
