Executive takeaways If you need dense 10G fiber access with 100G uplinks (and room to grow with interface modules), start with S6520X-30HC-EI / S6520X-54HC-EI: they ship with QSFP28 100G uplinks that can break out to 4×25G. If 40G uplinks are enough today (or you plan to break out ...

Quick Summary If you're building a 2026-ready aggregation layer-either for a campus fabric (distribution/core) or a data-center edge pod-the H3C S6530X-48Y8C is designed for the mainstream upgrade path: 25G downlinks + 100G uplinks, with resiliency options (IRF2 / M-LAG) and modern ops...

Key takeaways What it is: A high-density switch built for 25GE access + 100GE/40GE aggregation, commonly used as campus core / building distribution or a data center leaf (ToR). Why it matters in 2026 designs: The port template (48×1/10/25G SFP28 + 8×40/100G QSFP28) supports phased...

Summary If your 2026 campus build needs a high-density 10G access template with multiple 100G-class uplinks. H3C S6812/S6813 and Huawei CloudEngine S6730-H / S6730-H-V2 are the closest "same-role" options: they target 48×10G downlinks plus 6×QSFP28 uplinks (40/100G) on Huawei, and 48×1...

Summary Both switches target the same high-density 10G access / ToR role: 48 × 10G SFP+ access ports plus 6 × 100G QSFP28 uplinks. The real "upgrade value" of S6813-48X6C is not more ports-it's more headroom: higher forwarding performance and larger scale limits (MA...

Summary These two switches are built for the same "closet/ToR access" job. The core difference is access density: S6812-24X6C: 24 × 10G SFP+ + 6 × 100GE QSFP28S6812-48X6C: 48 × 10G SFP+ + 6 × 100GE QSFP28 Because both models keep the same uplink count (6 × 100G), "48-port is better...

Summary The 2026 enterprise "default upgrade" is no longer just faster access ports-it's a balanced plan: 10G as a common access baseline, selective 25G where density/performance demands justify it, and 100G uplinks as the practical way to prevent aggregation/core from becoming the...

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...

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...
