The Huawei CloudEngine S6750-H series 25GE switches are next-generation enterprise-class core and aggregation switches, featuring 48 x 25GE optical downlink ports and 8 x 100GE optical uplink ports. These switches deliver high performance, exceptional reliability, cloud-based management, and intelligent O&M.
The Huawei S6750-H48Y8C is a high-end, high-density 10 Gigabit switch in the Huawei S6750-H series. Its core advantage is "high-density, heavy-load, and high-reliability networking for medium and large-scale scenarios"—48 25G optical ports adapt to 10,000-15,000 terminals, 8 100G optical ports support ultra-high-speed uplink, with a total switching capacity of ≥6.144Tbps and a forwarding performance of 2592Mpps. It is equipped with a high-end forwarding chip and ≥64MB of large-capacity cache, and integrates enterprise-level functions such as hardware-level dual redundancy, enhanced stacking, and intelligent traffic scheduling. It has a built-in 9KV surge protection + industrial-grade hardware architecture, with an annual failure rate of <0.01%. It is the high-end first choice for medium and large-scale campus core layers, data center aggregation layers, and enterprise backbone networks that "balance high-density access, ultra-large bandwidth, and stability".
S6750-H48Y8C FAQ
Q1: What are the core differences between this and the regular S6750-S16X10Y2CZ in the same series?
A1: The former is a high-density, heavy-load model with 48 25G ports for access and 8 100G ports for uplink, offering stronger hardware redundancy and forwarding performance, suitable for medium to large-scale high-density scenarios; the latter is a regular full-rate model with lower interface density, offering better cost-effectiveness, suitable for medium-sized basic scenarios.
Q2: Will there be lag when 48 25G ports are simultaneously connected to high-load devices (such as high-performance servers and cloud terminals)?
A2: No, the total switching capacity is ≥6.144Tbps, with a forwarding performance of 2592Mpps. Combined with a 64MB enhanced cache and heavy-load forwarding algorithm, it can easily handle 15,000 concurrent terminal transmissions without lag or packet loss.
Q3: Is it necessary for medium to large enterprises to choose a high-density 25G+100G combined switch?
A3: 25G high-density access adapts to high-density terminal/server deployment, 100G uplink solves bandwidth bottlenecks, and hardware redundancy reduces the risk of network outages. The combination of these three features adapts to the business expansion needs of medium and large enterprises, resulting in superior long-term comprehensive value.
