Huawei'sS6730-H24X6CandS6730-H48X6Cswitches are part of the CloudEngine S series and are designed for high-performance campus networks. These models supportsix fixed 100GE uplink ports,eliminating the need for additional subcards to expand uplink capacity. This design offers several advantages:

Higher reliability:Fixed ports reduce points of failure compared to modular subcards.

Simplified deployment:No need for additional hardware or configuration.

Better performance:Optimized for high-speed connectivity and scalability.

Non-Huawei switches that rely on subcards may face limitations in terms of reliability and flexibility, making Huawei's fixed-port design a competitive advantage.
