CE6875-48S4CQ-EI FAQ
Q1: Are the 48 25GE optical ports backward compatible with 10G/1G devices? Is no additional configuration required?
A1: Yes, they support automatic adaptation to 25G/10G/1G speeds. No manual configuration is required. They can directly connect to older 10G/1G servers or terminals, offering excellent compatibility and protecting existing equipment investments.
Q2: What are the differences between this model and the Huawei CE6881 series (25GE)? How to choose?
A2: This model focuses on high-density access in medium to large-scale scenarios, with more comprehensive dual-controller redundancy, suitable for core-level deployments; the CE6881 series focuses on mid-range data centers, offering better cost-effectiveness, suitable for basic access layer scenarios.
Q3: Is the bandwidth of the four 100GE uplink ports sufficient to meet the forwarding requirements of 48 25GE servers?
A3: Fully meets the requirements. The total bandwidth of the four 100GE ports reaches 400Gbps, and the total bandwidth of the 48 25GE servers running at full load is 1200Gbps. Designed according to the 50% convergence ratio of the data center, the uplink bandwidth is sufficient and there is no bottleneck.
