Huawei CE7855-EI-B-B0A Data Center Switch

Description

The Huawei CE7855-EI-B-B0A is a high-performance fixed-configuration data center switch from the Huawei CloudEngine 7800 series, designed for high-density leaf/spine architectures in enterprise and cloud data center environments requiring ultra-low latency and high bandwidth aggregation.

It is a 32-port 40GE QSFP+ data center switch optimized for server aggregation and spine-layer deployment, supporting scalable and resilient cloud network fabrics.

This model is typically deployed in:

• Data center spine or leaf aggregation layers
• Cloud computing infrastructure
• Enterprise private cloud environments
• High-performance computing (HPC) networks

It supports advanced data center technologies including:

• VXLAN for network virtualization
• EVPN (software dependent)
• M-LAG (multi-chassis link aggregation)
• BFD for fast failure detection
• Advanced QoS and traffic engineering

From a hardware perspective:

• 1U high-density chassis design
• 32 × 40GE QSFP+ ports
• Dual power supply slots with 1+1 redundancy
• Hot-swappable fan modules with redundant cooling design
• Front-to-back or back-to-front airflow options depending on deployment
• Carrier-grade reliability for continuous operation in data centers

This switch is part of Huawei’s CloudEngine 7800 high-performance series, positioned for 40GE-era data center fabrics where deterministic latency and high throughput are required.
