Description
Huawei CE7855-32Q-EI Switch is a new generation of high-performance, high-density, low-latency 40GE Ethernet switches for data centers and high-end campuses.
Huawei CE7855-32Q-EI Switch Product Overview
Huawei CE7855-32Q-EI Switch provides high-density 40GE QSFP+ ports, and supports rich data center features and high-performance stacking. This helps enterprises and operators build data center network platforms for the cloud computing era. Huawei CE7855-32Q-EI is located at the core or aggregation of the data center and can also be used for the core or aggregation of the campus network. CloudEngine 7800 series support multiple data center features: Priority-based Flow Control (PFC), Enhanced Transmission Selection (ETS) and Data Center Bridging eXchange (DCBX). These features ensure low latency and zero packet loss for FC storage and high-speed computing services.
Users or third-party developers can use open APIs to develop and deploy specialized network management policies to implement extension of fast service functions, automatic deployment, and intelligent management. The OPS also implements automatic operation and maintenance, and reduces management costs
Additionally, Huawei CloudEngine 7855-32Q-EI Switch can work with the CloudEngine 16800/CloudEngine 12800/CloudEngine 6800/CloudEngine 5800, which is a flexible, simple, open, and secure cloud data center network.

Huawei CE7855-32Q-EI Switch Product Features
- High-density 40GE convergence, superior capacity
2.56Tbps switching capacity (1U); 1440Mpps forwarding performance, L2/L3 full line-rate forwarding;
Provides 32 40GE QSFP+ interfaces that can serve as the core or aggregation switch for data center and campus networks;
The QSFP+ interface can be split into 10GE SFP+ interfaces to provide flexible networking capabilities and build a non-blocking network platform with the CE12800/CE6800/CE5800 series.
- Highly reliable long-distance stacking for superior performance
16 stacking technologies:
16 switch stacks provide up to 512 40GE access ports to meet high-density server access requirements in data centers;
Virtualize multiple devices into one logical device to build a scalable, manageable data center network platform;
Stacking system realizes redundant backup of control plane and data plane, avoiding the risk of a single point of failure and greatly enhancing system reliability
- Fusion enhanced Ethernet, unified bearer
- Supports FCoE (Fibre Channel over Ethernet) to implement unified hosting of storage services, data services, and computing services, reducing customer network construction costs and maintenance costs.
The centralized FCoE/FC gateway deployment solution, the Ethernet access device does not need to participate in the calculation of the FC protocol, and it is compatible with the current FC SAN, which reduces the operation and maintenance complexity;
Support data centers such as PFC, ETS, and DCBX with no packet loss, meeting the low latency and no packet loss requirements of FC storage services and high-performance computing services.
