Huawei CE7855-32Q-EI Switch Product Features
- High-density 40GE convergence, superior capacity
2.56Tbps スイッチング容量 (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 (ファイバーチャネルオーバーイーサネット) 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.
