Huawei CloudEngine 12700 switch targets data center and campus networks

Huawei has launched CloudEngine 12700 series core switch targeting data center networks and high-end campus networks.

Launched at the Gartner Summit ITxpo in Goa, Huwei CloudEngine 12700 series switches use the Huawei VRP8 software platform.

Huawei says the CE12700 switches provide maximum of 48 Tbps switching capacity and high-density line-speed ports. These switches use Clos-based architecture and a front-to-rear ventilation channel design to provide industrial-grade reliability.

The switches also provide comprehensive virtualization capabilities and data center features. Moreover, the CE12700 switches use innovative energy-saving technologies to greatly reduce power consumption. The company does not share details on reduction in power consumption.

The CE12700 also uses Variable Size Cell (VSC) for dynamic routing. A unified arbitration mechanism is used to ensure fair route selection and load balancing between switching paths so that links are used at 100 percent. Virtual output Queueing mechanism adds packets with different destinations to multiple virtual output queues to prevent head of line blocking (HOL).

The CE12700 series provide industrial-grade reliability, with a mean time between failures (MTBF) of 22.5 years. To prolong durability, the power supplies support N+N backup and have an independent heat dissipation system. Each fan tray has two counter-rotating fans working in 1+1 backup mode, said Huawei.

Huawei says that the CE12700 also has a large-scale routing bridge, supporting TRILL which helps build a large Layer 2 network with more than 500 nodes, resulting in flexible service deployment.

CE12700’s digital power modules have a power efficiency of 96 percent. The CE12700 can adjust the power consumption of components to adapt to changes in service traffic volume, saving energy dynamically.
