The CloudEngine 6820 series have advanced hardware architecture with 40GE/100GE uplink ports and high-density 10GE access ports.

Product Overview

Huawei CloudEngine 6820 series switches are next-generation 10GE access switches that provide high performance and high port density on data center networks and high-end campus networks. The CloudEngine 6820 series have advanced hardware architecture with 40GE/100GE uplink ports and high-density 10GE access ports. Using Huawei's VRP8 software platform, CloudEngine 6820 series switches support extensive data center features and high stacking capabilities. In addition, the CloudEngine 6820 series use a flexible airflow design (front-to-back or back-to-front). CloudEngine 6820 series can work with CloudEngine 16800 or CloudEngine 12800 series data center core switches to build elastic, virtual, and high-quality 40GE/100GE full-mesh networks, meeting requirements of cloud computing data centers

CloudEngine 6820 series provide high-density 10GE access to help enterprises and carriers build a scalable data center network platform in the cloud computing era. They can also work as core or aggregation switches on campus networks.

CloudEngine 6820 series switches provide 48 x 10GE SFP+ ports and 6 x 100GE QSFP28 ports.

Product Characteristics

High-Density 10GE Access

• CloudEngine 6820 series provide up to 48 x 10GE ports, allowing for high-density 10GE server access and smooth evolution.
• CloudEngine 6820 series provide up to 6 x 100GE QSFP28 ports. Each QSFP28 port can also be used as one 40GE QSFP+ port, providing flexibility in networking. The uplink 40GE/100GE ports can be connected to CloudEngine 16800 or CloudEngine 12800 series switches to build a non-blocking network platform.

Inter-device Link Aggregation, High Efficiency and Reliability

• CloudEngine 6820 series support multi-chassis link aggregation group (M-LAG), which enables links of multiple switches to aggregate into one to implement device-level link backup.
• Switches in an M-LAG all work in active state to share traffic and back up each other, enhancing system reliability.
• Switches in an M-LAG can be upgraded independently. During the upgrade, other switches in the system take over traffic forwarding to ensure uninterrupted services.
• M-LAG supports dual-homing to Ethernet, and IP networks, allowing for flexible networking

Standard Interfaces, Enabling Openness and Interoperability

• CloudEngine 6820 series support NETCONF.
• CloudEngine 6820 series support Ansible-based automatic configuration and open-source module release, expanding network functions and simplifying device management and maintenance.

ZTP, Implementing Automatic O&M

• CloudEngine 6820 series support Zero Touch Provisioning (ZTP). ZTP enables the CloudEngine 6820 series to automatically obtain and load version files from a USB flash drive or file server, freeing network engineers from onsite configuration and deployment. ZTP reduces labor costs and improves device deployment efficiency.
• ZTP provides built-in scripts through open APIs. Data center personnel can use a programming language they are familiar with, such as Python, to centrally configure network devices.
• ZTP decouples the configuration time of new devices from the device quantity and area distribution, which improves service provisioning efficiency

FabricInsight-based Intelligent O&M

• The CloudEngine 6820 provides telemetry technology to collect device data in real time and send the data to Huawei data center network analyzer iMaster NCE-FabricInsight. The iMaster NCE-FabricInsight analyzes network data based on the intelligent fault identification algorithm, accurately displays the real-time network status, effectively demarcates and locates faults in a timely manner, and identifies network problems that affect user experience, accurately guaranteeing user experience.

Flexible Airflow Design, Improving Energy Efficiency
Flexible front-to-back or back-to-front airflow design

• CloudEngine 6820 series use a strict front-to-back or back-to-front airflow design that isolates cold air channels from hot air channels. This design improves heat dissipation efficiency and meets design requirements of data center equipment rooms.
• Air can flow from front to back or back to front depending on the fans and power modules that are used.
• Redundant power modules and fans can be configured to ensure service continuity.

Innovative energy-saving technologies

• CloudEngine 6820 series have innovative energy-saving chips and can measure system power consumption in real time.The fan speed can be adjusted dynamically based on system consumption. These energy-saving technologies reduce O&M costs and contribute to a greener data center.

Clear Indicators, Simplifying Maintenance
Clear indicators

• Port indicators clearly show the port status and port rate. The 100GE port indicators can show the states of all ports derived from the 100GE ports.
• State and stack indicators on both the front and rear panels enable users to maintain the switch from either side.
• CloudEngine 6820 series support remote positioning. Remote positioning indicators enable users to easily identify the switches they want to maintain in an equipment room full of devices.

Simple maintenance

• The management port, fans, and power modules are on the front panel, which facilitates device maintenance.
• Data ports are located at the rear, facing servers. This simplifies cabling.
