CE6850 series can work with CloudEngine 16800 or CloudEngine 12800 switches to build an elastic, virtualized, high-quality fabric that meets the requirements of cloud-computing data centers.

CE6850 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 be used as aggregation or core switches for enterprise campus networks.

CloudEngine 6857-48S6CQ-EI switches provide 48 x 10GE SFP+ ports, 6 x 100GE QSFP28 ports or 6 x 40GE QSFP+ ports.

Product Characteristics

High-Density 10GE Access

• CloudEngine 6850 series provide 48 x 10GE ports, high-density 10GE ports among 1 U ToR switches, allowing for highdensity 10GE server access.
• CloudEngie 6850 series have a maximum of six 100GE QSFP 28 or 40GE QSFP+ ports. Each QSFP28 or QSFP+ port can be used as four 10GE SFP+ ports, providing flexibility in networking. The uplink QSFP28 or 40GE QSFP+ ports can be connected to CloudEngine 16800 or CloudEngine 12800 switches to build a non-blocking network platform.

Inter-device Link Aggregation, High Efficiency and Reliability

• CloudEngine 6850 series support multichassis 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 system all work in active state to share traffic and back up each other, enhancing system reliability.
• Switches in an M-LAG system 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, VXLAN, and IP networks, allowing for flexible networking.
• With comprehensive inter-device link aggregation technology, the device networking coupling relationship evolves from stacking at the control plane to the use of M-LAG and then finally to coupling-free M-LAG Lite. This achieves active-active server access and zero interruption of services when upgrading switches.

Virtualized Hardware Gateway, Enabling Quick Deployment

• CloudEngine 6850 series can work with the industry's mainstream virtualization platforms and acts a hardware gateway on an overlay network (VXLAN). The virtualization function protects investments by ensuring services can be deployed quickly without requiring network changes.
• CloudEngine 6850 series can connect to a cloud platform through open APIs, facilitating the unified management of virtual and physical networks.
• The hardware gateway deployment enables fast service deployment without changing the customer network, providing investment protection.
• CloudEngine 6850 series support Border Gateway Protocol - Ethernet VPN (BGP-EVPN), which can run as the VXLAN control plane to simplify VXLAN configuration within and between data centers.

Standard Interfaces, Enabling Openness and Interoperability

• CloudEngine 6850 series support NETCONF and can work with Huawei iMaster NCE-Fabric.
• CloudEngine 6850 series support Ansible-based automatic configuration and open-source module release, expanding network functions and simplifying device management and maintenance.
• CloudEngine 6850 series can be integrated into mainstream SDN and cloud computing platforms flexibly and quickly.

ZTP, Implementing Automatic O&M

• CloudEngine 6850 series support Zero Touch Provisioning (ZTP). ZTP enables the CloudEngine 6850 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 6850 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.

iMaster NCE-based Simplified Network Deployment

• CloudEngine 6850 series switches can interconnect with iMaster NCE-Fabric through standard protocols such as NetConf and SNMP to implement network automatic management and control, providing more efficient and intelligent operation methods, simplifying network management, and reducing the OPEX.

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

• CloudEngine 6850 series use a strict front-to-back/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 6850 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 40GE/100GE port indicators can show the states of all ports derived from the 40GE/100GE ports. State and stack indicators on both the front and rear panels enable users to maintain the switch from either side.
• CloudEngine 6850 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.
