Network-Wide Reliability, Ensuring Zero Service Interruptions

• The CloudEngine 8800 series switches 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 can be upgraded independently. During the upgrade, other switches in the system take over traffic forwarding to ensure uninterrupted services.
• With the comprehensive inter-device link aggregation technology, the device networking coupling relationship evolves from stacking at the control plane to the use of M-L AG and then finally to coupling-free M-LAG Lite. This achieves active-active server access and high reliability during switch upgrage.

Programmable Network Device, Flexible Customization

• The CloudEngine 8800 series switches use the Open Programmability System (OPS) embedded in the VRP8 software platform to provide programmability at the control plane.
• The OPS provides open APIs. APIs can be integrated with mainstream cloud platforms (including commercial and open cloud platforms) and third-party controllers. The OPS enables services to be flexibly customized and provides automatic management.
• 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.
• The OPS provides seamless integration of data center service and network in addition to a service-oriented, softwaredefined networking (SDN).

Virtualized Gateway Achieves Fast Service Deployment

• The CloudEngine 8800 series switches can work with a mainstream virtualization platform. As the high performance, hardware gateway of an overlay network (VXLAN), the CloudEngine 8800 series switches can support more than 16 million tenants.
• The CloudEngine 8800 series switches can connect to a cloud platform through an open API to provide unified management of software and hardware networks.
• This function implements fast service deployment without changing the customer network. It also protects customer investments.

Standard Interfaces, Enabling Openness and Interoperability

• CloudEngine 8800 series support NETCONF and can work with Huawei iMaster NCE-Fabric.
• CloudEngine 8800 series support Ansible-based automatic configuration and open-source module release, expanding network functions and simplifying device management and maintenance.
• CloudEngine 8800 series can be integrated into mainstream SDN and cloud computing platforms flexibly and quickly.

ZTP, Implementing Automatic O&M

• The CloudEngine 8800 series switches support Zero Touch Provisioning (ZTP). ZTP enables the CloudEngine 8800 to automatically obtain and load version files from a USB flash drive or file server, freeing network engineers from onsite configuration or deployment. ZTP reduces labor costs and improves device deployment efficiency.
• ZTP provides built-in scripts for users through open APIs. Data center personnel can use the programming language they are familiar with, such as Python, to provide unified configuration of network devices.
• ZTP decouples configuration time of new devices from device quantity and area distribution, which improves service provisioning efficiency.

Intelligent Lossless DCN, Improving Reliability of High-Performance Computing

• In a distributed system, RoCE technology becomes the mainstream. To ensure the throughput and meet strict requirements on packet loss, Huawei ultra-fast Ethernet provides forwarding capabilities with high throughput, high reliability, and low latency for the distributed system, which is 25% lower than the average latency in the industry.
• The CloudEngine 8861-4C-EI/8850-64CQ-EI switches support Virtual Input Queue (VIQ) technology. It uses Huawei customized algorithm to customize virtual queues based on services, implementing refined management. It pre-determines uplink and downlink queue congestion to eliminate packet loss.
• The CloudEngine 8861-4C-EI/8850-64CQ-EI switches use fast CNP and dynamic ECN to pre-determine network congestion and provide fast feedback, reducing retransmission and throughput decrease caused by packet loss on a network. This keeps a low queue delay while ensuring the throughput.
• The CloudEngine 8861-4C-EI/8850-64CQ-EI switches provide dynamic load balancing (DLB) based on the ECMP group or LAG.
• The CloudEngine 8861-4C-EI/8850-64CQ-EI switches support analyzing RoCE flow KPIs, including the flow path, RTT, throughput, packet loss rate, abnormal sessions, and top sessions, and display the RoCE network topology of each node and ECN thresholds of Huawei AI Fabric. In this way, more proper network parameters can be configured and network faults can be quickly located, improving configuration and O&M efficiency.

FabricInsight-based Intelligent O&M

• The CloudEngine 8800 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 8800 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, High Energy Efficiency

Flexible front-to-back/back-to-front airflow design

• The CloudEngine 8800 series switches use a front-to-back/back-to-front airflow design that isolates cold air channels from hot air channels. This design meets heat dissipation requirements in 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

• The CloudEngine 8800 series switches have energy-saving chips and can measure system power consumption in real time. 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 port indicators can show the states of all ports derived from the 40GE ports.
• State and stack indicators on both the front and rear panels enable users to maintain the switch from either side.
• The CloudEngine 8800 series switches support remote positioning. Operators can turn on remote positioning indicators on the switches they want to maintain, so that they can find switches easily 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.
