Product Characteristics
High-density 40GE Access
The CE7800 provides a switching capacity of 2.56 Tbit/s in a 1U form factor, with a forwarding performance of 1,440 Mpps, supporting L2/L3 line-speed forwarding. It offers a maximum of 32 x 40GE QSFP+ ports, functioning as a core or aggregation switch for data center or campus networks. Each QSFP+ port can be split into four 10GE SFP+ ports, offering network flexibility. CE7800 switches can interoperate with CE12800/6800/5800 switches to establish a non-blocking network platform.
Highly Reliable, High-performance Stacking
The CE7800 supports an industry-leading 16-member stack system, allowing up to 512 x 40GE access ports for high-density server access in data centers. Multiple switches within a stack system are virtualized into a single logical device, facilitating the creation of a scalable and manageable data center network platform. This stacking architecture separates the control plane from the data plane, eliminating single-point failures and significantly enhancing system reliability. The CE7800 also supports long-distance stacking, utilizing service ports as stack ports to establish stack systems across different racks or even over long distances. Service and stack bandwidths can be allocated based on network scale for more efficient resource utilization.
Vertical Virtualization Simplifies Management
The CE7800 supports Super Virtual Fabric (SVF), which virtualizes multiple physical switches (homogeneous or heterogeneous) into a single logical switch, simplifying network management and improving reliability. SVF enables vertical extension of heterogeneous switches, virtualizing multiple leaf switches into remote cards of the spine switch. This simplifies cabling in equipment rooms and device management, with the CE7800 acting as the spine switch. Huawei's SVF is the first in the industry to support local forwarding for leaf switches, enhancing forwarding efficiency and reducing network delay for mainstream horizontal traffic in data centers.
Large-scale Routing Bridge, On-demand Scalability
The CE7800 supports the IETF Transparent Interconnection of Lots of Links (TRILL) protocol. A TRILL network can accommodate over 500 nodes, enabling flexible service deployments and large-scale Virtual Machine (VM) migrations. TRILL utilizes a routing mechanism similar to IS-IS and employs a limited Time-to-Live (TTL) value in packets to prevent Layer 2 loops, thereby improving network stability and convergence speed. On a TRILL network, data flows are forwarded rapidly using Shortest Path First (SPF) and Equal-cost Multi-path (ECMP) routing, avoiding suboptimal path selection issues found in STP and achieving 100% link bandwidth efficiency. The CE7800's support for TRILL-based Layer 2 equal-cost paths enhances load balancing capabilities, and its fat-tree architecture improves scalability.
Converged Enhanced Ethernet, Data, Storage, and Computing Traffic over One Network
The CE7800 supports Fibre Channel over Ethernet (FCoE), allowing storage, data, and computing services to be transmitted over a single network, reducing network construction and maintenance costs. It also supports centralized FCoE/FC gateway deployment for simpler network O&M. Features like Priority-based Flow Control (PFC), Enhanced Transmission Selection (ETS), and Data Center Bridging eXchange (DCBX) ensure lossless transmission, providing low latency and zero packet loss for FC storage and high-speed computing services.
Fast VM Migration, Policy Mobility
In conjunction with Huawei's Agile Controller, the CE7800 allows for dynamic network policy deployment and supports online VM migration. Agile Controller delivers network policies via high-speed RADIUS interfaces, offering VM migration speeds 10 to 20 times faster than other industry platforms, facilitating large-scale VM migrations. Agile Controller is built on open APIs and is compatible with major virtualization platforms, including VMware.
Programmable Network Device, Flexible Customization
The CE7800 integrates the Open Programmability System (OPS) within the VRP8 software platform, enabling control plane programmability. OPS provides open APIs that can be integrated with mainstream cloud platforms and third-party controllers, allowing for flexible service customization and automated management. Users and developers can leverage these open APIs to develop and deploy specialized network management policies for rapid service function extension, automatic deployment, and intelligent management, reducing operational costs. OPS facilitates seamless integration of data center services and networks, supporting a service-oriented, Software-Defined Network (SDN).
Virtualized Gateway Achieves Fast Service Deployment
The CE7800 can function as a high-performance hardware gateway for overlay networks (VXLAN) when used with mainstream virtualization platforms, supporting over 16 million tenants. It can connect to cloud platforms via open APIs for unified software and hardware network management. This capability enables fast service deployment without altering existing customer networks, thereby protecting investments.
Zero-Configuration Deployment, Automatic O&M
The CE7800 supports Zero Touch Provisioning (ZTP), allowing automatic acquisition and loading of version files from a USB flash drive or file server, eliminating the need for on-site configuration. ZTP reduces labor costs and improves device deployment efficiency. It provides built-in scripts accessible through open APIs, enabling data center personnel to use familiar programming languages like Python for unified network device configuration. ZTP decouples configuration time from device quantity and distribution, enhancing service provisioning efficiency.
Flexible Airflow Design Saves Energy
The CE7800 features a flexible front-to-back/back-to-front airflow design that separates cold and hot air channels, meeting the heat dissipation requirements of data center equipment rooms. Airflow direction can be adjusted by using different fans and power modules. Redundant power modules and fans ensure uninterrupted service transmission. The switches incorporate energy-saving chips and measure system power consumption in real-time, dynamically adjusting fan speeds to reduce O&M costs and promote greener data centers.
Clear Indicators, Simple Maintenance
The CE7800 is equipped with clear port indicators that display port status and speeds, including the states of derived 10GE ports from 40GE ports. State and stack indicators on both front and rear panels allow for maintenance from either side. Remote positioning indicators can be activated to easily locate specific switches within a densely populated equipment room. Maintenance is simplified as the management port, fans, and power modules are located on the front panel, while data ports are at the rear, facing the servers, simplifying cabling.
