Model and appearance	Description
CE7850-32Q-EI	32 x 40 GE QSFP+ ports

Product Characteristics

High-density 40 GE access

The CE7800 provides 2.56 Tbit/s switching capacity in a 1U TOR, forwarding performance of 1,440 Mpps, and supports L2/L3 line-speed forwarding

The CE7800 provides a maximum of 32 x 40 GE QSFP+ ports and can function as the core or aggregation switch on a data center or campus network

The QSFP+ port can be used as four 10 GE SFP+ ports to provide a flexible network. CE7800 switches can work with CE12800/6800/5800 switches to build a non-blocking network platform

Highly reliable, high-performance stacking

The industry’s first 16-member stack system

A stack system of 16 member switches has a maximum of 512 x 40 GE access ports for high-density server access

Multiple switches in a stack system are virtualized into one logical device, making it possible to build a scalable, easy-to-manage data center network platform

A stack system separates the control plane from the data plane. This eliminates the risk of single-point failures and greatly improves system reliability

Long-distance stacking

The CE7800 can use service ports as stack ports. A stack system can be established with switches in the same rack, different racks, and over long distances

Service and stack bandwidths can be allocated based on the network's scale so that network resources can be used more efficiently

Large-scale routing bridge, on-demand scalability

The CE7800 supports the IETF Transparent Interconnection of Lots of Links (TRILL) protocol. A TRILL network can contain more than 500 nodes, enabling flexible service deployments and large-scale Virtual Machine (VM) migrations

The TRILL protocol uses a routing mechanism similar to IS-IS and sets a limited Time-to-Live (TTL) value in packets to prevent L2 loops. This significantly improves network stability and speeds up network convergence

On a TRILL network, all data flows are forwarded quickly using Shortest Path First (SPF) and Equal-Cost Multi-Path (ECMP) routing. SPF and ECMP avoid the sub-optimal path selection problem in STP and increase link bandwidth efficiency to 100 percent

The CE7800 supports TRILL-based L2 equal-cost paths to improve links’ load balancing capabilities. The network has a fat-tree architecture that makes expansion easier

Converged Ethernet, data, storage, and computing traffic over one network

The CE7800 supports Fibre Channel over Ethernet (FCoE), which permits storage, data, and computing services to be transmitted on one network, reducing the costs of network construction and maintenance

The CE7800 supports centralized FCoE/FC gateway deployment, which makes network O&M simpler

Various CE7800 features ensure lossless transmission, including Priority-Based Flow Control (PFC), Enhanced Transmission Selection (ETS), and Data Center Bridging eXchange (DCBX). These features ensure low latency and zero packet loss for FC storage and high-speed computing services

Fast VM migration, policy mobility

The CE7800 works with Huawei’s Agile Controller to permit network policies to be dynamically deployed. The Agile Controller also supports online VM migration

The Agile Controller delivers network policies through high-speed RADIUS interfaces. Its online VM migration is 10 to 20 times the rate of other industry platforms, enabling large-scale VM migrations

The Agile Controller is based on open APIs and is compatible with all major virtualization platforms including VMware

Programmable network device, flexible customization

The CE7800 uses the Open Programmability System (OPS) embedded in the VRP8 software platform to provide programming 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, Software-Defined Network (SDN)

Virtualized gateway achieves fast service deployment

The CE7800 can work with a mainstream virtualization platform. As the high-performance hardware gateway of an overlay network (VXLAN/NVGRE), the CE7800 can support more than 16 million tenants

The CE7800 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

Zero-configuration deployment, automatic O&M

The CE7800 supports Zero-Touch Provisioning (ZTP). ZTP enables the CE7800 to automatically obtain and load version files from a USB flash drive or file server, freeing network engineers from on-site 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

Flexible airflow design saves energy

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

The CE7800 uses 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 when different fans and power modules are used

Redundant power modules and fans can be configured to ensure uninterrupted service transmission

Innovative energy-saving technologies

The CE7800 has 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, simple maintenance

Clear indicators

Port indicators clearly show port status and port speeds. The 40 GE port indicators can show the state of all the 10 GE ports derived from the 40 GE ports

State and stack indicators on both the front and rear panels enable operators to maintain the switch from either side.

The CE7800 supports 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

Deployment Scenarios

Data center applications

On a typical data center network, CE12800/CE7800 switches work as core switches and CE6800/CE5800 switches work as TOR switches. CE6800/CE5800 switches connect to CE12800/CE7800 switches through 40 GE/10 GE ports. The CE12800/CE7800 and CE6800/CE5800 switches use the TRILL protocol to build a non-blocking L2 network that allows large-scale VM migrations and flexible service deployments.

Note: The TRILL protocol can be also used on campus networks to support flexible service deployments in different service areas.

Campus network applications

The CE7800 can be used on a campus network. Its high-density, line-speed 40 GE ports and high stacking capability can meet the ever-increasing demand for network bandwidth. CE7800 switches are cost-effective campus network switches thanks to their extensive service features and innovative energy-saving technologies.

On a typical campus network, two CE12800/CE7800 switches are virtualized into a logical core switch using CSS or iStack technology. Multiple CE6800 switches at the aggregation layer form a logical switch using iStack technology. CSS and iStack improve network reliability and simplify network management. At the access layer, CE5800 switches are virtualized with SVF to provide high-density line-speed ports.

Note: iStack technology is also widely used in data centers to facilitate network management.
