The CE series data center switches help enterprises and carriers build a non-blocking switching platform that provides access to tens of thousands of 10 GE/GE servers. This platform has the advantage of elastic, virtualized, and high-quality fabrics that help build a stable, yet agile services network. The switches provide industry-leading performance, full virtualization, many data center features, and an advanced architecture.

Elastic CloudEngine

The elastic network will support business growth and development for the next 10 years: CE switches can implement a non-blocking switching network that supports data center server evolution across four generations - from GE, 10 GE, 40 GE, and, finally, to 100 GE. With this non-blocking switching platform, customers do not need to upgrade their networks to meet requirements for 40 GE or even 100 GE access.

World's highest-performance core switch: The CE12800 provides 4 Tbit/s bidirectional bandwidth per slot (scalable to 10 Tbit/s) and 64 Tbit/s switching capacity (scalable to more than 160 Tbit/s). The CE12800 supports a variety of high-speed line cards: 12*100GE, 24*40GE, and 96*10GE. Each switch can provide as many as 192*100GE, 384*40GE, or 1,536*10GE line-speed ports. The high capacity and port density make the CE12800 an industry leader.

40 GE uplink ports on all Top-of-Rack (ToR) switches: the CE6800 and CE5800 provide super-high densities of 10 GE, and GE access ports. The entire CE6800/CE5800 series provides 40 GE uplink ports with the highest forwarding performance in the industry.

Highest server access capability in the industry: using a two-layer flat network architecture consisting of core and ToR access switches, the CE12800 leads the world in server access. The CE12800 can combine with the CE7800/CE6800/CE5800 using 40 GE ports to build a network that provides access for up to 18,000 10 GE servers or 70,000 GE servers.

Virtualized Fabric

Comprehensive network virtualization: The CE series uses Virtual System (VS) and Cluster Switch System (CSS)/Super Virtual Fabric (SVF) technologies to flexibly adjust network boundaries that meet requirements for network virtualization. The switches use Transparent Interconnection of Lots of Links (TRILL) and nCenter technologies to support service and server virtualization. The switches use Ethernet Virtual Network (EVN) technology to optimize Layer 2 interconnection between data centers and implement service resource sharing across data centers.

VS for on-demand resource sharing: The CE12800 enables one switch to be virtualized into as many as sixteen logical switches. This 1:16 ratio permits one core switch to manage services for multiple parts of an enterprise (such as production, office, and DMZ) or for multiple tenants. VS technology improves efficiency of device usage and reduces network construction costs while maintaining high security.

SVF/CSS simplifies network management: CE series switches support SVF/CSS technology, which can virtualize multiple homogeneous or heterogeneous physical switches into one logical switch to improve network management and improve reliability. CSS is the industry-leading core switch cluster technology that virtualizes core devices horizontally into one logical switch. SVF implements vertical extension of heterogeneous switches and virtualizes multiple leaf switches into remote cards of the spine switch, making it easier to cable equipment rooms and manage devices. Huawei's SVF exclusively implements local forwarding of leaf switches. When horizontal traffic is the mainstream traffic in a data center, SVF improves forwarding efficiency and reduces network delay.

Innovative CSS + VS synergy technology: The CE12800 combines CSS and VS technologies to turn a network into a resource pool so that network resources can be allocated on demand. This on-demand resource allocation is ideal for the cloud-computing service model.

Large-scale routing bridge to support flexible service deployment: All CE series switches support TRILL, a standard IETF protocol. The TRILL protocol helps implement a large Layer 2 network with more than 500 nodes. This network enables flexible service deployment and VM migration that are free from restrictions imposed by physical locations. A TRILL network can use 10 GE/GE servers.

nCenter enables automatic migration of VMs: nCenter is an automated management system for virtualized data centers. It automatically delivers network configurations to devices when VMs migrate. Additionally, nCenter provides high-speed RADIUS interfaces to increase VM migration speeds by 10 to 20 times the industry average.

EVN implements resource sharing across data centers: The CE12800 supports EVN technology. EVN implements inter-data-center Layer 2 interconnection across the IP WAN, integrates multiple data centers into a super-large IT resource pool, and enables VMs to migrate across data centers. EVN supports Layer 2 interconnection among a maximum of 32 data centers, 5 times more than the industry average.

Agile CloudEngine

Fully programmable, agile switch: Huawei CE series switches enable programmability in the forwarding and control planes. Huawei's Ethernet Network Processor (ENP) card provides programmability in the forwarding plane, extending network functions. The Open Programmability System (OPS) provides programmability in the control plane and various open APIs to connect to mainstream cloud platforms and third-party controllers, implementing an open and controllable network.

ENP supports service innovation: The CE12800 is based on Huawei's innovative ENP programmable chip. The high-performance, programmable, 480 Gbit/s ENP card is able to define network functions through software and extend network functions. When new services are provisioned, there is no need to replace the hardware. In addition, service provisioning is shortened from two years to three months.

OPS provides service customization: CE series switches use the OPS module embedded in the VRP8 software platform to provide programmability in the control plane. The OPS provides open APIs for users or third-party developers. 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 supports automatic management. The OPS provides seamless integration of the data center service and network in addition to a service-oriented, software-defined network.

Virtualized gateway achieves fast service deployment: CE series switches can work with a mainstream virtualization platform. As the high-performance, hardware gateway of an overlay network (NVGRE/VXLAN), a CE series switch can support more than 16M tenants. This function implements fast service deployment without changing the customer network. It also protects customer investments. In this application, the CE series switch can connect to the cloud platform through an open API to provide unified management of software and hardware networks.

ZTP implements zero-configuration deployment: CE series switches support Zero Touch Provisioning (ZTP). ZTP enables a CE switch 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 increases device deployment efficiency. ZTP provides built-in scripts for users through open APIs. Data center users can use the programming language they are familiar with, such as Python, to provide unified configuration of network devices.

High-Quality CloudEngine

High-reliability network designed for data centers: The CE12800 guarantees industrial-grade reliability and uses a redundant design for both hardware and software to ensure service continuity in data centers. The CE12800's industry-leading, non-blocking switching architecture ensures non-stop services. Additionally, CE series switches can implement a lossless, low-latency Ethernet network, which provides unified, lossless transmission for high-value services. In addition, Huawei CE series switches support a strict front-to-back airflow design, which meets data centers' heat dissipation requirements and greatly reduces equipment room power consumption.

Non-stop switching core supports service continuity: The CE12800's components (MPUs, SFUs, CMUs, power supplies, and fans) use a hot-backup design. Three major buses (monitoring, management, and data) work redundantly, ensuring the high reliability of core nodes. By using Huawei's next-generation VRP8 software platform, the CE12800 can support In-Service Software Upgrade (ISSU) technologies, which ensure continuity of services during service switching and in-service upgrades.

Non-blocking switching architecture to ensure non-stop services: The CE12800’s non-blocking switching architecture features an orthogonal switch fabric design, Clos architecture, cell switching, Virtual Output Queuing (VoQ), and a super-large buffer. The orthogonal switch fabric greatly improves system bandwidth and evolution capabilities and enables switching capacity to scale to more than 100 Tbit/s. The cell-switching-based Clos architecture supports dynamic routing, load balancing, and expansion of the flexible switch fabric. The VoQ mechanism, together with the super-large buffer on inbound interfaces (as much as 18 GB per line card), provides fine-grained QoS, implements unified service scheduling, sequenced forwarding, and non-blocking switching.

Lossless switching network ensures unified service transmission: The CE series' Data Center Bridging (DCB) ensures low latency and zero packet loss for Fibre Channel (FC) storage and high-speed computing services. The CE12800 core switch has 2 us latency, one-third the industry average, making the CE12800 appropriate for latency-sensitive, high-value services such as online video and games. The CE series can implement a lossless, low-latency Ethernet network to transmit storage services, computing services, and data services, while reducing costs of network construction and maintenance.

Strict front-to-back airflow design greatly reduces power consumption: CE series switches use a strict front-to-back airflow design, which meets data centers’ strict heat dissipation requirements. The CE12800 core switch uses the front-to-back airflow design, and line cards and the switching network use independent airflow channels, which solve the problems of mixing hot and cold air and cascade heating, and effectively reduce energy consumption in equipment rooms. The CE7800/CE6800/CE5800 ToR switches use a flexible front-to-back or back-to-front airflow design for a changeable airflow direction.
