Data Center Switch Features

Characteristics

High-density 40GE Access

• The CE7800 provides 2.56 Tbit/s switching capacity in a 1 U ToR, forwarding performance of 1,440 Mpps, and supports L2/L3 line-speed forwarding.
• The CE7800 provides a maximum of 32*40GE 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 10GE SFP+ ports, providing 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*40GE access ports that provide high-density server access in a data center.
  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 or different racks, and even 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 Layer 2 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 suboptimal path selection problem in STP and increase link bandwidth efficiency to 100 percent.
• The CE7800 supports TRILL-based Layer 2 equal-cost paths, greatly improving links' load balancing capabilities. The network has a fat-tree architecture that enhances expansion.

Converged Enhanced 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: 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 nCenter automated network management platform to permit network policies to be dynamically deployed on the CE7800. nCenter also supports online VM migration.
• nCenter 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.
• nCenter 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 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, 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 (NVGRE/VXLAN), the CE7800 can support more than 16M 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 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.

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 40GE port indicators can show the state of all the 10GE ports derived from the 40GE 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.
