High-Density GE Access, Leading Performance

• Each CE6800 switch provides a switching capacity of 1.28Tbps, which is the industries highest performance (1U TOR). It has a 960Mpps forwarding performance and supports L2/L3 line-speed forwarding.
• CE6800 provides a maximum of 64*10GE ports, which is the industries highest 10GE port density (1U TOR). This super-high port density meets the requirement for high-density 10GE server access.
• CE6800 has 4*40GE QSFP+ ports. Each QSFP+ port can be used as 4*10GE ports, allowing flexible network deployment. Through the 40GE QSFP+ ports, CE6800 switches can work with CE12800 switches to build a non-blocking network platform.



Highly Reliable Stacking, Superior Capacity

• The industries first 16-member stack system:
  A stack system of 16 member switches has more than 768*10GE access ports to support 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 and 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:
  CE6800 switches can use service ports as stack ports. A stack system can be established by switches in the same rack or different racks even over long distances.
• Service bandwidth and stack bandwidth can be allocated based on the network scale so that network resources can be used more efficiently.



Large-Scale Routing Bridge, Flexible Deployment

• All CloudEngine series switches support IETF TRILL protocol and can constitute a large Layer 2 TRILL network with GE/10GE servers. The TRILL network can contain more than 500 nodes, allowing flexible service deployments and large-scale VM migrations.
• The TRILL protocol uses a routing mechanism similar to IS-IS and sets a limited 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 tree (SPF) and equal-cost multipath (ECMP) routing. SPF and ECMP avoid the suboptimal path selection problem in STP and increase the link bandwidth efficiency to 100%.
• Each CE6800 switch supports up to 16 TRILL-based Layer 2 equal-cost paths, greatly improving load balancing capabilities of links. The network has fat-tree architecture to support smooth expansion.



Converged Enhanced Ethernet, Data and Storage Traffic over One Network

• The CE6800 series supports Fibre Channel over Ethernet (FCoE), which allows the storage service, data service and computing service to be transmitted on one network, reducing costs of network construction and maintenance.
• The CE6800 series supports centralized FCoE/FC gateway deployment. This deployment, the Ethernet network is compatible with the FC SAN, but Ethernet access devices do not participate in computing of the FC protocol, making network O&M simpler.
• The CE6800 series supports various features to ensure lossless transmission, such as 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 the FC storage service and high-speed computing service.



Automated Service Deployment, Fast VM Migration

• The next-generation automated NMS nCenter can work with the VM management platform to dynamically deploy network policies for VMs on CE6800 switches. This implements fast in-service migration of VMs.
• nCenter delivers network policies through high-speed RADIUS interfaces so that VMs can migrate at a speed 10 to 20 times the industry average.
• nCenter is developed based on open APIs and is compatible with all major virtualized platforms.



Changeable Air Flow Direction, Innovative Energy-Saving Technologies

• Flexible front-to-rear/rear-to-front ventilation channel design:
  The CE6800 uses a straight ventilation channel design that separates cold air flows from hot air flows to improve heat dissipation efficiency. This is the best ventilation channel design for data center equipment rooms.
  Air can flow from front to rear or rear to front in ventilation channels when different fans and power modules are used.
  Power modules and fans can be configured in redundancy mode to ensure uninterrupted service transmission.
• Innovative energy-saving technologies:
  The CE6800 has innovative energy-saving chips and can measure system power consumption in real time. The fan speed can be adjusted dynamically based on system consumption. These energy-saving technologies reduce O&M costs and contribute towards a greener data center.

Clear Indicators, Simple Maintenance

• Clear indicators:
  Port indicators show the port status and port speeds clearly. The 40GE port indicators can show the states 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.
  CE6800 switches support remote positioning. Operators can turn on the remote positioning indicators on the switches they want to maintain, so that they can find these devices 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.

Application in a Data Center

On a typical data center network, CE12800 switches work as core switches and CE6800/CE5800 switches work as TOR switches. CE6800/CE5800 switches connect to CE12800 switches through 40GE/10GE ports. The CE12800 and CE6800/CE5800 switches use the TRILL protocol to build a non-blocking Layer 2 network, which allows large-scale VM migrations and flexible service deployments.

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

Application on a Campus Network

CE6800 switches can be used as aggregation or core switches on a campus network. Its high-density line-speed 10GE ports and high stacking capability can meet the ever-increasing demand for network bandwidth. CE6800 switches are cost-effective campus network switches, thanks to their abundant service features and innovative energy-saving technologies.

On a typical campus network, two CE12800 switches are virtualized into a logical core switch using the CSS technology. Multiple CE6800 switches at the aggregation layer form a logical switch using the iStack technology. The CSS and iStack technologies improve network reliability and simplify network management. At the access layer, CE5800 switches are stacked using iStack technology to provide high-densities of line-speed ports.

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