H3C S6800 Series Data Center Switches

Flexible port combination

H3C S6800-2/4C support various types of interface cards, realize mixed configuration of high-density 10GE optical and copper port / 40GE / 100GE/MACsec/FC interface.

For S6800-4C， It can support up to 96 10GE ports and 8 40GE ports, or 32 40GE high-speed interfaces.

Data Center-Oriented Features

The switch supports abundant data center features, including:

H3C S6800 series switch supports VXLAN (Virtual eXtensible LAN), which provides two major benefits, higher scalability of Layer 2 segmentation and better utilization of available network paths.

H3C S6800 series switch supports MP-BGP EVPN (Multiprotocol Border Gateway Protocol Ethernet Virtual Private Network) which can run as VXLAN control plane to simplify VXLAN configuration, eliminate traffic flooding and reduce full mesh requirements between VTEPs via the introduction of BGP RR.

H3C S6800 series switch support Fiber 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.

H3C S6800-2C/4C switch support Fiber Channel interface card, the ports can be switched to FC port to interoperate with FC SAN.

H3C S6800 series switch support 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.

H3C S6800 series switch support TRILL (Transparent Interconnection of Lots of Links). TRILL is an innovative technology that changes the traditional way to build data center networks. By using TRILL technology, S6800 series switch becomes the ideal choice to build a large, high-performance, and scalable cloud data center networks that support live virtual machines.

H3C Distributed Resilient Network Interconnection (DRNI)

H3C S6800 series switch support DRNI, which enables links of multiple switches to aggregate into one to implement device-level link backup. DRNI is applicable to servers dual-homed to a pair of access devices for node redundancy.

Streamlined topology: DRNI simplifies the network topology and spanning tree configuration by virtualizing two physical devices into one logical device.

Independent upgrading: The DR member devices can be upgraded independently one by one to minimize the impact on traffic forwarding.

High availability: The DR system uses a keepalive link to detect multi-active collision to ensure that only one member device forwards traffic after a DR system splits.

RoCE (RDMA over Converged Ethernet)

Remote Direct Memory Access (RDMA) directly transmits the user application data to the storage space of the servers, and uses the network to fast transmit the data from the local system to the storage of the remote system. RDMA eliminates multiple data copying and context switching operations during the transmission process, and reduces the CPU load.

RoCE supports RDMA on standard Ethernet infrastructures. H3C S6800 switch support RoCE and can be used to build a lossless Ethernet network to ensure zero packet loss.

RoCE include the following key features, include PFC(Priority based Flow Control), ECN(Explicit Congestion Notification), DCBX(Data Center Bridging Capability Exchange Protocol), ETS(Enhanced Transmission Selection).

Powerful SDN capacity

H3C S6800 series switch adopt the next-generation chip with more flexible OpenFlow, more resources and accurate ACL matching, which greatly improves the software-defined network (SDN) capabilities and meet the demand of data center SDN network.

H3C S6800 series switch support standard OpenFlow protocol, which can be integrated and managed by H3C VCFC controller or H3C cloud or mainstream cloud platforms or a third-party controller to support flexible network customization and automated management. Users and third-party controllers can use standard interfaces to develop and deploy a dedicated network management strategy for rapid business deployment, functional expansion, and intelligent device management.

MACsec

H3C S6800 series switch supports hardware level encryption technology MACsec (802.1ae), which is an industry-standard security technology that provides secure communication for all traffic on Ethernet links. Compared with traditional application-based software encryption technology, MACsec provides point to-point security on Ethernet links between directly connected nodes and is capable of identifying and preventing most security threats.

Outstanding security control policies

H3C S6800 series switch supports AAA, RADIUS and user account based authentication, IP, MAC, VLAN, port-based user identification, dynamic and static binding; when working with the H3C iMC platform, it can conduct real time management, instant diagnosis and crackdown on illicit network behavior.

H3C S6800 series switch supports enhanced ACL control logic, which enables an enormous amount of inbound and outbound ACL, and delegate VLAN based ACL. This simplifies user deployment process and avoids ACL resource wastage. S6800 switch series can also take advantage of Unicast Reverse Path Forwarding (uRPF). When the device receives a packet, it will perform the reverse check to verify the source address from which the packets are supposedly originated, and will drop the packet if such path doesn’t exist. This will curb the increasingly common originating address spoofing.

Flexible choice of airflow

To cope with data center cooling aisle design, the H3C S6800 series switch comes with flexible airflow design, which features bi-cooling aisles in the front and back. Users may also choose the direction of airflow (from front to back or vice versa) by selecting a different fan tray.

Multiple Reliability

H3C S6800 series switch provides multiple reliability protection at both switch and link levels. With overcurrent, overvoltage, and overheat protection, all models have a redundant pluggable power module, which enables flexible configuration of AC or DC power modules based on actual needs. The entire switch supports fault detection and alarm for power supply and fan, allowing fan speed to change to suit different ambient temperatures.

Excellent manageability

H3C S6800 series switch provides a rich management interface, including console, external network and USB. Management protocols such as SNMPv1/v2/v3 are supported aside from iMC Management Console. The network administrator may activate control through CLI, TELNET, SSH, SNMP, RESTful API, which gives maximum flexibility in accessing and managing the device. The administrator may also choose SSH2.0 and SSL encryption to shield the management session.

Performance and scalability

The typical data center application is an EVPN-VxLAN design,S125G-AF or S125X-AF swithes work as spine or spine/border, S68XX series work as leaf and border or ED. From this design ,the usrs can get a non-blocking large L2 system.
