H3C S6805 high-density intelligent switch series is developed for data centers and cloud computing networks. It provides powerful hardware forwarding capacity and abundant data center features. The switch supports modular power modules and fan trays. By using different fan trays, the switch can provide field-changeable airflows.
The switch is perfectly matched for high density 10GE, it can also operate as a TOR access switch on an overlay or integrated network.
The S6805 switch series has two models:
S6805-54HF: The switch provides 48 × 10G SFP Plus ports, 6 × 100G QSFP28 ports
S6805-54HT: The switch provides 48 × 10G Base-T ports, 6 × 100G QSFP28 ports
High port density and powerful forwarding capacity
The switch offers high-density 100G/40G/10G ports and a forwarding capacity as high as 4 Tbps, it can provide high-density 10G server access in high-end data centers
Flexible programmability
The switch uses industry-leading programmable switching chips that allow users to define the forwarding logic as needed.
Users can develop new features that meet the evolving trend of their networks through simple software updates.
Powerful visibility
With the rapid development of data center, the scale of the data center expands rapidly; reliability, operation and maintenance become the bottleneck of data center for further expansion. H3C S6805 switch series conform to the trend of automated data operation and maintenance, and support visualization of data center. H3C S6805 switch series can send real-time resources information, statistics and alarm of RDMA information to the data center operation and maintenance platform through ERSPAN and GRPC protocols. This can allow the operation and maintenance center to perform real-time analysis in order to achieve network quality tracing, troubleshooting, risk warning and system optimization and etc. Visualization can even adjust network configuration automatically and reduce network congestion which makes it possible to move to automated data center operation and maintenance.
Powerful SDN capacity
H3C S6805 switch series adopt the next-generation chip with more flexible Openflow FlowTable, 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 S6805 switch series support standard Openflow protocol, which can be integrated and managed by H3C 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.
Abundant data center features
The switch supports abundant data center features, including:
FCoE technology leverages Ethernet packet to carry FC packets. This means FC SAN and Ethernet LAN network can share the same network infrastructure, which is a good solution to solve the problems of coexistence between different types of network. S6805 switch series all downstream SFP+ ports can be switched to FCoE port. As the FC SAN and Ethernet network are fully integrated, the entire network infrastructure is greatly simplified.
H3C S6805 switch series supports DCB (Data Center Bridging), ISSU (In-service Software Upgrade), OAM (Operations, Administration and Maintenance) and Energy-Efficient Ethernet (EEE). It fully meets the high performance data center requirements, and is easy to manage with green energy consumption.
H3C S6805 switch series supports VXLAN (Virtual Extensible LAN), VXLAN uses a MAC-in-UDP encapsulation method where the original Layer 2 package is added a VXLAN header, and is then placed in a UDP-IP packet. With the help of MAC-in-UDP encapsulation, VXLAN tunnels Layer 2 network over Layer 3 network. This provides two major benefits, higher scalability of Layer 2 segmentation and better utilization of available network paths.
H3C S6805 switch series supports MP-BGP EVPN (Multiprotocol Border Gateway Protocol Ethernet Virtual Private Network) uses standard-based BGP protocol as the control plane for VXLAN overlay networks, providing BGP based VTEP auto peer discovery and end-host reachability information distribution. MP-BGP EVPN delivers many benefits, such as eliminating traffic flooding, reducing full mesh requirements between VTEPs via the introduction of BGP RR, achieving optimal flow based end to end load sharing and more.
H3C S6805 switch series support data center feature, such as Puppet and Chef, which can achieve data center automatic operation and management.
Flexible choice of airflow
To cope with data center cooling aisle design, the H3C S6805 switch series 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.
Excellent manageability
The switch improves system management through the following ways:
Provides multiple management interfaces, including the serial console port, mini USB console port, USB port, two out-of-band management ports, and two SFP ports. The SFP ports can be used as in-band management port through which encapsulated sampling packets are sent to the controller or other management devices for deep analysis.
Supports multiple access methods, including SNMPv1/v2c/v3, Telnet, SSH 2.0, SSL, and FTP.
Supports GRPC that provides flexible programming interfaces for customization.
Supports Telemetry to perform real-time, high-speed, and precise device statistics collection.
Multiple reliability protection
The S6805 switch series provides multiple reliability protection at both switch and link levels. With over current, overvoltage, and ov erheat 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.
The switch supports diverse link redundancy technologies such as H3C proprietary RRPP, VRRPE, and Smart Link. These technologies ensure quick network convergence even when large amount of traffic of multiple services runs on the network.
Rich QoS features
H3C S6805 switch series support Layer 2 to Layer 4 packet filtering, which can provide traffic classification based on source MAC address, destination MAC address, source IP address, destination IP address, TCP/UDP port number, protocol type, and VLAN.
Each 100G port provides a flexible queues scheduling algorithm, which can be set based on ports and queues at the same time.
S6805 switch series supports five queuing modes include SP (Strict Priority), WRR (Weighted Round Robin), SP+WRR, WFQ, and SP+WFQ.
S6805 switch series supports CAR (Committed Access Rate) function with a minimum granularity of 8Kbps, and port mirroring on both directions used to monitor packets on the specified port and forward the packets to the monitoring port for network detection and troubleshooting.
Comprehensive security control policies
H3C S6805 switch series 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 S6805 switch series supports enhanced ACL control logic, which enables an enormous amount of in-port and out-port ACL, and delegate VLAN based ACL. This simplifies user deployment process and avoids ACL resource wastage. S6805 switch series can also take advantage of Unicast Reverse Path Forwarding (Unicast RFP). 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 can effectively prevent the source address spoofing in the network
