3. Rich data center features

* H3C S6820 series switches support rich data center features, support edge virtual bridge EVB (Edge Virtual Bridging), through VEPA (Virtual Ethernet Port Aggregator) mode to upload the data traffic generated by the virtual machine VM (Virtual Machine) to connect to the server Physical switch for processing. Support FCoE technology to realize the carrying of FC messages in Ethernet, so that FC SAN network and Ethernet LAN network can share the same network infrastructure. Support PFC, ETS, DCBX and other data centers without packet loss characteristics to meet the low latency and no packet loss requirements of FC storage services and high-performance computing services.

* H3C S6820 supports the VxLAN protocol, which can build a flexible and easily scalable high-performance two-layer network architecture and support the dynamic migration of server virtual machine cloud data center, as the overlay virtual network VXLAN high-performance hardware gateway to support multi-tenant data center Operating the network and docking with the H3C cloud management platform can build a new generation of data centers that are flexible, efficient, on-demand, with high reliability and high scalability.

4. IRF2 (Second Generation Intelligent Resilient Architecture)

* Facing the application requirements of a unified switching architecture in data centers, the S6820 series switches support IRF2 (second-generation intelligent flexible architecture) technology, which virtualizes multiple devices into one logical device, achieving scalability, reliability, overall architecture and availability It has strong advantages in four aspects:

* Scalability: IRF2 technology allows the switch to use interconnect cables to achieve the expansion of multiple devices; it has the advantages of plug and play, single IP management, and simultaneous upgrades, while greatly reducing the cost of system expansion.

* Reliability: Through the patented routing hot backup technology, the redundant backup of all information on the control plane and the data plane and uninterrupted three-layer forwarding are realized in the entire IRF2 group, which greatly enhances the reliability and high performance of the IRF2 group , At the same time, it eliminates a single point of failure and avoids business interruption.

* Distribution: Through distributed link aggregation technology, load sharing and mutual backup of multiple uplinks are realized, thereby improving the redundancy of the entire network architecture and the utilization of link resources.

* Availability: through the standard 100G/40G Ethernet interface to achieve an intelligent flexible architecture, can allocate business bandwidth and system connection bandwidth according to demand, and rationally allocate local traffic and upstream traffic; not only can achieve intra-rack, cross-rack, and even cross-regional The long-distance intelligent and flexible architecture.

5. Multiple reliability protection

* S6820 series switches have multiple reliability protections at the device level and link level. Using over-current protection, over-voltage protection and over-heat protection technology, all models support pluggable redundant power modules, AC or DC power modules can be flexibly configured according to the needs of the actual environment, in addition to the whole machine also supports power supply and fan Fault detection and alarm, support automatic fan unplug protection function, avoid chip damage, can automatically adjust the fan speed according to temperature changes, these designs make the device have high reliability.

* In addition to equipment-level reliability, this series also supports a wealth of link-level reliability technologies, such as Xin H3C’s original RRPP fast ring network protection mechanism, as well as VRRPE and Smart link. When the network is carrying multiple services and large traffic, it does not affect the convergence time of the network, ensuring the normal development of services.

6. Rich QoS strategy

* H3C S6820 series switches support L2 (Layer 2) ~ L4 (Layer 4) packet filtering functions, providing information based on source MAC address, destination MAC address, source IP address, destination IP address, TCP/UDP port number, protocol type, and VLAN Stream classification. Each 100G port supports multiple unicast and multicast queues, provides flexible queue scheduling algorithms, can be set based on ports and queues at the same time, supports SP (Strict Priority), WRR (Weighted Round Robin), SP+WRR, WFQ , SP+WFQ five modes. Support CAR (Committed Access Rate) function with a minimum granularity of 8Kbps. Supports port mirroring in both outbound and inbound directions, used to monitor the packets on the designated port, and copy the data packets on the port to the monitoring port for network detection and troubleshooting.

* The H3C S6820 switching chip adopts a special XPE buffer architecture. The ingress port and egress port jointly determine the buffer for message storage, avoiding the situation that a single 100G port runs out of buffer under special circumstances, and the efficiency of buffer usage is more fair and reasonable.

7. Excellent management ability

* H3C S6820 series switches support a wealth of management interfaces, such as Console, Mini USB port, USB port, two optical out-of-band management ports, and two in-band optical ports, which can be used as ordinary ports and at the same time The internal data management port encapsulates the sampled message and sends it to the Controller or other management equipment for in-depth analysis.

* Support SNMPv1/v2/v3 (Simple Network Management Protocol), which can support the industry's general network management platform and iMC intelligent management center. Support CLI command line, TELNET, FTP, and support SSH2.0, SSL and other encryption methods, making management more secure.

* H3C S6820 series switches support the sFlow function, SPAN/RSPAN/ERSPAN mirroring and multiple mirrored observation ports. The network traffic can be analyzed to take corresponding management and maintenance measures, so that the originally invisible network business application traffic becomes clear at a glance. Provide users with a variety of network flow analysis reports to help users optimize network structure and adjust resource deployment in a timely manner.

8. Flexible air duct direction selection

* In order to better match the air duct design of the data center, H3C S6820 series switches provide users with more flexible air duct solutions. While realizing the front and rear air ducts, users can also choose different fan frames to achieve different wind directions. (Wind from the power supply side or from the port side).

9. Perfect security control strategy

* H3C S6820 series switches support AAA, RADIUS authentication, support dynamic or static binding of user identification elements such as user accounts, IP, MAC, VLAN, ports, etc.; support real-time management of online users with H3C's iMC platform, and timely Diagnose and dissolve illegal activities on the Internet.

* H3C S6820 series switches provide enhanced ACL control logic, support large-capacity in-port and out-port ACL, and support VLAN-based ACL issuance, which simplifies the user configuration process while avoiding the waste of ACL resources. In addition, the S6820 series switches will also support unicast reverse path finding technology (uRPF). The principle is that when a data packet is received on an interface of the device, it will reversely search the path to verify whether there is a packet from the receiving interface. The routing between the specified source addresses verifies its authenticity, and deletes the data packet if it does not exist, so that we can effectively prevent the increasingly widespread source address spoofing in the network.
