            High port density and powerful forwarding capacity

            The switch offers high-density 100G/40G/25G/10G ports and a forwarding capacity as high as 12.8 Tbps. By splitting one port into four ports, it can provide a maximum of 128 25G/10G ports. This enables the switch to provide high-density server access in high-end data centers without oversubscriptions.

            Powerful SDN capacity

            The new-generation switching chip architecture greatly enhances the SDN capacity of the switch. IFP handles OpenFlow flow tables with more flexibility and resources. The switch supports exact match for ACLs to handle massive traffic on data center SDN networks.

            Supporting the standard OpenFlow protocol, the switch can be managed by an H3C VCF controller, a mainstream cloud management platform, or a third-party controller, which can provide flexible network customization and automated network management. Users or third-parties can use standard interfaces to develop and deploy dedicated network management polices to enable rapid service deployment and expansion and intelligent device management.

            Abundant data center features

            The switch supports abundant data center features, including:

            * EVB—Supports using Virtual Ethernet Port Aggregator (VEPA) to upload data traffic of VMs to physical switches connected to the server for processing.

            * FCoE—Allows transmission of FC packets over Ethernet so that FC SAN services and LAN services can run over the same network infrastructure.

            * PFC, ETS, and DCBX—Helps provide FC storage and high-performance computing services with low-latency and no data loss.

            * VXLAN—The switch can operate as a high-performance VXLAN hardware gateway to support multitenant data center services. In conjunction with the H3C cloud management platform, the switch can be used to set up an agile, resilient, highly available high-performance Layer 2 network, with support for long-distance virtual machine mobility, data mobility, and business continuity.

            H3C Intelligent Resilient Framework 2 (IRF2)

            H3C Intelligent Resilient Framework 2 (IRF 2) can virtualize multiple switches into one virtual switch and provides the following benefits:

            * High scalability: With IRF2, plug-n-play device aggregation can be achieved by adding one or more switches into the IRF2 stack, enabling IRF2 stacking on the new device. New devices can be managed with a single IP, and upgraded at the same time to reduce network expansion cost.

            * High reliability: The IRF2 patented 1:N backup technology allows each slave device in the IRF2 stack to serve as the backup of the master, creating control and data link redundancy, and uninterrupted layer-3 forwarding. This improves reliability, avoids unplanned business downtime, and serves to improve overall performance. When the master device fails, traffic remains uninterrupted.

            * Load balancing: IRF2 supports cross-device link aggregation, allowing upstream and downstream to be connected to more than one physical link. This creates another layer of network redundancy, and boosts the network resource utilization.

            * Availability: H3C S9820 switch series Implements IRF2 through standard Hundred Gigabit Ethernet (100GE) or 40 Gigabit Ethernet (40GE) ports. It can allocate bandwidth for business and application access, and reasonably splits local traffic and upstream traffic. IRF2 rules are obeyed within and across the rack, but also across the LAN.Multiple reliability protection

            Multiple reliability protection

            * The S9820 switch series provides multiple reliability protection at both switch and link levels. With over current, 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.

            * 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.

            Abundant QoS features

            The switch provides abundant QoS features, including:

            * H3C S9820 switch series supports 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.

            * S9820 switch series supports five queuing modes include SP (Strict Priority), WRR (Weighted Round Robin), SP+WRR, WFQ, and SP+WFQ.

            * S9820 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.

            * The special XPE buffer structure in the switching chips allows the system to balance packets to the inbound or outbound port. This avoids buffer congestion on a single port and improves buffer usage efficiency.

            Outstanding management capacity

            The switch improves system management through the following ways:

            * Provides multiple management interfaces, including the console port, mini USB port, USB port, and two out-of-band management ports.

            * Supports configuration and management from CLI or a mainstream network management platform and H3C IMC Intelligent Management Center.

            * Supports multiple access methods, including SNMPv1/v2c/v3, Telnet, SSH 2.0, SSL, and FTP.

            * Supports standard NETCONF APIs that allow users to configure and manage the switch, enhancing the compatibility with third-party applications.

            * Provides a variety of traffic monitoring and analytic tools, including sFlow, NetStream, SPAN/RSPAN/ERSPAN mirroring, and port mirroring to help customers perform precise traffic analysis and gain visibility into network application traffic. With these tools, customers can collect network traffic data to evaluate network health status, create traffic analysis reports, perform traffic engineering, and optimize resource allocation.

            * Supports realtime monitoring of buffer and port queues, allowing for visible and dynamic network optimization.

            * Supports PTP (Precision Time Protocol) to achieve highly precise clock synchronization.

            Flexible choice of airflows

            * To cope with data center cooling aisle design, the H3C S9850 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.

            Comprehensive security control policies

            * H3C S9820 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 behaviors

            * H3C S9820 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.

            * S9820 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.
