H3C S9820 high-density intelligent switch series is developed for data centers and high-end campus networks. It provides powerful hardware forwarding capacity and abundant data center features. It provides up to 64*100G QSFP28 ports and 2 out-of-band management ports (one fiber port and one copper port). The 100G QSFP28 ports are 100G/40G autosensing and each QSFP28 ports can be split into four interfaces. This enables the switch to provide up to 128*25G/10G ports. The switch supports modular power modules and fan trays. By using different fan trays, the switch can provide field-changeable airflows.
The switch is an ideal product for high-density 100GE or 40G switching and aggregation at data centers and cloud computing networks. It can also operate as a TOR access switch on an overlay or integrated network.
The S9820 switch series has one model:
S9820-64H. The switch provides 64 × 100G QSFP28 ports, 2 × out-of-band management ports, 1 × mini USB port, 1 × USB port, 3 × fan tray slots, and 4 × power module slots. The switch uses 650W AC or DC removable power modules and supports 2+2 power module redundancy.

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 Distributed Resilient Network Interconnection (DRNI)

H3C S9820 switch series 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.

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

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.
