range functions for centers processing data
The switches support a wide range of data center features, including the following:
Virtual bridging edge device connection (EVB) – supports offloading virtual machine data traffic to physical switches connected to servers for data processing, using Virtual Ethernet Port Aggregation (VEPA) mode.
Fibre Channel over Ethernet (FCoE) – allows FC packets to be sent over an Ethernet network, allowing services to FC SANs and LAN services can share the same network infrastructure.
Priority Flow Control (PFC), advanced transport selection ( ETS) for bandwidth management and DCBX (Device Interconnected Configuration) to help support FC storage and high-performance computing with low latency and no data loss.
Virtual Extensible Local Area Networks (VXLAN) – The switch can act as a high-performance VXLAN hardware gateway to support data center services for multiple tenants. When used in conjunction with the H3C cloud management platform, the switch can provide a flexible, resilient, highly available, high-performance Layer 2 network that supports long-distance virtual machine and data migration and business continuity.
Technology intelligent fault-tolerant architectureH3C IRF2
H3C IRF2 intelligent fault-tolerant architecture technology allows you to virtualize multiple switches into one virtual switch, which provides the following benefits:
Excellent scalability: using IRF2 Device aggregation can be done in a plug-and-play manner by simply adding one or more switches to an IRF2 stack and enabling IRF2 stacking mode on the new device. New devices can be managed through a single shared IP address, allowing software updates to be carried out simultaneously on all devices to reduce network expansion costs.
High reliability: patented IRF2’s 1:N redundancy technology allows each of the slaves in the IRF2 stack to serve as a backup for the master, providing control plane redundancy and data link redundancy, as well as uninterrupted Layer 3 forwarding. This improves reliability and helps avoid interruptions at work and generally improve productivity. If the main device fails, traffic transmission does not stop.
Load balancing: IRF2 supports link aggregation across devices, allowing connections to higher and lower level devices using multiple physical links. This creates another layer of redundancy in the network and promotes fuller utilization of network resources.
Availability: IRF2 technology is implemented in H3C’s S9820 series switches via standard 100 ports Gigabit Ethernet (100GE) or 40 Gigabit Ethernet (40GE). It allows you to allocate bandwidth for both service and application traffic, providing the necessary separation between local traffic and traffic to upstream systems. IRF2 rules can be applied not only at the scale of one rack or adjacent racks, but also at the scale of the entire local network.
Various means increasing reliability
< p style="font-weight: 400;">The S9820 series switches implement various protection schemes to improve reliability at both the switch and link levels. All models, equipped with overcurrent, overvoltage and overtemperature protection, support redundant, removable power supplies, giving you the flexibility to select AC or DC power supplies based on your actual needs. All switches in the line support fault detection and alarm transmission for power supplies and fan modules, as well as adjusting fan speed based on ambient temperature.
The switches support a variety of channel reservation technologies, such as proprietary H3C developments – RRPP, VRRPE and Smart Link. These technologies ensure rapid network convergence, even in cases where the network carries large volumes of traffic from many different services.
Comprehensive < b>functions management quality service(QoS)
The switches provide a wide range Quality of Service management features, including:
H3C’s S9820 Series switches support Layer 2 through Layer 4 packet filtering, allowing for MAC-based traffic classification – source addresses, Destination MAC address, source IP address, destination IP address, TCP/UDP port number, protocol type and VLAN.
On each port 100G provides flexible queuing algorithms that can be applied simultaneously at both the port and queue levels.
The S9820 series switches support five queuing methods, including Strict Priority (SP), Weighted Round Robin (WRR), SP+WRR, Weighted Fair Queuing (WFQ), and SP+WFQ.
S9820 series switches support Committed Access Rate (CAR) functionality with a minimum configuration step of 8 kbps, as well as port mirroring in both directions, which is used to monitor traffic on specific port and forwards packets of the duplicate port to the monitoring port to detect and resolve network faults.
The special XPE buffering structure in the switching chips allows the system to balance packets on incoming and outgoing ports. This avoids buffer overload on a single port and improves buffer utilization.
Extensive capabilities control
Multiple management interfaces, including console port, mini-USB port , USB port and two ports for out-of-band management.
Supports configuration and management via command line interface (CLI) or popular network management platforms, as well as using H3C IMC Intelligent Management Center network management systems.
Supports various access methods, including SNMPv1/v2c/v3, Telnet, SSH 2.0, SSL and FTP.< /p>
Support for standard NETCONF APIs that enable users to configure and manage switches, enhancing compatibility with third-party applications.
< p style="font-weight: 400;">It provides a range of traffic monitoring features and analytics tools, including sFlow, NetStream, SPAN/RSPAN/ERSPAN mirroring and port mirroring, so users can accurately analyze traffic and obtain information about application traffic on the network. Using these tools, clients can collect network traffic data to assess network health, receive traffic analysis reports, plan traffic management parameters and optimize resource allocation.
This technology supports real-time monitoring of port buffers and queues, which allows you to obtain accurate information and perform dynamic optimization network.
Switches support PTP (Precision Time Protocol), which ensures highly accurate clock synchronization on devices.

The choice of air flow direction (from the front to the rear or vice versa) can be done by users by installing the appropriate models of fan modules.
Comprehensive < b>policy security security
H3C S9820 series switches support Authentication, Authorization and Accounting (AAA), RADIUS Authentication, User Account Authentication, IP Address User Authentication, MAC Address User Authentication, VLAN and port networks, as well as dynamic and static binding; When paired with the H3C IMC network management platform, they provide real-time management, instant diagnostics, and mitigation of unacceptable network behavior.
S9820 Series switches from H3C support advanced management capabilities based on access control lists (ACL); You can define a large number of ACLs for each incoming and outgoing port, and you can also use ACLs in conjunction with a VLAN. This simplifies user registration and avoids wasting ACL resources.
In addition, the S9820 series switches take full advantage of reverse forwarding technology for unicast traffic ( Unicast Reverse Path Forwarding (uRPF). When a device receives a packet, it checks the return route to confirm the source address where the packet supposedly came from, and discards the packet if there is no such path.
This technology supports monitoring of buffers and port queues in real time, which allows you to obtain accurate information and dynamically optimize the network.
