H3C S9825 series switches are a new generation of high-performance, high-density 400GE Ethernet switches launched by H3C for data centers. Provides high-density 400GE ports; supports redundant pluggable power supplies and fans. The S9825 can be used in the core and aggregation networking of the new generation data center.
The S9825 switch series includes one model:

The switch offers high-density 400G ports and a forwarding capacity as high as 51.2Tbps, which enables the switch to provide high-density server access in high-end data centers without oversubscriptions.
The switch supports abundant data center features, including:
H3C S9825 series switches supports MP-BGP EVPN (Multiprotocol Border Gateway Protocol Ethernet Virtual Private Network) which can run as VXLAN control plane to simplify VXLAN configuration, eliminate traffic flooding and reduce full mesh requirements between VTEPs via the introduction of BGP RR.
H3C S9825 series switches support ROCEv2 network, based on Priority-based Flow Control (PFC), ECN Enhanced Transmission Selection (ETS). Which ensures low latency and lossless RDMA applications and high-speed computing services.
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 S9825 switch series conform to the trend of automated data operation and maintenance, and support visualization of data center. H3C S9825 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, 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.
H3C S9825 series switches adopt the next-generation chip with more flexible Openflow flow Table, 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 S9825 series switches can interconnect with H3C SeerEngine-DC Controller for SeerFabric solutions.
H3C S9825 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.
S9825 switch series supports five queuing modes include SP (Strict Priority), WRR (Weighted Round Robin), SP+WRR, WFQ, and SP+WFQ.
S9825 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 switch improves system management through the following ways:
Provides multiple management interfaces, including the serial console port, USB port, one 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.
