H3C S9855 series switches are a new generation of high-performance, high-density 400GE/100GE Ethernet switches launched by H3C for data centers. Provides high-density 400GE/200GE/100GE ports; supports redundant pluggable power supplies and fans. The S9855 can be used in the core and aggregation networking of the new generation data center. It connects to the S12500 series core switches through 400GE uplinks, and connects to 200GE/100GE servers in the downlink, providing high-bandwidth and large-capacity server access.
The S9855 switch series includes four models:

The switch offers high-density 400G/200G/10G ports and a forwarding capacity as high as 16Tbps, 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 S9855 series switches supports MP-BGP EVPN and VxLAN VTEP.
H3C S9855 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 S9855 switch series conform to the trend of automated data operation and maintenance, and support visualization of data center. H3C S9855 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 S9855 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 S9855 series switches can interconnect with H3C SeerEngine-DC Controller for SeerFabric solutions.
H3C S9855 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.
S9855 switch series supports five queuing modes include SP (Strict Priority), WRR (Weighted Round Robin), SP+WRR, WFQ, and SP+WFQ.
S9855 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, mini USB console port, USB port, two out-of-band management ports, and two SFP ports. The SFP ports can be used as service ports or in-band data management ports, through which the sampled packets are encapsulated and sent to the controller or other management devices for in-depth analysis.
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 GRPC and provides a flexible programmable interface for customized development.
