H3C S6850 Series Data Center Switches
H3C S6850 high-density intelligent switch series is developed for data centers and cloud computing networks. It provides powerful hardware forwarding capacity and abundant data center features, offering up to 48*25G ports and 8*100G ports. The switch supports redundant and hot-swappable power supplies and fans, with field-changeable airflow configurations.
This switch series is ideal for high-density 25GE switching and aggregation in data centers and cloud computing networks, and can operate as a TOR access switch on overlay or integrated networks.
Available Models
S6850-56HF: 48 * 25G SFP28 ports, 8 * 100G QSFP28 ports (25GE SFP28 supports autosensing down to 10GE/1GE)
S6850-2C: 2 service slots, 2 * 100G QSFP28 ports
Data Center Features
- VXLAN: Provides higher scalability of Layer 2 segmentation and better network path utilization
- MP-BGP EVPN: Serves as VXLAN control plane to simplify configuration and reduce full mesh requirements
- FCoE (Fiber Channel over Ethernet): Enables storage, data, and computing services transmission on one network
- Data Center Bridging: PFC, ETS, and DCBX ensure low latency and zero packet loss for storage and computing services

High-Density 25GE Access
The switch offers high-density 100G/40G/25G/10G ports with wire-speed forwarding capacity up to 4 Tbps. With standard 25G ports, it provides high-density server access for high-end data centers.
RoCE (RDMA over Converged Ethernet)
Remote Direct Memory Access (RDMA) directly transmits user application data to server storage spaces, eliminating multiple data copying and context switching operations to reduce CPU load.
RoCE Key Features: PFC (Priority-based Flow Control), ECN (Explicit Congestion Notification), DCBX (Data Center Bridging Capability Exchange Protocol), ETS (Enhanced Transmission Selection)
