The H3C S9825 switch adopts the industry's mainstream programmable switching chip, which can flexibly define forwarding logic according to user needs, develop new features that meet user network evolution trends, and provide users with the new features they need through simple software upgrades, thus providing unlimited possibilities for user network expansion and timely evolution.
Rich data center features
H3C S9825 switch fully supports data center lossless network RoCEv2 features, supporting PFC、ETS、DCBX、ECN、Fast ECN、BUFFER Visualize and optimize parameters to ensure zero packet loss and low latency network capability delivery. And it supports typical box+box RoCE networks with 400G lossless Fabric, while meeting the needs of ultra large scale networking and low latency in data centers. A network architecture that supports direct connection topology, selects short and non congested message forwarding paths through active perception of link congestion status, achieves the effect of improving network throughput and resilience, reducing network latency, and has the ability to build large-scale supercomputer cluster networking. S9825 supports multi-path ECMP load balancing, flow by flow load balancing Flowset (Flowlet), microflow order preservation, and Spraylink packet by packet (AR) load balancing for multi-path ECMP forwarding.
Powerful visualization capabilities
With the rapid development of data center technology, the scale of data centers is rapidly expanding, and the reliability and operability of data centers have become bottlenecks that restrict further expansion of data centers. The H3C S9825 series switches conform to the development trend of automated operation and maintenance in data centers, supporting visualization functions. Through protocols such as ERSPAN, gRPC, Telemetry, etc., real-time resource information of switches, including switch basic information, RoCE related cache real-time status, RDMA statistical information such as ECN and PFC key events, RDMA alarm information, interface QoS queue and interface utilization real-time status, optical module Media Side SNR, etc., can be uploaded to the data center operation and maintenance platform. The operation and maintenance platform analyzes these real-time data, which can achieve network quality traceability, fault investigation, risk warning, architecture optimization and even automatically adjust network configuration to reduce network congestion, making it possible for data center operation and maintenance to move towards automation.
Multiple reliability protection
The S9825-128B host supports a flexible main control design, with a pluggable main control module to improve its maintainability, and supports smooth upgrades to higher performance main controls.
The S9825 switch has multiple reliability protections at the device level and link level. Adopting overcurrent protection, overvoltage protection, and overheating protection technologies, supporting pluggable redundant power modules, the device can flexibly configure AC or DC power modules according to actual environmental needs. In addition, the whole machine also supports fault detection and alarm of power and fan, supports automatic protection function for unplugged fan to avoid chip damage, and can automatically adjust the fan speed according to temperature changes. These designs make the device highly reliable.
Rich QoS strategies
The H3C S9825 switch supports L2 (Layer 2) to L4 (Layer 4) packet filtering function, providing flow 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 supports multiple unicast and queue scheduling algorithms, providing flexible queue scheduling algorithms that can be set based on both ports and queues. It supports five modes: SP (Strict Priority), WRR (Weighted Round Robin), SP+WRR, WFQ, and SP+WFQ. Support CAR (Committed Access Rate) function, with a minimum granularity of 8Kbps. Support port mirroring in both outbound and inbound directions, used to monitor messages on specified ports, copy data packets on ports to monitoring ports for network detection and troubleshooting.
