This series of models supports up to 32 400GE ports, with extremely high port density and powerful forwarding capabilities, which can meet the networking needs of high-density servers in super large data centers without convergence access.
Enhanced SDN capabilities
The H3C S9855 switch industry adopts mainstream programmable switching chips, 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 S9855 switch supports lossless network in data center intelligent computing scenarios, fully supporting RoCE features including PFC, ECN, AI ECN, IPCC, iNOF, Agile Buffer, etc., to build a zero packet loss and low latency intelligent computing network. The product supports 100GE/200GE/400GE lossless Fabric typical box+box or box+box RoCE networks, meeting the needs of ultra large scale networking in data centers. A network architecture that supports direct connection topology, actively perceives link congestion status to select short and congestion free message forwarding paths, achieves the effect of improving network throughput and resilience, reducing network latency, and has the ability to build large-scale supercomputing cluster networks.
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 S9855 series switches conform to the development trend of automated operation and maintenance in data centers, supporting visualization functions. Through protocols such as ERSPAN and gRPC, real-time resource information, RDMA statistics, and RDMA alarm information of the switches can be uploaded to the data center operation and maintenance platform. The operation and maintenance platform analyzes these real-time data and can achieve functions such as network quality traceability, fault diagnosis, risk warning, architecture optimization, etc. It can even automatically adjust network configuration, reduce network congestion, and make it possible for data center operation and maintenance to move towards automation
Multiple reliability protection
The S9855 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 S9855 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 port supports multiple unicast queues, providing flexible queue scheduling algorithms that can be set based on both the port and queue. 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.
Excellent management skills
• Supports a variety of management interfaces, such as Console, USB ports, and out of band management ports.
• Supports SNMP v1/v2/v3 (Simple Network Management Protocol), which can support industry standard network management platforms and iMC intelligent management centers. Support CLI command line, TELNET、FTP， And it supports encryption methods such as SSH 2.0 and SSL, making management more secure.
Supports the standard Netconf interface, providing a programmable method for configuring and managing network devices. It makes it very convenient for the development of third-party software, meeting users' needs for openness and flexibility in devices.
Supports sFlow and Netspeak functions, allowing for fine-grained statistics of messages. Supports SPAN/RSPAN/ERSPAN/ERSPANV3 mirrors and multiple mirror observation ports, allowing for analysis of network traffic to take corresponding management and maintenance measures, making previously invisible network business application traffic clear at a glance. Multiple network flow analysis reports can be provided to users to help optimize network structure and adjust resource deployment in a timely manner.
• Support real-time monitoring of Buffer and port queues, providing the possibility for dynamic adjustment of network operation and maintenance visualization.
A comprehensive security control strategy
The H3C S9855 switch supports AAA, Radius authentication, and supports user accounts IP、MAC、VLAN、 Dynamic or static binding of user identification elements such as ports; Support real-time management of online users in collaboration with H3C's iMC platform, enabling timely diagnosis and dismantling of illegal online activities.
The H3C S9855 switch provides enhanced ACL control logic, supports large capacity inbound and outbound port ACLs, and supports VLAN based ACL issuance, simplifying the user configuration process while avoiding wastage of ACL resources.
