The switches support a wide range of data center features, including:
Fiber Channel over Ethernet (FCoE) – Allows FC packets to be carried over an Ethernet network so that FC SAN services and LAN services can share the same network infrastructure.
Priority-Based Flow Control (PFC), Explicit Congestion Notification (ECN), and DCBX—help support FC storage and high-performance computing with low latency and no data loss.< /p>
Virtual Extensible Local Area Networks (VXLAN) – The switch can act as a high-performance VXLAN hardware gateway to support data center services for a large number of (16 million) users -tenants. When used in conjunction with the H3C cloud management platform, the switch can provide the basis for flexible, resilient, highly available, high-performance Layer 2 network supporting long-distance migration of virtual machines and data, as well as business continuity.
Data Center Bridging (DCB) features ), RDMA over Converged Ethernet (RoCE), Non-Disruptive Software Update (ISSU) and Operations, Administration and Maintenance (OAM) support high performance services.
Puppet and Chef modes – help automate the operation and maintenance of data centers.
Flexible choice directions airflow
To adapt to the cooling flow patterns of data center aisles, H3C’s S9850 Series switches offer flexibility in airflow direction, which can be either front-to-back or reverse. . The choice of airflow direction (from front to rear or vice versa) can be done by users by installing appropriate models of fan modules.
Wide < b>capabilities management
In switches The following features are implemented to enhance system management:
Multiple management interfaces, including a serial console port, a mini-USB console port, a USB port, two out-of-band management ports, and two SFP ports. SFP ports can be used as service ports or in-band management ports through which encapsulated probe packets are routed to the controller or other management devices for in-depth analysis.
Customization support and management via the command line interface (CLI) or popular network management platforms, as well as using the H3C IMC Intelligent Management Center network management system.
Supports various methods access, including SNMPv1/v2c/v3, Telnet, SSH 2.0, SSL and FTP.
Supports GRPC, which provides flexible programming interfaces for customization.

Technology intelligent fault-tolerant architecture H3C IRF2
The S9850 series switches from H3C implement Intelligent Resilient Framework 2 (IRF2) technology. IRF2 provides the following benefits:
Excellent scalability: With IRF2, device aggregation can be plug-and-play by simply adding one or more switches to the stack IRF2 and enabling IRF2 stacking mode on the new device. New devices can be managed through a single shared IP address, allowing software updates to be carried out simultaneously on all devices to reduce network expansion costs.
High reliability: patented IRF2’s 1:N redundancy technology allows each of the slaves in the IRF2 stack to serve as a backup to the master, providing control plane redundancy, data link redundancy, and uninterrupted Layer 3 forwarding. This improves reliability and helps avoid interruptions at work and generally improve productivity. If the primary device fails, traffic does not stop.
Load balancing: IRF2 supports link aggregation across devices, allowing connections to higher and higher-level devices low level using multiple physical channels. This creates another layer of redundancy in the network and promotes fuller utilization of network resources.
Availability: IRF2 technology is implemented by H3C over standard 100 Gigabit Ethernet (100GE) ports or 40 Gigabit Ethernet (40GE). It allows you to allocate bandwidth for both service and application traffic, providing the necessary separation between local traffic and traffic to upstream systems. IRF2 rules can be applied not only at the scale of one rack or adjacent racks, but also at the scale of the entire local network.
Various means increasing reliability
< p style="font-weight: 400;">The S9850 series switches implement various protection schemes to improve reliability at both the switch and link levels. All models, Equipped with overcurrent, overvoltage and overheating protection, they support redundant, removable power supplies, allowing you to flexibly select AC or DC power supplies depending on your actual needs. All switches in the line support fault detection and alarm transmission for power supplies and fan modules, as well as adjusting fan speed based on ambient temperature.
The switches support a variety of channel reservation technologies, such as proprietary H3C developments – RRPP, VRRPE and Smart Link. These technologies ensure rapid network convergence even when the network carries large volumes of traffic from many different services.
Wide < b>selection functions controls quality service (QoS)
H3C S9850 Series switches support Layer 2 to Layer 4 packet filtering, which allows traffic classification based on source MAC address, destination MAC address, source IP address, IP address destination, TCP/UDP port number, protocol type and VLAN.
Each of the 100G ports provides flexible queue scheduling algorithms that can be used simultaneously on both port level and at the queue level.
S9850 series switches support five queuing methods, including Strict Priority (SP), Weighted Round Robin service (Weighted Round Robin, WRR), SP+WRR, weighted fair queuing (WFQ) and SP+WFQ.
Series switches The S9850 supports Committed Access Rate (CAR) functionality with a minimum tuning step of 8 kbps, as well as port mirroring in both directions, which is used to monitor traffic on a specific port and forward packets of the duplicated port to the monitoring port for detection and troubleshooting network problems.
Comprehensive policies < strong>ensuring security
H3C S9850 Series switches support authentication, authorization and accounting (AAA), RADIUS authentication, user account authentication, IP address, MAC address, VLAN and port user authentication, and dynamic and static binding; when paired with the H3C IMC network management platform, they provide real-time management, instant diagnostics, and suppression of unacceptable network behavior.
H3C’s S9850 Series switches support advanced ACL-based management capabilities, allowing multiple ACLs to be defined for each ingress and egress port, as well as VLAN-based ACLs to simplify user registration and enable Avoid wasting ACL resources Additionally, the S9850 series switches take full advantage of Unicast Reverse Path Forwarding (uRPF) technology. When a device receives a packet, it checks the return route to confirm the source address where the packet supposedly came from, and discards the packet if there is no such path.
