The H3C S7300X-G switch is an Ethernet switch product independently developed by H3C Technologies Co., Ltd. (hereinafter referred to as H3C). It is designed for network environments that require high performance, high port density, high speed, and easy installation and expansion.

The H3C S7300X-G series Ethernet switches offer 10/100/1000Base-T auto-sensing Ethernet ports, SFP, SFP+, QSFP+, and QSFP28 optical ports. They can be widely used in various network environments, including core and aggregation networks in campus networks, providing users with a variety of industry solutions such as IPv4 and IPv6 dual-stack networking and wired/wireless integration.

1Distributed multi-engine design

It adopts an innovative hardware design, providing the system with powerful control capabilities and millisecond-level high reliability through a fully distributed independent control engine, detection engine, and maintenance engine:

* The distributed control engine provides a powerful control processing system for all business boards, easily handling various protocol messages and control messages, and supporting fine-grained control of protocol messages, providing the system with comprehensive resistance to protocol message attacks.

* A distributed detection engine allows all business boards to perform detection in a distributed manner.BFD、OAMIt enables rapid fault detection and integrates with control plane protocols, supporting rapid protection switching and rapid convergence. It can achieve millisecond-level fault detection, ensuring uninterrupted service.

* Distributed maintenance engine, intelligentCPUThe system supports intelligent power management, enabling online status checks of devices and sequential power-on/off of individual boards (reducing power surges caused by simultaneous power-on of individual boards, improving device lifespan, and reducing electromagnetic radiation and system power consumption).

2、IRF2(Second-generation intelligent elastic architecture)

H3C S7300X-GSeries switches supportIRF2(Second-generation intelligent elastic architecture) technology will2The physical devices are interconnected, making them virtual as a single logical device. In other words, users can manage and use these multiple devices as a single device.IRFIt can bring the following benefits to users:

* Simplify managementIRFOnce the architecture is established, it can connect to any port of any device to log in to a unified logical device. By configuring a single device, it can manage the entire intelligent elastic system and all member devices within the system, without having to physically connect to each member device to configure and manage them separately.

* Simplify businessIRFThe various control protocols running in the formed logical devices are also run as a single device. For example, the routing protocol is calculated as a single device. With the application of cross-device link aggregation technology, it can replace the original spanning tree protocol. This can save a lot of protocol message interaction between devices, simplify network operation, and shorten the convergence time when the network is unstable.

* Elastic scaling allows for flexible expansion based on user needs, ensuring the protection of user investment. Furthermore, new devices can be added or removed.IRFThe architecture allows for "hot-swapping" without affecting the normal operation of other devices.

* High reliabilityIRFThe high reliability is reflected in three aspects: the link, the equipment, and the protocol. The physical ports of member devices support aggregation.IRFThe physical connections between the system and upper and lower layer devices also support aggregation, which improves the reliability of the links through multi-link backup;IRFThe system consists of multiple member devices, onceMasterIn case of equipment failure, the system will quickly and automatically elect a new one.MasterThis ensures uninterrupted service through the system, thereby achieving device-level [unclear - possibly related to security/safety].1：NBackup;IRFThe system has a real-time protocol hot backup function responsible for backing up the protocol configuration information to all other member devices, thereby achieving...1：NThe reliability of the protocol.

* For high-end switches, performance and port density improvements are limited by hardware architecture.IRFThe system's performance and port density areIRFThe sum of the performance and number of ports of all internal devices. Therefore,IRFTechnology can easily increase the switching capacity and user port density of a device several times over, thereby significantly improving the device's performance.
