Rich data center business features
Virtualization cluster switching technology
Support VSS virtualization cluster switching technology, which can virtualize multiple physical devices into a logical device. The performance, reliability, flexibility, and management of its virtual system are unparalleled compared to independent physical devices.
Doubling performance: Virtualization systems can fully utilize every link between physical devices, avoiding the blocking of links by traditional networking model spanning tree protocols, making full use of resources, doubling performance, and maximizing the protection of existing link investments.
High reliability: Based on advanced distributed processing technology and efficient cross physical device link aggregation function, the separation of logical control plane and business data plane is achieved, providing uninterrupted three-layer routing forwarding, avoiding business interruption caused by single point failure, and greatly improving the reliability of virtual systems.
Flexibility: Through the virtual cluster function, the distance of the virtual cluster system can be extended to 80KM, which is flexible and convenient, breaking the geographical limitations of traditional cluster technology.
Easy to manage: The entire virtual system achieves unified management of a single IP address, and the actual physical devices are transparent to users, simplifying the management of network devices and network topology, greatly improving network operation efficiency, and effectively reducing operation and maintenance costs.
Unified Switching: Supports FCoE (FC over Ethernet) technology to solve the problem of heterogeneity between LAN networks and FC storage networks, thereby achieving the integration of computing, data, and storage networks and achieving unified switching.
High reliability at the data center level
Based on the HPS (Hitless Protection System) uninterruptible protection system, the critical power system adopts redundant design, modular and hot swappable, supports seamless switching in case of failure, and does not require business interruption.
Supports STP/RSTP/MSTP protocol, VRRP protocol, as well as simple and efficient redundancy protection mechanisms such as ring network protection, dual uplink primary and backup link protection, LACP link aggregation, etc.
Support ISSU (In Service Software Upgrade) business uninterrupted system upgrade, ensuring uninterrupted forwarding of user data during system upgrade and main control switching.
The ultra-high precision BFD bidirectional link detection mechanism achieves millisecond level fault detection and business recovery through linkage with layer 2 and layer 3 protocols, greatly improving the reliability of the network system.
￭ A comprehensive Ethernet OAM mechanism that supports 802.3ah, 802.1ag, and ITU-Y.1731, enabling rapid detection and localization of faults through real-time monitoring of network operation status.
The high reliability design of software and hardware meets the requirement of 50ms fault recovery time, truly achieving high reliability of 5 core devices (99.999%).
