Technology intelligent fault-tolerant architectureIRF2
In series switches The S6800 from H3C implements 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 for the master, providing control plane redundancy and data link redundancy, as well as 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 aggregation of connections across multiple devices. Connections to upstream and downstream systems can be made through multiple physical links, creating another layer of redundancy and increasing network resource utilization.
Availability: IRF2 technology implemented H3C uses standard 40 Gigabit Ethernet (40GE) or 10 Gigabit Ethernet (10GE) ports and provides bandwidth allocation for service traffic and application access, with intelligent separation of local traffic from 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.
Wide range functions for centers processing data
The switches support a wide range of data center features, including the following:
Edge Virtual Bridging (EVB) – The switch provides traffic forwarding between virtual machines (VMs) and solves the problems of delineating connections and managing between virtual machines and the network using the virtual Ethernet port aggregation (VEPA) mode.
Transparent connection multi-channel (TRILL) – helps create large, fault-tolerant, high-performance Layer 2 networks with support for moving virtual machines and data over long distances.
Virtual extensible LANs (VXLAN) – The switch can act as a high-performance hardware VXLAN gateway to support data center services for multiple tenants. When used in conjunction with the H3C cloud management platform, the switch can form the basis for a flexible, resilient, highly available and high-performance Layer 2 network with support for moving virtual machines and data over long distances, as well as ensuring business continuity.
Fiber Channel over Ethernet (FCoE) – allows you to transmit FC packets over an Ethernet network, so that FC SAN services and LAN services can share the same network infrastructure.
Priority-based flow control (PFC), Extended Transport Selection (ETS) for lane control and Automatic Detection of Connected Devices (DCBX) – help support FC storage and high-performance computing with low latency and no data loss.
< b>Flexible choice directions airflow
To adapt to the cooling flow patterns in data center aisles, H3C’s S6800 Series switches offer flexibility in terms of selection of the blowing direction, which can be carried out both in the direction from the front panel to the rear, and in the opposite direction. 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 possibilities control quality service (QoS)< /b>
The switches provide a wide range of quality of service management features, including the following:
Packet filtering based on layer 2 to 4 packet headers.
Traffic classification based on source MAC address, destination MAC address, IP -source address, destination IP address, TCP/UDP port number, protocol type and VLAN.
High availability
The switches feature removable power supplies, with the ability to select AC or DC power supplies depending on the needs. Power supplies offered for switches include self-protection mechanisms that are triggered when overcurrent, overvoltage, or overtemperature are detected. The switch is capable of detecting faults in power supplies and fan modules and issuing an alarm when faults are detected.
The switches support a variety of channel redundancy 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>capabilities management
In switches The following features are implemented to enhance system management:
Multiple management interfaces, including a console port, a mini-USB port, a USB port, and two out-of-band management ports.< /p>
Supports configuration 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 access methods, including SNMPv1/v2c/v3, Telnet, SSH 2.0, SSL and FTP.
Support for standard NETCONF APIs, through which users can configure and manage switches, extends compatibility with third-party applications.
It provides a range of traffic monitoring functions and analytics tools, including sFlow , NetStream, SPAN/RSPAN/ERSPAN mirroring, and port mirroring to enable users to perform accurate traffic analysis and gain insight into application traffic on the network. With these tools, customers can collect network traffic data to assess network health, receive traffic analysis reports, plan traffic management settings, and optimize resource provisioning.
Comprehensive policy security security< /b>
The switches support authentication, authorization and accounting (AAA) functions, including authentication via RADIUS, as well as dynamic and static binding of user identification elements such as such as user account, IP address, MAC address, VLAN ID and port number. When you use a switch with the H3C IMC management system, you can manage and monitor active users in real time and take immediate action if violations are detected.
The switches offer the ability to assign a large number of access control lists for incoming and outgoing traffic, as well as access control lists based on VLAN. This simplifies customization and saves ACL resources.
