Support front panel exit, flexible and convenient wiring.
Facing the application requirements of a unified switching architecture in data centers, the S5850 series switches support IRF2 (second-generation intelligent flexible architecture) technology, virtualizing multiple devices into one logical device, in terms of scalability, reliability, overall architecture and availability It has powerful advantages, mainly reflected in four aspects:
Scalability: IRF2 technology allows the switch to use interconnect cables to achieve the expansion of multiple devices; it has the advantages of plug and play, single IP management, and simultaneous upgrades, while greatly reducing the cost of system expansion.
Reliability: Through the patented routing hot backup technology, redundant backup of all information on the control plane and data plane and uninterrupted three-layer forwarding are realized in the entire IRF2 group, which greatly enhances the reliability and high performance of the IRF2 group. At the same time, a single point of failure is eliminated and business interruption is avoided.
Distribution: Through distributed link aggregation technology, the load sharing and mutual backup of multiple uplinks are realized, thereby improving the redundancy of the entire network architecture and the utilization of link resources.
Availability: A smart and flexible architecture is realized through a standard 10 Gigabit Ethernet interface, which can allocate business bandwidth and system connection bandwidth according to needs, and reasonably allocate local traffic and uplink traffic; not only can achieve remote distances within the rack, across racks, and even across regions. Distance smart elastic architecture.
H3C S5850 supports the VXLAN protocol, which can build a flexible and easily scalable high-performance two-layer network architecture and support the dynamic migration of server virtual machine cloud data center, as the overlay virtual network VXLAN high-performance hardware gateway to support multi-tenant data center operations The network, docking with the H3C cloud management platform, can build a new generation of data centers that are flexible, efficient, on-demand, with high reliability and high scalability.
Software Defined Network (SDN) is an innovative network architecture system. Its core technology, Openflow, greatly simplifies the management and maintenance of the network by separating the control layer and the data forwarding layer of the network, and more importantly, it realizes the flexible control of network traffic, which provides a good solution for the innovation of core networks and applications. Network platform. The S5850 can cooperate with multiple Openflow controllers to implement SDN solutions.
In order to better match the air duct design of the data center, H3C S5850 series switches provide users with more flexible air duct solutions. While realizing the front and rear air ducts, users can also choose different fan frames to achieve different wind directions ( From front to back or from back to front).
The H3C S5850 switch supports L2(Layer 2)~L4(Layer 4) packet filtering function, and provides based on source MAC address, destination MAC address, source IP address, destination
IP address, TCPPUDP port number, protocol type, VLAN flow classification.
H3C S5850 series switches have multiple reliability protections at the device level and link level. It adopts over-current protection, over-voltage protection and over-heat protection technologies, and supports pluggable redundant power modules, which means that AC or DC power modules can be flexibly configured according to the needs of the actual environment. In addition, the whole machine also supports power supply and fan failures Detection and warning can automatically adjust the speed of the fan according to temperature changes. These designs make the equipment have high reliability.
In addition to equipment-level reliability, S5850 also supports a wealth of link-level reliability technologies, such as VRRPE. When the network is carrying multiple services and large traffic, it does not affect the convergence time of the network and ensures the normal development of services.
H3C S5850 series switches support rich management interfaces, such as Console port, Mini USB port, USB port and two out-of-band management electrical ports.
Support SNMPv11v22v3 (Simple Network Management Protocol), which can support the industry's general network management platform and iMC intelligent management center. Support CLI command line, Telnet, FTP, and support SSH2.0, SSL and other encryption methods, making management more secure.
It supports the standard Netconf interface and provides a programmable method for configuring and managing network devices. It makes it very convenient in the development of third-party software, and meets the user's needs for the openness and flexibility of the equipment.
Support sFlow function, can carry out refined statistics of messages, support SPAN/RSPAN/ERSPAN mirroring and multiple mirror observation ports, can analyze network traffic to take corresponding management and maintenance measures, so that the originally invisible network business application traffic becomes clear at a glance. Provide users with a variety of network flow analysis reports to help users optimize network structure and adjust resource deployment in time.
The H3C S5850 switch supports AAA and RADIUS authentication, and supports dynamic or static binding of user identification elements such as user accounts, IP, MAC, VLAN, and ports; supports real-time management of online users, timely diagnosis and Disrupt illegal online behavior.
The H3C S5850 switch provides enhanced ACL control logic, supports large-capacity ingress and egress port ACLs, and supports VLAN-based ACL issuance.
During the user configuration process, the waste of ACL resources is avoided.
Using H3C's S12500/S9820/S6800 switch based on the 100G platform as the data center core (Spine node), the access layer can use the S68000S5850 switch as the TOR switch (Leaf node) to provide a high-density 1GEE10GE server access solution. The S5850 switch supports high-density Gigabit ports. It can be used as an access TOR switch in the three-tier data center architecture. It is connected to the S12500/S9820/S6800 through the 10GE/40GE link in the uplink, providing 10GEE40GE server access, building a highly reliable, highly redundant ultra-large scale Data center network.
