These features ensure low latency and zero packet loss for FC storage and high-speed compute services.
H3C S6800 series switches support transparent multi-link technology ( TRansparent Interconnection of Lots of Links, TRILL). TRILL is an innovative solution that changes the traditional way of building data center networks. Leveraging TRILL technology, the S6800 Series switches are ideal for building large, high-performance, scalable cloud data center networks with support for live virtual machines.
Technology intelligent fault-tolerant architecture< b>H3C IRF2
Excellent scalability: with IRF2, device aggregation can be done on a plug-and-play basis ” by simply adding one or more switches to the IRF2 stack and enabling IRF2 stacking mode on the new device. New devices will be managed through the same IP address, providing a scalable, easy-to-manage data center networking platform.
Highly reliable : The IRF2 stack backs up the entire control plane and data plane to achieve uninterrupted Layer 3 forwarding, greatly improving the reliability and performance of the IRF2 stack, eliminating critical elements that could cause system failure, and avoiding system failures. organization.
Load balancing: IRF2 supports link aggregation across devices, allowing connections to higher and lower level devices using multiple physical links . This creates another level of redundancy in the network and promotes fuller use of network resources.
Technology aggregation< /strong> connections to various devices H3C (DRNI)
H3C S6800 series switches support DRNI technology, which allows you to combine channels on different switches into one connection in order to reserve channels at the device level. DRNI can be used for servers with two network interfaces connected to a pair of access devices for host redundancy purposes.
Optimized topology: DRNI simplifies network topology and protocol configuration spanning tree by virtualizing two physical devices into one logical device.
Independent update: Devices in a distributed fault-tolerant group can be updated independently of each other, one by one, in order to minimize the impact on traffic forwarding.
High availability: In a distributed fault-tolerant group system, a keepalive message channel is used to detect collisions when multiple devices are active to forward traffic after the system division was carried out by only one of the devices in the group.
RoCE (RDMAonover converged Ethernet)
Remote Direct Memory Access (RDMA) technology directly transfers user application data to server storage space, and at the same time uses the network to quickly transfer data from the local system to the memory of a remote system. RDMA eliminates repeated data copying and context changing operations during transmission, reducing the load on processors.
In RoCE technology, the RDMA mechanism is implemented within the standard Ethernet infrastructure . The H3C S6850 switches support RoCE technology and can be used to create a Lossless Ethernet transport network that guarantees zero packet loss.
RoCE technology provides the following main Features: Priority-based Flow Control (PFC), Explicit Congestion Notification (ECN), Data Center Bridging eXchange (DCBX), Enhanced Transmission Selection, ETS) for strip control.
Powerful capabilities< b>SDN
H3C’s S6800 series switches feature next-generation hardware with more flexible Openflow flow tables, additional resources, and more precise access control list (ACL) mapping, dramatically expanding the capabilities of software-defined networking (SDN) in to meet the SDN requirements of data centers.
H3C S6800 Series switches support the standard Openflow protocol, which can be included and managed via H3C VCFC Controller, H3C Cloud, or other common cloud platforms or third-party controllers, allowing you to flexibly tailor your network to your organization’s needs and automate management.Users and third-party controllers can use standard interfaces to design and implement a custom network management strategy to quickly grow your business , expanding functionality and intelligent device management.
MACsec
H3C’s S6800 Series switches support hardware-based MACsec (802.1ae) encryption technology, the industry standard security technology for protecting all traffic on Ethernet links. Compared to traditional application-level software encryption technologies, MACsec technology secures point-to-point Ethernet links between directly connected nodes and is capable of detecting and preventing most security threats.
Excellent policies ensuring security< /strong>
H3C S6800 Series switches support Authentication, Authorization and Accounting (AAA), RADIUS authentication, Account authentication users, user authentication by IP address, MAC address, VLAN and port, as well as dynamic and static binding; When paired with the H3C iMC network management platform, they provide real-time management, instant diagnostics, and mitigation of unacceptable network behavior.
S6800 Series switches from H3C support advanced management capabilities based on access control lists (ACL); You can define a large number of ACLs for each incoming and outgoing port, and you can also use ACLs in conjunction with a VLAN. This simplifies user registration and avoids wasting ACL resources. Besides, The S6800 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. This helps combat the increasingly common source address spoofing attack pattern.
Flexible choice directions airflow
To adapt to the cooling flow patterns in data center aisles, H3C’s S6800 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.
Various < b>means increasing reliability
H3C’s S6800 series switches implement a variety of protection schemes to improve reliability at both the switch and link levels. All models, equipped with overcurrent, overvoltage and overtemperature protection, support redundant, removable power supplies, giving you the flexibility to select AC or DC power supplies based on your actual needs. All switches in the line support fault detection and alarming for power supplies and fan modules, as well as adjusting fan speed based on ambient temperature.
Excellent< /strong> capabilities control
H3C’s S6800 series switches provide a wide range of management interfaces, including a console port, an external network port, and a USB port. In addition to the iMC management console, SNMPv1/v2/v3 management protocols are supported. The network administrator can access the management interface via Command Line Interface (CLI), TELNET, SSH, SNMP, RESTful API, which provides maximum flexibility in terms of accessing and managing the device.
