H3C H3C S6812/S6813 Series Data Center Switches
H3C S6812/S6813 high-density intelligent switch series is developed for data centers and cloud computing networks. It provides powerful hardware forwarding capacity and abundant data center features. The switch supports modular power modules and fan trays. By using different fan trays, the switch can provide field changeable airflows.
The switch is perfectly matched for high density 10GE, it can also operate as a TOR access switch on an overlay or integrated network.
The S6812/S6813 switch series has four models:
With the rapid growth of data center virtualization deployment, commercial deployment of 10 Gigabit servers and high-bandwidth applications, there are more and more demands for 100GE, 40GE, and 10 Gigabit networks. H3C S6813-48X6C and S6812-48X6C can support 48 10G ports and 6 100GE QSFP28 ports. S6813-24X6C and S6812-24X6C can support 24 10G ports and 6 100GE QSFP28 ports.
Facing the application requirements of the unified switching architecture of the data center, the series switches support the IRF2 technology, which virtualizes multiple devices into one logical.
The equipment has strong advantages in scalability, reliability, distributed and availability.
IRF2 not only can achieve a long-distance intelligent elastic architecture within a rack, across racks, and even across regions.
The switch supports abundant data center features, including:
H3C S681X series switches supports VXLAN (Virtual Extensible LAN), which provides two major benefits, higher scalability of Layer 2 segmentation and better utilization of available network paths.
H3C S681X series switches supports MP-BGP EVPN (Multiprotocol Border Gateway Protocol Ethernet Virtual Private Network) which can run as VXLAN control plane to simplify VXLAN configuration.
H3C S681X series switches support Priority-based Flow Control (PFC), Enhanced Transmission Selection (ETS) and Data Center Bridging eXchange (DCBX). These features ensure low latency and zero packet loss for FC storage, RDMA applications and high-speed computing services.
H3C S681X series switches support DRNI(M-LAG), which enables links of multiple switches to aggregate into one to implement device-level link backup. DRNI is applicable to servers dual-homed to a pair of access devices for node redundancy.
Streamlined topology: DRNI simplifies the network topology and spanning tree configuration by virtualizing two physical devices into one logical device.
Independent upgrading: The DR member devices can be upgraded independently one by one to minimize the impact on traffic forwarding.
High availability: The DR system uses a keepalive link to detect multi-active collision to ensure that only one member device forwards traffic after a DR system splits.
The switch uses industry-leading programmable switching chips that allow users to define the forwarding logic as needed.
Users can develop new features that meet the evolving trend of their networks through simple software updates.
Remote Direct Memory Access (RDMA) directly transmits the user application data to the storage space of the servers, and uses the network to fast transmit the data from the local system to the storage of the remote system. RDMA eliminates multiple data copying and context switching operations during the transmission process, and reduces the CPU load.
RoCE supports RDMA on standard Ethernet infrastructures. H3C S681X series switches support RoCE and can be used to build a lossless Ethernet network to ensure zero packet loss.
RoCE include the following key features，include PFC(Priority based Flow Control), ECN(Explicit Congestion Notification), DCBX(Data Center Bridging Capability Exchange Protocol), ETS(Enhanced Transmission Selection).
H3C S681X series switches adopt the next-generation chip with more flexible Openflow FlowTable, more resources and accurate ACL matching, which greatly improves the software-defined network (SDN) capabilities and meet the demand of data center SDN network.
H3C S6813 series switches can interconnect with H3C SeerEngine-DC Controller through standard protocols such as OVSDB, Netconf and SNMP to implement network automatic deployment and configuration.
H3C S681X series switches supports AAA, RADIUS and user account based authentication, IP, MAC, VLAN, port-based user identification, dynamic and static binding; when working with the H3C iMC platform, it can conduct real time management, instant diagnosis and crackdown on illicit network behavior.
H3C S681X series switches supports enhanced ACL control logic, which enables an enormous amount of inbound and outbound ACL, and delegate VLAN based ACL. This simplifies user deployment process and avoids ACL resource wastage. S681X series switches can also take advantage of Unicast Reverse Path Forwarding (Unicast RFP). When the device receives a packet, it will perform the reverse check to verify the source address from which the packets are supposedly originated, and will drop the packet if such path doesn’t exist. This can effectively prevent the source address spoofing in the network.
To cope with data center cooling aisle design, the H3C S681X series switches comes with flexible airflow design, which features bi-cooling aisles in the front and back. Users may also choose the direction of airflow (from front to back or vice versa) by selecting a different fan tray.
The switch improves system management through the following ways:
Provides multiple management interfaces, including the serial console port, mini USB console port, USB port, two out-of-band management ports, and two SFP ports. The SFP ports can be used as in-band management port through which encapsulated sampling packets are sent to the controller or other management devices for deep analysis.
Supports multiple access methods, including SNMPv1/v2c/v3, Telnet, SSH 2.0, SSL, and FTP.
Supports standard NETCONF APIs that allow users to configure and manage the switch, enhancing the compatibility with third-party applications.
