H3C S9827 Series Data Center Switches

High port density and powerful forwarding capacity

The switch offers high-density 800G/400G ports and 102.4Tbps forwarding capacity which enables the switch to provide high-density server access in high-end data centers without oversubscription.

These 800G/400G ports support splitting and downgrading function, such as 800G split into 400G*2, 800G split to 200G*4, downgrading to 400G, etc. It supports full-port insertion of LPO optical transceiver modules and intermixing of LPO and DSP transceiver modules.

Abundant Data Center Features

The switch supports abundant data center features, including:

H3C S9827 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, eliminate traffic flooding and reduce full mesh requirements between VTEPs via the introduction of BGP RR.

H3C S9827 series switches support ROCEv2 network, based on Priority-based Flow Control (PFC), ECN Enhanced Transmission Selection (ETS). Which ensures low latency and lossless RDMA applications and high-speed computing services.

H3C Multichassis link aggregation (M-LAG)

H3C S9827 series switches M-LAG, which enables links of multiple switches to aggregate into one to implement device-level link backup. M-LAG is applicable to servers dual-homed to a pair of access devices for node redundancy.

Streamlined topology: M-LAG 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.

Powerful Visibility

H3C S9827 series switches conform to the trend of automated data operation and maintenance, and support visibility of data center.

INT (Inband-Telemetry) is a network monitoring technology used to collect data from the device. Compared with the traditional network monitoring technology featuring one query, one reporting, INT requires only one-time configuration for continuous data reporting, thereby reducing the request processing load of the device. INT can collect timestamp information, device ID, port information, and buffer information in real time. INT can be implemented in IP, EVPN, and VXLAN networks.

Provides a variety of traffic monitoring and analytic tools, including sFlow, NetStream, SPAN/RSPAN/ERSPAN mirroring, and port mirroring to help customers perform precise traffic analysis and gain visibility into network application traffic. With these tools, customers can collect network traffic data to evaluate network health status, create traffic analysis reports, perform traffic engineering, and optimize resource allocation.

Supports realtime monitoring of buffer and port queues, allowing for visible and dynamic network optimization.

Supports PTP (Precision Time Protocol) to achieve highly precise clock synchronization.

Supports gRPC

Powerful SDN Capability

H3C S9827 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 S9827 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.

Excellent manageability

The switch improves system management through the following ways:

Provides multiple management interfaces, including the serial console port, USB port, two out-of-band management ports.

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.

Health perception function of optical transceiver modules

Supports optical transceiver modules health perception function, allowing real-time monitoring and perception of various indicators such as transceiver Receive/Transmit power, temperature, current, voltage, CRC, per-channel bit error rate, SNR, pre-FEC bit error rate, and statistics of uncorrectable bit errors. Collaborates with analyzers to detect and warn about issues like optical link attenuation and optical power loss in advance.

Supports optical port protection circuit.
