3C S9827 high-density intelligent series switches is developed for data centers and cloud computing networks. It provides powerful hardware forwarding capacity and abundant data center features. It provides up to 64*800G ports or 128*400G and 1 out-of-band management ports. The switch supports modular power supplies and fan trays. By using different fan trays, the switch can provide field-changeable airflows.
With the rapid development of data center technology,the scale of data centers grows rapidly.
The current trends in datacenter networking is ultraroadband and lossless transmission.The H3C S9827 series switches conform to the development trend.They support ROCEv2, can be used in RDMA or AIGC network.
S9827 support visibility functions and cantransmit realtime resource information, RDMA statistics, and RDMA alarm information from switches to data center operation and maintenance platforms through protocols such as ERSPAN and gRPC. The operation and maintenance plat form cananalyze this realtime data to achieve functionssuchas network quality tracing, fault diagnosis, risk warning,architectura loptimization, and even automaticad just ment of network configurations to reduce network congestion, enabling datacenter operation and maintenance to movetowards automation.
The S9827 series switches includes two models:
S9827-64E(QSFP-DD800): 2U height with 1+1 power redundancy and 3+1 fan redundancy
S9827-64EP(OSFP800): 4U height with N+N power redundancy and 7+1 fan redundancy
S9827-128DH: 4U height with N+N power redundancy and 7+1 fan redundancy
Features
The switch offers high-density 800G/400G ports and a forwarding capacity as high as 102.4Tbps, which enables the switch to provide high-density server access in high-end data centers without oversubscriptions.
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 S9827 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.
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
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.
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.
