Simple software upgrades can provide the new features required by users, offering unlimited possibilities for network expansion and timely evolution.
Rich Data Center Features
The S9857 switch fully supports RoCE features for lossless networks in data centers, including PFC, ECN, AI ECN, IPCC, iNOF, Agile Buffer, etc., creating a zero-loss, low-latency lossless network. It also supports typical box-to-box networking for 800G/400G lossless fabrics, meeting the demands of ultra-large-scale networking and low latency in data centers.
AI ECN dynamically adjusts the ECN threshold values of each transmission queue to meet varying resource demands based on real-time queue traffic, significantly enhancing data forwarding efficiency and achieving an intelligent, lossless, zero-loss low-latency computing network.
The S9857 switch supports FGLB (flexible global load balancing) capabilities, global lossless traffic scheduling, and ensures that overall network traffic forwarding remains optimized across link loads. It also supports lossless data plane self-healing (DPSH), enabling microsecond-level switching of data flows. The S9857 supports various load balancing capabilities, including multipath ECMP load balancing, per-flow load balancing, Spraylink per-packet load balancing, and path navigation.
Powerful Visualization Capabilities
With the rapid development of data center technologies, the scale of data centers is expanding quickly, making reliability and maintainability key bottlenecks for further expansion. The S9857 switches align with the trend of automated operations in data centers, supporting visualization features. Through protocols like ERSPAN and gRPC, real-time resource information, RDMA statistics, and RDMA alarm messages from the switches can be sent to the data center operation platform. The platform can analyze this real-time data to enable functions such as network quality tracing, fault diagnosis, risk warning, and architecture optimization, even allowing for automatic adjustments to network configurations to reduce congestion, thereby making the shift towards automated data center operations possible.
*Multiple Reliability Protection
The S9857 switch supports redundant hot-swappable power supplies and fans, with power supply supporting 1+1 redundancy and fans supporting 5+1 redundancy.
The S9857 switch features multiple reliability protections at both the device and link levels. It employs overcurrent protection, overvoltage protection, and overheat protection technologies, supporting hot-swappable redundant power modules that can be flexibly configured for AC or DC power supplies based on actual environmental needs. Additionally, the overall system supports fault detection and alarms for power and fans, provides automatic protection when a fan is not inserted to prevent chip damage due to high temperatures, and can automatically adjust fan speed based on temperature changes, resulting in high reliability for the device.
The S9857 switch supports nanosecond-level hardware automatic link switchover, enabling network devices to achieve automatic sensing, self-adjustment, and self-diagnosis functions, enhancing the automation level of the network, reducing the impact of faults on network stability and continuity, and ensuring efficient, stable, and secure network operations.
Rich QoS Strategies
The S9857 switch supports L2 (Layer 2) to L4 (Layer 4) packet filtering functions, providing traffic classification based on source MAC address, destination MAC address, source IP address, destination IP address, TCP/UDP port number, protocol type, and VLAN. Each 400G port supports multiple unicast and queues, offering flexible queue scheduling algorithms that can be set based on both port and queue, supporting five modes: SP (Strict Priority), WRR (Weighted Round Robin), SP+WRR, WFQ, and SP+WFQ. It also supports CAR (Committed Access Rate) functionality with a minimum granularity of 8Kbps. It supports port mirroring in both ingress and egress directions for monitoring packets on designated ports, copying packets to a monitoring port for network detection and troubleshooting.
Excellent Management Capabilities
The S9857 switch supports a rich set of management interfaces, such as Console, USB ports, and out-of-band (OOB) management copper ports.
The S9857 switch supports SNMPv1/v2/v3 (Simple Network Management Protocol), compatible with industry-standard network management platforms and the Intelligent Management Center (iMC). It supports CLI command line, TELNET, FTP, as well as encryption methods like SSH2.0 and SSL, enhancing management security.
The S9857 switch supports the standard Netconf interface, providing a programmable method for configuring and managing network devices. This makes it very convenient for third-party software development, meeting user demands for openness and flexibility in device management.
The S9857 switch supports sFlow and NetStream functionalities for detailed packet statistics, with support for SPAN/RSPAN/ERSPAN mirroring and multiple mirrored observation ports, allowing for network traffic analysis to take appropriate management and maintenance actions, making previously invisible network service application traffic clear. It can provide users with various NetStream analysis reports, helping optimize network structure and adjust resource deployment in a timely manner.
The S9857 switch supports real-time monitoring of Buffers and port queues, enabling dynamic adjustments for network operation and maintenance visualization.
Comprehensive Security Control Policies
The S9857 switch supports AAA and RADIUS authentication, dynamic or static binding of user identity elements such as user accounts, IP, MAC, VLAN, and port; it supports real-time management of online users in conjunction with H3C's iMC platform, allowing for timely diagnostics and dismantling of illegal network activities.
The S9857 switch provides enhanced ACL control logic, supporting large-capacity ingress and egress port ACLs, and supports VLAN-based ACL deployment, simplifying user configuration processes while avoiding wastage of ACL resources.
