H3C S6890-54HF can provide 48 1G/10G SFP+ ports, 6 100G QSFP28 ports (40G QSFP+ compatible) , 2 modular power supply slots, 5 fan slots, 2 out-of-band management ports, 1 console port and 1 USB port.

The S6890 switch series delivers industry leading 4G buffer designed to address burst traffic in Internet companies.

Virtualization technologies - IRF2

H3C patented virtualization technology IRF2 is designed for the requirement of unified switching architecture in datacenter. The technology delivers the following benefits:

High Availability (HA) - Patented hot standby technology to provide data backup and non-stop forwarding on the control plane and data plane, which improves availability, performance, service continuity and eliminates single-point failure.

Distribution - Multi-switch link aggregation to enable load sharing and backup over multiple uplinks, improving network redundancy and link utilization.

Easy Management - Single IP address management to simplify the device and topology management, improving operation efficiency and lowering network maintenance cost.

DC-oriented features

VXLAN (Virtual Extensible LAN) — VXLAN uses a MAC-in-UDP encapsulation method where the original Layer 2 package is added with a VXLAN header, and is then placed in a UDP-IP packet. With the help of MAC-in-UDP encapsulation, VXLAN tunnels Layer 2 network over Layer 3 network which provides two major benefits: higher scalability of Layer 2 segmentation and better utilization of available network paths.

MP-BGP EVPN (Multiprotocol Border Gateway Protocol Ethernet Virtual Private Network) uses standard-based BGP protocol as the control plane for VXLAN overlay networks, providing BGP based VTEP auto peer discovery and end-host reachability information distribution. MP-BGP EVPN delivers many benefits, such as eliminating traffic flooding, reducing full mesh requirements between VTEPs via the introduction of BGP RR, achieving optimal flow based end to end load sharing and more.

High-performance IPv4/IPv6 service capabilities

H3C S6890 switch series comes with IPv4/IPv6 dual-stack platform that provides sophisticated IPv4/IPv6 solutions by supporting multiple tunnels, IPv4/IPv6 Layer 3 routing protocols, multicasting, and policy-based routing.

Flexible choice of airflow

To cope with data center cooling aisle design, the H3C S6890 switch series 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.

Outstanding security control policies

H3C S6890 switch series supports AAA, RADIUS authentication and user account, IP, MAC, VLAN, port-based user identification of dynamic and static binding; Working with H3C iMC platform, it can conduct real time management, instant diagnosis and crackdown on illicit network behaviors.

H3C S6890 switch series supports enhanced ACL control logic, offers a large number of inbound and outbound ACLs and VLAN-based ACL assignment. This simplifies user configuration while saving ACL resources.

Multiple reliability protection

The S6890 switch series provides multiple reliability protection at both equipment and link levels. With overcurrent, overvoltage and overheat protection, all models have a redundant swappable power module, which enables flexible configuration of AC or DC power modules based on actual needs. The entire switch supports fault detection and alarm for power supply and fan, allowing fan speed to change to suit different ambient temperatures.

Excellent manageability

H3C S6890 switch series provides rich management interfaces, including console port, out-of-band management port and USB port. Management protocols such as SNMPv1/v2/v3 are supported aside from iMC Management Console. The network administrator may activate control through CLI, Web user interface and TELNET which gives maximum flexibility in accessing and managing the device. The administrator may also choose SSH2.0 and SSL encryption to shield the management sessions.
