H3C S6890 Series Data Center Switches

High density 10G/40G/100G access with large buffer

H3C S6890-30HF can provide 24 1G/10G SFP+ ports, 6 100G QSFP28 ports (40G QSFP+ compatible), 2 modular power supply slots, 4 fan slots, 2 out-of-band management ports, 1 console port and 1 USB port.

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.

H3C Distributed Resilient Network Interconnection (DRNI)

H3C S6890 switch series support DRNI, 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.

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.

Performance and scalability

The typical data center application is an EVPN-VxLAN design,S12500G-AF or S12500X-AF swithes work as spine or spine/border, S68XX series work as leaf and border or ED. From this design ,the users can get a non-blocking large L2 system.
