Virtualization technologies - IRF2
H3C patented virtualization technology IRF2 is designed for the requirement of unified switching architecture in datacenter. It can virtualize up to four physical S6890 switches into one logical IRF fabric. 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.
Large scalability of hardware table
The S6890 switch series uses its latest chipset to provide industry leading large scalability of hardware resource table. The series can support:
Up to 750K MAC address table and 350K ARP table
Up to 2M RIB and 250K FIB
Up to 20K ACL table shared by ingress and egress
FCoE—integrates heterogeneous LANs and FC SAN in data centers. FCoE and CEE integrate data, computing and storage networks in data centers, reducing the costs for building and expanding data centers.
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.
Comprehensive MPLS/VPLS capability
H3C S6890 switch series supports Multi-VRF function, which can be used as MCE equipment supporting L3 MPLS VPN and L2 MPLS VPN (Martini and Kompella). It also supports MPLS OAM function, which brings easier management and maintenance. Working with H3C intelligent Management Centre (iMC) MPLS VPN Manager, it allows easy MPLS deployment and maintenance.
H3C S6890 switch series also supports VPLS, VLL, hierarchicalVPLS and QinQ+VPLS access methods, providing end-to-endlayer2VPNaccesssolution.
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. The S6890 switch series is a mature commercial IPv6 product that has passed the IPv6 network access certification of the Chinese Ministry of Industry and Information Technology and the IPv6 Ready Phase II certification.
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. S6890 switch series can also take advantage of Unicast Reverse Path Forwarding (Unicast RPF). When the device receives a packet, it will perform the reverse check to verify the source address from which the packets are supposedly originated, and will drop the packet if such path doesn’t exist. This will curb the increasingly common originating address spoofing.
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.
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.
