Flexible port combination
As network bandwidth tremendously grows, 10GE adapters are increasingly common in servers. The need of delivering high forwarding performance and providing more 10/40/100 GE expansion space has become essential.
H3C S6800-4C is built to cope with the need providing four module slots, and supporting high density 10G SFP+ fiber, 1/10G Base-T copper and 40G QSFP+ flexible configuration combination. The S6800-4C can also support a maximum of 96 10G and 8 40G ports, or 32 40G ports and can even support 96 FC/FCoE/Ethernet universal ports through its flexible FC interface module.
H3C S6800-2C can support a maximum of 48 10G and 6 40G ports or 18 40G ports. Through its flexible FC interface module, S6800-2C can even support 48 FC/FCoE/Ethernet universal ports.
For 100G uplink, the S6800-54HF/HT can support fixed 48 10G Base-X or Base-T and 6 100G QSFP28 ports.
For 40G uplink, the S6800-54QF/QT can support fixed 48 10G Base-X or Base-T and 6 40G QSFP28 ports.
S6800-32Q features 32*40G QSFP+ port, via 40G to 10G cable, supporting a maximum 104 10G ports.
Intelligent Resilient Framework 2 (IRF2)
H3C S6800 switch series is pre-built with Intelligent Resilient Framework 2 (IRF2). IRF2 provides the following benefits:
High scalability: With IRF2, plug-n-play device aggregation can be achieved by adding one or more switches into the IRF2 stack and enabling IRF2 stacking on the new device. New devices can be managed with a single IP, and upgraded at the same time to reduce network expansion cost.
High reliability: The IRF2 patented 1:N backup technology allows each slave device in the IRF2 stack to serve as the backup of the master, creating control and data link redundancy, as well as uninterrupted layer-3 forwarding. This improves the reliability, avoids unplanned business downtime and serves to improve overall performance. When the master device fails, traffic remains uninterrupted.
Load balancing: IRF2 supports cross-device link aggregation, upstream and downstream can be connected to more than one physical link, which creates another layer of network redundancy and boosts the network resource utilization.
Availability: H3C Implements IRF2 through standard Forty Gigabit Ethernet (40GE) or Ten Gigabit Ethernet (10GE) ports which allocates bandwidth for business and application access and reasonably splits local traffic and upstream traffic. IRF2 rules can not only be obeyed within and across the rack, but also across the LAN.
Data Center-Oriented Features
FCoE (Fiber Channel over Ethernet) technology leverages Ethernet packet to carry FC packets. This means FC SAN and Ethernet LAN network can share the same network infrastructure, which is a good solution to solve the problems of coexistence between different types of network. S6800 switch series supports full FCoE and FC protocol stack. All downstream SFP + ports can be switched to FC port to interoperate with FC SAN. As the FC SAN and Ethernet network are fully integrated, the entire network infrastructure is greatly simplified.
TRILL (Transparent Interconnection of Lots of Links) is an innovative technology that changes the traditional way to build data center networks. It incorporates the benefits of layer 3 routing technology, such as stable, scalable and high performance into an adaptable, but limited scope of layer 2 switching network. The end result is flexible, extensible, high-performance layer 2 network architecture. By using TRILL technology, S6800 switch series becomes the ideal choice to build a large, high-performance, and scalable cloud data center networks that support live virtual machines.
SDN (Software Defined Network) is an innovative network architecture that simplifies network management and reduces maintenance complexity. This is accomplished by separating network control layer and network forwarding layer through OpenFlow. More importantly, it implements flexible network flow control and provides a well-defined network platform for core network application and innovation.
H3C S6800 switch series supports DCB (Data Center Bridging), ISSU (In-service Software Upgrade), OAM (Operations, Administration and Maintenance) and EEE (Energy-Efficient Ethernet) . It fully meets the high performance data center requirements, and is easy to manage with green energy consumption.
H3C S6800 switch series supports VXLAN (Virtual Extensible LAN), VXLAN uses a MAC-in-UDP encapsulation method where the original Layer 2 package is added 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. This provides two major benefits, higher scalability of Layer 2 segmentation and better utilization of available network paths.
H3C S6800 switch series supports 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.
H3C S6800 switch series supports the intelligent caching technology. Its hardware implements intelligent distribution of traffic load, while utilization ratio increases up to five times than traditional method. In addition, S6800 employs intelligent hardware entry technology to achieve MAC/ARP/IP routing FIB table adjusts dynamically, and entry specification (such as MAC maximum up 288K) increased by 10 times compared with traditional switches. S6800 also supports intelligent hash technology. Under heavy network traffic, it can significantly eliminate network polarization and load imbalances. S6800 switch series uses high-performance multi-core CPU architecture and modular software operating platform to achieve greater flexibility when scheduling tasks with different priorities.
Flexible choice of airflow
To cope with data center cooling aisle design, the H3C S6800 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 S6800 switch series supports AAA, RADIUS and user account based authentication, IP, MAC, VLAN, port-based user identification, dynamic and static binding; when working with the H3C iMC platform, it can conduct real time management, instant diagnosis and crackdown on illicit network behavior.
H3C S6800 switch series supports enhanced ACL control logic, which enables an enormous amount of in-port and out- port ACL, and delegate VLAN based ACL. This simplifies user deployment process and avoids ACL resource wastage. S6800 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.
H3C S6800 switch series supports hardware level encryption technology MACsec (802.1ae), which is an industry-standard security technology that provides secure communication for all traffic on Ethernet links. Compared with traditional application based software encryption technology, MACsec provides point to-point security on Ethernet links between directly connected nodes and is capable of identifying and preventing most security threats.
H3C S6800 switch series provides multiple reliability protection at both switch and link levels. With overcurrent, overvoltage, and overheat protection, all models have a redundant pluggable 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 S6800 switch series provides a rich management interface, including console, external network and USB. Management protocols such as SNMPv1/v2/v3 are supported aside from iMC Management Console. The network administrator may activate control through CLI, Web 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 session.
