The H3C S5820V2 series switch is the latest 10 Gigabit Ethernet (10GE) offering made for the space constrained datacenter. Its “Top of Rack” design provides a rich set of features tailored for the datacenter, and all packed in standard 1U with record breaking 10GE port density, and 40G upstream port. The S5820V2 series is made for high density 10GE access in datacenter and cloud computing networks. It also fits nicely as the core or aggregation equipment of enterprise networks and MAN.

High 10GE port density
As client side network bandwidth grows, 10GE adapters are increasingly common in servers, and switches have to deliver a higher forwarding performance and provide more 10GE expansion space. S5820V2-52Q features 48 1/10G Base-T ports and four 40G QSFP ports, S5820V2-52QF and S5820V2-52QF-U switches feature 48 SFP+ optical ports, and four 40G QSFP ports. S5820V2-54QS-GE features four SFP+ optical ports and two 40G QSFP ports. By plugging in different modules, the 40G port can run as a single 40G port or four 10GE ports. That model supports up to 64 10GE ports and fulfils the need for high density access in the datacenter.
IRF2 (The Second-generation Intelligent Resilient Framework)
H3C S5820V2 series switches are 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 (10GE) 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.
VCF (Vertical Converged Framework)
S5820V2 supports VCF (Vertical Converged Framework) technology. VCF takes the box type switches as a remote interface board to the master switches, to achieve heterogeneously vertical extension. The entire system can be treated as a single logical device for unified management and use.
VCF can provide users with the following benefits:
· Unified Management: All members can be centrally configured and managed on master devices, with no need to physically be connected to each member and be configured individually.
· Unified security strategy: the entire network security policy only needs to be configured on the master device to avoid network device individual configuration and potential policy conflicts, significantly reducing security deployment workload.
· Reduce network layers: To support large-scale remote interface board expansion capabilities, the traditional three-layer network architecture can be simplified to be two layers through the VCF technology, simplifying the network's physical and logical complexity.
· Streamline service: Service configuration is based on a single logical device configuration, which can greatly simplify VLAN, IP, routing, MPLS VPN and other network planning considerations in the whole network.
· Easy maintenance: All access equipment configurations and software versions are automatically assigned by the master device, the new device that joins or leaves can be "hot swappable" with zero-configuration, and does not affect the normal operation of other equipment.
Rich data center features
· S5820V2 series switches support EVB (Edge Virtual Bridging), through VEPA (Virtual Ethernet Port Aggregator) mode, which redirect the data traffic generated by VMs (Virtual Machine) to the physical switch connected to the server for processing. Not only to achieve traffic forwarding between VMs, but also to solve the border management issues between VMs and the network connection.
· FCoE technology leverages Ethernet packet to carry FC packets. This means FC SAN and Ethernet LAN network can share the same network infrastructure, a good solution to solve the problems of coexistence between different types of network. S5820V2 series switch supports full FCoE and FC protocol stack. All downstream SFP + ports can be switched to FCoE ports, which communicate directly to the storage facility with FCoE interfaces. The downstream SFP+ ports of S5820V2-52QF-U model can also be switched to FC port to interoperate with FC SAN. Thus the FC SAN and Ethernet network are fully integrated, greatly simplifying the entire network infrastructure.
· TRILL (Transparent Interconnection of Lots of Links) is an innovative technology that changes the traditional way to build data center networks, it adopts layer 3 routing technology benefits, such as stable, scalable and high performance into an adaptable, but limited scope of layer 2 switching network, to establish a flexible, extensible, high-performance layer 2 network architecture. By using TRILL technology, S5820V2 series switches become the ideal choice to build a large, high-performance, scalable and supporting virtual machine live migration cloud data center network.
· S5820V2 series switches support DCB (Data Center Bridging), and support ISSU (In-service Software Upgrade), OAM (Operations, Administration and Maintenance) and Energy-Efficient Ethernet (EEE), and fully meet the high performance data center requirements, easy to manage with green energy consumption.
Flexible choice of airflow
· To cope with datacenter cooling aisle design, the H3C S5820V2 series switch 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.
· H3C S5820V2 series switch 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 behaviour.
· H3C S5820V2 series switch supports enhanced ACL control logic, which supports 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. S5820V2 series will also be able to 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 S5820V2 series switch comes with multiple device protection such as ampere protection and voltage surge protection and overheating protection to safeguard your network.
· Hot-pluggable power supply and fan module also add to the availability of the device. H3C S5820V2 series supports dual-power-supply and dual-fan; all models of power modules and fan modules are hot-swappable without interruption of the device operation. Multiple health-checks and alarms are available for power supply and fan, and fan speed will automatically adjust according to temperature changes.
· H3C S5820V2 series switch supports a rich management interface, including console, external network and USB. Management protocols such as SNMPv1/v2/v3 and RMON 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.

Networking application 1: Typical datacenter deployment
H3C employed 100G based S12500/12500-X series switch as the core of the datacenter, while the S12500 or S10500 may be used in the aggregation layer. Security and flow control can be maintained through the integrated firewall, firewall and load balancing multifunction modules. S5820V2 may be used in the access layer to provide high density 10GE server access.
