The S12500 switch series can work with H3C routers, switches, security devices, IMC, and H3Cloud to provide a wide variety solutionsHigh Availability (HA) - Patented hot standby technologyprovides data backup and non-stop forwarding on the control plane and data plane. It improves availability and performance eliminating single-point of failures, and ensure service continuity Distribution - Multi-chassis link aggregation to enable loadsharing and backup over multiple uplinks, improving redundancy and link utilizationEasy Management - A single IP address to manage the whole IRF fabric, which simplifies device and topology management, improving operating efficiency, and lowering network maintenance costTVirtualization technologies - IRF2Virtualization technologies - IRF3Features Advanced CLOS+ multi-grade multi-plane switching architecture•••••••••••••CLOS+ multi-grade multi-plane architecture, midplane free design, providing continuous bandwidth upgrade capability Supports industry first 48-port 40GE/ 100GE interfaces and can meet the existing and future application requirements of data centers•Adopts independent switching fabric modules and MPU engines to improve device availability and ensure bandwidth expansion••Increased I/O ports and centralized maintenance and managementReduced network management nodes Simplified cable deployment Data plane virtualizationIRF2 can virtualize up to four S12500 switches into one logical IRF fabric. IRF2 delivers the following benefits:IRF3 virtualizes core and access switches into one logical device. IRF3 delivers the following benefits:OverviewIndependent control engine - Uses a powerful CPU system that can efficiently process protocol and control packets, providing refined control for protocol packets and comprehensive protection against protocol packet attacks Independent detection engine - Provides highly reliable Fast Fault Detection and Restoration (FFDR) such as BFD and OAM, which can interact with protocols on the control plane toimplement millisecond-level failover and convergence, ensuring service continuityIndependent maintenance engine - Uses an intelligent Embedded Maintenance Subsystem (EMS), a CPU system that provides smart power management, including sequential power-on and power-off and device status check. Sequential power-on and power-off reduces power impulse, electromagnetic radiation, power consumption, and extends the device lifespan•••••••••••TRILL/SPB - Designed for building large flat Layer 2 networks for data centers to accommodate more servers. TRILL or SPB integrates the simplicity and flexibility of Layer 2 with the stability, scalability, and high performance of Layer 3EVI - EVI is a MAC-in-IP technology that provides Layer 2connectivity between distant Layer 2 network sites across an IP routed network. It is used for connecting geographically dispersed sites of a virtualized large-scale data center that requires Layer 2 adjacencyFCOE - Integrates heterogeneous LANs and storage networks in data centers. FCOE and CEE integrate data, computing, and storage networks in data centers, reducing the costs for building and expanding data centersVXLAN (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 pathsMP-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 reachabilityinformation distribution. MP-BGP EVPN delivers many benefits, such as eliminating traffic flooding, reducing full meshrequirements between VTEPs via the introduction of BGP RR, achieving optimal flow based end to end load sharing and more Large capacities for storing ARP/ND, MAC, and ACL entriesDC-oriented features••••••DC-class HAInnovative multi-engine designFFDR provides BFD and OAM functions to implement fast failover and convergence. The following lists the DC-class HA features:Independent control, detection, and maintenance engines provide powerful control capability and millisecond-level HA:BFD for VRRP/BGP/IS-IS/RIP/OSPF/RSVP/static routing NSR/GR for OSFP/BGP/IS-IS/RSVPSeparation of control and data planes through independent control engine and switching fabric module 1+1 redundancy for control engines N+1 redundancy for switch fabric modules 1+1 redundancy for fan trays N+M redundancy for power modulesSupports a large numbers of ACLs while ensuring line-speed forwarding. ACLs can identify and control L2/IPv4/IPv6/MPLS traffic by using combinations of packet fieldsMulti-level security protectionThe S12500 switch series use QoS policies to filter and limit traffic from data plane to control plane. During a DoS attack, the switch can identify and protect important packets and discard attack packets, ensuring normal operation••Virtualization technologies - MDCMDC virtualizes one S12500 switch into multiple logicalswitches, enabling multiple services to share one core switch. The 1:N virtualization maximizes switch utilization, reduces network TCO, and ensures secure isolation of services••••Distributed buffering and precise QoSDistributed ingress buffers accommodate burst traffic. Each port performs a precise bandwidth assignment and traffic shaping for incoming traffic, and distributes the traffic to ingress buffers. Distributed buffering can fully utilize the buffers of line cards to ensure best buffering performanceA network model change from C/S to B/S leads to increased volumes of burst traffic. Network devices must have larger buffering capabilities to support this. The S12500 series supports 200ms buffering of burst traffic per 10G interface, which can meet the burst traffic requirements of large data centersEach chip can support 4GB buffer, maximum of 24GB buffer per line cardEach line card supports a maximum of 96K hardware queues, refined QoS, and traffic management. QoS can assign different priorities and queues to different users to provide differentiated services•••Comprehensive maintenance and monitoringOnline state monitoring - Uses a dedicated engine to monitor the state of switch fabric modules, backplane channels, service communication channels, key chips, and storage. Once a failure occurs, it reports the failure to the system through EMS Card isolation - Isolates specified cards from the forwarding plane. The isolated cards still work on the control plane,allowing the user to perform management operations such as real-time diagnosis and CPLD upgrade on the isolated cards without affecting system operationEthernet OAM provides multiple device-level and network-level fault detection methods••OAAOAA provides an open service platform that supports multiple service cards, including next generation firewall and netstream cards. The integration of these cards to the switch allows for unified network security solutionsGreenIntelligent EMS engine system - Provides smart power management that supports sequential power-on andpower-off and device status check. Sequential power-on and power-off reduces power impulse and electromagneticradiation, and increases the lifetime of the device. Additionally, device status checks can isolate faulty and idle cards to reduce power consumption••••Smart fan management - Collects fan temperature, calculates fan speed, and assigns the calculated speed to the fan tray. In addition, it detects fan speeds, fault alarms, and performs speed adjustment based on configurations and area, reducing power consumption and noise, increasing the fan's lifetimeInternal interface monitoring - Automatically shuts down unused internal interfaces to reduce power consumptionRoHS compliance - The S12500 switch series meets the EU RoHS safety standardsThe S12500 switch series is designed with front to back air flow, satisfying highly efficient heat dissipation requirements in data centreSpecificationsEnterprise DC applicationProvides large-capacity forwarding through its multi-level switching fabric to completely meet the traffic forwarding requirements of large data centers.Provides HA mechanisms such as BFD and FRR to ensure the availability of data center networks.Work with other H3C switches, routers and security devices to offer a complete data center solution.•••As core devices in data center networks, the S12500 series features the following:resources10GE Base-Tserver10GE server S10500S5820V2-52QF 10G server GE serverFC storageIDC ApplicationH3C Technologies Co.
