Technologies virtualization IRF2

Using IRF2 you can virtualize up to two S12500X-AF switches into one logical switch fabric IRF. IRF2 has the following advantages:

High Availability (HA) – Patented hot standby technology realizes data redundancy and uninterrupted forwarding for the control plane and data plane. This improves availability and performance, eliminates critical elements that could cause system failure, and ensures uninterrupted service delivery.

Load balancing – the ability to aggregate links across different chassis provides load balancing and redundant connections across multiple backbone interfaces, which increases the degree of redundancy and channel capacity utilization.

Ease of management – management The entire IRF fabric is routed through a single IP address, simplifying device and topology management, increasing operational efficiency, and reducing network maintenance costs.

Technologies virtualization MDC< /strong>

MDC technology allows you to virtualize one S12500X-AF switch as several logical switches, which allows one core switch to be used to implement multiple services. 1:N virtualization maximizes switch resource utilization, reduces total network cost of ownership, and provides secure service isolation.

Features< /strong> for centers processing data

EVI – Ethernet Virtual Interconnect (EVI) technology is a technology for encapsulating MAC addresses in IP packets that provides Layer 2 connectivity between Layer 2 networks at remote sites using a routed IP network. It is used to combine geographically remote sites into a large virtualized data center, the nodes of which must be neighboring nodes in a layer 2 network.

FCOE – Fiber Channel over Ethernet provides the unification of heterogeneous local networks and storage networks in data centers. FCOE technology, together with CEE (Convergence Enhanced Ethernet), enables the interconnection of data networks, computer networks and storage networks in data centers, significantly reducing the cost of creating and expanding data centers.

VXLAN – Virtual Extensible LAN technology uses a method of encapsulating MAC addresses in UDP frames, in which a VXLAN header is added to the original layer 2 packet, and the resulting one is placed in the UDP packet -IP. By encapsulating MAC addresses within UDP frames, VXLAN technology allows Layer 2 network traffic to be tunneled through a Layer 3 network, providing two major benefits: greater scalability for Layer 2 segmentation and greater utilization of existing paths in the network.

MP-BGP EVPN – Multi-protocol edge routing for Ethernet VPNs uses the standard-based BGP protocol as the control plane for VXLAN overlay networks, enabling automatic peer discovery and distributing end-host reachability information using BGP-based VTEP. MP-BGP EVPN has many advantages, such as eliminating traffic flooding, eliminating the need for a mandatory mesh network between VTEP peers by supporting BGP RR, achieving optimal flow-based end-to-end load balancing, and much more.

Large table size for ARP/ND entries, MAC addresses and ACLs

Innovative< /b> design with several processor modules

Independent control processors , discovery and maintenance capabilities provide rich management capabilities and high availability with switchover in a matter of milliseconds:

Independent control processors – a powerful processor system that allows you to efficiently process multi-protocol packets and control packets, offering precise packet control and comprehensive protection against multi-protocol attacks.

Independent detection processors – provide highly reliable means of fast fault detection and recovery (FFDR) systems such as BFD and OAM, which are capable of interfacing with control plane protocols to failover in milliseconds and enable rapid convergence for uninterrupted service delivery.

Independent Maintenance Processors – Embedded Maintenance Subsystem (EMS), a processor system for intelligent power management, including sequential power cycling and device status monitoring. Cycling power on and off reduces power spikes, electromagnetic emissions, and power consumption, extending device life.

Tools to high availability for centers processing data

FFDR technology provides BFD and OAM functions that implement fast failover and protocol convergence . Data center level high availability features include:

BFD for VRRP/BGP/IS-IS/RIP/OSPF/RSVP/static routing

NSR/GR for OSPF/BGP/IS-IS/RSVP

Separation of control and data planes due to independent control processors and switching modules matrices.

Reservation according to the 1+1 scheme of control processors

Reservation according to scheme N+1 switching matrix modules

Redundancy scheme 1+1 fan modules

Redundancy according to the N+M power supply scheme

Multi-level means ensure security

The S12500X-AF Series switches use Quality of Service (QoS) policies to filter and limit traffic from data plane to the control plane. In the event of a denial of service attack, the switch is able to detect and protect important packets, discarding attack-related packets and maintaining normal operation

The switch supports a large number of access control lists (ACLs) without compromising transfers at transmission speeds. ACLs allow you to discover and control L2/IPv4/IPv6/MPLS traffic using various combinations of packet fields. H3C S12500X-AF Series switches support hardware-based MACsec (802.1ae) encryption technologies, the industry standard security technology to protect all traffic transmitted. in Ethernet channels.

Distributed buffering and < b>precision quality management quality service(QoS)

Distributed buffers for incoming traffic help cope with load surges. Each port provides precise bandwidth allocation and rate limiting for incoming traffic, with traffic distributed between input buffers. Distributed buffering makes full use of line card buffers, resulting in the best buffering performance.

Changing the network model from a client-server to a browser-server scheme led to an increase in traffic spikes. To cope with them, network devices must have increased buffering capabilities. The S12500X-AF series switches support 200 ms buffers to handle traffic bursts on each 10G interface, which meets the needs for processing such traffic in large data centers.

Each chip has a 4 GB buffer, for a total of up to 24 GB of buffer memory per line card.

Each of the line cards has a maximum of 96 thousand hardware queues and functions for detailed control of quality of service and traffic transmission. QoS functionality allows you to assign different priorities and queues to different users to implement differentiated service.

Comprehensive facilities services < b>and monitoring

Real-time status monitoring – the presence of a dedicated processor module for monitoring the status of switching matrix modules, channels backplane, communication channels for various services, main chips and memory. If a fault is detected, a corresponding message is sent to the system via the built-in EMS service subsystem

Card Isolation – the specified cards are isolated from the forwarding plane. At the same time, isolated cards continue to operate in the control plane, which allows the user to perform various management operations on them, such as real-time diagnostics and CPLD updates on isolated cards without affecting the functioning of the entire system

OAM functions for Ethernet – provide support for various Device-level and network-level fault detection methods

Energy Saving

Intelligent Processor-based Equipment Management System (EMS) – Provides intelligent power management and supports sequential power-on and turning off the power supply to the module, as well as monitoring the status of devices. Sequential (alternating) power cycling reduces spikes in power supply and electromagnetic radiation levels, increasing device life. In addition, the device health monitoring function allows you to isolate faulty and idle cards to reduce power consumption

Intelligent fan control – provides temperature information, calculates fan speed and transmits calculated speed information to fan modules. In addition, the system records fan speeds, fault alarms and adjusts fan speeds depending on configurations and areas, reducing energy consumption and noise levels, as well as extending fan life

Internal interface monitoring – automatically shuts down unused internal interfaces to reduce power consumption

RoHS Compliant – The S12500X-AF series switches meet EU RoHS safety standards.

The S12500X-AF series switches feature front-to-back airflow for efficient heat dissipation in data center environments.
