7500R3 Series 24 port 400GbE OSFP wirespeed line card (spare)
Processor and interface modules are functional components of Arista networking equipment designed to build high-performance, scalable and fault-tolerant networks. Their main task — Provision of processing, switching and routing network traffic, as well as supporting centralized management and network protocols.
Processor modules (Supervisor Modules)
Processor modules are responsible for managing the entire switch system, including the operation of the operating system, network protocols, automation tools, security and monitoring functions. Basic characteristics:
- Hardware support for multitasking data processing.
- Integration with a network operating system EOS (Extensible Operating System), which ensures stability and rel >work.
- Support for layer protocols L2/L3, including BGP, OSPF, IS-IS, MPLS, EVPN and VXLAN.
- Built -in telemetry and analytics mechanisms designed to monitor the network performance and detect real -time deviations.
- Support for centralized management platforms, including Arista CloudVision.
Processor modules installed in the chassis of the series 7500R, 7800R and 7300X, Provide high traffic density and are intended for use in large data centers, operator networks and cloud infrastructures.
Interface modules (Line Cards)
Interface modules are designed to organize physical connection to the network and ensure traffic processing at high transmission speeds. Various port configurations, including 10GBE, 25GBE, 40GBE, 100GBE and 400GbE. Characteristics:
- Support for modules SFP/SFP+, QSFP/QSFP28/QSFP-DD.
- Optimization for architecture Spine-Leaf and scenarios of use in highly executed date centers.
- The possibility of "hot replacement" without the need to stop the system.
- Hardware implementation of switching functions at 2 and 3 with minimal delays and high bandwidth.
- Support for automation and software-determined networks (SDN) through integration with API and management means.
Interface modules are compatible with ARISTA chassis and can be installed depending on the requirements for port density, bandwidth and type of interfaces.
Reliability and scalability
ARISTA equipment, including processor and interface modules, is developed taking into account the requirements for high availability, reservation of components and continuity of maintenance. Support for modular architecture allows for upgrades and performance increases without replacing the entire system. Also trans >ANVERTHED RESERVATION OF THE MAIN SUBSTANTIONS AND INTERLATUAL DUE OF TRAINING REFUND.
Scope
Modules are intended for use in large -scale corporate networks, communication operators, cloud environments and infrastructures with high productivity, failure resistance and network safety. Their application provides centralized control, flexibility of adjustment, stability to loads and support of modern network technologies.
