Overview

The Arista DCS-7280CR3-32D4-F is built for scalable, high-density environments, making it an ideal solution for modern data centers, cloud service providers, and enterprises that require advanced routing, switching, and automation capabilities.

The Arista DCS-7280CR3-32D4-F is part of Arista's 7280R3 Series, which is designed for high-performance, flexible, and scalable networking in modern data centers. This switch provides advanced Layer 2 and Layer 3 capabilities with high-density 100GbE interfaces.

 

Specifications

  • Model: Arista DCS-7280CR3-32D4-F
  • Series: Arista 7280R3
  • Form Factor: 1 RU (Rack Unit)
  • Airflow: Front-to-back airflow (denoted by the "F" in the model number).

Port Configuration:

  • 32 x 100GbE QSFP28 ports:
    • Each QSFP28 port can support 100GbE, 40GbE, or breakout configurations such as 4x25GbE or 4x10GbE for flexibility.
  • 4 x 400GbE QSFP-DD ports:
    • Each port can support 400GbE or be broken out into smaller port speeds, such as 4 x 100GbE, providing future-proofing for growing bandwidth demands.

Performance:

  • Switching Capacity: 12.8 Tbps (Terabits per second).
  • Forwarding Rate: 5.7 Bpps (Billion packets per second).
  • Latency: Ultra-low latency, suitable for environments requiring fast and consistent network performance.

Buffering:

  • Packet Buffer Memory: 64 MB dynamically allocated per port group, designed to handle traffic bursts and ensure smooth performance in congested environments.

Layer 2 and Layer 3 Features:

  • Layer 2:

    • Supports VLANs, including 802.1Q VLAN tagging.
    • Link Aggregation (LACP) with up to 64 ports per group.
    • Spanning Tree Protocol (STP, RSTP, MSTP).
    • Jumbo Frames up to 9216 bytes.
  • Layer 3:

    • Supports advanced IPv4 and IPv6 routing, including OSPF, BGP, IS-IS, and RIP.
    • VRF (Virtual Routing and Forwarding) for Layer 3 virtualization.
    • Equal-Cost Multi-Path (ECMP) routing with up to 128-way paths for load balancing.

Advanced Features:

  • VXLAN: Hardware-based VXLAN support for scalable Layer 2 network virtualization over Layer 3.
  • Quality of Service (QoS):
    • Supports up to 8 egress queues per port.
    • Provides flexible traffic prioritization, policing, and shaping.
  • Security:
    • Access Control Lists (ACLs) for filtering traffic at Layers 2-4.
    • Control Plane Policing (CoPP) to protect the control plane.
    • MACsec (802.1AE) encryption for secure data transmission on selected interfaces.

Telemetry and Monitoring:

  • Arista Latency Analyzer (LANZ) for real-time network performance analysis.
  • sFlow and Streaming Telemetry support for detailed traffic monitoring and analysis.

Management and Automation:

  • Operating System: Runs Arista’s Extensible Operating System (EOS), which provides advanced programmability, real-time network monitoring, and automation capabilities.
    • eAPI (Extensible API): Supports automation through REST APIs.
    • CloudVision: Integrates with Arista's CloudVision for network-wide automation, visibility, and telemetry.
    • Zero Touch Provisioning (ZTP) for automated deployment.

Power and Environmental:

  • Power Supplies: Dual, hot-swappable, redundant power supplies (AC or DC).
  • Typical Power Consumption: Approximately 500W (varies based on configuration and traffic).
  • Cooling: Hot-swappable fan trays with front-to-back airflow.

Physical Dimensions:

  • Dimensions: 1.75 inches (4.45 cm) height x 19 inches (48.26 cm) width x 18 inches (45.72 cm) depth.
  • Weight: Approximately 26.2 lbs (11.9 kg).

Use Cases:

  • Data Center Spine/Leaf Architectures: Ideal for deployment in high-performance, scalable data center topologies.
  • Enterprise Core and Aggregation: Suitable for large-scale enterprises needing high-density, low-latency switching with advanced routing capabilities.
  • Cloud and Virtualization Environments: VXLAN and other overlay technologies make it an excellent fit for cloud data centers.

Key Features:

  • High-density 100GbE and 400GbE ports: Supports flexible configurations for cloud and enterprise data centers.
  • Advanced Layer 2 and Layer 3 routing: Provides a full suite of features for high-performance routing and switching.
  • Low latency: Designed for latency-sensitive applications such as high-frequency trading (HFT) and real-time data analytics.
