Description

The Arista DCS-7280R4-64QC-10PE-R is a high-performance data center switch router delivering 14.4 Tbps throughput with 64x 100GbE QSFP ports and 10x 800GbE OSFP ports. Purpose-built for cloud, AI/ML, and service provider networks, it features Virtual Output Queuing with 16GB deep packet buffers, FlexRoute engine for internet-scale routing, and rear-to-front airflow cooling. Ideal for leaf-spine topologies, storage networks, and high-bandwidth data center interconnects requiring wire-speed L2/L3 forwarding and deterministic low-latency performance.

Features

Virtual Output Queuing (VOQ) architecture eliminates head-of-line blocking
- FlexRoute engine with flexible forwarding table allocation for diverse network roles
- Layer 2 switching with MLAG for active-active redundancy
- Layer 3 routing with ECMP supporting up to 512-way load balancing
- EVPN-VXLAN overlay networking with bridging, routing, and gateway functions
- MPLS and Segment Routing support for carrier-grade deployments
- Algorithmic ACLs scaling to hundreds of thousands of policy entries
- Accelerated sFlow with full-rate sampling on all interfaces
- Comprehensive streaming telemetry for real-time network visibility
- Zero Touch Provisioning (ZTP) for automated deployment
- In-service software updates with stateful switchover
- MACsec, IPsec, and VXLANsec encryption (on 7280R4K variant)
- Precision Timing Protocol (PTP) IEEE 1588v2 and SyncE
- OpenConfig, YANG models, and REST API for programmability
- Native Linux shell access for custom automation and scripting

FAQs

Q: What is the difference between the 7280R4 and 7280R4K models?
A: The 7280R4K variant adds large-scale routing support (over 5 million IP routes), line-rate TunnelSec AES-256-GCM encryption on all QSFP and OSFP ports, and enhanced Algorithmic ACL capabilities. The base 7280R4 supports standard internet-scale routing without encryption.

Q: What does the -R suffix indicate in this SKU?
A: The -R suffix denotes rear-to-front airflow, meaning air flows from the fan side to the switch port side. This is also called reverse airflow. Models with -F suffix have front-to-rear airflow, while # suffix models ship with configurable airflow and require a louver kit to specify direction.

Q: What topologies and use cases is this switch designed for?
A: The 7280R4 is optimized for cloud data center leaf-spine architectures, AI/ML clusters, content delivery networks, service provider backbones, high-performance IP storage, and data center interconnects. It supports MLAG, ECMP, EVPN-VXLAN, MPLS, and Segment Routing for flexible deployment.

Q: What power supply options are available?
A: The switch supports hot-swappable dual power supplies including PWR-2411-AC (2400W, 200-240 VAC), PWR-2411-DC (2400W, -48 to -60 VDC), PWR-3211-HV (3200W, 200-277 VAC), and PWR-3211-DC (3200W, 240-380 VDC). All models ship with dual redundant PSUs.

Q: Does this switch require separate software licenses?
A: Arista EOS requires perpetual feature licenses. The 7280R4 platform is classified as FIX-4 in Arista's licensing framework and typically requires LIC-FIX-4 licenses for advanced features such as VXLAN, EVPN, MPLS, and enhanced automation capabilities. Base switching functionality is included.
