Product Overview
The Arista 7280R4 Series represents the 7th generation of Arista's full-featured, deep-buffered fixed switch routers. These systems are purpose-built to address the needs of demanding Cloud, AI/ML, Data Center, multimedia, and Service Provider networks. Offering up to 25.6 Tbps of line-rate, non-blocking throughput and support for up to 32 ports of 800GbE, the 7280R4 Series provides exceptional performance and scalability.
Available in configurations optimized for data center workloads or large-scale routing, these switches support a wide range of interfaces from 25GbE to 800GbE, including 400G and 800G DWDM options for flexible expansion and simplified infrastructure management.
Key Features
- System Scale and Performance: Up to 32 x 800 GbE ports, 25.6 Tbps throughput, support for 400G/800G ZR/ZR+, and dedicated QSFP-Line System ports.
- Cloud Grade Routing: Enables secure internet peering, carrier edge VPN services, and next-generation EVPN services for 5G/MEC, CIN, and Metro environments.
- Data Center Optimized Design: Features ultra-deep packet buffers up to 32GB, Virtual Output Queues to eliminate head-of-line blocking, and highly efficient, redundant power and fan modules.
- Advanced Encryption: Supports wire-speed encryption with TunnelSec technology, offering MACsec, IPsec, and VXLANsec for secure data transmission.
- Arista EOS: Runs the same modular, state-sharing operating system as all Arista products, simplifying network administration and providing robust automation and telemetry capabilities.
- Precision Timing: Integrated support for Precision Timing Protocol (PTP, IEEE 1588v2) and Synchronous Ethernet (SyncE) for applications requiring precise synchronization.
- Accelerated sFlow: Provides advanced network telemetry, capacity planning, and security analysis with high-rate sampling capabilities.
Scalability and Flexibility
The 7280R4 Series offers flexible scaling options, including support for up to a 512-way ECMP for balanced traffic distribution across large leaf-spine designs. MLAG designs ensure high availability and cross-sectional bandwidth, while VXLAN gateway, bridging, and routing capabilities support next-generation data center designs.
With scalable routing tables and a wide choice of dense 100G and 800G interfaces, these switches provide maximum network design flexibility. The platform's advanced features, such as Algorithmic ACLs, enable rich policy control and efficient resource allocation.
