Description

The Arista DCS-7280PR3-24-F is a high-performance 1RU data center switch router featuring 24x400GbE OSFP ports with 9.6Tbps switching capacity and 4 billion packets per second forwarding rate. Designed for spine and leaf architectures, it delivers ultra-low 3.8 microsecond latency with deep 16GB packet buffering and supports flexible port breakout to 96x100G. With front-to-rear airflow, redundant hot-swappable 1500W AC power supplies, and Arista EOS software, this switch router is ideal for modern hyperscale data centers requiring wire-speed Layer 2 and Layer 3 performance.

FAQs

Q: What is the difference between the DCS-7280PR3-24-F and the 7280DR3 models?
A: The DCS-7280PR3-24-F uses OSFP 400G ports while the 7280DR3 models use QSFP-DD 400G ports. Both deliver the same 9.6Tbps performance and support breakout to 96x100G, but OSFP connectors offer better thermal performance for sustained high-speed workloads in dense deployments.

Q: Can this switch operate in both spine and leaf roles?
A: Yes, the 7280R3 is a universal spine and leaf platform with the Arista FlexRoute engine, supporting full Layer 2 and Layer 3 routing. It can handle up to 1.3 million IPv4 routes in L3 mode, making it suitable for both leaf switches in VXLAN fabrics and spine routing applications.

Q: What licensing is required for advanced routing features?
A: The DCS-7280PR3-24-F supports FlexRoute functionality. For advanced features like full routing tables beyond 256K routes, EVPN, VXLAN, Segment Routing, and advanced MPLS, you may need to purchase FlexRoute or FlexRoute-Lite licenses separately depending on your scale and feature requirements.

Q: Does this model support VXLAN and network virtualization?
A: Yes, the 7280R3 Series fully supports VXLAN for data center overlay networks, along with EVPN for control plane, allowing you to build scalable multi-tenant data center fabrics. It also integrates with Arista CloudVision for centralized management and automation.

Q: Is the DCS-7280PR3-24-F compatible with existing 100G infrastructure?
A: Absolutely. Each 400G OSFP port can be broken out into 4x100G connections using appropriate breakout cables or transceivers, giving you up to 96x100G ports. This provides excellent investment protection and flexibility for mixed-speed deployments.
