Description

The Arista DCS-7280SR3-40YC6-F is a 1RU data center switch router delivering 800 Gbps non-blocking throughput with 40x 25GbE SFP28 ports and 6x 100GbE QSFP28 uplinks. Built on a next-generation VOQ ASIC with 2GB HBM2 packet buffer and 3.8µs latency, it provides full Layer 3 capabilities including BGP, MPLS, Segment Routing, EVPN, VXLAN, and 512-way ECMP. The -F suffix denotes front-to-rear airflow for standard data center cooling.

Features

Virtual Output Queue (VOQ) architecture eliminates head-of-line blocking
- 2GB HBM2 on-chip packet buffer for burst absorption and lossless forwarding
- Support for VXLAN network virtualization and EVPN with IRB
- Advanced telemetry: LANZ, Accelerated sFlow, INT, IPFIX, AEM, DANZ
- Hardware-based IEEE 1588 PTP (Precision Time Protocol)
- Zero Touch Provisioning (ZTP) for automated deployment
- CloudVision integration for network-wide visibility and management
- Comprehensive QoS with priority queuing and traffic shaping
- Full Internet routing table support with hardware-accelerated lookups
- MPLS and Segment Routing for advanced traffic engineering
- Energy-efficient design with redundant AC power supplies
- SFP28 fiber optics for long-reach, noise-immune connectivity

FAQs

Q: What is the difference between the -F and -R models?
A: The -F suffix indicates front-to-rear airflow (cool air enters from the port side, exhausts from the fan side), while the -R model features rear-to-front airflow. Choose based on your data center hot/cold aisle design.

Q: Can the 100G QSFP28 ports be used for 25G or 10G connectivity?
A: Yes, the 6x 100G QSFP28 uplinks support breakout configurations to 4x25G or 4x10G per port, allowing up to 24 additional 25G or 10G ports for flexible network design.

Q: What routing protocols and features does this switch support?
A: The 7280SR3-40YC6-F is a full Layer 3 switch router supporting BGP, OSPF, IS-IS, MPLS (LDP, RSVP-TE, BGP-LU), Segment Routing, EVPN with IRB, VXLAN with 512-way ECMP, and can hold over 2M IPv4 routes for Internet peering applications.

Q: Is this switch suitable for leaf-spine data center architectures?
A: Yes, the 7280SR3-40YC6-F is purpose-built for modern leaf-spine topologies, cloud networking, and data center interconnect applications with its deep buffers, low latency, and rich L2/L3 feature set.

Q: Does this model require software licensing?
A: The DCS-7280SR3-40YC6-F runs Arista EOS. Contact your Arista representative or XS Network Tech for current licensing requirements and subscription options for advanced features and support.
