Overview
The Arista
DCS-7280SR3K-48YC8 platform is available in multiple airflow and power configurations. The
DCS-7280SR3K-48YC8-F is the
front-to-rear airflow variant, commonly deployed as a high-performance leaf switch in modern 25/100GbE data center fabrics.
Key Hardware Characteristics
- Port configuration: High-density 25/100GbE switching, typically deployed with 25GbE SFP28 downlinks and 100GbE QSFP uplinks (exact supported optics/speeds depend on EOS and transceiver/cable selection).
- Operating system: Runs Arista EOS for automation, telemetry, and consistent operations across Arista switching platforms.
- Data center feature fit: Built for routed leaf/spine designs and large east-west traffic patterns where predictable low latency matters.
- Variant positioning: The R3K variant is commonly selected for environments that benefit from enhanced platform resources (confirm exact feature/resource requirements for your deployment).
Operational Use Cases
- Leaf role in 25/100GbE spine-leaf fabrics for data center and colo environments
- High-density server-facing 25GbE with 100GbE uplinks for aggregation and interconnect
- VXLAN/EVPN-style overlays and modern routed fabrics (feature availability depends on EOS version and licensing where applicable)
