Arista DCS-7280SR3-48YC8-R Overview
DCS-7280SR3-48YC8-R is a fixed-configuration
1RU Arista 7280R3 switch/router designed for high-density data center and service provider environments. This model provides a mix of 25GbE server-facing ports with 100GbE uplinks and is built for deployments requiring
rear-to-front airflow (-R).
As part of the
7280R3 platform, this system is commonly deployed at the leaf layer or aggregation edge where predictable forwarding performance and flexible uplink capacity are required.
