Arista DCS-7280CR3K-32P4-R Overview
DCS-7280CR3K-32P4-R is a fixed-configuration
1RU Arista 7280R3K switch/router designed for high-throughput data center and service provider environments. This model provides a mixed high-speed interface profile and is built for deployments that require
rear-to-front airflow (-R).
As part of the
7280R3K platform, this system is optimized for
large routing tables and is commonly deployed at the fabric edge and aggregation layers where scale, throughput, and predictable forwarding performance are required.
Key Hardware Characteristics
- Form factor: 1RU fixed-configuration switch/router
- Platform: Arista 7280R3K series (large route scale)
- Ports: 32 x 100GbE QSFP and 4 x 400GbE OSFP
- Airflow: Rear-to-front (-R)
- Deployment roles: Leaf/spine, aggregation, fabric edge, high-scale routing
Operational Use Cases
The DCS-7280CR3K-32P4-R is typically deployed in environments that require both high-speed connectivity and increased routing scale. Common use cases include large-scale data center fabrics, service provider aggregation, and routing-intensive edge deployments where airflow direction must align with rack design.
