What port configuration does the DCS-7280QRA-C36S-R provide?

Features 36x 40GbE QSFP+ ports (configurable as 18x 40GbE breakout or 144x 10G SFP+/48x 25G) and 12x 100GbE QSFP28 uplinks. Flexible optics support 10/25/40/50/100GbE speeds for mixed server and spine connectivity in data centers.

What is the switching capacity and buffer size?

Delivers 2.88Tbps full-duplex switching with 4GB shared buffer per system. Non-blocking architecture ensures wire-speed forwarding across all ports, ideal for high-bandwidth east-west traffic in leaf-spine deployments.

What is AlgoMatch and its benefits?

AlgoMatch is hardware-accelerated regex processing engine matching complex patterns at 40/100GbE line rate without CPU overhead. Enhances security ACLs, deep packet inspection, and telemetry for real-time threat detection in high-speed networks.

What airflow direction and power options are available?

Rear-to-front airflow (R to F) with dual hot-swappable AC PSUs included. Configurable for front-to-rear via # variant; supports high availability with N+1 redundancy for mission-critical data centers.

What routing scale does it support?

FlexRoute engine provides over 2M IPv4 routes, 768K host routes, BGP/OSPF/IS-IS. Scales for internet peering and large-scale L3 fabrics with MLAG for non-stop forwarding.

Is it compatible with Arista EOS and management tools?

Runs EOS 4.x with CloudVision for zero-touch provisioning, configuration rollback, and advanced monitoring including sFlow, LANZ microburst detection, and DANZ mirroring for comprehensive network visibility.

Product overview

The Arista DCS-7280QRA-C36S-R is a high-performance 1RU data center switch router from the 7280RA Series, featuring 36x 40GbE QSFP+ ports (flexible breakout to 18x 40GbE or 144x 10G/48x 25G) and 12x 100GbE QSFP28 uplinks, providing 2.88Tbps full-duplex switching capacity with 4GB shared buffer. AlgoMatch technology accelerates regex pattern matching for security and monitoring at line rate. Rear-to-front airflow ensures efficient cooling in standard racks. Supports EOS 4.x with FlexRoute for internet-scale routing (up to 2M IPv4 routes), VXLAN, BGP, OSPF, and advanced QoS including PFC/ETS. Ideal for leaf-spine topologies, cloud-scale networking, and low-latency HPC environments requiring wire-speed L2/L3 forwarding, DANZ monitoring, and CloudVision management.
