Product overview

The Arista DCS-7280CR2A-30-F belongs to the 7280R2 Series, purpose-built for demanding data center environments requiring ultra-low latency and high throughput. It features 30 QSFP100 ports supporting 100GbE with breakout to 10/25GbE via FC/RS FEC, achieving 6.4Tbps full-duplex switching capacity and sub-microsecond latency. AlgoMatch hardware acceleration optimizes programmable forwarding for complex traffic patterns in cloud-scale deployments. Expanded memory and SSD support enable stateful tables for EVPN, VXLAN, MPLS routing at internet scale. FlexRoute engine provides scalable L3 routing with multi-core Jericho2+ ASIC. 1RU form factor with front-to-rear airflow, hot-swappable PSUs/fans ensures reliability in dense racks. Ideal for spine/leaf architectures, HPC clusters, and service provider peering where wire-speed performance and deep buffers handle east-west traffic bursts effectively.

Frequently asked questions

What is the port configuration and switching capacity of DCS-7280CR2A-30-F?

Features 30x QSFP100 ports supporting 100GbE natively or breakout to 120x10/25GbE with FC/RS FEC, delivering 6.4Tbps full-duplex switching capacity. Jericho2+ ASIC ensures non-blocking wire-speed forwarding with 16GB shared buffer for bursty data center traffic.

What AlgoMatch capability does this switch provide?

AlgoMatch-1 accelerates user-defined match-action pipelines in hardware, reducing latency for custom forwarding like ACLs, QoS, and telemetry. Complements EOS programmability for stateful services without CPU overhead in high-scale environments.

What airflow and power redundancy options are available?

Front-to-rear airflow in 1RU chassis with 2x hot-swappable AC PSUs (1+1 redundant). Supports PWR-1611-DC for DC power. Operating temperature 0-40°C with high-speed fans for dense deployments.

How does it support cloud-scale routing and overlays?

FlexRoute with expanded memory/SSD stores massive FIB/Adj tables for BGP/EVPN. VXLAN, MPLS, segment routing natively hardware-terminated. Multi-core CPU runs EOS for advanced orchestration and zero-touch provisioning.

What management and monitoring features are included?

1x 100/1000BASE-T mgmt port, 1x RS-232 console, 2x USB. EOS provides sFlow/IPFIX, TCPDump, event monitoring, CLI scheduler. Optional 120GB SSD for stateful logs and remote troubleshooting.

Is it suitable for spine deployments in leaf-spine fabrics?

Yes, 30x100G ports provide high radix for spine role with 6.4Tbps throughput. Low latency AlgoMatch optimizes ECMP hashing and elephant flow detection, scaling to 100,000s of endpoints reliably.
