Description

The Arista DCS-7280CR3-32D4-F is a high-performance 1RU data center switch router featuring 32 ports of 100GbE QSFP28 and 4 ports of 400GbE QSFP-DD uplinks. Built on the 7280R3 deep-buffer architecture, it delivers 4.8 Tbps throughput and 8GB of buffer memory for lossless forwarding in demanding spine, leaf, and peering environments. This model features front-to-rear airflow and dual AC power supplies, making it ideal for modern cloud, content delivery, and enterprise data center deployments requiring Layer 2 and Layer 3 scale with advanced routing, VXLAN overlay, and network virtualization capabilities.

Features

FAQs

Q: What port speeds and breakout configurations does the DCS-7280CR3-32D4-F support?
A: Each QSFP28 port supports 1G, 10G, 25G, 40G, 50G, and 100G speeds with flexible breakout options such as 4x25G or 4x10G. The four QSFP-DD ports support 100G, 200G, and 400G modes, and can interoperate with 100G QSFP28 modules for maximum deployment flexibility.

Q: Is this switch suitable for spine or leaf deployment in a data center fabric?
A: Yes, the DCS-7280CR3-32D4-F is designed as a universal spine and leaf switch. It delivers high-density 100G connectivity for leaf-to-server or leaf-to-spine, while the 400G uplinks are ideal for spine connectivity in large-scale ECMP or VXLAN overlay networks.

Q: What routing scale does the 7280R3 platform support?
A: The DCS-7280CR3-32D4-F leverages Arista FlexRoute technology to support over 1.3 million IPv4 routes in hardware, enabling full internet peering, DCI, and large-scale enterprise routing scenarios. Multiple forwarding profiles allow flexible table allocation for MAC, host, and routing entries.

Q: Does this model include power supplies and support redundancy?
A: Yes, the -F model includes two 1000W AC power supplies with front-to-rear airflow for full redundancy. Fans and power supplies are hot-swappable, ensuring uninterrupted operation during maintenance.

Q: What advanced features does Arista EOS provide on this switch?
A: Arista EOS on the 7280R3 includes VXLAN bridging and routing, MLAG for active-active Layer 2 designs, large-scale ECMP, wire-speed MACsec and IPsec encryption, Algorithmic ACLs, advanced sFlow telemetry, segment routing, EVPN, and deep integration with Arista CloudVision for automation and monitoring.
