Arista DCS-7280R4-64QC-10PE-F | 7280R4 64-Port 100G + 10-Port 800G Switch, 14.4Tbps

Q: What deployment scenarios is the DCS-7280R4-64QC-10PE-F optimized for?
A: This switch is purpose-built for demanding environments including data center spine and leaf architectures, AI/ML cluster networking, high-performance storage networks, Content Delivery Networks, Service Provider peering and backbone, and Data Center Interconnect applications requiring high bandwidth and deterministic latency.

Q: Does this model support line-rate encryption?
A: Yes, with the K-series variant and appropriate EOS license, the platform supports TunnelSec line-rate encryption at all speeds from 25G to 800G using AES-256-GCM. Encryption options include MACsec, IPsec, and VXLANsec for comprehensive point-to-point and end-to-end data security without performance penalty.

Q: What makes the 7280R4 suitable for AI/ML workloads?
A: The 7280R4 delivers lossless forwarding through Virtual Output Queueing with 16GB deep buffers, eliminating head-of-line blocking and packet drops critical for AI/ML traffic patterns. High port density, ultra-low latency, and support for 800G interfaces enable efficient AI cluster connectivity and in-cast traffic management.

Q: Can this switch scale to internet routing table sizes?
A: Yes, the FlexRoute engine supports internet-scale routing with flexible forwarding profiles. The standard 7280R4 supports substantial routing tables, while the 7280R4K variant scales to over 5 million IP routes with fast convergence and low power consumption, suitable for Service Provider edge and peering applications.

Q: What operating system and management options are available?
A: The switch runs Arista EOS, a fully programmable Linux-based network operating system. Management options include CLI, web interface, RESTful eAPI, NETCONF, CloudVision for network-wide automation, Zero Touch Provisioning, advanced streaming telemetry, and comprehensive third-party integration through open APIs.
