FAQs

Q: What is AlgoMatch technology and how does it benefit this switch?
A: AlgoMatch is Arista's innovative technology that combines general-purpose memory with advanced software algorithms to deliver flexible and scalable solutions for access control, policy-based forwarding, and network telemetry. It provides higher scale packet matching with better performance and efficiency compared to traditional TCAM-only solutions, making it ideal for modern data center applications requiring precise traffic management.

Q: What interface breakout options are supported on the DCS-7280QRA-C36S-F?
A: The switch offers exceptional flexibility with multiple interface combinations: 12x100GbE, 36x40GbE, 24x50GbE, 48x25GbE, or up to 120x10GbE. This allows you to adapt the switch to various network architectures and migrate between speeds as your data center requirements evolve, providing a future-proof investment.

Q: Is this switch suitable for spine-leaf data center architectures?
A: Yes, the DCS-7280QRA-C36S-F is purpose-built for spine-leaf designs. It supports up to 128-way ECMP for traffic distribution, VXLAN bridging and routing, scalable routing tables for internet peering, and MLAG for cross-sectional bandwidth maximization. The high-density 40G/100G ports and ultra-low latency make it an excellent choice for both leaf and spine roles in modern data centers.

Q: What routing protocols and Layer 3 features are supported?
A: The switch supports comprehensive Layer 3 routing including OSPF, IS-IS, BGP, PIM, static routes, and bidirectional forwarding detection (BFD). With optional FLX licensing, it can scale to over 1 million IPv4 LPM routes and 928K IPv6 LPM routes, making it capable of handling internet peering and large-scale routing requirements.

Q: What is the difference between the -F and -R airflow variants?
A: The DCS-7280QRA-C36S-F features front-to-rear airflow (air flows from the port side to the fan side), while the -R variant has rear-to-front airflow. The -F model is typically used in hot-aisle/cold-aisle data center designs where cold air is drawn from the front and exhausted to the rear hot aisle. Choose the airflow direction that matches your data center cooling architecture.
