Arista DCS-7280SR2A-48YC6-R | 7280R2 48-Port 25G Switch, AlgoMatch, 6x 100G QSFP28

Q: What is AlgoMatch technology in the DCS-7280SR2A-48YC6-R?
A: AlgoMatch is an Arista innovation that combines general-purpose memory with advanced software algorithms to provide efficient, scalable packet matching for access control, policy-based forwarding, and network telemetry. It delivers higher scale and performance than traditional TCAM-based solutions while being more cost and power efficient.

Q: What is the difference between the DCS-7280SR2A-48YC6-R and DCS-7280SR2-48YC6-R?
A: The DCS-7280SR2A-48YC6-R includes AlgoMatch technology for advanced packet matching and policy enforcement, while the DCS-7280SR2-48YC6-R does not. Both models have identical port configurations and performance but the 'A' variant provides enhanced flexibility for ACLs, flow matching, and telemetry at scale.

Q: What deployment scenarios is the DCS-7280SR2A-48YC6-R best suited for?
A: This switch is ideal for leaf-spine data center fabrics, high-frequency trading, cloud service provider networks, storage clusters, and latency-sensitive applications requiring 25G server connectivity with 100G uplinks. It supports VXLAN EVPN, MLAG, and ECMP routing for modern IP fabrics.

Q: Can I mix 10G, 25G, 40G, and 100G speeds on this switch?
A: Yes. The 48 SFP28 ports support 1/10/25G speeds (configurable in groups of four ports), and the 6 QSFP28 ports support 40G or 100G operation. You can also break out QSFP28 ports to 4x25G or 4x10G using appropriate breakout cables and optics.

Q: What airflow direction does the -R suffix indicate?
A: The -R suffix denotes rear-to-front (back-to-front) airflow, where air is drawn in from the fan side and exhausted through the port side. This is designed for data centers with hot-aisle containment where cold air is at the rear and hot exhaust is at the front. For front-to-rear airflow, choose the -F variant.
