Arista DCS-7260CX3-64-R | 7260X3 64-Port 100G Switch, 12.8 Tbps, 2x 10G SFP+

Q: What deployment scenarios is the DCS-7260CX3-64-R best suited for?
A: The DCS-7260CX3-64-R is ideal for data center leaf-spine architectures, high-density server connectivity, cloud infrastructure aggregation layers, and high-performance computing clusters. It excels in environments requiring massive east-west traffic capacity and predictable low latency for VM migration, storage replication, and financial trading systems.

Q: Can the QSFP28 ports support multiple speed options?
A: Yes, each QSFP28 port supports flexible speed combinations including 100GbE, 50GbE, 40GbE, 25GbE, and 10GbE, allowing mixed-speed deployments on the same switch. This enables heterogeneous network architectures where different server generations or storage systems operate at different speeds without port restrictions.

Q: What is the difference between the -R and -F suffix models?
A: The suffix indicates airflow direction. The DCS-7260CX3-64-R features rear-to-front (back-to-front) airflow, while the -F model has front-to-rear airflow. Choose based on your data center hot aisle/cold aisle configuration to ensure proper cooling efficiency and alignment with your rack airflow design.

Q: Does this switch support advanced data center features?
A: Yes, the switch supports VXLAN for network virtualization, comprehensive Layer 2 and Layer 3 routing protocols including OSPF, BGP, IS-IS, and RIPv2, plus advanced QoS, multicast load balancing, and SDN features including OpenFlow and DirectFlow integration with Arista CloudVision management platform.

Q: What redundancy features are included?
A: The switch includes 1+1 redundant hot-swappable power supplies and N+1 hot-swappable fan modules, allowing maintenance without downtime. Arista EOS provides additional software redundancy through live patching, stateful fault repair, and smart system upgrades for zero-downtime operations.
