Arista DCS-7050CX3-32C-DC-R | 7050X3 32-Port 100G Switch, DC Power, Rear Airflow

Q: What is the difference between the 32C and 32S variants?
A: The 32C variant ships standard with 16 GB DRAM and 32 GB flash storage, while the 32S includes 8 GB DRAM and 8 GB flash. The 32C also requires EOS 4.30.4 or higher, compared to 4.20.5 for the 32S, and is better suited for larger forwarding tables and advanced telemetry workloads.

Q: What deployment scenarios suit the DC-R variant?
A: The DC-R variant is purpose-built for environments with native -48VDC power plants, including telecom central offices, carrier points-of-presence, and colocation facilities. The dual 500W DC power supplies integrate directly with existing DC power distribution, eliminating external AC-to-DC conversion equipment.

Q: Can the QSFP100 ports be used for lower-speed connections?
A: Yes, each QSFP100 port supports flexible breakout configurations including 100GbE, 40GbE, 4x25GbE, 4x10GbE, or 2x50GbE, enabling seamless migration from legacy speeds and mixed-speed deployments across leaf and spine architectures.

Q: What is the rear-to-front airflow configuration?
A: Rear-to-front airflow means the switch draws cool air from the rear and exhausts hot air out the front. This reverse airflow is suitable for reverse hot-aisle/cold-aisle deployment patterns or installations where rear intake is required.

Q: Does this switch support network virtualization?
A: Yes, the DCS-7050CX3-32C-DC-R supports VXLAN and EVPN, NAT, and dynamic load balancing. It functions as both a VXLAN gateway and router, enabling efficient network virtualization, segmentation, and software-driven cloud networking architectures.
