FAQs

Q: What is the difference between the DCS-7060X6-64PE-B-F and DCS-7060X6-64PE-F models?
A: The B revision designates an enhanced variant with improved port breakout capabilities, offering up to 512 x 100G or 512 x 50G breakout compared to 320 ports in the standard F model. Both feature front-to-rear airflow and identical switching capacity of 51.2 Tbps. The B-F model is optimized for deployments requiring maximum flexibility in port density and speed configurations.

Q: Is this switch suitable for AI/ML and GPU cluster deployments?
A: Yes, the DCS-7060X6-64PE-B-F is purpose-built for AI/ML workloads. It features a 165 MB shared packet buffer with Dynamic Buffer Allocation for burst absorption, Advanced DCQCN for lossless Ethernet under congestion, packet spraying for load-aware traffic steering, and 700 ns ultra-low latency to maximize GPU cluster efficiency. The 51.2 Tbps throughput supports high-density back-end AI cluster interconnects and storage networks.

Q: What is the benefit of the removable supervisor card architecture?
A: The field-replaceable supervisor card (DCS-7001-SUP-A) allows hardware upgrades and repairs without replacing the entire chassis, reducing capital expenditure and extending the platform lifecycle. This modular design lowers total cost of ownership and minimizes downtime for maintenance, as the supervisor can be accessed by removing the two right-most fan units.

Q: What optics and cables are compatible with the 800G OSFP ports?
A: The DCS-7060X6-64PE-B-F supports industry-standard 800GBASE-SR8, DR8, XDR, FR8 optics, proprietary 800G OSFP DAC and AOC cables, and is Linear Pluggable Optics (LPO) ready for future compatibility. It also supports flexible breakout configurations to 400G, 200G, 100G, and 50G speeds via appropriate breakout cables and optics. A full compatibility list is available at arista.com/transceivers-cables.

Q: Does the DCS-7060X6-64PE-B-F require additional software licenses?
A: The Arista 7060X6 series runs Arista EOS software. License requirements depend on the features and subscription services required for your deployment, such as CloudVision integration, advanced Layer 3 features, and support contracts. Contact an authorized Arista partner or distributor for detailed licensing information specific to your use case.
