Q: What is the airflow direction of the DCS-7020R4-48TX-4QC-R?
A: This model features rear-to-front airflow, meaning air flows from the fan side to the port side. This is ideal for hot aisle/cold aisle data center configurations where rear exhaust is required.

Q: What deployment scenarios is the 7020R4 Series best suited for?
A: The 7020R4 Series is purpose-built for data center leaf-spine architectures, service provider edge and peering applications, high-performance campus edge, and environments requiring advanced routing such as MPLS, Segment Routing, and EVPN-VXLAN overlays.

Q: Does this switch support advanced security features?
A: Yes, the 7020R4 supports wire-speed MACsec encryption at Layer 2 and Layer 3, VPN services including L2/L3 EVPN and VPLS, and optional TunnelSec encryption. It also supports advanced access control lists and traffic filtering.

Q: What is the benefit of the Virtual Output Queueing architecture?
A: The deep buffer VOQ architecture eliminates head-of-line blocking and virtually eliminates packet drops even under heavy congestion, making the switch ideal for Big Data, media streaming, and high-performance storage workloads with mixed traffic patterns.

Q: Is this switch compatible with Arista CloudVision?
A: Yes, the DCS-7020R4-48TX-4QC-R is fully compatible with Arista CloudVision for network-wide orchestration, automation, telemetry, and zero-touch provisioning, enabling simplified operations and proactive network monitoring.
