FAQs

Q: What is the difference between DCS-7050QX2-32S-R and DCS-7050QX-32S-R?
A: The DCS-7050QX2-32S-R is the second-generation model (7050X2) with enhanced performance and features compared to the original 7050QX-32S-R (7050X). Both offer similar port configurations but the QX2 version provides improved throughput and reliability for demanding data center environments.

Q: Can the QSFP+ ports be broken out into 10GbE ports?
A: Yes, up to 24 QSFP+ ports can be used as 4x10GbE breakout ports, providing up to 96x10GbE and 8x40GbE configuration flexibility. The 4 SFP+ ports are shared with the first QSFP+ port for direct 10GbE and 1GbE connectivity.

Q: What does the 'R' suffix indicate in the model number?
A: The 'R' suffix indicates rear-to-front (back-to-front) airflow design, which is suitable for cold aisle rack configurations. The alternative 'F' model provides front-to-rear airflow for hot aisle deployments.

Q: Is this switch suitable for leaf-spine network architectures?
A: Yes, the DCS-7050QX2-32S-R is purpose-built for modern leaf-spine data center architectures, supporting east-west traffic patterns with wire-speed Layer 2 and Layer 3 forwarding, low latency, and flexible 10G/40G port configurations.

Q: What software features are supported on this switch?
A: The switch runs Arista EOS (Extensible Operating System) with support for advanced Layer 2/3 routing protocols (BGP, OSPF, ISIS), VXLAN, VM Tracer, zero-touch provisioning (ZTP), LANZ (Latency Analyzer), OpenFlow, and comprehensive network automation via APIs.
