Description

The Arista DCS-7050QX-32S-F is a high-density data center switch featuring 32 QSFP+ ports supporting 40GbE and 4 SFP+ ports for 10GbE connectivity in a compact 1RU form factor. Delivering 2.56 Tbps switching capacity with ultra-low latency as low as 550 nanoseconds, it is purpose-built for modern leaf-spine architectures in cloud, virtualization, and high-performance computing environments. Front-to-rear airflow design and dual hot-swappable 500W AC power supplies ensure reliable operation in demanding data center deployments.

FAQs

Q: What is the difference between the DCS-7050QX-32 and DCS-7050QX-32S?
A: The DCS-7050QX-32S includes 4 additional SFP+ 10GbE ports that are shared with the first QSFP+ port, allowing direct connection of 10GbE and 1GbE interfaces. The DCS-7050QX-32 has only the 32 QSFP+ ports without the additional SFP+ ports.

Q: Can this switch be used in a leaf-spine architecture?
A: Yes, the DCS-7050QX-32S-F is specifically designed for modern leaf-spine data center architectures. It supports 64-way ECMP and 64-way MLAG for scalable designs that efficiently balance traffic across large-scale two-tier deployments.

Q: Does this model require additional licenses for Layer 3 features?
A: Advanced Layer 3 routing protocols such as BGP, OSPF, ISIS, PIM, and NAT require the optional Enhanced L3 License (LIC-FIX-2-E). Virtualization features like VXLAN and VM Tracer require the Virtualization License (LIC-FIX-2-V). Basic Layer 2 and Layer 3 features are included.

Q: What airflow direction does the F model have?
A: The F model designation indicates front-to-rear airflow, meaning air is drawn in from the front of the chassis and exhausted out the rear. This is standard for most data center hot-aisle/cold-aisle deployments.

Q: Can QSFP+ ports be broken out to 10GbE?
A: Yes, up to 24 QSFP+ ports can be configured as 4x10GbE each using breakout cables, providing up to 96x10GbE plus 8x40GbE connectivity. This offers deployment flexibility for mixed 10G and 40G environments.
