Arista DCS-7050SX3-48YC8-F | 7050X3 48-Port 25G Switch, 8x 100G QSFP28, 4Tbps

Q: What port speeds does the DCS-7050SX3-48YC8-F support?
A: The 48 SFP28 ports support 1GbE, 10GbE, and 25GbE speeds, providing flexible migration from legacy 1G/10G infrastructure to modern 25G deployments. The 8 QSFP28 ports support 40GbE and 100GbE natively, and can also be broken out into 4x10G or 4x25G for additional flexibility.

Q: Is this switch suitable for spine-leaf data center architectures?
A: Yes, the DCS-7050SX3-48YC8-F is purpose-built for leaf-layer deployments in spine-leaf fabrics. It offers 48 high-density 25G server-facing ports and 8x 100G uplinks for spine connectivity, supporting VXLAN, EVPN, and up to 128-way ECMP routing for scalable, resilient data center networks.

Q: What is the difference between the -F and -R airflow models?
A: The -F suffix indicates front-to-rear airflow (intake from port side, exhaust from rear), ideal for hot-aisle/cold-aisle data center configurations. The -R model has rear-to-front airflow. Both offer identical port configurations and performance; choose based on your cooling design.

Q: Does this switch require licensing for advanced features?
A: The Arista 7050X3 series uses a tiered licensing model. Basic Layer 2/3 features are included. Advanced capabilities like full routing tables (up to 256K routes), EVPN, VXLAN, and MPLS require additional licenses such as FLX-Lite. Monitoring and automation features like ZTP, LANZ, and OpenFlow require a Monitoring & Automation license.

Q: Can this switch be deployed in high-frequency trading or low-latency environments?
A: Absolutely. With consistent 800-nanosecond latency and low jitter, the DCS-7050SX3-48YC8-F is engineered for latency-sensitive applications including financial trading, real-time analytics, HPC, and high-performance storage environments where every nanosecond matters.
