FAQs

Q: What is the maximum number of 25G ports this switch supports?
A: The DCS-7050SX3-96YC8-R provides 96x 25GbE SFP28 ports. Each SFP28 port can be configured in groups of 4 to run at 25G, 10G, or 1G speeds, providing flexible connectivity options for mixed-speed environments.

Q: Can the QSFP100 ports be used for lower-speed connections?
A: Yes, each of the 8x QSFP100 ports supports 100GbE and 40GbE natively, and can be broken out to 4x25GbE or 4x10GbE using appropriate breakout cables and transceivers, providing deployment flexibility.

Q: What are the key use cases for this switch?
A: The DCS-7050SX3-96YC8-R is ideal for high-density 25GbE server access in leaf-spine architectures, cloud data centers, high-performance computing environments, and storage fabrics requiring ultra-low latency and high throughput.

Q: What software features does Arista EOS provide on this platform?
A: Arista EOS delivers wire-speed Layer 2 and Layer 3 forwarding, VXLAN routing and bridging, EVPN, 128-way ECMP, 64-way MLAG, hardware-based NAT, advanced telemetry, sFlow, LANZ for microburst detection, and comprehensive automation via Zero Touch Provisioning and CloudVision integration.

Q: What airflow direction does the -R model designation indicate?
A: The -R suffix indicates rear-to-front (back-to-front) airflow, where cool air is drawn in from the rear and exhausted out the front. This is suitable for data centers with hot-aisle/cold-aisle configurations where switch backs face the cold aisle.
