Arista DCS-7050SDX4-48D8-R | 7050X4 48-Port 100G Switch, 8x 400G QSFP-DD, 8Tbps

Q: What port speeds does the DCS-7050SDX4-48D8-R support?
A: Each 100GbE SFP-DD port supports 100G, 50G, 25G, and 10G speeds with flexible configuration. Each 400GbE QSFP-DD port supports 400G, 200G, 100G, and 40G speeds with breakout capability up to 72 logical ports.

Q: What is the airflow direction for this switch?
A: The DCS-7050SDX4-48D8-R features rear-to-front airflow, meaning air intake is on the port side and exhaust is on the fan side. This is indicated by the -R suffix in the model number.

Q: Is this switch suitable for leaf and spine architectures?
A: Yes, the 7050SDX4-48D8 is optimized for both top-of-rack leaf and fixed-configuration spine deployments in modern data center networks, supporting large-scale leaf-spine topologies with ECMP and MLAG.

Q: What is the packet buffer size and why does it matter?
A: The switch features a 132MB fully shared packet buffer with dynamic allocation, providing superior burst absorption and managing microburst traffic effectively. This reduces packet loss during congestion compared to fixed per-port buffer architectures.

Q: Does this switch require licensing for Layer 3 features?
A: Arista switches run Arista EOS software which provides comprehensive Layer 2 and Layer 3 features. Check with your Arista representative or authorized reseller for current licensing requirements and subscription models for advanced features.
