Arista DCS-7135V-48Y-4QC-R | 7135V 48-Port 25G SFP28 Switch, 4x 100G QSFP28, FPGA

Q: What is the primary use case for the Arista DCS-7135V-48Y-4QC-R?
A: This switch is designed for ultra-low latency applications such as high-frequency trading, financial services, and data center environments requiring programmable FPGA functionality. It provides Layer 1+ switching with nanosecond-level latency and supports custom application development on the integrated Xilinx FPGA.

Q: What does the FPGA enable on this switch?
A: The Xilinx UltraScale+ FPGA enables programmable network functions including dynamic patching, tapping, packet replication, media conversion, precise timestamping, and custom application development. Organizations can deploy Arista applications or develop their own using Arista's FPGA development kits.

Q: Does the DCS-7135V-48Y-4QC-R support both Layer 1 and Layer 2/3 features?
A: Yes, the 7135V series combines Layer 1+ cross-point switching with full Arista EOS capabilities, providing advanced Layer 2 and Layer 3 features alongside ultra-low latency Layer 1 functionality. This makes it suitable for both traditional switching and specialized low-latency applications.

Q: What optics are supported on this switch?
A: The SFP28 ports support 25G and 10G SFP transceivers, while the QSFP28 ports support 100G, 40G, 4x25G, and 4x10G optics and DAC cables. Arista's Enhanced Performance (E-Series) optics enable operation without FEC for even lower latency.

Q: Can this switch be managed with Arista CloudVision?
A: Yes, the DCS-7135V-48Y-4QC-R runs Arista EOS and integrates natively with CloudVision for centralized network management, streaming telemetry, automation, and workflow orchestration across your entire data center fabric.
