Configuration at a Glance
Tailored per engagement. Full technical overview below.
Overview
The Arista 7050CX3-32S is a 1U fixed switch delivering 32 wire-speed 100GbE QSFP ports, configured and tested for top-of-rack leaf and small-spine roles in modern cloud fabrics. Each unit is sourced through authorized Arista channels, validated on the requested EOS release, and backed by manufacturer warranty before it leaves staging.
Who This Solution Is For
Business Benefits
Predictable low latency
Cut-through forwarding at roughly 800 nanoseconds keeps east-west application traffic consistently fast.
Rack-efficient density
Thirty-two 100G ports in a single rack unit consolidate cabling and free valuable rack space.
Unified EOS operations
A single EOS image across the fleet simplifies automation, telemetry, and lifecycle management.
Typical Business Use Cases
Top-of-rack leaf in 25/100G fabrics
Compact spine for smaller pods
100G server and storage aggregation
Legacy 10/40G access refresh
Industry Applications
Technical Overview
Built on the Arista 7050X3 architecture with a 6.4Tbps single-chip packet processor and a shared 32MB intelligent buffer, the 7050CX3-32S provides wire-speed L2/L3 forwarding across all 100G ports. Multi-speed QSFP100 ports break out to 4x25GbE or 4x10GbE, and the platform runs the same EOS and CloudVision tooling as the rest of the 7000 family.

Frequently Asked Questions
Is the 7050CX3-32S a good fit as a leaf in a 25/100G fabric?
Yes; its 32 multi-speed 100G ports break out to 25G for servers while reserving 100G uplinks to spine, making it a standard ToR leaf choice.
Does it run the same EOS as larger Arista switches?
It runs the identical Arista EOS image and CloudVision tooling used across the 7280R and 7800R lines, so automation and telemetry workflows carry over unchanged.
Can it serve as a small spine?
For compact pods it works well as a spine; for high-incast or lossless storage spines, the deep-buffer 7280R3 is the better-matched platform.
