About the Arista 7050X4 25G/100G ToR Switch
The Arista 7050X4 25G/100G ToR Switch delivers 32 × 100GbE QSFP100 ports with flexible 4×25GbE breakout capability, scaling to 128 server-facing 25GbE connections per unit. This 1RU fixed-configuration design achieves a switching capacity of 6.4 Tbps and forwarding rate of up to 4.76 Bpps, making it ideal for network engineers and infrastructure teams building high-density, low-latency data center fabrics. The Arista DCS-7050CX4-32S combines enterprise-grade performance with operational simplicity, running Arista EOS for seamless integration into existing network automation workflows.
Built for demanding hyperscale and cloud environments, this top-of-rack switch features sub-microsecond cut-through forwarding and a 32 MB shared on-chip buffer to minimize packet loss under bursty traffic. Redundant, hot-swappable power supplies and fans—available in AC and DC configurations with front-to-rear and rear-to-front airflow options—ensure continuous operation across diverse data center layouts. Support for VXLAN tunnels via BGP EVPN control plane enables flexible overlay networking, while the MAC Address Table of 128,000 entries and dual routing engines (up to 128,000 host entries via LEM plus 65,536 IPv4 LPM routes and 32,768 IPv6 LPM routes) provide comprehensive scalability. IT procurement teams will appreciate the out-of-band 10/100/1000BASE-T management port and RJ45 console for reliable remote access. Operating across 0°C to 45°C, the Arista 7050X4 adapts to varied cooling strategies without compromise.

Frequently Asked Questions about Arista 7050X4 25G/100G ToR Switch
Does the Arista 7050X4 25G/100G ToR Switch support our SFP transceivers?
Most enterprise switches ship without transceivers; we quote vendor-matched optics alongside the switch (Cisco-genuine for Catalyst/Nexus, HPE/Aruba-genuine for CX, Juniper-genuine for QFX/EX). Third-party MSA-compatible options are also available at lower cost — specify preference in the RFQ.
Do you provide stacking / VPC / MLAG configuration help?
Yes — our network engineers can pre-stage stacking, VPC pairs, MLAG, EVPN-VXLAN, or fabric extender configurations in advance, or provide remote commissioning. Add commissioning to your RFQ.
What software licensing is included?
Switch software licensing varies by vendor. Cisco DNA / Cisco DCNM, Aruba CX licensing tiers, Juniper Premium, NVIDIA Cumulus — we quote the licensing tier matched to your features (BGP-EVPN, telemetry, automation). No surprises later.
Is the support global?
Yes — manufacturer hardware support is global (return-to-vendor or advance replacement depending on tier). For 24x7 same-day on-site replacement, attach a SmartNet / Foundation Care / J-Care contract during quoting.
