The Arista DCS-7060CX-32S-F is a 1RU, 32-port 100G spine switch built on the first-generation 7060X platform. Delivering 6.4 Tbps of non-blocking switching capacity, 450 ns cut-through latency, and a 16 MB shared packet buffer, it is a proven spine-layer platform for high-density 25G/100G leaf-spine fabrics in cloud-scale data centers, financial trading infrastructure, HPC clusters, and large enterprise environments. The 7060CX-32S represents the foundation of Arista’s 32-port 100G spine portfolio — a mature, widely deployed platform with an established record in production data centers worldwide. The “-F” suffix denotes front-to-rear (forward) airflow, the standard configuration for traditional hot-aisle/cold-aisle data center designs where cold air is supplied from the front of the rack.
The 7060CX-32S is built on Broadcom’s Tomahawk ASIC (BCM56960), the silicon that established the 100G data center switching standard and powers a significant share of production spine deployments globally. This platform heritage matters: Broadcom Tomahawk silicon has been extensively production-validated across hyperscale, financial, and enterprise environments, with the full depth of EOS feature development concentrated on this architecture over years of active deployment. For architects choosing between the 7060CX-32S and the next-generation 7060CX2-32S: both platforms deliver identical 6.4 Tbps throughput and 450 ns latency. The 7060CX-32S offers a proven, cost-effective spine option for deployments where the CX2’s additional 22 MB buffer (vs 16 MB here) is not a deciding factor. The 7060CX is particularly well suited for fabrics where traffic patterns are predictable and congestion management needs are well-understood.
The DCS-7060CX-32S-F delivers 6.4 Tbps of full-duplex, non-blocking switching capacity across all 32 QSFP28 ports. Every port operates simultaneously at 100G line rate without oversubscription — the fundamental requirement for spine switches where east-west bandwidth is the primary architectural constraint. This throughput ceiling holds consistently regardless of traffic mix, packet size distribution, or active flow count, providing the predictable performance that production leaf-spine fabrics require.
In cut-through switching mode, the 7060CX-32S-F delivers 450 nanoseconds of port-to-port latency with consistent, low jitter across all 32 ports. This sub-microsecond performance makes it suitable for high-frequency trading platforms, real-time analytics pipelines, and distributed financial processing systems where spine-layer latency directly impacts application performance and round-trip times across the fabric.
The 7060CX-32S provides 32 × QSFP28 ports, each configurable at five different speeds:
The 16 MB shared buffer pool is dynamically allocated across all ports, concentrating available buffer depth on whichever ports experience congestion at any given moment — a more efficient approach than fixed per-port buffer allocation.
The DCS-7060CX-32S-F supports a broad ecosystem of standards-based optics and cables:
The 7060CX-32S-F is purpose-built for the spine layer of modern leaf-spine architectures:
The DCS-7060CX-32S-F includes Arista’s full telemetry stack:
Running on Arista EOS®, the DCS-7060CX-32S-F is built for automation-first network operations:
The “-F” airflow configuration provides front-to-rear (forward) cooling, where cool air enters from the non-port side of the switch and exhausts from the port side. This is the standard configuration for:
If your racks use rear-to-front (reverse) airflow, consider the DCS-7060CX-32S-R — identical in every respect except airflow direction.
The 7060CX-32S-F is built for long operational lifecycles with high MTBF ratings, field-replaceable fans and power supplies, and full EOS support. Its Broadcom Tomahawk ASIC is one of the most widely deployed and thoroughly tested data center switching platforms in the industry, providing operators confidence in long-term software support, vendor interoperability, and operational familiarity across large switch fleets.
Arista 7060 Series Switches: Architecture, Models, and Deployment Guide
The Arista DCS-7060CX-32S-F brings together 6.4 Tbps of non-blocking capacity, 450 ns cut-through latency, 32-port 100G density, and the proven Broadcom Tomahawk platform into a mature, production-validated 1RU spine switch. Its front-to-rear airflow makes it the standard choice for hot-aisle/cold-aisle data centers, and its full EOS feature set — from VXLAN/EVPN to LANZ telemetry and CloudVision automation — makes it ready to support any modern data center architecture. Available from BrightStar Systems fully tested, reset to factory defaults, and backed by a 1-year in-house warranty.
