Arista 7050X4 Series 100/400G Top-of-Rack Switch

The Arista 7050X4 Series, represented by the DCS-7050DX4-32S-F, is a high-density 100G/400G top-of-rack switch built on a single-chip architecture that delivers 12.8 Tbps of aggregate switching capacity. Designed for modern enterprise and cloud data center environments, the platform provides 32 x 400GbE QSFP-DD ports that can be broken out to support 100GbE and 25GbE downstream server connectivity, enabling flexible spine-leaf deployments without forklift upgrades as bandwidth demands grow. The switch runs Arista EOS (Extensible Operating System), which provides a consistent, programmable network operating environment with rich support for BGP EVPN, VXLAN, and segment routing overlays.

The DCS-7050DX4-32S-F utilizes a front-to-rear airflow design suited for standard data center hot-aisle/cold-aisle containment architectures. The platform supports Arista's AVA (Arista Virtual Assist) and CloudVision integration, enabling centralized telemetry, streaming analytics, and intent-based provisioning across large-scale fabric deployments. Hardware-based telemetry with nanosecond-resolution timestamping supports precise network visibility for congestion management and rapid fault isolation, which is critical in latency-sensitive workloads such as financial trading, AI/ML training clusters, and high-performance storage fabrics.

As a purpose-built 400G top-of-rack switch, the 7050X4 series occupies a single rack unit, conserving valuable data center floor space while delivering the port density required for leaf-layer connectivity in spine-leaf architectures. Support for advanced buffer management, rich Quality of Service capabilities, and standards-based protocols such as PFC and ECN makes the platform well-suited to converged Ethernet fabrics carrying both IP storage and server traffic. Native integration with Arista's zero-trust network security framework and macro-segmentation capabilities allows enterprises to apply consistent policy enforcement at the access edge of the data center fabric.

Ideal for

• Leaf switching node in BGP EVPN/VXLAN spine-leaf data center fabric deployments
• High-density 100G server access layer for AI and ML compute clusters requiring low-latency east-west traffic paths
• Top-of-rack aggregation for NVMe-oF and iSCSI all-flash storage arrays demanding lossless Ethernet with PFC and ECN
• Network edge upgrade path for enterprises migrating from 10G/25G server infrastructure to 100G without replacing spine hardware
• Consolidated data center interconnect breakout switch supporting mixed 400G uplinks and 100G/25G downlink server ports within a single 1U platform
• Telemetry collection point in streaming analytics pipelines leveraging Arista CloudVision for real-time network observability and automated remediation
