Arista 7050SDX4-48D8 / SPX4-48D8 – 48× 100G Ports, 8× 400G QSFP-DD, Non-PoE, L2/L3/L4 Switching, 1U

Arista 7050X4 Series, including the DCS-7050SDX4-48D8 and DCS-7050SPX4-48D8, is a high-performance, 1RU switch family engineered for cloud-scale and data centre deployments. These models provide 48 × 100G ports with 8 × 400G QSFP-DD uplinks, delivering wire-speed performance with ultra-low latency and deterministic forwarding. Designed for modern spine-leaf architectures, high-performance computing clusters, and dense aggregation networks, the 7050X4 Series combines scalability, energy efficiency, and high availability.

With advanced Layer 2 and Layer 3 capabilities, including VLANs, VRF, inter-VLAN routing, and ECMP, the switches support seamless multi-tenant and multi-domain deployments. Flexible airflow options, hot-swappable redundant power supplies, and compact 1RU form factor enable deployment in both enterprise wiring closets and large-scale data centres. Integration with Arista EOS and CloudVision allows centralised automation, telemetry, and analytics, simplifying network management while ensuring high reliability and operational efficiency.

ADVANCED FEATURES:

Layer 2 & Layer 3 Switching:

The 7050X4 Series delivers full Layer 2 and Layer 3 switching capabilities, including VLANs, Private VLANs, Link Aggregation (LACP), VRF, and inter-VLAN routing. These features provide secure and flexible traffic segmentation, simplify multi-tenant deployments, and ensure efficient, deterministic forwarding across complex network topologies. Optimised for spine-leaf and aggregation architectures, the switches maintain high performance in dense data centre environments.

Layer 4 Support:

Comprehensive Layer 4 ACLs allow traffic filtering, prioritisation, and rate-limiting based on TCP/UDP ports, enabling granular control over application traffic such as HTTP, HTTPS, VoIP, DNS, and custom enterprise services. Layer 4 ACLs enhance security, traffic management, and QoS enforcement, ensuring latency-sensitive applications receive optimal network performance.

Virtualisation:

VXLAN and EVPN support enable scalable multi-tenant networks, allowing Layer 2 segments to extend seamlessly over Layer 3 infrastructure. This facilitates highly flexible and redundant cloud or virtualised deployments, supporting workload mobility, multi-site interconnectivity, and simplified network segmentation for enterprise and service provider environments.

High Availability:

Designed for mission-critical applications, the switches feature redundant, hot-swappable fans and power supplies, ensuring uninterrupted operation. Multi-Chassis Link Aggregation (MLAG) provides non-disruptive failover and seamless traffic continuity, maintaining maximum uptime and network reliability even during maintenance or component failure.

Quality of Service (QoS):

Each port supports eight hardware queues, enabling advanced traffic shaping, rate limiting, and priority queuing. This ensures consistent performance for latency-sensitive applications such as video conferencing, VoIP, real-time analytics, and high-performance computing, while providing fine-grained control per VLAN, port, or application type.

Telemetry & Analytics:

The switches support sFlow, LANZ for microburst detection, and streaming telemetry, providing real-time monitoring of network health and performance. Integration with Arista CloudVision enables centralised visibility, predictive analytics, and proactive congestion detection, empowering administrators to optimise resource allocation and troubleshoot potential network issues before they impact applications.

Automation & Programmability:

Supports Zero-Touch Provisioning (ZTP), eAPI, Python scripting, JSON, and OpenConfig, enabling automated configuration, policy enforcement, and rapid deployment. This allows scalable, error-free network operations, reduces operational overhead, and integrates seamlessly with DevOps or NetOps workflows for modern cloud and enterprise networks.

Security:

Comprehensive security features include ACLs at Layer 2, Layer 3, and Layer 4, 802.1X authentication, DHCP snooping, IP Source Guard, dynamic ARP inspection, and control plane protection. These mechanisms prevent unauthorised access, protect against rogue devices, and defend against malicious traffic, ensuring compliance with enterprise security policies and protecting mission-critical applications.

Energy Efficiency:

Optimised airflow design, intelligent fan control, and low power consumption reduce operational costs while maintaining high performance. These energy-efficient features are ideal for large-scale data centres, helping organisations meet sustainability goals without compromising throughput or reliability.

Future-Proof Architecture:

The 7050X4 Series is built on a high-performance, programmable architecture capable of adapting to evolving data centre demands. It supports emerging protocols and automation frameworks, making it a future-ready solution for scalable, cloud-ready networks.

Comprehensive Observability:

With integrated telemetry, event streaming, and support for advanced analytics, the switches provide deep visibility into traffic patterns, congestion events, and application performance, helping administrators make informed decisions and maintain optimal network health.
