Description

The Arista DCS-7050SX3-48C8C-DC-F is a high-performance 1RU data center switch delivering 2.56 Tbps throughput with 48x 10GbE SFP+ and 8x 100GbE QSFP100 ports. Designed for leaf-spine architectures and top-of-rack deployments, it features ultra-low latency from 800 nanoseconds, wire-speed Layer 2 and Layer 3 forwarding, and a fully shared 32MB packet buffer. The DC power configuration with front-to-rear airflow is ideal for enterprise data centers requiring reliable redundancy and consistent cooling.

Features

Wire-speed Layer 2 and Layer 3 forwarding with no oversubscription
- Unified Forwarding Table (UFT) for flexible MAC, IPv4, and IPv6 scaling
- VXLAN gateway and routing for network virtualization and overlay networks
- Comprehensive Layer 2 protocols: VLANs, Spanning Tree (MSTP, RSTP, RPVST+), LAG, MLAG
- Advanced Layer 3 routing: OSPF, IS-IS, BGP, RIP-2, multicast (PIM, IGMP)
- Low latency architecture: as low as 800 nanoseconds for latency-sensitive applications
- 32MB fully shared packet buffer for superior burst absorption
- Arista EOS operating system with stateful fault repair and modular architecture
- Zero Touch Provisioning (ZTP) for automated deployment
- LANZ (Latency Analyzer) for microburst detection and network visibility
- DANZ (Data Analyzer) advanced mirroring for comprehensive traffic monitoring
- sFlow for network telemetry and traffic analysis
- Programmable automation: eAPI, OpenConfig, EOS SDK, Python, Linux shell access
- CloudVision integration for centralized network management and analytics
- Hot-swappable dual redundant DC power supplies for maximum uptime
- MACsec ready hardware for secure Layer 2 encryption (with appropriate licensing)
- Traffic-aware ECMP and UCMP for intelligent load balancing

FAQs

Q: What is the difference between the 48C8C and 48C8 models?
A: The 48C8C variant features enhanced memory and flash storage compared to the standard 48C8 model, providing greater capacity for advanced routing tables and configurations while maintaining identical port configurations and performance.

Q: Can this switch be used in both leaf and spine roles?
A: Yes, the DCS-7050SX3-48C8C-DC-F is designed for flexible deployment as either a top-of-rack leaf switch with 10G server connections and 100G uplinks, or as a fixed configuration spine switch in smaller data center fabrics.

Q: What licensing is required for advanced features?
A: The switch includes base Layer 2 and Layer 3 features. Advanced capabilities like full routing (up to 256K routes), EVPN, VXLAN, and segment routing require the FLX-Lite license. Monitoring and automation features (ZTP, LANZ, TapAgg, API) require the appropriate software license.

Q: Is VXLAN gateway functionality supported?
A: Yes, the 7050SX3 series supports VXLAN gateway and routing capabilities through Arista EOS, enabling network virtualization and overlay networks for modern data center architectures.

Q: What is the difference between -F and -R airflow options?
A: The -F suffix indicates front-to-rear airflow (cold air intake at front, hot exhaust at rear), while -R models feature rear-to-front airflow. Choose based on your data center hot/cold aisle cooling design for optimal thermal management.
