Description

The Arista DCS-7050SX3-48YC8-R is a high-performance 1RU data center switch delivering 48 ports of 1/10/25GbE SFP28 and 8 ports of 40/100GbE QSFP28 with 4 Tbps switching capacity. Engineered for low-latency leaf-spine architectures, it features 800ns cut-through latency, 32MB packet buffer, and wire-speed Layer 2/3 forwarding. Running Arista EOS, it supports VXLAN, EVPN, advanced automation, and streaming telemetry for modern cloud, HPC, and enterprise data center deployments.

Features

Wire-speed Layer 2 and Layer 3 switching with hardware-based forwarding
- VXLAN routing and bridging with EVPN control plane for network virtualization
- Advanced BGP, OSPF, IS-IS routing with 128-way ECMP load balancing
- Comprehensive Layer 2 features: VLANs, STP/RSTP/MSTP, LAG/MLAG
- Multi-chassis LAG (MLAG) for active-active redundancy
- IEEE 1588 PTP (Precision Time Protocol) for sub-microsecond timing accuracy
- Low-latency architecture (800ns) optimized for HPC and financial trading applications
- Intelligent shared packet buffer (32MB) for burst absorption and QoS
- sFlow, NetFlow, and streaming telemetry for real-time network visibility
- Latency Analyzer (LANZ) for microburst and congestion detection
- Tap aggregation and advanced mirroring capabilities
- ACLs, MACsec-ready hardware, and control plane security features
- Hot-swappable redundant power supplies and fan modules
- Stateful Fault Repair (SFR) for software self-healing
- Native Linux-based EOS with on-box Python/Bash scripting
- CloudVision integration for centralized provisioning and change management
- OpenConfig/YANG models and gRPC for model-driven network management

FAQs

Q: What port speeds are supported on the SFP28 and QSFP28 ports?
A: The 48 SFP28 ports support 1GbE, 10GbE, and 25GbE speeds independently on each port. The 8 QSFP28 ports support 40GbE and 100GbE speeds, and can also be configured for breakout options including 4x25GbE, 4x10GbE, or 2x50GbE for flexible network topology design.

Q: What is the airflow direction on the DCS-7050SX3-48YC8-R model?
A: The 'R' suffix indicates rear-to-front (back-to-front) airflow, designed to align with hot-aisle/cold-aisle data center cooling strategies where air is drawn in from the rear and exhausted at the front of the switch.

Q: What software features does Arista EOS provide for automation?
A: Arista EOS supports comprehensive automation including Zero Touch Provisioning (ZTP), native Python and Bash scripting, JSON-RPC eAPI for integration with Ansible and Terraform, CloudVision for centralized management and telemetry, LANZ for microburst detection, streaming telemetry via OpenConfig/gRPC, and sFlow for traffic visibility.

Q: Is this switch suitable for leaf-spine data center architectures?
A: Yes, the DCS-7050SX3-48YC8-R is optimized for leaf-spine deployments with 48 high-speed server-facing ports and 8 uplink ports providing flexible connectivity to spine switches. Its low 800ns latency, non-blocking architecture, and support for VXLAN/EVPN overlays make it ideal for modern cloud and enterprise data center fabrics.

Q: What licensing is required for advanced routing features?
A: The switch requires appropriate Arista software licenses for advanced features. A FlexRoute (FLX) license enables full routing capabilities including up to 256K routes, EVPN, VXLAN routing, segment routing, and base MPLS LSR functions. Base automation features like ZTP, LANZ, and API access are included with standard licensing.
