What is the switching capacity and port configuration of DCS-7050CX3-32S-R?

The Arista DCS-7050CX3-32S-R provides 6.4Tbps bi-directional throughput with 32x QSFP100 ports supporting 100GbE and breakout to 40/50/25/10GbE, plus 2x SFP+ ports. This enables up to 129x10GbE or 2x1GbE interfaces with 2Bpps forwarding capacity and 800ns latency.

How does the packet buffering work in this switch?

It features 32MB integrated intelligent buffer with dynamic allocation across all ports. This shared architecture intelligently manages microbursts and congestion, providing visibility into buffer usage per queue/port for precise tuning in high-scale data center environments.

What airflow and redundancy options are available?

Rear-to-front airflow configuration with 2x hot-swappable 1+1 redundant AC PSUs and 4x N+1 redundant hot-swap fans. Color-coded components and Smart System Upgrade enable hitless maintenance without downtime.

What routing and scale capabilities does it support?

Supports 288K MAC entries, 360K IPv4 routes, 168K IPv4 host routes, OSPF/BGP/IS-IS, and 128-way ECMP. VXLAN, EVPN, and MLAG enable scalable IP fabrics for cloud-scale networking with multi-chassis redundancy.

Is it suitable for high-density 100GbE spine deployments?

Yes, with 32x100GbE ports, <10W per port efficiency, and 6.4Tbps non-blocking throughput. Low latency and deep buffers make it ideal for spine roles in Clos networks handling massive east-west traffic.

What management and monitoring features are included?

eAPI, OpenFlow, sFlow, mirror-to-CPU, TCPDump integration, Advanced Event Management, and CLI scheduler. Linux-based tools and VM Tracer provide comprehensive visibility and automation for large-scale operations.

Product overview

The Arista DCS-7050CX3-32S-R is a compact 1RU fixed-configuration switch from the 7050X3 Series, optimized for modern data center environments. It features 32x QSFP100 ports supporting 100GbE natively or breakout to 40/50/25/10GbE, plus 2x SFP+ ports for management or low-speed connectivity, providing up to 6.4Tbps bi-directional throughput and 2Bpps forwarding. With 800ns low latency, 32MB dynamic packet buffer allocation, and support for 288K MAC entries, 360K IPv4 routes, and 128-way ECMP, it excels in high-scale leaf-spine architectures. Rear-to-front airflow ensures efficient cooling in dense racks, complemented by 2+1 redundant hot-swap PSUs and 4x N+1 fans. Advanced features include VXLAN, EVPN, OpenFlow, live patching, and Stateful Fault Repair for resilient operations. Power efficiency under 10W per 100GbE port reduces OPEX in cloud, HPC, and big data deployments, while Broadcom merchant silicon enables deep buffer monitoring and precise congestion management.
