What is the port configuration and throughput of DCS-7260CX-64-R?

The Arista DCS-7260CX-64-R features 64x QSFP100 ports supporting 100GbE/40GbE and breakout to 10/25GbE, plus 2x SFP+ ports, delivering 12.8Tbps full-duplex non-blocking throughput with 258 max 10GbE ports. This supports wire-speed across all ports for high-density data center applications.

What latency and buffering does the 7260CX-64 provide?

Latency ranges from 500ns to 1500ns with 64MB shared dynamic buffer allocation per port group, enabling effective handling of microbursts and congestion in spine/leaf fabrics without packet loss in oversubscribed environments.

What advanced networking features are supported?

Includes VXLAN for overlays, MLAG up to 64x100GbE links, 128K IPv4 routes with 128 ECMP, OSPF/BGP/IS-IS routing, IGMP snooping, and 802.3x flow control with jumbo frames up to 9216 bytes for scalable L2/L3 deployments.

How is high availability ensured in DCS-7260CX-64-R?

1+1 redundant hot-swappable AC power supplies, N+1 hot-swap fans, rear-to-front cooling, Stateful Fault Repair (SFR), live patching, and Smart System Upgrade (SSU) provide carrier-grade reliability with minimal downtime.

What management options are available?

EOS supports CloudVision portal, eAPI/RESTCONF, SNMPv3, Syslog, ZTP zero-touch provisioning, LANZ microburst detection, TCPDump packet capture, and Linux bash access with RPM support for custom extensibility.

Is it suitable for hyperscale spine deployments?

Yes, with 136K MAC entries, 128K IPv4 routes, 104K host routes, high-scale MLAG/VXLAN, and 42MB+ buffers in related models, it excels in large-scale IP fabrics for cloud providers needing density and low latency.

Product overview

The Arista DCS-7260CX-64-R is a high-performance 7260X Series data center switch designed for demanding cloud and enterprise networking environments. Featuring 64x QSFP100 ports supporting 100GbE, 40GbE breakout to 10/25GbE, and 2x SFP+ ports, it provides 12.8Tbps full-duplex switching capacity with 258x max 10GbE ports via breakout. Latency ranges from 500-1500ns, supported by 64MB dynamic buffer allocation for congestion management in high-scale deployments. Equipped with dual high-performance x86 CPUs, 8GB DRAM, and Extensible OS (EOS), it enables advanced features like VXLAN overlay, MLAG for multi-chassis link aggregation up to 64x100GbE, 128K IPv4 routes, and 136K MAC entries. Redundant 1+1 hot-swappable AC power supplies and N+1 fans ensure high availability, with rear-to-front airflow optimizing rack cooling. Ideal for spine-layer aggregation in leaf-spine fabrics, hyperscale cloud networking, and HPC clusters requiring wire-speed forwarding, low latency, and resilient control plane with Stateful Fault Repair (SFR) and Smart System Upgrade (SSU). Management via CloudVision, eAPI, and Linux tools supports zero-touch provisioning (ZTP) and real-time monitoring with LANZ.
