What latency and buffering does the Arista DCS-7050TX-72Q-R provide?

Ultra-low cut-through latency of 3 microseconds at 10GbE speeds. Includes 12MB shared dynamic buffer allocation optimized for microburst absorption, ensuring no drops in bursty east-west traffic patterns common in virtualized data centers.

Which routing protocols and scale does EOS support on this switch?

Arista EOS enables BGP, OSPF, IS-IS, MP-BGP with 144K IPv4 routes, 288K MAC entries, and 208K IPv4 host routes. Supports up to 64-port LAGs and VXLAN for EVPN fabrics, scaling to large leaf-spine deployments.

What power and cooling options are available?

Dual hot-swappable AC PSUs (1+1 redundant, typical 570W/max 740W). Four N+1 redundant hot-swap fans with rear-to-front airflow (DCS-7050TX-72Q-R variant). Reversible airflow options and tool-less rails simplify rack installation.

Is it suitable for cloud and HPC use cases?

Yes, purpose-built for cloud with VXLAN, VM Tracer, OpenFlow; HPC benefits from low latency, deep buffers, 1.44Tbps throughput. Runs user apps in VM on x86 CPU with 8GB DRAM/optional 120GB SSD for logging.

What management and reliability features does it offer?

EOS includes AEM event management, live patching, Stateful Fault Repair (SFR), SSU/ASU upgrades without downtime. Integrated TCPDump, sFlow, USB restore, Blue Beacon LED for easy identification in racks.

Product overview

The Arista DCS-7050TX-72Q-R is a high-performance 1RU data center switch from the 7050X Series, purpose-built for cloud networking with 48 ports of 1/10GBASE-T copper connectivity and 6x 40GbE QSFP+ uplinks. It provides 1.44Tbps full-duplex switching capacity and 1080Mpps forwarding rate, ensuring wire-speed L2/L3 performance with ultra-low latency of 3 microseconds. Equipped with 12MB dynamic packet buffer allocation, it handles microbursts effectively in high-density environments. Powered by Arista EOS, the Extensible Operating System, it supports advanced features like VXLAN, VM Tracer, 288K MAC entries, 144K IPv4 routes, BGP/OSPF/IS-IS routing, OpenFlow, and up to 64-port LAGs. Redundant hot-swappable PSUs and N+1 fans with reversible rear-to-front airflow ensure high availability. Resilient x86 CPU with 8GB DRAM, 4GB flash, and optional SSD enable stateful fault repair, live patching, and Linux tools integration. Ideal for top-of-rack leaf, spine aggregation, and enterprise core deployments requiring scalable, low-latency 10/40GbE fabrics.

1.44Tbps full-duplex switching capacity supports dense 10/40G fabrics.
48x10GBASE-T + 6x40GbE QSFP+ ports enable high-density copper uplinks.
1080Mpps forwarding rate with 3μs low latency for wire-speed L2/L3.
12MB dynamic buffer allocation absorbs microbursts in cloud traffic.
Arista EOS provides VXLAN, BGP, automation for cloud-scale networks.
Redundant hot-swap PSUs/fans with rear-to-front airflow ensure 99.99% uptime.
