What is the port configuration and switching capacity of the DCS-7050TX2-128-R?

It features 96x triple-speed 100M/1G/10GBASE-T RJ45 ports and 8x QSFP+ 40GbE uplinks, delivering 2.56 Tbps full-duplex throughput and 1440 Mpps forwarding. This non-blocking architecture supports wire-speed across all ports for 10GbE access and 40GbE uplinks in leaf-spine designs.

Does it support advanced cloud networking features?

Yes, Arista EOS provides VXLAN bridging/routing, VM Tracer, OpenFlow 1.0+, eAPI, with 288K MAC entries, 144K IPv4 routes, and 208K host routes. Integrated packet capture via TCPDump and optional SSD enable stateful services directly on the switch.

What are the power and cooling specifications?

Dual hot-swappable 1+1 redundant AC PSUs with typical draw under 300W at 50% load, less than 5W per 10GbE port. Four N+1 redundant fans with reversible rear-to-front airflow ensure reliability in data center environments from 0-40°C.

How does the buffer design benefit deployments?

16MB enhanced shared buffer pool with dynamic allocation optimizes for incast scenarios in spine-leaf fabrics, preventing drops in VoIP, storage, and big data applications compared to 9MB in base 7050TX-128.

What management options are available?

CloudVision portal, 10/100/1000 mgmt port, RS-232 console, USB, SNMPv3, SSHv2, Syslog, IPv6 management, Linux tools, and Blue Beacon LED for easy identification in racks.

Is it suitable for high-frequency trading?

Yes, sub-microsecond port-to-port latency, precise EOS timestamping, and deep buffers support HFT with low jitter. Large table sizes handle extensive FIB and MAC learning in volatile market data feeds.
