Product overview

The Arista DCS-7050SX-72-F is a purpose-built data center switch from the 7050X series, featuring 48 x 10 Gigabit Ethernet SFP+ ports and 2 x MXP connectors that provide flexible 6 x 40GbE or up to 24 x 10GbE uplink capacity in a compact 1RU form factor. With 1.28 Tbps switching capacity and 960 Mpps forwarding rate, it supports wire-speed L2/L3 performance with latency as low as 550 ns, making it ideal for leaf/spine architectures in cloud-scale environments. Equipped with quad-core x86 CPU, 8GB DRAM, 4GB flash, and 12MB shared packet buffer, the switch runs Arista EOS with advanced features including VXLAN overlay, EVPN, MLAG, and full routing suite (OSPF, BGP, IS-IS). Front-to-back airflow configuration includes 4x N+1 redundant FAN-7000-F modules and dual hot-swappable 500W AC power supplies (PWR-500AC-F). Management options include 1GbE RJ45, RS-232 serial, and USB ports. Designed for hyperscale data centers, high-performance computing, and enterprise IP fabric deployments, it supports 288K MAC addresses, 4K VLANs, and jumbo frames up to 9216 bytes. The deep buffer architecture handles microbursts effectively while maintaining predictable low latency for storage, virtualization, and analytics workloads.

Frequently asked questions

What uplink flexibility does the MXP provide?

Each MXP port supports 3x40GbE QSFP+ or 12x10GbE SFP+ breakout, providing 6x40GbE or 24x10GbE total uplink capacity from 2x MXP connectors. This allows field-upgradable bandwidth without hardware changes, supporting SR4/LR4 optics and DAC cables for spine connectivity.

What Layer 3 routing protocols are supported?

Full IPv4/IPv6 unicast and multicast routing suite including OSPF, BGP, IS-IS, RIP with VRF segmentation and 128-way ECMP. Hardware VXLAN routing with EVPN control plane enables overlay fabrics without performance penalty, ideal for multi-tenant cloud deployments.

What is the power consumption profile?

Typical consumption around 280W with dual 500W redundant PSUs providing headroom for full port utilization. Efficiency optimized for 10/40GbE densities with 80PLUS Platinum certified supplies and intelligent power management via EOS.

Does it support network virtualization?

Yes, hardware VXLAN gateway with 12MB deep buffer supports overlay networks up to 16K VTEPs. MLAG provides multi-chassis LAG redundancy while EVPN handles BUM traffic suppression and MAC mobility across fabric leaves.

What management interfaces are available?

Dedicated 1GbE RJ45 management, RS-232 console, and USB ports with EOS supporting CLI, REST API, gNMI telemetry, and ZTP. Event Manager provides real-time state streaming for operational visibility across thousands of switches.

What transceiver compatibility exists?

All MSA-compliant SFP+ (10GBASE-SR/LR/ER) and QSFP+ (40GBASE-SR4/LR4) transceivers plus Arista-compatible DAC/AOC cables. FlexOptics technology enables splitter cables for 40G-to-4x10G breakout directly in MXP ports.
