Description

Arista DCS-7050SX2-72Q — 48x SFP+ 10GbE + 6x QSFP+ 40GbE 1U Data Center Switch

Technical Identity

The Arista DCS-7050SX2-72Q (7050SX2-72Q) is a 1U data-center Ethernet switch from the Arista 7050X2 series with 48x SFP+ 10GbE ports and 6x QSFP+ 40GbE ports, 1.44 Tbps of switching capacity and cut-through latency of approximately 550 ns. Stock labels for this listing include "DCS7050SX2-72" and "DCS-7050SX2-72Q". Condition: Refurbished.

Specifications

  • Brand: Arista Networks
  • Model / MPN: DCS-7050SX2-72Q
  • Product type: Data-center Ethernet switch (fixed configuration)
  • Product family: Arista 7050X2 Series
  • Ports: 48x SFP+ 10GbE + 6x QSFP+ 40GbE
  • Breakout: each QSFP+ port configurable as 4x10GbE (up to 72 logical 10GbE ports)
  • Switching capacity: 1.44 Tbps
  • Forwarding rate: ~1,080 Mpps
  • Latency: ~550 ns cut-through
  • Form factor: 1U rack-mount
  • Power: typically under 2 W per 10GbE port (datasheet)
  • Airflow / PSU: -F (front-to-rear) or -R (rear-to-front) variant per unit label — verify before order
  • Operating system: Arista EOS (supported through the EOS 4.28 release train)
  • Condition: Refurbished

Engineering Context

The 7050SX2-72Q is a classic 10GbE leaf/top-of-rack design: 48 SFP+ server-facing ports with 6 QSFP+ 40GbE uplinks toward the spine, at wire speed for L2 and L3. Arista EOS supplies the platform's automation, telemetry and Linux-based operational tooling as documented in the 7050X2 materials. The X2 generation succeeded the original 7050SX-72Q with an updated switch silicon and larger tables.

Use Cases

  • 10GbE server access / leaf switching with 40GbE spine uplinks
  • Up to 72 logical 10GbE ports via QSFP+ breakout for dense 10G aggregation
  • Lab, staging and test fabrics on EOS 4.28-and-earlier trains
  • Spare or expansion unit for existing 7050X2 estates

What This Is NOT

  • NOT the original DCS-7050SX-72Q. The SX2 is the later 7050X2-generation platform; support timelines differ.
  • NOT a 25GbE or 100GbE switch. SFP28 and QSFP28 operation are not supported; ports are 10GbE SFP+ and 40GbE QSFP+.
  • NOT an InfiniBand switch. Ethernet only.
  • NOT supported by current EOS trains. EOS 4.29 and later do not support this platform (last supported train: EOS 4.28).
  • NOT supplied with transceivers, cables, rail kits or other accessories unless explicitly stated.
  • NOT sold with any EOS software license or support entitlement. Software and support arrangements are between the buyer and Arista.

Compatibility & Hard Constraints

  • Optics/cabling: SFP+ 10GbE optics/DAC/AOC in the 48 access ports; QSFP+ 40GbE optics/DAC/AOC (or 4x10GbE breakout) in the 6 uplink ports.
  • Typical peer platforms: 10GbE server NICs at the access layer; 40GbE spine switches upstream.
  • Airflow: the -F / -R airflow variant must match your hot-aisle/cold-aisle design — confirm the variant on the unit label before ordering.
  • Software: supported up to the EOS 4.28 train; EOS image access requires an Arista account/entitlement.
  • Pre-deployment verification: confirm the exact model string, airflow direction, PSU type and EOS image availability against the unit label and Arista documentation.

Frequently Asked Questions (FAQ)

Q. What is the Arista DCS-7050SX2-72Q?
The DCS-7050SX2-72Q is a 1U Arista 7050X2-series data-center Ethernet switch with 48x SFP+ 10GbE ports and 6x QSFP+ 40GbE ports, 1.44 Tbps of switching capacity and cut-through latency of approximately 550 ns, running Arista EOS.

Q. Is a unit labeled DCS7050SX2-72 the same as the DCS-7050SX2-72Q?
Units in this listing carry label spellings including "DCS7050SX2-72" and "DCS-7050SX2-72Q"; the canonical Arista part number published here is DCS-7050SX2-72Q (48x SFP+ + 6x QSFP+). Confirm the full model string on the unit label before order if the exact sub-model matters for your deployment.

Q. Can the QSFP+ ports of the DCS-7050SX2-72Q break out to 10GbE?
Yes. Each of the 6 QSFP+ 40GbE ports can be configured as four independent 10GbE ports, giving up to 72 logical 10GbE ports (48 SFP+ + 24 breakout).

Q. Does the DCS-7050SX2-72Q support 25GbE or 100GbE?
No. Ports are SFP+ 10GbE and QSFP+ 40GbE; SFP28 25GbE and QSFP28 100GbE operation are not supported.

Q. Which Arista EOS versions support the DCS-7050SX2-72Q?
Per Arista's end-of-support notice for the 7050X/X2 series, EOS releases up to and including the 4.28 train support this platform; EOS 4.29 and later do not. Arista's extended bug-fix window for the 4.28 train ended March 20, 2025. EOS software access requires an arrangement with Arista - no software entitlement is included with this hardware.

Q. What condition is the DCS-7050SX2-72Q supplied in by T.E.S IT-SOLUTIONS?
Refurbished. Each unit is tested, inspected and professionally packed, shipping from EU stock with global B2B delivery. Airflow variant (-F front-to-rear or -R rear-to-front) and PSU configuration are per unit label - confirm before order.
