Description

Arista DCS-7050QX-32S — 32x QSFP+ 40GbE + 4x SFP+ 1U Data Center Switch

Technical Identity

The Arista DCS-7050QX-32S (7050QX-32S) is a 1U data-center Ethernet switch from the Arista 7050X series with 32x QSFP+ 40GbE ports plus 4x SFP+ 10GbE ports, 2.56 Tbps of switching capacity and cut-through latency of approximately 550 ns per the Arista 7050QX datasheet. Condition: Refurbished.

Specifications

  • Brand: Arista Networks
  • Model / MPN: DCS-7050QX-32S
  • Product type: Data-center Ethernet switch (fixed configuration)
  • Product family: Arista 7050X Series
  • Ports: 32x QSFP+ 40GbE + 4x SFP+ 10GbE
  • Breakout: QSFP+ ports support 4x10GbE, up to 96x 10GbE + 8x 40GbE
  • Switching capacity: 2.56 Tbps
  • Latency: ~550 ns cut-through (datasheet range 550-650 ns)
  • Packet buffer: 12 MB shared, Dynamic Buffer Allocation (up to 6.7 MB to a single port)
  • Form factor: 1U rack-mount
  • Power: typically under 5 W per 40GbE 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 7050QX-32S extends the widely deployed 7050QX-32 design with four native SFP+ 10GbE ports, useful for uplinks, management-adjacent services or low-count 10GbE devices without consuming a QSFP+ breakout. It delivers wire-speed L2/L3 forwarding across all ports, with Dynamic Buffer Allocation drawing on the 12 MB shared packet memory during congestion. Arista EOS provides Zero Touch Provisioning and Linux-based tooling as documented in the 7050QX datasheet.

Use Cases

  • 40GbE leaf/spine and top-of-rack aggregation in data centers
  • High-density 10GbE server access via 4x10GbE breakout plus 4 native SFP+ ports
  • Lab, staging and test fabrics on the EOS 4.28-and-earlier trains
  • Spare or expansion unit for existing 7050QX estates

What This Is NOT

  • NOT the DCS-7050QX-32. The plain -32 has no SFP+ ports and an earlier software support cutoff.
  • NOT the DCS-7050QX2-32S. The QX2 is a different, later platform.
  • NOT a 100GbE switch. QSFP+ 40GbE only; QSFP28 100GbE operation is not supported.
  • 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: QSFP+ 40GbE transceivers, DAC and AOC; SFP+ 10GbE optics/DAC in the 4 SFP+ ports; 4x10GbE breakout on QSFP+ ports.
  • Typical peer platforms: 10/40GbE leaf-spine fabrics and 10GbE server NICs via breakout or SFP+.
  • 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 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-7050QX-32S?
The DCS-7050QX-32S is a 1U Arista 7050X-series data-center Ethernet switch with 32x QSFP+ 40GbE ports plus 4x SFP+ 10GbE ports, 2.56 Tbps of switching capacity, approximately 550 ns cut-through latency and a 12 MB dynamically shared packet buffer, running Arista EOS.

Q. How does the DCS-7050QX-32S differ from the DCS-7050QX-32?
The -32S adds 4 dedicated SFP+ 10GbE ports alongside the 32 QSFP+ ports and has a later software support timeline (supported through the EOS 4.28 train, versus EOS 4.24 for the plain 7050QX-32).

Q. Can the QSFP+ ports of the DCS-7050QX-32S break out to 10GbE?
Yes. Per the Arista 7050QX datasheet, QSFP+ ports can operate as 4x10GbE, allowing configurations up to 96x 10GbE plus 8x 40GbE in addition to the 4 native SFP+ ports.

Q. Does the DCS-7050QX-32S support 100GbE?
No. The QSFP+ ports are 40GbE; QSFP28 100GbE operation is not supported. For 100GbE, a 7060X-class platform such as the DCS-7060CX-32S is required.

Q. Which Arista EOS versions support the DCS-7050QX-32S?
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-7050QX-32S supplied in by T.E.S IT-SOLUTIONS?
Refurbished. The 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.
