Arista 7020R Series Switches

Arista 7020R Series Switches (Used & Refurbished)
The Arista 7020R Series delivers deep-buffered, fixed-configuration switching for demanding 1GbE and 10GbE edge, storage, and content delivery environments. BrightStar Systems supplies fully tested, used and refurbished 7020R switches backed by our 1-Year In-House Warranty, helping you expand or refresh your network at a fraction of new hardware cost.

With flexible 1G/10G access, high-speed uplinks, and Arista EOS, the 7020R family is ideal for IP storage, media workflows, and data center or campus edge roles that require consistent performance under bursty traffic.
Arista 7020R Series Overview
The 7020R Series combines deep packet buffers, Virtual Output Queues (VOQ), and non-blocking Layer 2/Layer 3 switching in a compact 1RU form factor. These platforms are designed to handle microbursts and high fan-in traffic patterns typical of storage and content workloads, while maintaining predictable latency and low packet loss.

Key features of the Arista 7020R Series include:

Deep-buffered architecture for lossless operation under congestion
1GbE copper and 1/10GbE SFP+ access options with high-speed uplinks
Non-blocking Layer 2/Layer 3 forwarding with rich routing and IPv6 support
Arista EOS for automation, programmability, and telemetry
Compact 1RU form factors with redundant power supplies and fan modules

If you’re building a broader Arista 7000 Series fabric, the 7020R is often paired with higher-density 7050X Series or 7060X Series switches for leaf-spine or aggregation roles.

FAQ – Arista 7020R Series
Q: What makes the 7020R a deep-buffered switch?
The 7020R Series uses large shared buffers and Virtual Output Queues (VOQ) to absorb microbursts and high fan-in traffic patterns, reducing packet drops in storage and media workloads.

Q: Is the 7020R a good fit for IP storage networks?
Yes. Many customers deploy 7020R switches specifically at the storage or backup layer because the deep buffers help maintain throughput and reliability during heavy replication and backup windows.

Q: How does Arista EOS benefit 7020R deployments?
EOS provides a consistent, programmable operating system across Arista switches, with features like MLAG, advanced routing, automation APIs, and streaming telemetry that simplify large-scale operations.

Q: Do you buy used Arista 7020R hardware?
Yes. BrightStar Systems actively buys used 7020R switches and other Arista hardware. If you are decommissioning or refreshing, we can provide bids and help you recover value from surplus equipment.

Q: Are used 7020R switches suitable for production use?
Yes. Many customers deploy used and refurbished 7020R switches in production environments. Our lab testing, cleaning, and warranty coverage are designed to make pre-owned 7020R hardware a reliable option for critical workloads.

Q: What optics and cables are supported on 7020R uplinks?
7020R switches support a wide range of Arista SFP, SFP+, and QSFP optics along with DAC and AOC cables. Compatibility depends on the specific model and EOS version; our team can help you select supported optics for your deployment.

Q: Can I mix 7020R with other Arista 7000 Series switches in the same network?
Yes. It is common to use 7020R at the storage or edge layer while using 7050X, 7060X, or 7280 platforms as spine or aggregation switches within the same EOS-based fabric.
