Juniper QFX10000 Series Switches

Juniper QFX10000 Series Switches (Used & Refurbished)
The Juniper QFX10000 Series is Juniper’s flagship data center switching family for large-scale leaf–spine fabrics, cloud core, and high-performance enterprise networks. With a combination of fixed QFX10002 platforms and modular QFX10008 / QFX10016 chassis, the QFX10000 line delivers massive 10/25/40/100GbE scale, deep buffers, and rich EVPN-VXLAN and MPLS capabilities for modern data center designs. BrightStar Systems supplies fully tested used and refurbished QFX10000 switches backed by our 1-Year In-House Warranty, helping you build or expand high-performance fabrics at a fraction of new hardware cost.

QFX10000 platforms are ideal in roles where you need dense 100GbE, predictable latency, and strong control-plane scale, including spine layers, collapsed core/aggregation, or even high-end leaf deployments with heavy east–west traffic.
Juniper QFX10000 Series Overview
The QFX10000 Series is built around Juniper’s custom Q5 ASICs and is designed to serve as a flexible building block for EVPN-VXLAN fabrics, Layer 3 Clos designs, and multi-tenant cloud environments. The series includes fixed 2RU QFX10002 switches and large modular QFX10008 and QFX10016 chassis that can be scaled to very high port densities.

Key features of the QFX10000 Series include:

High-density 100GbE and 40GbE switching with support for 10GbE and 25GbE breakout on many models.
Both fixed-configuration (QFX10002) and modular chassis (QFX10008, QFX10016) options for scalable core and spine designs.
Rich L2/L3 feature set including EVPN-VXLAN, MPLS, L2/L3 VPNs, and advanced QoS.
Deep buffers and advanced congestion management for demanding east–west and storage traffic.
Programmable, automation-friendly platform powered by Junos OS.

Many operators use QFX10000 as the high-capacity core or spine layer while using QFX5120 and QFX5130 at the leaf and MX Series routers at the edge or WAN.

Comparing QFX10000 to Other Juniper & Arista Platforms
When designing a new fabric or upgrading an existing core, many organizations evaluate QFX10000 against smaller QFX platforms and competing high-end switches. BrightStar Systems carries both Juniper and Arista hardware and can help you compare options based on scale, feature set, and long-term operating cost.

Juniper QFX5100 Series – Flexible 10/40G leaf or small spine switches.
Juniper QFX5120 Series – 25G/100G leaf and aggregation.
Arista 7050X Series – Commonly used for L3 leaf roles.
