The Juniper Networks QFX10008 Modular Data Center Switch is a high-performance, scalable switching platform designed for data center core, spine, campus core, and service provider networks. Built in a 13RU chassis with 8 line card slots, the QFX10008 delivers massive throughput, advanced automation, and future-ready architecture for modern high-bandwidth environments.
Powered by Juniper’s advanced Q5 ASIC technology, the QFX10008 provides deep packet buffering with Hybrid Memory Cube (HMC), enabling superior performance during traffic bursts and congestion scenarios. With support for up to 42 Tbps switching capacity and 11.4 Bpps forwarding rate, it ensures wire-speed performance for even the most demanding workloads.
The modular design supports a wide range of interfaces, including 10GbE, 40GbE, 100GbE, and 400GbE-ready line cards, allowing organizations to scale their infrastructure seamlessly as network demands grow. This flexibility makes the QFX10008 an ideal solution for hyperscale data centers, cloud environments, and high-performance enterprise networks.
Engineered for modern network fabrics, the QFX10008 offers full support for EVPN-VXLAN, enabling scalable Layer 2 and Layer 3 overlays for software-defined networking (SDN). It also supports advanced routing protocols such as BGP, OSPF, and IS-IS, ensuring seamless integration into complex network architectures.
Designed for high availability, the chassis includes 1+1 control plane redundancy, N+1 or N+N power redundancy, and redundant fan trays, ensuring continuous operation in mission-critical environments. Its modular architecture allows independent upgrades of line cards and switch fabric modules, providing long-term investment protection and reducing upgrade costs.
Fully integrated with Junos OS, and compatible with automation tools such as Python, Ansible, Puppet, and Chef, the Juniper QFX10008 delivers a powerful combination of performance, scalability, and operational efficiency, making it a cornerstone platform for next-generation data center networking.

FAQs:
Q1. How many 100GbE ports can I fit in a QFX10008?
Using the QFX10000-LC2101 line card, which offers 30 ports of 100GbE, a fully loaded QFX10008 can support up to 240 ports of 100GbE in a single chassis.
Q2. Does this switch support 400GbE?
Yes. With the introduction of the QFX10000-LC4800 line cards, the QFX10008 can be upgraded to support high-density 400GbE interfaces.
Q3. What is the benefit of the "backplane-less" design?
The QFX10000 series uses an orthogonal direct-connect architecture where line cards connect directly to the switch fabric modules. This eliminates the need for a midplane, improving airflow and increasing signal integrity for higher speeds.
Q4. Can I use the same line cards in the QFX10008 and QFX10013?
Yes. The QFX10000 modular line cards are interchangeable between the 8-slot (10008) and 13-slot (10013) chassis.
Q5. Is the QFX10008 compatible with DC power?
Yes. The chassis supports hot-swappable AC, DC, and Universal (High-Voltage AC/DC) power supply options to meet various data center requirements.
