The Juniper Networks QFabric family of products offers a revolutionary approach that delivers dramatic improvements in data center performance, operating costs, and business agility for enterprises, high-performance computing systems, and cloud providers. The QFabric family implements a single-tier network in the data center, enabling improvements in speed, scale and efficiency by removing legacy barriers and improving business agility.
The QFabric family includes three members:
- QFabric System: Composed of three separate components—the QFabric Node, QFabric Interconnect and QFabric Director—the QFabric System creates a high-performance, low-latency fabric that unleashes the full power of the data center with the simplicity of a single switch.
- QFabric Node acts as the entry and exit into the fabric
- QFabric Interconnect is the high-speed transport device for interconnecting QFabric Nodes
- QFabric Director provides control and management services to deliver a common window for managing all devices as a single device.
- QFX3500 Switch: The QFX3500 is a standalone 48-port 10GbE top-of-rack switch with four 40GbE uplink ports and Fibre Channel over Ethernet (FCoE) and FC gateway functionality. With a simple software and configuration change, the QFX3500 can also provide the QFabric Node functionality in a QFabric System.
- QFX3600 Switch: The QFX3600 offers 16 QFSP+ ports, delivering a high-performance, feature-rich 40GbE/10GbE top-of-rack switch with iSCSI and FCoE functionality for highly demanding data center environments (available 2H12). The QFX3600 also provides QFabric Node functionality in a QFabric System.
The highly scalable, low-latency QFabric System supports thousands of ports within a single-tier data center or cloud, enabling any-to-any connectivity with the simplicity of a single, highly resilient switch.
The QFabric System, composed of multiple components working together as a single switch, delivers any-to-any connectivity, high performance, and management simplicity, making it the ideal foundation for cloud-ready, virtualized data center environments.
The QFabric components appear as a single switch, enabling any-to-any connectivity for servers, storage, existing network components, and other critical systems in the data center while providing a foundation for cloud-ready, virtualized and mobile computing environments.
The QFabric System components include:
- QFabric Nodes, high-density, fixed-configuration edge devices that connect to servers, storage and other networking devices using standards-based Ethernet interfaces, providing access into and out of the fabric
- QFabric Interconnect, a high-speed transport device that connects all QFabric Node edge devices in a full- mesh topology
- QFabric Director, which provides all control and management services for the QFabric System, enabling it to be managed and operated as a single device
The QFabric System is highly scalable and has unmatched simplicity that improves application performance by delivering low latency and converged services in a nonblocking and lossless architecture. Featuring Layer 2, Layer 3 and Fibre Channel over Ethernet (FCoE) capabilities, the QFabric System is available in two models:
- QFabric QFX3000-M, designed for mid–tier, satellite and container data center environments, supports up to 768 10GbE ports with an average latency of 3 microseconds port to port
- QFabric QFX3000-G, designed for large enterprises, service providers, and cloud data center environments, supports up to 6,144 10GbE ports with an average latency of 5 microseconds port to port
For investment protection, existing QFabric System components can be redeployed between the two models, greatly simplifying flexibility and migration. For example, users can initially deploy a QFX3000-M and, as their 10GbE demands grow, they can migrate to a QFX3000-G with the simple replacement of the QFabric Interconnect, dramatically increasing scale.

The QFX3600 delivers a high-performance, low-latency 40GbE/10GbE fabric-ready edge solution for Juniper Networks QFabric System, as well as a versatile Layer 2 and Layer 3 standalone top-of-rack switch for demanding data center.
The QFX3600 Switch is a high-performance, low-latency, feature-rich 40GbE*/10GbE platform that delivers a fabric-ready edge solution for the Juniper Networks QFX3000-M and QFX3000-G QFabric Systems.
Featuring standards-based bridging, routing and Fibre Channel over Ethernet (FCoE) capabilities in a compact 1U form factor, the QFX3600 is also a versatile Layer 2 and Layer 3 standalone data center top-of-rack switch.*
The first 40GbE top-of-rack switch in the Juniper Networks switching portfolio, the QFX3600 addresses a wide range of deployment scenarios—including traditional data centers, virtualized data centers, high-performance computing, network-attached storage, converged server I/O, and cloud computing.
Featuring 16 QSFP+ ports, the QFX3600 delivers feature-rich Layer 2 and Layer 3 connectivity to networked devices such as rack servers, blade servers, storage systems and other switches in highly demanding, high-performance data center environments. When deployed with other components of the QFabric product family, including the QFX3100 Director and the QFX3600-I QFabric Interconnect in a
