to either a QFX3600-I Interconnect device to a QFX5100-24Q through the 40-Gbps uplink ports.Together,
the QFX3600 Node devices and Interconnect devices form a multistage, nonblocking switch fabric that
provides a high-performance, low-latency, unified interconnect solution for next-generation data centers.
The QFX3600 Node devices and QFX3008-I or QFX3600-I Interconnect devices are connected to Juniper
Networks QFX3100 Director devices in a control plane and management network. The QFX3100 Director
device presents the QFabric system devices as a single network entity, allowing for simplified management
of your data center using the Junos OS command-line interface (CLI).
In a QFX Virtual Chassis, the QFX3600 device can participate with other QFX3600 devices or QFX3500
devices in a ring topology with up to 10 members.
In a QFX5100 Virtual Chassis Fabric, the QFX3600 device can participate as a leaf device. Up to a total
of 32 devices can participate in the Virtual Chassis Fabric.
Software
QFX Series devices use the Junos operating system (OS), which provides Layer 2 and Layer 3 switching,
routing, and security services. Junos OS is installed on the QFX3600 device’s 8-gigabyte (GB) internal flash
drive. The same Junos OS code base that runs on QFX Series devices also runs on all Juniper Networks
EX Series, J Series, M Series, MX Series, and T Series devices.
For more information about which features are supported on QFX Series devices, see Feature Explorer.
When the QFX3600 device is operating as a standalone switch, you manage the switch using the Junos
OS command-line interface (CLI), accessible through the console and out-of-band management ports on
the device.
When a QFX Series device operates as part of a QFabric system, all the devices in the data center fabric
are managed through the Administrator software installed on the QFX3100 Director devices. Each device
in a QFabric system is interconnected in a single control plane and management network, using the
redundant management ports on each device.
Hardware
The compact QFX3600 chassis is 1 rack unit (1 U) in size and designed to fit in industry-standard 19-inch
rack-mount enclosures, as well as high-density server racks and container-based data center deployments.
See Figure 21 on page 47 and Figure 22 on page 47 and Chassis Physical Specifications for QFX3600 and
QFX3600-I Devices.
