The QFX3008-I Interconnect device is a half-rack, modular, fully redundant chassis that
provides the data plane switch fabric for Juniper Networks QFX3500, QFX3600, and
QFX5100 Node devices. Together the Node device and the QFX3008-I Interconnect
device form a multistage, nonblocking switch fabric that provides a high-performance,
low-latency, unified interconnect solution for next-generation data centers. See
Understanding the QFabric System Data Plane.
The Node devices and QFX3008-I Interconnect Devices are connected to Juniper Networks
QFX3100 Director devices in an out-of-band management network through Juniper
Networks EX4200 Ethernet Switches. The QFX3100 Director devices present the QFabric
system devices as a single network entity, which enables simplified management of your
