Planning a QFX3000-G QFabric System Deployment
A QFX3000 QFabric system is formed by interconnecting QFX3500 Node devices,
QFX3008-I Interconnect Devices, and QFX3100 Director devices. Two Virtual Chassis,
composed of four EX4200 switches each, are used to interconnect the control plane
and management network.
Before installing a QFabric system, you must consider the following factors:
•
The number of devices in the QFabric system and location—You can interconnect up
to 128 QFX3500 Node devices and 4 QFX3008-I Interconnect Devices; each QFabric
system must have 2 QFX3100 Director devices operating in a Director group. For
information about the size and strength of racks for the devices, see the following
topics:
