group to the management ports of the Node and Interconnect devices. By keeping the
control plane network separate from the data plane, the QFabric system can scale to
support thousands of servers and storage devices.
The four major QFabric system components can be assembled from a variety of hardware
options. Currently supported hardware configurations are shown in
Table 5 on page 17 .

group QFX3000-G
QFabric system
Two EX4200 Ethernet
switches
NOTE: For a
copper-based
QFX3000-M QFabric
system control plane
network, use
EX4200-24T switches
with an SFP+ uplink
module installed. For a
fiber-based control plane
network, use
EX4200-24F switches
with an SFP+ uplink
module installed.
QFX3600-I
Interconnect device
NOTE: There can be
a maximum of four
Interconnect devices
in the QFX3000-M
QFabric system.
QFX3500 and QFX3600 Node
device
NOTE:
• There can be a maximum of
16 Node devices in the
QFX3000-M QFabric
system.
• For a copper-based
QFX3000-M QFabric
system control plane
network, use QFX3500
Node devices with a
1000BASE-T management
board installed. For a
fiber-based control plane
network, use QFX3500
Node devices with an SFP
management board
installed.
QFX3100 Director
group
NOTE: For a
copper-based
QFX3000-M QFabric
system control plane
network, use QFX3100
Director devices with
RJ-45 network
modules installed. For
a fiber-based control
plane network, use
QFX3100 Director
devices with SFP
network modules
installed.
QFX3000-M
QFabric system
To complete the system, external Routing Engines (such as the fabric manager Routing
Engines, network Node group Routing Engines, and fabric control Routing Engines) run
on the Director group and implement QFabric system control plane functions. The control
plane network provides the control plane connections between the Node devices, the
Interconnect devices, and the Routing Engines running on the Director group.
