Understanding QFX3000-G QFabric System Hardware Configurations
The QFX3000-G QFabric system is made up of multiple hardware components:
•
EX4200 switches—EightEX4200 switches are required fora QFX3000 QFabric system.
The EX4200 switches are divided into two Virtual Chassis configurations with four
switches each.
•
Up to 192 Gigabit Ethernet RJ-45 ports on each Virtual Chassis provide control plane
and management network interconnection.
•
Four 10-Gigabit Ethernet uplink ports on each Virtual Chassis interconnect the two
Virtual Chassis configurations.
•
QFX3100 Director devices—Two QFX3100 Director devices are required for a QFX3000
QFabric system. Together, the two Director devices are called a Director group.
•
Six Gigabit Ethernet RJ-45 ports on each QFX3100 Director device provide connection
to the control plane and management network through the Virtual Chassis.
•
Two Gigabit Ethernet RJ-45 ports on each QFX3100 Director device interconnect
two Director devices in a Director group.
•
One Gigabit Ethernet RJ-45 management port on each QFX3100 Director device
provides connection to the management network through your out-of-band
management network.
•
QFX3500 Node devices—Up to 128 QFX3500 Node devices can be connected to the
QFX3000 QFabric system.
•
48 10-Gbps SFP+ ports on each QFX3500 Node device connect to servers, storage,
or external networks. Twelve of these ports (0 through 5 and 42 through 47) can be
configured as 2-Gbps, 4-Gbps, or 8-Gbps Fibre Channel ports, and 36 of these ports
(6 through 41) can be configured as Gigabit Ethernet ports. There are no limitations
on which ports can be configured as 10-Gigabit Ethernet ports. However, if you are
