Understanding QFX3000-G QFabric System Hardware Configurations
The QFX3000-G QFabric system is made up of multiple hardware components:
• EX4200 switches—Eight EX4200 switches are required for a 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
