QFX3600-I QFabric
Interconnect
Product Overview
The QFX3600-I QFabric Interconnect
provides the high-speed transport
that serves as the backplane of
a QFX3000-M QFabric System,
supporting data centers with up to
16 racks where each rack contains 48
10GbE compute and storage network
ports. The QFX3000-M—consisting of
QFX3500 and/or QFX3600 QFabric
Nodes, the QFX3600-I QFabric
Interconnect and the QFX3100
QFabric Director—operates and is
managed as a single, logical device
for supporting the next-generation
virtualized and high-performance
data center, lowering capital,
management, and operational
expenses
Product Description
Juniper Networks® QFX3600-I QFabric Interconnect is a fixed, 1 U device that acts as
the backplane of a Juniper Networks QFX3000-M QFabric System, connecting any
combination of QFX3500 and QFX3600 QFabric Node edge devices in a full mesh
topology in 6:1, 3:1, or non-oversubscribed configurations.
High availability features on the QFX3600-I QFabric Interconnect include three fan
trays with a 2+1 redundancy model and redundant AC or DC power supplies. Featuring a
switching capacity of 1.28 Tbps, the QFX3600-I offers 16 40 Gbps ports, providing data
plane connectivity for the QFabric Nodes. Each QFabric Node connects to the QFX3600-I
QFabric Interconnect via one to four 40 Gbps interfaces operating over standard OM3/
OM4 multimode fiber optic cables. Similar to the fabric inside a modular switch, there
are no connections between the QFX3600-I QFabric Interconnects in the data center;
the QFabric Interconnect only provides transport between QFabric Node devices. Four
fully populated QFX3600-I QFabric Interconnects can scale the QFabric architecture to
support 768 10GbE customer-facing ports, with an aggregate capacity of 5.12 Tbps and
average port-to-port latency of 3 micro-seconds. Each component within a QFX3000-M
system data path has an average latency of 1 microsecond.
The QFX3600-I runs the same Juniper Networks Junos® operating system as other Juniper
Networks switches, routers, and security devices. All provisioning and management is
done via the Juniper Networks QFX3100 QFabric Director. The control plane between
the QFX3600-I Interconnect and the QFabric Director is established over a redundant
out-of-band copper or fiber control plane network using Juniper EX4200 switches. The
QFX3600-I Interconnect has two copper 1GbE ports and two fiber 1GbE ports, either of
which can be used to connect the Interconnect to the Director.
