Table 3: QFabric System Terms (continued)
Definition Term
QFabric system component that acts as the primary fabric for data plane traffic
traversing the QFabric system between Node devices. An example of an
Interconnect device is a QFX3008-I Interconnect device. (See also
Node device .)
Interconnect device
Carrier-class network management system for provisioning, monitoring, and
diagnosing Juniper Networks routing, switching, security, and data center
platforms. Junos Space
Set of one to eight Node devices that connects to an external network. network Node group
Virtual Junos OS Routing Engine instance that handles routing processes for
a network Node group. The network Node group Routing Engine runs on the
Director group. network Node group Routing Engine
Routing and switching device that connects to endpoints (such as servers or
storage devices) or external network peers, and is connected to the QFabric
system through an Interconnect device. You can deploy Node devices similarly
to the way a top-of-rack switch is implemented. An example of a Node device
is the QFX3500 Node device. (See also
Interconnect device and network Node
group .)
Node device
Collection of physical or logical QFabric system hardware components (such
as Node devices) that provides fault isolation, separation, and security.
In their initial state, all QFabric system components belong to a default partition .
partition
Highly scalable, distributed, Layer 2 and Layer 3 networking architecture that
provides a high-performance, low-latency, and unified interconnect solution
for next-generation data centers. A QFabric system collapses the traditional
multi-tier data center model, enables the consolidation of data center
endpoints (such as servers, storage devices, memory, appliances, and routers),
and provides better scaling and network virtualization capabilities than
traditional data centers.
Essentially, a QFabric system can be viewed as a single, nonblocking,
low-latency switch that supports thousands of 10-Gigabit Ethernet ports or
2-Gbps, 4-Gbps or 8-Gbps Fibre Channel ports to interconnect servers, storage,
and the Internet across a high-speed, high-performance fabric. The QFabric
system must have sufficient resources and devices allocated to handle the
Director group , Node device , and Interconnect device functions and capabilities.
