QFABRIC SYSTEM Product Overview Modern data centers demand scale, performance, flexibility, and control— along with reductions in total cost of ownership (TCO). Juniper Networks QFabric architecture is a revolutionary approach that provides a foundation for cloud-ready virtualized data center network environments. Juniper Networks QFabric System is the cornerstone of the QFabric architecture—a purpose-built solution that allows the creation of highperformance, scalable, cost-effective, dynamic, and easy to manage large enterprise IT or service provider cloud data centers. Product Description Juniper Networks® QFabric™ System is the only fabric solution that delivers any-to-any connectivity and simplified operations, making it the ideal architectural foundation for virtualized data centers today and for the next decade. It is a scalable, high-performance, non-blocking, and easy-to-manage fabric that enables traditional Layer 2 and Layer 3 connectivity along with virtualization and convergence. The standards-based QFabric System is completely interoperable and seamlessly integrates with customers’ existing data center environments, allowing them to easily migrate traditional tiered networks to a single tier QFabric architecture that connects compute, storage, network, and services resources as extensions of a low latency network. QFabric technology enables customers to maximize the performance of their data centers and simplify their network operations. By providing direct connectivity and predictable high performance at scale between any two ports in the fabric, common changes in the data center such as adding capacity, virtual machine mobility, or deploying new applications can be achieved quickly and easily. Two QFabric System models are available: • The QFX3000-M QFabric System, designed for mid-tier, satellite, and container data center environments, supports from 48 to 768 10GbE ports, delivering the simplicity, agility, and performance benefits of QFabric architecture in a space optimized form factor. The QFX3000-M is ideal for High Performance Computing environments, Big Data Hadoop clusters, and back-end business applications, and it provides investment protection by allowing customers to easily scale to a larger QFabric system deployment as demands for 10GbE grow. • The QFX3000-G QFabric System, designed for large enterprises, service providers, and cloud data center environments, scales to support up to 6,144 10GbE ports in a single device. The QFX3000-G is ideal for cloud (IaaS, SaaS), large enterprise IT data center (business applications, data analytics), and High Performance Computing (grid computing, data modeling, scientific research) environments.

• QFabric Director: The Routing Engines embedded within a modular switch are externalized in the QFabric system via the QFX3100 QFabric Director, which provides control and management services for the fabric. Deployed in clusters to provide redundancy, QFabric Directors provide a single management interface to manage the scalable data plane provided by the Node and Interconnect devices.

This out-of-band network is used for auto-discovery of all devices, provisioning, image upgrades for various elements in the system, and configuration. All of these functions are fully automated and do not require user configuration. • Management plane: The Director provides all management services for the QFabric architecture, communicating directly with all Node and Interconnect devices to build a global view of the entire network. This provides a single point of visibility, control, and management for the entire data center fabric, and it significantly reduces the operational costs...

QFabric System Features and Benefits Feature Multi-terabit capacity and scalability The QFabric architecture allows for scale and incremental growth by adding a QFabric Node when a new server rack is installed. With the QFabric Interconnect acting as the network backplane with a capacity of 5.12 Tbps in a QFX3000-M system and 40 Tbps in a QFX3000-G system, the QFabric architecture scales to support up to 6,144 10GbE ports, with the ability to scale beyond 10GbE in the future for both types of systems. The incremental investment required to connect new server and storage capacity is a...

QFabric Architecture Management Capabilities The following system management options are available for the QFabric system: • The standard Junos OS CLI and SNMP module offers the same granular management capabilities and scripting parameters found in any router or switch powered by Junos OS. • Performance, configuration, and fault data for the QFabric architecture can also be exported to leading third-party management systems such as HP OpenView, IBM Tivoli, and Computer Associates Unicenter software, providing a complete, consolidated view of network operations. • QFabric technology is...
