For added flexibility, the 40GbE ports on all QFX5100 switches can be used as 4x10GbE ports using QSFP+ to SFP+ direct attach copper (DAC) or QSFP+ to SFP+ fiber splitter cables and optics. With splitter cables, the QFX5100-48S supports up to 72 10GbE ports, while the QFX5100-24Q and QFX5100-96S support up to 104 10GbE ports.

Junos Space Network Director

The QFX5100 switches can be managed through Junos Space Network Director, a next-generation network management solution that allows users to visualize, analyze, and control the entire enterprise network—data center and campus, physical and virtual, wired and wireless—through a single pane of glass. Network Director incorporates sophisticated analytics for realtime intelligence, trended monitoring, and automation to increase agility as well as faster rollout and activation of services.

For cloud deployments, Network Director provides a set of REST APIs that enable on-demand and dynamic network services by simplifying the consumption of services for multitenant environments. With third-party cloud orchestration tool integration, the Network Director API enables automation and provisioning of Layer 2, Layer 3, and security services in the data center without the need for manual operator intervention.

Virtual Chassis Technology

The QFX5100 supports Juniper Networks’ unique Virtual Chassis technology, which enables up to 10 interconnected switches to be managed and operated as a single, logical device with a single IP address. Virtual Chassis technology enables enterprises to separate physical topology from logical groupings of endpoints and, as a result, provides efficient resource utilization. All QFX5100 switches can participate in the same Virtual Chassis configuration, along with any combination of EX4300, QFX3500, and QFX3600 Ethernet switches, delivering highly flexible and scalable configuration options for data center deployments.

Virtual Chassis Fabric Switching Architecture

Existing Virtual Chassis technology is further scaled and enhanced to support a spine-and-leaf topology that is ideal for highperformance and low-latency data center deployments. In its first instance, this topology, called Virtual Chassis Fabric, enables up to 20 QFX5100 switches to be deployed in a spine-and-leaf configuration, with two to four QFX5100s in the spine and up to 18 QFX5100s as leaf nodes. This architecture provides any-rack-toany-rack deterministic throughput and less than 3 microseconds of latency, while significantly simplifying network operations through a single point of management. EX4300, QFX3500, and QFX3600 switches can also act as leaf nodes in a Virtual Chassis Fabric deployment, providing support for data centers with mixed 1GbE, 10GbE, and 40GbE servers as well as environments transitioning from 1GbE to 10GbE or 40GbE servers while protecting existing EX4300, QFX3500, and QFX3600 investments.

The QFX5100 also supports a Layer 2 VxLAN Gateway feature in Virtual Chassis Fabric mode, creating a single Hardware VTEP for an entire Virtual Chassis Fabric pod (a single management domain of up to 20 devices) that would exist on all nodes. Virtual Chassis Fabric enables a plug-and-play architecture; hence no VTEP configuration changes are required when adding or removing nodes from the Virtual Chassis Fabric pod. For MAC address learning, Virtual Chassis Fabric supports both EVPN as well as OVSDB, and also integrates with VMware NSX.

Junos Fusion

Junos Fusion, an IEEE 802.1Br standards-based Ethernet fabric, is ideal for mid-to-large data center customers who want simplicity at scale.

The open, easy-to-deploy Junos Fusion provides a single point of management and plug-and-play operation for networks with a choice of 1GbE, 10GbE and 40GbE for server access. In a Junos Fusion deployment, QFX5100 switches are deployed as Satellite devices that are managed by the QFX10000 switches deployed as Aggregation devices. (see Figure 1).

Figure 1: Junos Fusion deployments using QFX1000 switches as Aggregation devices and EX4300 and QFX5100 switches as Satellite devices.
Figure 1: Junos Fusion deployments using QFX1000 switches as Aggregation devices and EX4300 and QFX5100 switches as Satellite devices.

QFabric System

The QFX5100-48S and QFX5100-48T can also act as a QFabric Node device in a QFX3000-M and QFX3000-G QFabric System. The QFX5100-48S and QFX5100-48T are fully interoperable with existing QFX3500 and QFX3600 QFabric Nodes, providing backward compatibility and investment protection. With a mixture of QFX3500, QFX3600, and QFX5100 Nodes, a QFabric System can scale on a node by node basis without being limited by the lowest common denominator.

Data Center Deployments

Today’s data centers are built with high-performance, small form-factor, multicore blade and rack servers. The greater compute capacity and server densities enabled by these devices is increasing traffic levels, creating the need for high-speed, lowlatency, storage- and I/O-converged networking solutions that can maximize performance for physical servers, virtual servers, and storage in the data center.

The QFX5100 line offers a portfolio of switches that deliver the low-latency, lossless, high-density 10GbE and 40GbE interfaces with the Fibre Channel over Ethernet (FCoE) transit switch functionality demanded by today’s data center. All QFX5100 models are designed to consume the lowest power possible while optimizing space, thereby reducing data center operating costs. Flexible airflow direction options enable the QFX5100 to support back-to-front and front-to-back cooling, ensuring consistency with server designs for hot- and cold-aisle deployments.

Data Center Server Access

The QFX5100 line of switches is ideal for top-of-rack deployments of various densities and speeds. The compact 1 U QFX5100-48S offers 48 ports of native 10GbE for server connectivity and up to six 40GbE ports for uplink connectivity, providing very low oversubscription of 2:1 from access to aggregation. Each 40GbE port can be further broken out into four 10GbE ports, providing additional 10GbE for server connectivity.

The QFX5100-48T offers 48 RJ-45-based 10GbE ports and up to six 40GbE ports for providing uplinks to aggregation switches. Each RJ-45 port can operate in three different speeds, providing 10GbE, 1GbE or 100 Mbps server connectivity using the same shielded twisted pair copper cables. Distances up to 100m can be supported using cables that conform to IEEE 802.3-2012 specifications, enabling the QFX5100-48T to be deployed as a top-of-rack, middle-of-row or end-of-row switch.

The 2 U QFX5100-96S is a high-density native 10GbE data center access switch that is ideal for deployments with a high degree of application redundancy. The highly efficient QFX5100-96S offers 96 ports of native 10GbE for server connectivity and eight 40GbE ports for uplink connectivity, providing very low oversubscription of 3:1 from access to aggregation.

The QFX5100-24Q offers 24 QSFP+ ports in the base unit with an option to scale up to 32 QSFP+ ports with two four-port expansion modules. Each QSFP+ port can be used for native 40GbE server port connectivity or channelized into four 10GbE ports for 10GbE server connectivity, offering maximum flexibility and investment protection for data center growth.

Each of the QFX5100 switches can operate in both cut-through and store-and-forward modes, delivering sustained wirespeed switching with sub-microsecond latency and low jitter for any packet size (including jumbo frames) in both modes. All QFX Series switches support extensive Layer 2 features, enabling the device to support high-density 10GbE/FCoE Layer 2 access deployments. With features such as multi-chassis link aggregation group (MC-LAG), the QFX5100 supports active/active server dual homing and can utilize full bisectional bandwidth from server to switch. When the QFX5100 is deployed in the access layer, MC-LAG on QFX10000 switches in the aggregation layer provides maximum resiliency and full Layer 2 multi-pathing in the network (see Figure 2).

The Junos operating system features the most advanced and robust routing capabilities in the industry. All QFX5100 switches include support for RIP and OSPF for both IPv4 and IPv6 in the base software. Advanced routing capabilities such as IS-IS and BGP are also supported. With additional capabilities like 64-way equal-cost multipath (ECMP) and BGP add path, the QFX5100 is an ideal building block for deploying the most robust Layer 3 underlay for software-defined networks (SDN) (see Figure 3).

Figure 3: Larger scale data center with Layer 3 to the access

In addition, the QFX5100 also supports Virtual Chassis Fabric and QFabric System deployments. These fabric technologies support both Layer 2 multi-pathing and Layer 3 ECMP paths within the same network fabric while dramatically reducing the number of user configured protocols, thus eliminating the need to run protocols such as Virtual Router Redundancy Protocol (VRRP) for Layer 3 gateway load balancing and complex multicast protocols to set up replication trees. Virtual Chassis Fabric and QFabric technology dramatically reduce the complexity and cost of managing the data center network by making multiple switches appear as a single, logical device. Virtual Chassis Fabric allows up to 20 individual switches to be managed via a single CLI, while a QFabric System enables up to 128 Nodes to operate as a single device (see Figures 4 and 5).

Features and Benefits:

  • Topology-Independent In-Service Software Upgrade (TISSU*): With its Intel core processor, the QFX5100 allows Junos OS to run within a virtual machine (VM) on Linux. Junos OS runs in two separate VMs in active and standby pairs; during software upgrade cycles, the switches seamlessly move to the newer software version while maintaining intact data plane traffic. This true TopologyIndependent ISSU, an industry-first software upgrade feature for a fixed-configuration top-of-rack switch, is supported across all Layer 2 and Layer 3 protocols and doesn’t need the support of any other switches to perform an image upgrade.

  • Automation: The QFX5100 switches support a number of features for network automation and plug-and-play operations. Features include zero-touch provisioning, operations and event scripts, automatic rollback, and Python scripting. The switch also offers support for integration with VMware NSX Layer 2 Gateway Services, Puppet, and OpenStack.

  • Flexible Forwarding Table: The QFX5100’s Flexible Forwarding Table (FFT) allows the hardware table to be carved into configurable partitions of Layer 2 media access control (MAC), Layer 3 host, and Longest Prefix Match (LPM) tables. In a pure L2 environment, the QFX5100 supports 288,000 MAC addresses. In L3 mode, the table can support 128,000 host entries, and in LPM mode, it can support 128,000 prefixes. Junos OS provides configurable options through a commandline interface (CLI) so that each QFX5100 can be optimized for different deployment scenarios.

  • Intelligent Buffer Management: The QFX5100 switches have a total of 12 MB shared buffers. While 25% of the total buffer space is dedicated, the rest is shared among all ports and is user configurable. The intelligent buffer mechanism in the QFX5100 effectively absorbs traffic bursts while providing deterministic performance, significantly increasing performance over static allocation.

  • Insight Technology for Analytics: The QFX5100 provides dynamic buffer utilization monitoring and reporting with an interval of 10 milliseconds to provide microburst and latency insight. The data can be viewed via CLI, system log, or streamed to external servers for more analysis. Supported reporting formats include Java Script Object Notification (JSON), CSV and TSV. These files can be consumed by orchestration systems, SDN controllers, or network management applications (such as Juniper Networks Junos Space Network Director) to make better network design decisions and identify network hotspots.

  • MPLS: QFX5100 switches support a broad set of MPLS features, including L3 VPN, IPv6 provider edge router (6PE), RSVP traffic engineering, and LDP to allow standards-based network segmentation and virtualization. The QFX5100 can be deployed as a low-latency MPLS label-switching router (LSR) or MPLS PE router in smaller scale environments. The QFX5100 is the industry’s only compact, low-latency, highdensity, low-power switch to offer an MPLS feature set.

  • VXLAN: The QFX5100 supports Layer 2 gateway services that enable VXLAN-to-VLAN connectivity at any tier of the data center network, from server access to the edge. For MAC address learning, the QFX5100 supports both EVPN as well as OVSDB, and also integrates with VMware NSX.

  • FCoE: As a Fibre Channel over Ethernet (FCoE) transit switch, the QFX5100 provides an IEEE data center bridging (DCB) converged network between FCoE-enabled servers and an FCoE-enabled Fibre Channel storage area network (SAN). The QFX5100 offers a full-featured DCB implementation that provides strong monitoring capabilities on the top-of-rack switch for SAN and LAN administration teams to maintain clear separation of management. In addition, FCoE Initiation Protocol (FIP) snooping provides perimeter protection, ensuring that the presence of an Ethernet layer does not impact existing SAN security policies. FCoE link aggregation group (LAG) active/active support is available to achieve resilient (dual-rail) FCoE connectivity.

The FCoE transit switch functionality, including priority-based flow control (PFC), Enhanced Transmission Selection (ETS), and Data Center Bridging Capability Exchange (DCBX), are included as part of the default software.
