Data Center Deployments

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

The QFX5110 switches deliver low-latency, lossless, high-density 10GbE and 40GbE interfaces, as well as 100GbE uplinks to the core network demanded by today’s data center. Furthermore, the QFX5110 offers VXLAN Layer 2 and Layer 3 gateway support, making it an ideal solution for overlay deployments in the data center. All QFX5110 switches are designed to consume the lowest possible power while optimizing space, reducing data center operating costs. Flexible airflow direction options enable the QFX5110 switches to support back-to-front and front-to-back cooling, ensuring consistency with server designs for hot-aisle or cold-aisle deployments.

Data Center Server Access

The QFX5110 switches are ideal for top-of-rack deployments of various densities and speeds. The QFX5110-48S offers 48 ports of native 10GbE for server connectivity, plus up to four 40GbE or 100GbE ports for uplink connectivity, providing very low oversubscription of 1.2:1 from access to aggregation. Meanwhile, the QFX5110-32Q offers 20 QSFP+ 40GbE ports for server connectivity and up to four 100GbE ports for uplink connectivity, providing an oversubscription of 2:1 from access to aggregation. Each 40GbE port can be further broken out into four 10GbE ports, providing additional options for server connectivity.

The QFX5110 switches can operate in both cut-through and store-and-forward modes, delivering sustained wire-speed 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 Layer 2 access deployments. With features such as multichassis link aggregation group (MC-LAG), the QFX5110 supports active/active server dual homing and can utilize full bisectional bandwidth from server to switch. When the QFX5110 is deployed in the access layer, MC-LAG on QFX10000 switches in the aggregation layer provides maximum resiliency and full Layer 2 multipathing in the network.

The Junos OS features the most advanced and robust routing capabilities in the industry. All QFX5110 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 QFX5110 is an ideal building block for deploying the most robust Layer 3 underlay for SDN.

Campus Deployments

Juniper Networks campus fabrics provide a single, standards-based Ethernet VPN-Virtual Extensible LAN (EVPN-VXLAN) solution that can be deployed in any campus, whether a two-tier network with a collapsed core distribution or a campus-wide system that involves multiple buildings with separate distribution and core layers.

The QFX5110-48S switch is ideal as campus distribution switches with 10GbE downlinks and 40GbE/100GbE uplinks supporting technologies like MC-LAG and EVPN multihoming.

The QFX5110-32Q switch is ideal as a campus core switch with 32 ports of 40GbE and support for campus fabric with EVPN-VXLAN.

Juniper campus fabrics support these validated architectures: 

  • MC-LAG and EVPN Multihoming (Collapsed Core/Distribution). A pair of interconnected QFX5110 switches can be deployed to provide EVPN multihoming (ESI-LAG) or multichassis link aggregation (MC-LAG) in a collapsed core/distribution configuration. This eliminates the need for Spanning Tree Protocol (STP) across the campus network by providing multihoming capabilities from the access to the distribution layer, while distribution to the core is an L3 IP fabric. ESI-LAG also supports horizontal scaling with more than two devices in the distribution layer and can extend EVPN to the core.

Figure 2: QFX5110 switch as a campus collapsed core/distribution switch with EVPN multihoming (ESI-LAG) and MC-LAG support

  • Campus Fabric Core-Distribution. A pair of interconnected QFX5110 switches can provide EVPN L2 and L3 VXLAN gateway support. This eliminates the need for STP across the campus network by providing a multihoming capability from the access to the distribution layer, while distribution to the core is an L3 IP fabric using EVPN technology. The IP fabric can also extend to connect multiple enterprise buildings, while VXLAN allows stretching L2 across buildings. An IP Clos network between the distribution and the core layers can exist in two modes, both of which are supported by the QFX5110 switch:
    • Centrally routed bridging overlay: An IRB interface placed at a central location in the fabric (in this case, a core device)
    • Edge routed bridging overlay: An IRB interface placed at the edge of the fabric (in this case, a distribution device)
  • Campus Fabric IP Clos: The campus fabric IP Clos architecture pushes VXLAN Layer 2/3 gateway functionality to the access layer. In this architecture, the QFX5110 switch acts as an IP fabric distribution switch.

Features and Benefits

  • Automation—The QFX5110 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 supports integration with VMware NSX Layer 2 Gateway Services, and OpenStack.
  • Flexible Forwarding Table—The QFX5110 includes a Unified Forwarding Table (UFT), which 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 QFX5110 supports 288,000 MAC addresses. In Layer 3 mode, the table can support 208,000 host entries. In LPM mode, it can support 128,000 prefixes. Junos OS provides configurable options through a CLI so that each QFX5110 can be optimized for different deployment scenarios.
  • Intelligent Buffer Management—The QFX5110 switches have a total of 16 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 QFX5110 effectively absorbs traffic bursts while providing deterministic performance, significantly increasing performance over static allocation.
  • MPLS—QFX5110 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. This enables the QFX5110 to be deployed as a low-latency MPLS label-switching router (LSR).
  • VXLAN Overlays—The QFX5110 switch is capable of supporting Layer 2 and Layer 3 gateway services. Customers can deploy overlay networks to provide Layer 2 adjacencies for applications over Layer 3 fabrics. The overlay networks utilize VXLAN in the data plane and EVPN or OVSDB to program the overlays. The overlays can operate without a controller, or they can be orchestrated with an SDN controller.
