QFX5110 access and aggregation switches deliver low latency, rich Layer 2 and Layer 3 features, VXLAN overlay deployments, and 100GbE uplinks, making it the industry's most nimble line of switches. Featuring L3 gateway capabilities for bridging between virtualized and bare-metal servers, the QFX5110 is designed for extremely agile data centers that demand support for overlay/underlay network architectures. The highdensity 10GbE, 40GbE, and 100GbE ports also make the QFX5110 ideally suited for use in spine and leaf topologies.

Product Description

Data centers are rapidly adopting cloud services, whether completely off-premise models or hybrid models with critical services offered through on-premise private clouds. The tremendous growth of off-premise cloud services, coupled with the widespread adoption of overlay technologies, has created a need for highly agile switching platforms that can satisfy the demands of these evolving data centers. The high-performance Juniper Networks® QFX5110 line of Ethernet switches fit the bill, providing the foundation for dynamic data centers. As a critical enabler for IT transformation, the data center network supports cloud and SDN adoption, network virtualization, integrated/scale-out storage, and the rapid deployment and delivery of mission-critical applications that significantly increase east-west traffic within the data center. Furthermore, increasing demand for 100GbE spine ports is driving the need for 100GbE uplinks for all server access speeds, including 10GbE and 40GbE. The QFX5110 includes 100GbE uplinks, enabling it to support a diverse set of switching architectures, including fabric, Layer 3, and spine-and-leaf deployments, enabling users to easily adapt as requirements change over time.

Architecture and Key Components

The QFX5110 switches include 10GbE (fiber) and 40GbE or 100GbE fixed-configuration options with rich Layer 2, Layer 3, and MPLS features. The QFX5110 switches run the same reliable, high-performance Juniper Networks Junos® operating system that is used by the Juniper Networks QFX5100 family of products, EX Series Ethernet Switches, Juniper Networks routers, and Juniper Networks SRX Series Services Gateways, ensuring a consistent implementation and operation of control plane features across the entire Juniper infrastructure.

QFX5110 Switch Models

The QFX5110 switches are compact, 1 U platforms that provide wire-speed packet performance, very low latency, and a rich set of Junos OS features. In addition to a highthroughput Packet Forwarding Engine (PFE), the performance of the QFX5110 control plane is further enhanced with a powerful 1.8 GHz quad-core Intel CPU with 16 GB of memory and 64 GB SSD storage.

The QFX5220-32CD offers 32 ports of 400-Gigabit Ethernet in a low-profile 1-U form factor. With 12.8-Tbps bandwidth, the QFX5220-32CD is optimally designed for spine-and-leaf deployments in enterprise, service provider, and cloud data centers. The high-speed ports support a wide variety of port configurations that include speeds of 400 Gbps, 100 Gbps, 25 Gbps, 40 Gbps, and 10 Gbps.

An Intel Xeon D-1500 processor drives the QFX5220 control plane, which runs the Junos OS Evolved software. The Junos OS Evolved software image is stored on two internal 50-GB solid-state drives (SSDs).

The Juniper Networks® QFX5700 Switch is a next-generation, modular and fabric-less spine-and-leaf switch that offers flexibility, cost efficiency with lower-per-bit, high-density 400GbE, 200GbE, 100GbE, 50GbE, 40GbE, 25GbE, and 10GbE interfaces for server and intra-fabric connectivity.

A versatile, future-proven solution for today's data centers, the QFX5700 leverages the power of a fully programmable Broadcom's Trident 4 chipset to support and deliver a diverse set of use cases. It supports advanced Layer 2, Layer 3, and Ethernet VPN (EVPN)- Virtual Extensible LAN (VXLAN) features. For large public cloud providers-early adopters of high-performance servers to meet explosive workload growth-the QFX5700 supports very large, dense, and fast 400GbE IP fabrics based on proven Internet scale technology. For enterprise customers seeking investment protection as they transition their server farms from 10GbE to 25GbE, the QFX5700 switch also provides a high radix-native 100GbE/400GbE EVPN-VXLAN spine option at reduced power and a smaller footprint.

The QFX5700 supports diverse use cases such as Data Center Fabric Spine, EVPN-VXLAN Fabric, Data Center Interconnect/Border, Secure DCI, multi-tier campus, campus IP fabric, and connecting firewall clusters in the DC to the fabric. Delivering 25.6 Tbps of bidirectional bandwidth, the switch is optimally designed for spine-and-leaf deployments in enterprise, high-performance computing (HPC), service provider, and cloud data centers.

The QFX5700 is a modular merchant silicon-based chassis offering a wide variety of ports configurations, including 400GbE, 200GbE, 100GbE, 50GbE, 40GbE, 25GbE, and 10GbE. The QFX5700 is equipped with up to four AC or DC power supplies, providing N +N feed redundancy or N+1 PSU redundancy when all power supplies are present. Two hot-swappable fan trays offer front-to-back (AFO) airflow, providing N+1 fan rotor redundancy at Chassis. The platform also includes support for in-line MACsec line cards.

The QFX5700 includes an Intel Hewitt Lake 6 core to drive the control plane, which runs the Junos® OS Evolved operating system software.

Two QFX5110 switch models are available:

• QFX5110-48S-A 10GbE/100GbE data center access switch, the QFX5110-48S offers 48 small form-factor pluggable plus (SFP+) transceiver ports and four QSFP28 ports that can be configured as 4x40GbE or 4x100GbE ports, with an aggregate throughput of 1.76 Tbps or 1.32 Bpps per switch. For added flexibility, each QSFP28 port can also be configured as 4x10GbE ports using breakout cables, increasing the total number of supported 10GbE ports to 64 per switch.

The Switch Control Board (SCBE2) serves the carrier Ethernet services router and carrier Ethernet transport markets that require higher-capacity traffic support, demanding greater interface density (slot and capacity scale) as well as improved services. The upgraded SCB is supported on MX960, MX480, and MX240 routers. Some key attributes of the SCBE2 are:

• A bandwidth of up to 340 Gbps per slot with redundant fabric support and 480 Gbps per slot without redundancy, and improved fabric performance on account of using the next-generation fabric (XF2) chip.
• A central clocking module and a centralized clocking architecture that support clock cleanup and distribution. The Stratum 3 clock module performs clock monitoring, filtering, and holdover at a centralized chassis location.
• Full performance with fabric redundancy for higher-capacity line cards such as MPC4.
• Support for MPC line cards only.
• Two 10-Gigabit Ethernet SFP+ ports. SFP+ port 0 can be used to connect an external device as a Router Reflector. SFP+ port 1 is unused.
• Support for cross-coupling of clock input (which requires an enhanced midplane: CHAS-BP3-MX960-S). You can configure the system such that one SCBE2 supports a GPS interface, and the other SCBE2 supports a BITS interface.
