QFX5220 Switch Datasheet

The QFX5220 includes the following capabilities. Please refer to the Specifications section for current shipping features.

The QFX5220-32CD offers 32 ports in a 1 U form factor. The high-speed ports support a variety of configurations, including 100GbE and 400GbE.

For a complete list of features, refer to the Specifications section below and Feature Explorer.

The QFX5220 switches are optimized for high-density fabric deployments. The QFX5220-32CD provides an option of either 32 ports of 400GbE, 100GbE, or 40GbE, while the QFX5220-128C provides an option of either 128 QSFP28 100GbE ports or 128 40GbE QSFP ports.

The QFX5220 offers a choice of interface speeds for server and intra-fabric connectivity, providing deployment versatility and investment protection.

• Rich automation capabilities: The QFX5220 switches support a number of network automation features for plug-and-play operations, including zero-touch provisioning (ZTP), operations and event scripts, automatic rollback, and Python scripting.
• Advanced Junos Evolved features: The QFX5220 switch supports features such as BGP add-path, MPLS, L3 VPN, RoCEv2, and multicast capabilities.
• Junos Evolved software architecture: The QFX5220 supports a modular Junos Evolved software architecture that allows the switch’s control and data plane processes and functions to run in parallel, maximizing utilization of the high-performance quad-core CPU, support for seamless component upgrade without bringing the switch down, and support for containerization, enabling application deployment using LXC or Docker.

   

The QFX5220-32CD can be deployed as a universal device in cloud data centers to support 100GbE server access and 400GbE spine-and-leaf configurations, optimizing data center operations by using a single device across multiple layers of the network (see Figure 1).

The QFX5220-128C is a high-radix 100GbE lean-spine switch optimized to aggregate 10GbE and 25GbE top-of-rack switches in these environments. Many cloud, service provider, data center, and enterprise networks are deploying 100GbE to handle growing demand. Figure 2 and Figure 3 show multiple use cases with the QFX5220-128C as a lean spine.

Data center fabric management: Juniper^® Apstra provides operators with the power of intent-based network design to help ensure changes required to enable data center services can be delivered rapidly, accurately, and consistently. Operators can further benefit from the built-in assurance and analytics capabilities to resolve Day 2 operations issues quickly.

Apstra key features are:

• Automated deployment and zero-touch deployment
• Continuous fabric validation
• Fabric life-cycle management
• Troubleshooting using advanced telemetry

For more information on Apstra, see Juniper Apstra.

• Automation and programmability: The QFX5220 supports numerous network automation features, including operations and event scripts and ZTP.
• Cloud-level scale and performance: The QFX5220 supports best‑in‑class cloud‑scale L2/L3 deployments with a low latency of 660 ns (cut‑through) for the QFX5220‑32CD, 1070 ns (cut‑through) for the QFX5220‑128C, and with a superior scale and performance. Junos Evolved provides configurable options through a CLI, enabling each QFX5220 to be optimized for different deployment scenarios.

• MPLS: The QFX5220 supports a broad set of MPLS features, including L3 VPN, RSVP traffic engineering, and LDP to support standards-based multitenancy and network virtualization with per-flow service-level agreements (SLAs) at scale. The QFX5220 can also be deployed as a low-latency MPLS label-switching router (LSR) or MPLS provider edge (PE) router in smaller scale environments. The QFX5220, along with Juniper Networks QFX5100 and QFX5200 switches, are the most compact, low-latency, high-density, low-power family of switches to offer an MPLS feature set in the industry.
• RoCEv2: As a switch capable of transporting data as well as storage traffic over Ethernet, the QFX5220 provides an IEEE data center bridging (DCB) converged network between servers with disaggregated flash storage arrays or an NVMe-enabled storage area network (SAN). The QFX5220 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. The RDMA over Converged Ethernet version 2 (RoCEv2) transit switch functionality, including priority-based flow control (PFC) and Data Center Bridging Capability Exchange (DCBX), are included as part of the default software.
• Junos OS Evolved: Junos Evolved is a native Linux operating system that incorporates a modular design of independent functional components and enables individual components to be upgraded independently while the system remains operational. Component failures are localized to the specific component involved and can be corrected by upgrading and restarting that specific component without having to bring down the entire device.
• Retained state: State is the retained information or status pertaining to physical and logical entities. It includes both operational and configuration state, comprising committed configuration, interface state, routes, hardware state, and what is held in a central database called the distributed data store (DDS). State information remains persistent, is shared across the system, and is supplied during restarts.
• Feature support: All key networking functions such as routing, bridging, management software, and management plane interfaces, as well as APIs such as CLI, NETCONF, Juniper Extension Toolkit (JET), Junos Telemetry Interface (JTI), and the underlying data models, resemble those supported by Junos. This ensures compatibility and eases the transition to Junos Evolved.
  
  

The QFX5220 supports JTI, a modern telemetry streaming tool that provides performance monitoring in complex, dynamic data centers.
