Product Overview

With the current growth in artificial intelligence (AI) and machine learning (ML) developments, networks are expected to perform at their best to support heavy workloads. Higher bandwidth requirements between the server and the top-of-rack switch result in higher 400GbE radix requirements at the spine and super-spine layer of the IP fabric multitier architecture.

Juniper Networks QFX5230-64CD switch supports:

— high-speed, high-density, spine-and-leaf IP fabrics

— 400GbE, 200GbE, 100GbE, 50GbE, 40GbE, 25GbE, and 10GbE connections

— advanced L2/L3 features and secure ZTP

— large, next-generation IP fabrics with best-in-class automation—capabilities

 

Product Description

Juniper Networks® QFX5230-64CD switch is a high-radix class switch, dedicated for high-bandwidth network switching devices supporting up to 64 × 400GbE, 128 × 200GbE, 256 × 100GbE, 64 × 40GbE, 256 × 25GbE, 256 × 10GbE ports in 2 U form factor. This makes the QFX5230-64CD optimal for AI data center deployments and spine and super-spine roles within IP and Ethernet VPN–Virtual Extensible LAN (EVPN-VXLAN) fabrics. The additional Remote Direct Memory Access over Converged Ethernet (RoCEv2) capabilities of the QFX5230-64CD support IP storage deployments where instead of relying on deep buffer switching, the QoS mechanisms such as priority-based flow control-distributed services code point (PFC-DSCP) and explicit congestion notification (ECN) deliver high performance for the storage workloads. Support for ZR/ZR-M optics makes it suitable for edge and data center interconnect (DCI) use cases.

 

Automation and Monitoring

Juniper® Apstra® intent-based networking delivers full Day 0 through Day 2+ capabilities for IP/EVPN fabrics with closed-loop assurance in the data center. Apstra is a fabric management solution that empowers organizations to automate and manage their networks across virtually any data center design, vendor, and topology, making private data center as easy as cloud. Apstra provides full Day 2+ operations assurance with multiple built-in intent-based analytics probes to assure your network is running as designed. In addition, Apstra provides a simple UI workflow to create custom intent-based analytics to capture, enrich, and visualize data from the managed devices. Apstra also provides the capability to capture and analyze flow data to provide complete network visibility.

For additional automation, Junos® OS Evolved supports a robust API set to support HashiCorp® Terraform®, Ansible, zero-touch provisioning (ZTP), operations and event scripts, automatic rollback, and Python scripts. The QFX5230-64CD supports Junos Telemetry Interface, a modern telemetry streaming tool that provides performance monitoring in complex, dynamic data centers.
