Juniper targets data center networks with flexible 400G switch


Juniper has deployed a flexible switch that can be upgraded to support 400GbE networks and includes tight integration with the company’s Apstra Intent-Based Networking (IBN) software.

The Juniper QFX5700, a 5U, eight-slot, 25.6 Tbps speed enclosure supports a range of line cards that customers can mix and match at Ethernet speeds from 10G to 400G to meet application needs or migration.

The QFX 5700 is built with Broadcom’s Trident 4 chipset and runs Junos OS Evolved, the vendor’s native Linux-based network operating system.

The QFX5700 is intended for data centers where capacity and cloud services are added, said Mike Bushong, vice president of cloud-ready data center at Juniper. The switch has a variety of port speeds for spine, leaf, interconnect and campus use cases, with the ability to connect a mix of device types and profiles, said Bushong.

While the need for full 400G in corporate networks is not currently widespread, it is increasing, experts say.

“We are seeing companies accelerate their adoption of 400G technology as an integral part of their strategy to sustain their networks for three years or more. The main driver of this strategy is the growing adoption of AI / ML compute clusters that require 50 / 100G I / O combined with 400G scaling, ”according to a recent report from researchers at Futurum.

“These capabilities are essential for businesses to meet their top priority of improving visibility of application flow levels on their networks. Businesses are demanding that their data centers be more application sensitive, especially in hybrid cloud settings, to advance their IBN goals, particularly by enabling proactive monitoring and automating troubleshooting to improve QoE metrics. ‘experience) of their applications,’ Futurum said. .

While hardware capacity and flexibility are history, the switch can be used to work with Juniper’s IBN software, Apstra, which it purchased last December.

Junos Evolved can work with Apstra software but is not a prerequisite as Apstra software is hardware independent and therefore can be integrated to work with Cisco, Arista, Dell, Microsoft and Nvidia / Cumulus products.

Apstra maintains a real-time repository of configuration, telemetry, and validation information to ensure the network is doing what customers want it to do. Apstra also includes automation features to provide consistent network and security policies for workloads across physical and virtual infrastructures.

Juniper recently released Apstra 4.0 which makes it easy to add devices or workloads. The system ensures that they operate across the entire network structure without manual intervention required in the past. It also includes customizable and reusable network templates.

“Apstra continually models the state of the network, verifies this state, collects rich telemetry and proactively alerts human operators when a problem may arise,” said Bushong.

Apstra models can help create frameworks of operations, often in multi-vendor environments, and in a repeatable way that can identify when a task should be called, how it should best be performed, and whether it achieved the intent. desired, said Bushong.

“Add that to the QFX5700, and customers can extend that intelligence to more places, in more ways, to meet a broader set of use cases,” he said.

The QFX5700 will be available in the fourth quarter.
