Description

The QFX5250-64OE-L is a data centre switch engineered for next-generation AI infrastructure, delivering 64 x 1.6Tbps OSFP ports and 102.4Tbps total switching throughput in a fixed 2U form factor. Liquid-cooled with Integrated ORv3 (Open Rack v3) power shelf support, it is purpose-built for hyperscale AI training, inference, and storage cluster environments where power efficiency and thermal management are critical. Ultra Ethernet Transport (UET) ready and running Junos OS Evolved, it provides AI-optimised congestion avoidance for lossless fabric operation.

The QFX5250-64OE-L supports EVPN-VXLAN, IP fabric, RoCEv2, and NVMe storage networking, enabling end-to-end multivendor intent-based AI networking across the data centre. Front-to-back (port-side intake) airflow and DC power supply suit modern open-rack deployments. Visit iptrading.com.au to secure your order — enterprise-grade hardware with expert support.

FAQs

Q: What makes the QFX5250-64OE-L suitable for AI data centre deployments?
A: The QFX5250-64OE-L is purpose-built for AI workloads, offering 64 x 1.6Tbps OSFP ports, 102.4Tbps total throughput, liquid cooling, and Junos OS Evolved with advanced congestion avoidance. It supports Ultra Ethernet Transport (UET), RoCEv2, and lossless fabric operation — all critical for AI training, inference, and high-performance storage cluster environments.

Q: What is Integrated ORv3 support on the QFX5250-64OE-L?
A: ORv3 (Open Rack v3) is an open standards-based power shelf architecture used in hyperscale data centres. The QFX5250-64OE-L integrates natively with ORv3 power infrastructure, simplifying deployment in open-rack environments and improving overall power efficiency.

Q: Does the QFX5250-64OE-L support multivendor environments?
A: Yes. The QFX5250-64OE-L supports end-to-end multivendor intent-based AI networking. Its standards-based protocols including EVPN-VXLAN, IP fabric, and Ultra Ethernet Transport ensure interoperability across heterogeneous data centre environments.

Q: What storage networking protocols does this switch support?
A: The QFX5250-64OE-L supports RoCEv2 (RDMA over Converged Ethernet) and NVMe over Fabrics, making it well-suited for high-performance storage networking alongside AI compute clusters.

Q: Can I purchase the Juniper QFX5250-64OE-L in Australia through IP Trading?
A: Yes. IP Trading (iptrading.com.au) is an Australian B2B IT hardware reseller stocking enterprise Juniper networking equipment including the QFX5250 series. Contact us for pricing, availability, and expert pre-sales support tailored to your AI data centre requirements.

Q: What is the difference between the QFX5250-64OE-L and standard QFX5250 variants?
A: The QFX5250-64OE-L is the liquid-cooled variant with Integrated ORv3 support and DC power, designed specifically for hyperscale open-rack AI data centres. Standard QFX5250 variants typically use conventional air cooling and may differ in power supply and rack integration options.
