JH394A Use Case
Hyperscale Data Center Leaf-Spine Fabric with HPE FlexFabric 5940
In a cloud provider’s data center, the JH394A-HPE FlexFabric 5940 48XGT 6QSFP+ Switch serves as a leaf node in a spine-leaf architecture. It delivers 48 ports of 10/25G server connectivity and six 40/100G uplinks to spine switches, reducing east-west latency by 30% and supporting 2:1 oversubscription. Integrated with HPE Fabric Composer, it enables automated provisioning and high-performance hybrid cloud services for rapid workload scaling.
Enterprise Campus Core Network Modernization
A multinational enterprise consolidates its campus core with the JH394A-HPE FlexFabric 5940 to support cloud applications and IoT growth. The switch aggregates 48 high-density 25G-ready access links and six 100G uplinks across buildings, quadrupling bandwidth capacity. With sub-50ms MLAG failover and centralized analytics via HPE Intelligent Management Center, it boosts network resilience and operational efficiency.
High-Performance AI/ML Training Cluster Interconnect
An AI research lab deploys the JH394A-HPE FlexFabric 5940 as the central fabric for GPU training clusters. Servers connect over 25G ports while six QSFP+ interfaces provide 100G trunks for distributed compute nodes, achieving 200Gbps bisection bandwidth and under-1µs inter-node latency. Built-in telemetry with HPE InfoSight delivers proactive monitoring, reducing training time by 40% and optimizing resource utilization.
