JH402A Use Case
Hyperscale Data Center Leaf-Spine Deployment
In a multi‐tenant cloud environment requiring high-density 25/100GbE connectivity, IT architects deploy the JH402A-HPE FlexFabric 5950 48SFP28 8QSFP28 Switch as leaf switches in a spine-leaf fabric. This configuration delivers sub-microsecond latency, automated provisioning via HPE Intelligent Resilient Fabric (IRF), and up to 3.2Tbps of switching capacity. The outcome is predictable east-west traffic performance, simplified operations with single-pane management, and a 40% reduction in network bottlenecks, accelerating VM provisioning and tenant onboarding.
Enterprise Campus Core and Aggregation Switch
A global financial services firm modernizes its campus network by replacing legacy 10GbE switches with the JH402A-HPE FlexFabric 5950 48SFP28 8QSFP28 Switch at the core and aggregation layers. Leveraging 48 native 25GbE ports and 8 uplinks at 100GbE, the switch supports bandwidth-intensive applications like video conferencing, VoIP and real‐time analytics. Benefits include consistent application performance, seamless QoS enforcement, and 50% lower power consumption per port, ensuring predictable SLAs and future-proof scalability for 10,000+ users.
High-Performance Computing Cluster Interconnect
A research university deploys the JH402A-HPE FlexFabric 5950 48SFP28 8QSFP28 Switch to interconnect GPU‐accelerated HPC nodes for AI training and large-scale simulations. The switch’s low-latency, high-density architecture and RDMA-capable fabric enable 100GbE MPI traffic with sub-microsecond jitter. As a result, compute throughput increases by 35%, job completion times drop by 20%, and researchers gain flexible bandwidth allocation and simplified fabric management, accelerating scientific breakthroughs in genomics and climate modeling.
