JG219B Use Case
High-Density Top-of-Rack Aggregation for Private Cloud Virtualization
In a VMware- and KVM-powered private cloud, rack-level servers demand scalable 10GbE connectivity, EVPN-VXLAN overlay and sub-microsecond latency for live VM migrations. Deploying the JG219B-HPE FlexFabric 5820AF 24XG Switch at each Top-of-Rack consolidates up to 24×10Gb SFP+ host links with 4×40Gb QSFP+ uplinks, delivering 1.28Tbps non-blocking throughput and advanced L2/L3 services. Benefit: simplifies network segmentation, accelerates VM mobility by 30%, and reduces operational overhead through unified management and IPv4/IPv6 dual-stack routing.
Ultra-Low Latency Fabric for HPC and AI Workload Acceleration
Research clusters running GPU-intensive AI training and HPC simulations require deterministic latency and massive east-west bandwidth. The JG219B-HPE FlexFabric 5820AF 24XG Switch offers sub-600-ns cut-through switching across 24×10GbE SFP+ ports and 4×40GbE QSFP+ uplinks with QoS-prioritization. Outcome: maximizes GPU utilization, reduces model-training time by up to 20%, and scales seamlessly to thousands of nodes with industry-leading power efficiency and Fabric Composer integration.
Enterprise Campus Aggregation for High-Speed Wi-Fi 6 and IoT Connectivity
Modern enterprise campuses deploying Wi-Fi 6 access points, VoIP phones and IoT sensors require high-density 10Gb uplinks, MLAG for seamless failover and secure segmentation. Positioning the JG219B-HPE FlexFabric 5820AF 24XG at building distribution layers aggregates up to 24 AP links and 4 uplink trunks, while enforcing ACL-based micro-segmentation, VRF-Lite segmentation and dynamic ARP inspection. Benefit: ensures reliable high-throughput Wi-Fi 6 services, boosts application performance by 25%, and lowers TCO with HPE Intelligent Resilient Fabric automation.
