H8B50A Use Case
High-Density Data Center Rack Power Management
In a hyperscale data center hosting GPU-accelerated AI workloads, IT operations deploy the H8B50A-HPE Metered Switched 4.9kVA PDU vertically across dense 42U racks. Real-time per-outlet metering and remote on/off control enables automated load balancing, preventing circuit overloads and optimizing rack power allocation. Benefit: Maximizes uptime, reduces PDU tripping risk and lowers cooling costs through precise energy management.
Colocation Facility Remote Reboot & SLA Compliance
A colocation provider offers customers isolated power feeds using the H8B50A-HPE Metered Switched 24A/208V PDU with C13 and C19 outlets. Tenants access a secure web console to monitor consumption per device and perform remote power cycles on locked-down circuits. Benefit: Accelerates mean time to repair (MTTR), ensures SLA-driven availability and enhances transparent billing with accurate client-level metering.
Edge Computing Site Load Forecasting and Energy Efficiency
A regional financial trading firm installs the vertical-mount H8B50A-HPE PDU at distributed edge nodes to power low-latency servers. Integrated metering data feeds into capacity-planning tools, enabling seasonal load forecasting and automatic shutdown of non-critical gear during off-peak hours. Benefit: Improves energy efficiency by up to 20%, supports proactive capacity expansion and maintains regulatory compliance on power usage reporting.
