517520-B21 Use Case
High-Performance Data Center Thermal Optimization
In a hyperscale data center running AI workloads on 40U HP BladeSystem enclosures, integrating the 517520-B21-HP BLc 6X Active Cool 200 FIO Fan Opt ensures consistent airflow at 200 CFM per chassis. This targeted solution maintains inlet temperatures below 25 °C under 90% CPU utilization, reduces hot-spot formation by 35%, and drives a 20% improvement in Power Usage Effectiveness (PUE), enabling 99.99% server uptime and predictable capacity expansion.
Cloud Service Provider Energy-Efficient Cooling Upgrade
When retrofitting a 10 MW cloud hosting facility, deploying the 517520-B21-HP BLc 6X Active Cool 200 FIO Fan Opt across over 1,000 HP ProLiant BLc servers delivered a 15% reduction in fan power draw and a 25% increase in heat-extraction capacity. This upgrade translated into $350 K annual OPEX savings, accelerated rack deployment cycles by 30%, and bolstered SLA compliance with sub-30 msec thermal response times.
Edge Computing Reliability in Harsh Environments
Telecom operators deploying micro-data centers at remote tower sites leverage the 517520-B21-HP BLc 6X Active Cool 200 FIO Fan Opt for sealed, dust-resistant cooling under extreme ambient conditions (−20 °C to 55 °C). The robust FIO bearings sustain 200 CFM airflow while cutting service‐call rates by 30% and extending Mean Time Between Failures (MTBF) by 40%, ensuring continuous 4G/5G packet processing and reduced field maintenance.
