826691-B21 Use Case
Optimize Thermal Management in High-Density Racks with 826691-B21-DL380 GEN10 BOX1/2 CAGE BKPLN KIT PL=SY
In enterprise data centers running large clusters of HPE ProLiant DL380 Gen10 servers, technicians install the 826691-B21 half-height cage blanking kit to seal unused slots and enforce front-to-back airflow. This targeted airflow control lowers inlet temperatures by up to 5 °C, aligns with ASHRAE TC 9.9 guidelines, and reduces cooling energy costs by 12%, extending server lifespan and cutting TCO.
Ensure Consistent Airflow and 99.99% Uptime in Virtualization Clusters with 826691-B21-DL380 GEN10 BOX1/2 CAGE BKPLN KIT PL=SY
In VMware and Hyper-V environments, IT teams fit the 826691-B21 blanking panels into empty I/O bays of DL380 Gen10 servers to eliminate recirculation paths. The precise slot coverage stabilizes internal airflow, prevents thermal throttling under peak loads, and sustains 99.99% application uptime, reducing maintenance overhead by 30% annually.
Enhance Edge Site Reliability and Dust Protection with 826691-B21-DL380 GEN10 BOX1/2 CAGE BKPLN KIT PL=SY
For remote and edge computing—such as retail kiosks, telecom shelters, and branch offices—engineers deploy the 826691-B21 blanking kit in ProLiant DL380 Gen10 servers to block dust, debris, and unregulated airflow. This preventive measure maintains stable operating temperatures in variable environments, cuts unplanned service calls by 40%, and ensures continuous data processing for IoT and real-time analytics.
