An administrator notices that servers mounted in the middle of several server rack rows are experiencing thermal warnings during peak utilization. Environmental monitoring reveals that cool supply air from raised floor vents is mixing directly with hot exhaust air from adjacent equipment rows prior to entering server intake fans. Which physical infrastructure design change should the network administrator implement to prevent this air mixing?
- AIncrease the operational speed of server chassis intake fans while maintaining single-direction rack orientation across all rows.
- Reorient the equipment racks into alternating rows so server intakes face intake aisles and exhausts face exhaust aisles to create hot and cold aisles.Cevap
- CInstall high-velocity inline exhaust fans on individual server chassis to push warm air directly toward room perimeter walls.
- DLower the central HVAC supply temperature below local dew point thresholds to force cold air through mixing zones rapidly.
Cevap
Reorient the equipment racks into alternating rows so server intakes face intake aisles and exhausts face exhaust aisles to create hot and cold aisles.
Arranging rack equipment into alternating hot and cold aisles physically isolates cold intake streams from hot exhaust air streams. Cold supply air enters the cold aisles to feed server intake fans, while rear server exhausts discharge heat into dedicated hot aisles for collection by environmental return ducts.
