CompTIA Server+ (SK0-005)Server Hardware Installation and ManagementEasy
A data center manager is planning to deploy a new rack of servers. To ensure efficient cooling, they want to prevent hot air from recirculating back into the cold aisles. Which of the following physical components would be MOST effective for filling unused spaces in the server racks to achieve this goal?
- ABlanking panels
- BSide panels
- CRack shelves
- DCable management arms
Show answer & explanationAnswer & explanation
Correct answer: A. Blanking panels
Blanking panels are specifically designed to fill unused rack unit (U) spaces in server racks. By blocking these openings, they prevent hot exhaust air from the rear of the rack from recirculating through the rack's interior and mixing with cold intake air in the front, thereby improving cooling efficiency and preventing hot spots.
Why the other options are wrong
- B. Side panels cover the sides of the entire rack but don't address individual unused rack unit spaces within the rack.
- C. Rack shelves hold equipment but are not designed to seal empty spaces for airflow management.
- D. Cable management arms organize cables but don't block airflow in unused rack spaces.
Blanking Panel
A component used to fill unused rack unit spaces in a server rack, preventing hot air recirculation and improving cooling efficiency by directing airflow.
- Fills empty rack U spaces
- Prevents hot/cold air mixing
- Improves cooling efficiency
Memory trick: Blanking panels block, cables manage the flock, side panels cover, front doors discover.
