Answers
D.
Allow for more efficient cooling
Suggested answer: D

Explanation:

Leaving one rack unit open at the bottom of a rack containing an XtremIO X2 is a practice recommended for allowing more efficient cooling. This space acts as a buffer zone, helping to facilitate better airflow and prevent the recirculation of hot air within the rack. It is a part of thermal management strategies in data centers to optimize the cooling systems, which are crucial for maintaining the performance and longevity of the equipment1.

The Dell Best Practices Guide for Rack Enclosures emphasizes the importance of proper cooling and airflow management within rack enclosures. It suggests that efficient cooling can help reduce inefficiencies at the rack level and is essential for maintaining the necessary thermal environment for rack-mounted equipment1. While the guide does not explicitly mention leaving a rack unit open at the bottom, the principle of optimizing airflow for cooling purposes is consistent with the practice.
