A company has had problems with their HVAC system being able to cool their datacenter as they have grown.
Which of the following could BEST be used to help reduce the load on the HVAC system?
Click on the arrows to vote for the correct answer
A. B. C. D.B.
The option that BEST helps to reduce the load on the HVAC system in a datacenter is B: Replacing traditional racks with water-cooled racks.
Explanation: A datacenter requires a consistent temperature and humidity level to ensure that the equipment operates correctly. The HVAC (Heating, Ventilation, and Air Conditioning) system is responsible for maintaining these environmental conditions within the datacenter. When a datacenter grows, the HVAC system may struggle to keep up with the increased heat load from the additional equipment, which can lead to equipment failures and downtime.
Option A: Replacing CAT5 cables with CAT6 cables would not directly reduce the load on the HVAC system. CAT6 cables are designed for higher speeds and reduced crosstalk, but this change would not reduce the heat generated by the servers.
Option C: Turning off non-critical application servers during non-business hours could reduce the heat generated by those servers, but it would not reduce the heat generated by the critical servers that must remain operational during non-business hours.
Option D: Removing the second power supplies from non-critical servers would not significantly reduce the heat generated by the servers, as the power supplies themselves do not generate significant amounts of heat.
Option B: Replacing traditional racks with water-cooled racks can significantly reduce the heat generated by the equipment. Water-cooled racks are designed to transfer the heat generated by the servers to a liquid cooling system that can be more efficiently cooled by the HVAC system. This approach can reduce the load on the HVAC system and improve the overall efficiency of the datacenter.
In conclusion, option B, replacing traditional racks with water-cooled racks, is the BEST option to help reduce the load on the HVAC system in a datacenter.
