Summary
Rising inlet air temperatures cause thermal stress in data centers. This study proposes an inlet temperature sensitivity analysis and server relocation algorithm to minimize hotspots and hardware failures.
Area of Science:
- Data center thermal management
- Computer hardware reliability
- Computational fluid dynamics
Background:
- Elevated inlet air temperatures reduce heat dissipation in air-cooled servers.
- This leads to thermal stress, hotspots, and potential hardware failure in data centers.
- Server failures result in performance degradation, financial losses, and increased energy consumption for cooling.
Purpose of the Study:
- To profile inlet temperature sensitivity (ITS) for air-cooled servers.
- To determine optimal server locations to mitigate thermal hotspots and stress.
- To propose a novel algorithm for thermal state monitoring and server relocation.
Main Methods:
- Profiling of inlet temperature sensitivity (ITS) for servers.
- Development of a server relocation algorithm based on ITS analysis.
- Implementation of a thermal state monitoring system.
Main Results:
- Relocated servers' peak outlet temperatures were brought closer to the average outlet temperature by over 5 times.
- The average peak outlet temperature was reduced by 3.5%.
- Overall thermal stress within the data center was minimized.
Conclusions:
- The proposed ITS analysis and server relocation algorithm effectively reduce thermal stress.
- Optimizing server placement is crucial for preventing hotspots and hardware failures.
- This approach enhances data center reliability and energy efficiency.

5.2K
A thermodynamic process that occurs at constant temperature is called an isothermal process. Heat slowly flows into the system or out of the system to maintain thermal equilibrium. Processes involving phase changes like water evaporation into steam or freezing water into ice at a constant temperature are examples of Isothermal Processes.
An ideal gas can also undergo isothermal expansion or compression.
For example, consider 1 mole of an ideal gas inside an isolated cylinder at initial volume V...

01:09Thermal Stress
3.4K
If the temperature of an object is changed while it is prevented from expanding or contracting, the object is subjected to stress. The stress is compressive if the object expands in the absence of constraint and tensile if it contracts. This stress resulting from temperature change is known as thermal stress. It can be quite large and can cause damage. To avoid this stress, engineers may design components so they can expand and contract freely. For instance, on highways, gaps are deliberately...

2.2K
San Francisco's Golden Gate Bridge is exposed to temperatures ranging from -15 °C to 40 °C. At its coldest, the main span of the bridge is 1275 m long. Assuming that the bridge is made entirely of steel, what is the change in its length between these temperatures?
To solve the problem, first, identify the known and unknown quantities. The initial length (L) of the bridge is 1275 m, the coefficient of linear expansion (α) for steel is 12 x 10-6/°C, and the change in temperature (ΔT) is 55...

Distributed loads are a common type of load that engineers and scientists encounter in various practical situations. Distributed loads often refer to a type of load spread over a surface or a structure and can be modeled as continuous force per unit area.
For example, consider a bookshelf filled with books stacked vertically adjacent to each other. The weight of the books is evenly distributed over the length of the shelf. As a result, the pressure at different locations on the surface of the...

2.1K
Understanding heat transfer mechanisms is essential for understanding how our bodies maintain balance in different environmental conditions. When the environment is thermoneutral, the body is in a state of balance, neither using nor releasing energy to maintain its core temperature. However, when the environment is not thermoneutral, the body employs four heat transfer mechanisms to maintain homeostasis: conduction, convection, evaporation, and radiation. These mechanisms facilitate heat...

A thermometer measures body temperature. The common sites for measuring body temperature are the oral cavity, axillary region, temporal artery, and skin surface, such as the forehead, abdomen, and axilla. True core body temperature is assessed in the rectum, tympanic membrane, pulmonary artery, esophagus, and urinary bladder.
