In immersion cooling, what does the term 'single-phase' refer to?

The server operates on a single power phase

The coolant changes from liquid to gas and back to liquid

The coolant remains in a liquid state throughout the cooling process

Only one server is cooled at a time

A system administrator is monitoring a PowerEdge server and notices that the inlet temperature is within the normal range, but the CPU temperature is higher than expected. The server is air-cooled. What is the most likely cause?

Dust accumulation on the CPU heatsink

The server's fans are set to a low speed

The server is in a low-power state

The ambient temperature is too low

A data center is planning to deploy a mix of PowerEdge servers with air cooling and direct liquid cooling (DLC) in the same rack. What is the most important consideration to ensure proper cooling?

Disable the thermal monitoring on air-cooled servers

Place DLC servers at the bottom of the rack

Use the same fan speed settings for all servers

Ensure that the airflow direction is consistent for all servers

A data center is deploying PowerEdge servers with direct liquid cooling (DLC). The facility's water supply has a high mineral content. What should the administrator do to prevent damage to the cooling system?

Use the facility water directly without treatment

Use a coolant distribution unit (CDU) with a deionization filter

A system administrator notices that a PowerEdge server's fans are running at a constant high speed, even when the server is idle. The server is in a properly ventilated rack. What should the administrator check first?

The server's power supply status

The server's thermal sensor readings in iDRAC

The server's network configuration
