In a Dell EMC PowerEdge server, where are the system settings stored?

The correct answer is that the system settings in a Dell EMC PowerEdge server are stored in CMOS. CMOS stands for Complementary Metal-Oxide-Semiconductor, which is a technology used for constructing integrated circuits, including the memory used to store BIOS settings.

In the context of a server, CMOS memory retains the basic system configurations, such as hardware settings, time, and date information, even when the system is powered off. This is crucial for maintaining the functionality and configuration of the server upon boot-up.

While UEFI and BIOS are involved in system configuration and initialization, they rely on the underlying CMOS memory to store persistent settings across reboots. vFlash pertains to virtual flash storage for bootable images and doesn't relate to the storage of system settings. Hence, CMOS is the appropriate choice for storing the settings you need for a Dell EMC PowerEdge server.
