Statement of Volatility – Dell EMC Power Edge T150 Dell EMC Power Edge T150 contains both volatile and non-volatile (NV) components. Volatile components lose their data immediately upon removal of power from the component. Non-volatile components continue to retain their data even after the power has been removed from the component. Components chosen as user- definable configuration options (those not soldered to the motherboard) are not included in the Statement of Volatility. Configuration option information (pertinent to options such as microprocessors, remote access controllers, and storage controllers) is available by component separately. The following NV components are present in the Power Edge T150 server.

Frequently Asked Questions
Which components retain data after power loss?
Non-volatile (NV) components like BIOS SPI Flash, iDRAC EMMC, and CPU Vcore are designed to retain data after power removal.
Does the operating system write data to all memory types?
No. The BIOS Data ROM, iDRAC EMMC, và several EEPROM components do not have the operating system writing data to them during normal operation.
Can I manually clear or update any component's firmware?
Some flash memories like BIOS SPI Flash can be programmed via firmware update process; others are protected and cannot be cleared by users.
What is the type of memory used for BIOS system configuration settings?
The type of memory used for storing general BIOS setting information is PCH Internal CMOS RAM, which is listed as battery-backed.
