Statement of Volatility – Dell EMC Power Edge R440 Dell EMC Power Edge R440 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 R440 server.

Frequently Asked Questions
What types of components lose or retain data when power is removed?
Volatile components lose their data immediately upon removal of power, while non-volatile components retain their data.
Which components store the server's BIOS and network login credentials?
The Primary BIOS SPI Flash (U_PRIM_SPI_BIOS) stores core boot information and configuration settings. The iDRAC and BMC EMMC are also listed as Non-Volatile storage.
Can a user directly write new data to all onboard memory components?
No. Components like BIOS Recovery, iDRAC, Memory VDDQ, CPU vcore, and many flash areas can only be updated through specific firmware or secure means.
How is the system's Trusted Platform Module (TPM) cleared or managed?
For TPM modules, a clear operation must typically be performed using the F2 Setup option on the operating system. For iDRAC/iDSDM, clearing methods depend if the device is in the physically removed or host domain.
