Statement of Volatility – Dell EMC PowerEdge R750xa Owner's Manual
Summary
This is the Statement of Volatility for the Dell EMC PowerEdge R750XA server, documenting all volatile and non-volatile memory components. It details component types, quantities, reference designators, sizes, and data retention characteristics for items including BIOS flash, iDRAC flash, BMC eMMC, system memory, CPLD RAM, and storage controller components. The document is essential for security professionals, government agencies, and organizations requiring memory sanitization procedures and data security compliance.

Statement of Volatility – Dell EMC Power Edge R750XA Dell EMC Power Edge R750XA 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 R750XA server.

Frequently Asked Questions
What components retain data when power is removed?
Non-volatile components, such as BIOS SPI Flash, iDRAC SPI Flash, and BMC EMMC, retain data even after power is removed.
Is the system memory volatile?
Yes, system memory is volatile and loses data immediately upon removal of power.
What is the purpose of the BIOS SPI Flash?
It stores boot code, system configuration information, and UEFI firmware.
Can the iDRAC SPI Flash be updated by the host processor?
No, iDRAC may issue a clear command to erase contents, but there is no mechanism for the host to write to the SPI NOR.
