Statement of Volatility – Dell PowerEdge R720 and

R720XD

Dell PowerEdge R720 and R720XD contain 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 PowerEdge R720 and R720XD servers.

Item How is this memory write protected? How is the memory cleared? ONFI Backup Flash Not WP. Not visible to Host Processor Flash can be cleared by powering up the card and allowing the controller to flush the contents to VDs. If the VDs are no longer available, cache can be cleared by going into controller bios and selecting Discard Preserved Cache. SDRAM Not WP. Not visible to Host Processor Cache can be cleared by powering off the card NVSRAM Not WP.
