Statement of Volatility – Dell PowerEdge R630

Dell PowerEdge R630 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

PowerEdge R630 server.

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.
