Statement of Volatility – Dell PowerEdge R620

Dell PowerEdge R620 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 R620 server.

Item How is data input to this memory? How is this memory write protected? How is the memory cleared? PCH Internal CMOS RAM BIOS N/A – BIOS only control 1) Set NVRAM_CLR jumper to clear BIOS configuration settings at boot and reboot system; 2) AC power off system, remove coin cell battery for 30 seconds, replace battery and power back on; 3) restore default configuration in F2 system setup menu.

Power Supplies PSU FW Different vendors have different utilities and tools to load the data to memory. It can also be loaded by Dell Update Package from LC or OS (Windows and Linux) Protected by the embedded microcontroller. Special keys are used by special vendor provided utilities to unlock the ROM with various CRC checks during load.

ONFI Backup Flash FPGA backs up DDR data to this device in case of a power failure 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 ROC writes to this memory using it as cache for data IO to HDDs Not WP.
