4. Statement of Volatility Dell PowerEdge T620 Dell PowerEdge T620 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 T620 server Item Non Quantity Reference Designator Size Volatile or Volitile Planer PCH Internal CMOS RAM Non Volatile U41 256 Bytes BIOS SPI Flash Non Volatile U49 1 8 MB iDRAC SPI Flash Non Volatile U16 1 4 MB BMC EMMC Non Volatile U2018 4 GB CPU Vcore and VSA Non Volatile PDU1 PAU1 4 25 KB Regulators System CPLD RAM Volatile U44 1 KB System Memory Volatile Up to 12 per DIMM lt 24 1 gt Up to 32GB per CPU DIMM Power Supplies PSU FW Non Volatile 1 per PSU Varies by part number Up to 2MB Varies by part number 16x2 5 Backplane Flash memory Non Volatile U_EXP_FLASH 1 32 Mb Expander FRU image Non Volatile U_EXP_EEPROM 512 Bytes BP FRU image Non Volatile U_BP_EEPROM 256 Bytes 8x3
