Statement of Volatility – Dell EMC PowerEdge MX7000
This Statement of Volatility provides the information related to volatile and non-volatile components within the Dell EMC PowerEdge MX7000 Infrastructure. Volatile components lose
their data when power has been removed from the system, whereas, non-volatile components continue to retain their data when the power has been removed.
The following table provides volatility information for the various modules within the MX7000. For volatility information on compute sleds and other I/O modules, see documentation
specific to those modules.
