Statement of Volatility – Dell EMC DSS8440

The Statement of Volatility provides you information related to volatile and non-volatile components of different

configurations of Dell EMC DSS servers.

Volatile components lose their data when the system is powered off and disconnected from the electrical outlet,

whereas, non-volatile components continue to retain their data even when the system is powered off.

The following table provides information of the different configurations of the DELL EMC DSS8440 server.
