Statement of Volatility
The Dell™ PowerEdge™ M610 blade and its configurable modules contain 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. Dell PowerEdge blades may contain hard disk drives that retain
customer data after the system is powered off. Data should be removed from these hard disk drives
using locally approved methods before they are removed from a secured environment.
