Statement of Volatility

–

Dell DR4100

and DR6000

Dell DR4100 and DR6000 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. Components chosen

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 Dell DR4100 and DR6000 systems

. Note that the Dell DR6000 system will always have a

WAM 2

NVRAM card; whereas, the DR 4100 may have a

WAM 1

or a

WAM 2

card installed.
