Appendix G.
Statement Of Volatility
This appendix describes the volatile and non-volatile components on the Intel® Server Board M10JNP2SB. It
is not the intention of this document to include any components not directly mounted to the server board,
including but not limited to: processors, memory, storage devices, or add-in cards.
The tables in this appendix provide the following data for each identified component.
Component Type
Three types of memory components are used on the server board assembly. These include:
•
Non-volatile: Non-volatile memory is persistent, and is not cleared when power is removed from the
system. Non-Volatile memory must be erased to clear data. The exact method of clearing these areas
varies by the specific component. Some areas are required for normal operation of the server, and
clearing these areas may render the server board inoperable.
•
Volatile: Volatile memory is cleared automatically when power is removed from the system.
•
Battery powered RAM: Battery powered RAM is similar to volatile memory, but is powered by a
battery on the server board. Data in Battery powered Ram is persistent until the battery is removed
from the server board.
Size
The size of each component includes sizes in bits, Kbits, bytes, kilobytes (KB) or megabytes (MB).
Board Location
The physical location of each component is specified in the Board Location column. The board location
information corresponds to information on the silkscreen in the server board.
User Data
The flash components on the server board do not store user data from the operating system. No operating
system level data is retained in any listed components after AC power is removed. The persistence of
information written to each component is determined by its type as described in the table.
Each component stores data specific to its function. Some components may contain passwords that provide
access to that device’s configuration or functi
onality. These passwords are specific to the device and are
unique and unrelated to operating system passwords. The specific components that may contain password
data are:
BIOS:
The BIOS provides the capability to prevent unauthorized users from configuring BIOS settings
when a BIOS password is set. This password is stored in BIOS flash, and is only used to set BIOS
configuration access restrictions.
BMC:
The server board supports an Intelligent Platform Management Interface (IPMI) 2.0 conformant
baseboard management controller (BMC). The BMC provides health monitoring, alerting and remote
power control capabilities for the server board. The BMC does not have access to operating system
level data.
The BMC supports the capability for remote software to connect over the network and perform
health monitoring and power control. This access can be configured to require authentication by a
password. If configured, the BMC will maintain user passwords to control this access. These
passwords are stored in the BMC flash.
The server board includes several components that can be used to store data. A list of those components is
included in Table 31.
