5. NUMA Optimized
Option Values:
Enabled
Disabled
Help Text:
If enabled, BIOS includes ACPI tables that are required for NUMA-aware Operating
Systems.
Comments: This option is only present for boards which have two or more processor
sockets. When a multi-socket board has only a single processor installed, this option is
grayed out and set as Disabled.
When enabled, the SRAT and SLIT ACPI tables are provided that show the locality of
systems resources, especially memory, which allows a “NUMA Aware” OS to optimize which
processor threads are used by processes which can benefit by having the best access to
those resources.
Mass Storage Controller Configuration
The Mass Storage Configuration screen allows the user to configure the Mass Storage controllers
that are integrated into the server board on which the BIOS is executing. This includes only
onboard Mass Storage controllers. Mass Storage controllers on add-in cards are not included in this
screen, nor are other storage mechanisms such as USB-attached storage devices or Network
Attached Storage.
There are two types of onboard controller configured in this screen, the AHCI SATA controller and
the Storage Control Unit (SCU) with SATA or SAS drive support and RAID support. There are
also informational displays of AHCI and SCU controller configuration, and SATA Drive
Information when applicable. If the presence of an Intel
®
Storage Module is detected, the type of
Storage Module is displayed as information-only.
To access this screen from the Main screen, select Advanced > Mass Storage Controller
Configuration. To move to another screen, press the <Esc> key to return to the Advanced screen,
then select the desired screen.
