Intel Turbo Boost Technology
|
Whether
the processor uses Intel Turbo Boost Technology, which allows the processor to
automatically increase its frequency if it is running below power, temperature,
or voltage specifications. This can be one of the following:
|
|
Enhanced Intel Speedstep Technology
|
Whether
the processor uses Enhanced Intel SpeedStep Technology, which allows the system
to dynamically adjust processor voltage and core frequency. This technology can
result in decreased average power consumption and decreased average heat
production. This can be one of the following:
-
Disabled—The processor never dynamically adjusts its
voltage or frequency.
-
Enabled—The processor utilizes Enhanced Intel
SpeedStep Technology and enables all supported processor sleep states to
further conserve power.
We
recommend that you contact your operating system vendor to make sure the
operating system supports this feature.

This can be one of the following:
We
recommend that you contact your operating system vendor to make sure the
operating system supports this feature.
|
|
Number of Enabled Cores
|
Sets the
state of logical processor cores in a package. If you disable this setting,
Hyper Threading is also disabled. This can be one of the following:
-
All—Enables multi processing on all logical
processor cores.
-
1 through
n—Specifies the number of logical processor cores that
can run on the server. To disable multi processing and have only one logical
processor core running on the server, select
1.
We
recommend that you contact your operating system vendor to make sure the
operating system supports this feature.
|
|
Execute Disable
|
Classifies memory areas on the server to specify where
application code can execute. As a result of this classification, the processor
disables code execution if a malicious worm attempts to insert code in the
buffer. This setting helps to prevent damage, worm propagation, and certain
classes of malicious buffer overflow attacks. This can be one of the following:
We
recommend that you contact your operating system vendor to make sure the
operating system supports this feature.

be one of the following:
|
|
Intel VT-d PassThrough DMA
|
Whether
the processor supports Intel VT-d Pass-through DMA. This can be one of the
following:
|
|
Direct Cache Access
|
Allows
processors to increase I/O performance by placing data from I/O devices
directly into the processor cache. This setting helps to reduce cache misses.
This can be one of the following:
|
|
Processor C3 Report
|
Whether
the processor sends the C3 report to the operating system. This can be one of
the following:
-
Disabled—The processor does not send the C3 report.
-
—The processor sends the C3 report using the
ACPI C2 format.
-
—The processor sends the C3 report using the
ACPI C3 format.
|
|
Processor C6 Report
|
Whether
the processor sends the C6 report to the operating system. This can be one of
the following:
|
|
Hardware Prefetcher
|
Whether
the processor allows the Intel hardware prefetcher to fetch streams of data and
instruction from memory into the unified second-level cache when necessary.
This can be one of the following:
|
Note
|
You
must select
Custom in the
to specify this value.
For any value other than
Custom, this option is overridden by the setting in
the selected CPU performance profile.
|
|
|
Adjacent Cache-Line Prefetch
|
Whether
the processor uses the Intel Adjacent Cache-Line Prefetch mechanism to fetch
data when necessary. This can be one of the following:
|
Note
|
You
must select
Custom in the
in order to specify
this value. For any value other than
Custom, this option is overridden by the setting in
the selected CPU performance profile.
|
|
|
Boot Option Rom
|
Sets the ROM type. This can be one of the following:
-
Legacy—The server launches the legacy Option ROM.
-
UEFI—The server launches the legacy UEFI ROM.
-
Disabled—Option ROM is not available.
|
|
Package C State Limit
|
The
amount of power available to the server components when they are idle. This can
be one of the following:
-
—The
server provides all server components with full power at all times. This option
maintains the highest level of performance and requires the greatest amount of
power.
-
—
System level coordination is in progress resulting in high power consumption.
There might be performance issues until the coordination is complete.
-
—When
the CPU is idle, the system reduces the power consumption further than with the
C3 option. This option saves more power than C0 or C2, but there might be
performance issues until the server returns to full power.
-
—When
the CPU is idle, the server makes a minimal amount of power available to the
components. This option saves the maximum amount of power but it also requires
the longest time for the server to return to high performance mode.
-
—The
server may enter any available C state.
|
Note
|
This
option is used only if
CPU C State is enabled.
|
|
|
Boot Order Rules
|
Whether the system boots according to the boot order that is specified in CIMC or specified in the BIOS setup utility. This
can be one of the following:
|
|
Patrol Scrub
|
Whether
the system actively searches for, and corrects, single bit memory errors even
in unused portions of the memory on the server. This can be one of the
following:
-
Disabled—The system checks for memory ECC errors
only when the CPU reads or writes a memory address.
-
Enabled—The system periodically reads and writes
memory searching for ECC errors. If any errors are found, the system attempts
to fix them. This option may correct single bit errors before they become
multi-bit errors, but it may adversely affect performance when the patrol scrub
is running.
|
|
Demand Scrub
|
Whether
the system allows a memory scrub to be performed on demand. This can be one of
the following:
-
Disabled—The system does not allow a memory scrub to
be performed on demand.
-
Enabled—The system allows a memory scrub to be
performed on demand. If errors occur, the system attempts to fix them or marks
the location as unreadable. This process makes the system run faster with fewer
data processing errors.
|
|
Device Tagging
|
Whether
the system allows devices and interfaces to be grouped based on a variety of
information, including descriptions, addresses, and names. This can be one of
the following:
|
|
PXE Boot Mode
|
Configures the network ports for PXE boot according to the mode configured by the user. The following options are available:
-
Legacy: enables legacy PXE on the network ports. This is valid only if UEFI secure boot is disabled.
-
UEFI: enables UEFI PXE on the network ports.
-
Disabled: PXE is disabled and will not enable the ports to check for any PXE installation.
PXE boot mode is supported in BIOS v2.13 and later.
|
Note
|
If you are running ESXi 7.0 (or later), the ESXi backplane vmnic’s require PXE boot mode to be configured to the appropriate
mode in BIOS. If PXE boot mode is not configured correctly, thebackplane vmnic’s will not come up.
