                    Current Consumption field

                    The power currently being used by the server, in watts.

                    Maximum Consumption field

                    The maximum number of watts consumed by the server since the last time it was rebooted.

                    Minimum Consumption field

                    The minimum number of watts consumed by the server since the last time it was rebooted.

                    Minimum Configurable Limit field

                    The minimum amount of power that can be specified as the peak power cap for this server, in watts.

                    Maximum Configurable Limit field

                    The maximum amount of power that can be specified as the peak power cap for this server, in watts.


                    Power Capping Policy

                    The power capping policy determines how server power consumption is actively managed. When power capping is enabled, the system monitors how much power is allocated to the server and attempts to keep the power consumption below the allocated power. If the server exceeds its maximum allotment, the power capping policy triggers the specified non-compliance action.

                    Configuring the Power Capping Policy

                    Before You Begin

                    You must log in with admin privileges to perform this task.

                      Enable Power Capping check box

                      If this box is checked, the system monitors how much power is allocated to the server and takes the specified action if the server goes over its maximum allotment.

                      Peak Power field

                      The maximum number of watts that can be allocated to this server. If the server requests more power than specified in this field, the system takes the action defined in the Non-Compliance Action field

                      Enter a number of watts within the range defined by the Minimum Configurable Limit field and the Maximum Configurable Limit field.

                      Non-Compliance Action drop-down list

                      The action the system should take if power capping is enabled and the server requests more than its peak power allotment. This can be one of the following:

                      • Force Power Reduction—The server is forced to reduce its power consumption by any means necessary. This option is available only on some C-Series servers.
                      • None—No action is taken and the server is allowed to use more power than specified in the Peak Power field.
                      • Power Off Host—The server is shut down.
                      • Throttle—Processes running on the server are throttled to bring the total power consumption down.

                        • Power Off—The server remains off until it is manually restarted.
                        • Power On—The server is allowed to boot up normally when power is restored. The server can restart immediately or, optionally, after a fixed or random delay.
                        • Restore Last State—The server restarts and the system attempts to restore any processes that were running before power was lost.

                        Power Delay Type drop-down list

                        If the selected policy is Power On, the restart can be delayed with this option. This can be one of the following:

                        • fixed—The server restarts after a fixed delay.
                        • random—The server restarts after a random delay.

                        Power Delay Value field

                        If a fixed delay is selected, the number of seconds before the server is restarted after chassis power is restored.

                                    The amount of power available to the server components when they are idle. This can be one of the following:

                                    • C0 state—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.
                                    • C1 state—When the CPU is idle, the system slightly reduces the power consumption. This option requires less power than C0 and allows the server to return quickly to high performance mode.
                                    • C3 state—When the CPU is idle, the system reduces the power consumption further than with the C1 option. This requires less power than C1 or C0, but it takes the server slightly longer to return to high performance mode.
                                    • C6 state—When the CPU is idle, the system reduces the power consumption further than with the C3 option. This option saves more power than C0, C1, or C3, but there may be performance issues until the server returns to full power.
                                    • C7 state—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.
                                    • No Limit—The server may enter any available C state.
                                    Note   

                                    This option is used only if CPU C State is enabled.

                                    C1E

                                    Whether the CPU transitions to its minimum frequency when entering the C1 state. This can be one of the following:

                                    • Disabled—The CPU continues to run at its maximum frequency in C1 state.
                                    • Enabled—The CPU transitions to its minimum frequency. This option saves the maximum amount of power in C1 state.
                                    Note   

                                    This option is used only if CPU C State is enabled.

                                    How the memory reliability, availability, and serviceability (RAS) is configured for the server. This can be one of the following:

                                    • Maximum Performance—System performance is optimized.
                                    • Mirroring—System reliability is optimized by using half the system memory as backup.
                                    • Sparing—System reliability is enhanced with a degree of memory redundancy while making more memory available to the operating system than mirroring.

                                    NUMA Optimized

                                    Whether the BIOS supports NUMA. This can be one of the following:

                                    • Enabled—The BIOS includes the ACPI tables that are required for NUMA-aware operating systems. If you enable this option, the system must disable Inter-Socket Memory interleaving on some platforms.

                                    Low Voltage DDR Mode

                                    Whether the system prioritizes low voltage or high frequency memory operations. This can be one of the following:

                                    • Power Saving Mode—The system prioritizes low voltage memory operations over high frequency memory operations. This mode may lower memory frequency in order to keep the voltage low.
                                    • Performance Mode—The system prioritizes high frequency operations over low voltage operations.

                                    Sparing Mode

                                    The sparing mode used by the CIMC. This can be one of the following:

                                    • Rank Sparing—The spared memory is allocated at the rank level.
                                    • DIMM Sparing—The spared memory is allocated at the DIMM level.
                                    Note   

                                    This option is used only if Select Memory RAS is set to Sparing.

                                    Mirroring Mode

                                    Mirroring is supported across Integrated Memory Controllers (IMCs) where one memory riser is mirrored with another. This can be one of the following:

                                    • Intersocket—Each IMC is mirrored across two sockets.
                                    • Intrasocket—One IMC is mirrored with another IMC in the same socket.
                                    Note   

                                    This option is used only if Select Memory RAS is set to Mirroring.

                                    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.

                                    Patrol Scrub Interval

                                    Controls the time interval between each patrol scrub memory access. A lower interval scrubs the memory more often but requires more memory bandwidth.

                                    Select a value between 5 and 23. The default value is 8.

                                    Note   

                                    This option is used only if Patrol Scrub is set to Enabled.

                                    CKE Low Policy

                                    Controls the DIMM power savings mode policy. This can be one of the following:

                                    • Disabled—DIMMs do not enter power saving mode.
                                    • Slow—DIMMs can enter power saving mode, but the requirements are higher. Therefore, DIMMs enter power saving mode less frequently.
                                    • Fast—DIMMs enter power saving mode as often as possible.
                                    • Auto—The BIOS controls when a DIMM enters power saving mode based on the DIMM configuration.

                                    • Disabled—The BIOS does not generate an NMI or log an error when a SERR occurs.
                                    • Enabled—The BIOS generates an NMI and logs an error when a SERR occurs. You must enable this setting if you want to enable Assert NMI on PERR.

                                    Assert NMI on PERR

                                    Whether the BIOS generates a non-maskable interrupt (NMI) and logs an error when a processor bus parity error (PERR) occurs. This can be one of the following:

                                    • Disabled—The BIOS does not generate an NMI or log an error when a PERR occurs.
                                    • Enabled—The BIOS generates an NMI and logs an error when a PERR occurs. You must enable Assert NMI on SERR to use this setting.

                                    FRB2 Enable

                                    Whether the FRB2 timer is used by CIMC to recover the system if it hangs during POST. This can be one of the following:

                                    • Disabled—The FRB2 timer is not used.
                                    • Enabled—The FRB2 timer is started during POST and used to recover the system if necessary.

                                    PlugNPlay BMC Detection

                                    Whether the system automatically detects the BMC in ACPI-compliant operating systems. This can be one of the following:

                                    • Disabled—The system never automatically detects the BMC.
                                    • Enabled—The system automatically detects the BMC whenever possible.

                                    ACPI1.0 Support

                                    Whether the BIOS publishes the ACPI 1.0 version of FADT in the Root System Description table. This version may be required for compatibility with OS versions that only support ACPI 1.0. This can be one of the following:

                                    • Disabled—ACPI 1.0 version is not published.
                                    • Enabled—ACPI 1.0 version is published.

                                    Console Redirection

                                    Allows a serial port to be used for console redirection during POST and BIOS booting. After the BIOS has booted and the operating system is responsible for the server, console redirection is irrelevant and has no effect. This can be one of the following:

                                    • Disabled—No console redirection occurs during POST.
                                    • Serial Port A—Enables serial port A for console redirection during POST. This option is valid for blade servers and rack-mount servers.
                                    Note   

                                    If you enable this option, you also disable the display of the Quiet Boot logo screen during POST.

                                    Flow Control

                                    Whether a handshake protocol is used for flow control. Request to Send / Clear to Send (RTS/CTS) helps to reduce frame collisions that can be introduced by a hidden terminal problem. This can be one of the following:

                                    • None—No flow control is used.
                                    • RTS-CTS—RTS/CTS is used for flow control.
                                    Note   

                                    This setting must match the setting on the remote terminal application.

                                    Baud Rate

                                    What BAUD rate is used for the serial port transmission speed. If you disable Console Redirection, this option is not available. This can be one of the following:

                                    • 9.6k—A 9600 BAUD rate is used.
                                    • 19.2k—A 19200 BAUD rate is used.
                                    • 38.4k—A 38400 BAUD rate is used.
                                    • 57.6k—A 57600 BAUD rate is used.
                                    • 115.2k—A 115200 BAUD rate is used.
                                    Note   

                                    This setting must match the setting on the remote terminal application.

                                    Terminal Type

                                    What type of character formatting is used for console redirection. This can be one of the following:

                                    • PC-ANSI—The PC-ANSI terminal font is used.
                                    • VT100—A supported vt100 video terminal and its character set are used.
                                    • VT100-PLUS—A supported vt100-plus video terminal and its character set are used.
                                    • VT-UTF8—A video terminal with the UTF-8 character set is used.
                                    Note   

                                    This setting must match the setting on the remote terminal application.

                                    Legacy OS Redirection

                                    Whether redirection from a legacy operating system, such as DOS, is enabled on the serial port. This can be one of the following:

                                    • Disabled—The serial port enabled for console redirection is hidden from the legacy operating system.
                                    • Enabled—The serial port enabled for console redirection is visible to the legacy operating system.

                                    OS Boot Watchdog Timer

                                    Whether the BIOS programs the watchdog timer with a specified timeout value. If the operating system does not complete booting before the timer expires, the CIMC resets the system and an error is logged. This can be one of the following:

                                    • Disabled—The watchdog timer is not used to track how long the server takes to boot.
                                    • Enabled—The watchdog timer tracks how long the server takes to boot. If the server does not boot within the length of time specified in the OS Boot Watchdog Timer Timeout field, the CIMC logs an error and takes the action specified in the OS Boot Watchdog Policy field.

                                    OS Boot Watchdog Timer Timeout

                                    What timeout value the BIOS uses to configure the watchdog timer. This can be one of the following:

                                    • 5 Minutes—The watchdog timer expires 5 minutes after the OS begins to boot.
                                    • 10 Minutes—The watchdog timer expires 10 minutes after the OS begins to boot.
                                    • 15 Minutes—The watchdog timer expires 15 minutes after the OS begins to boot.
                                    • 20 Minutes—The watchdog timer expires 20 minutes after the OS begins to boot.
                                    Note   

                                    This option is only applicable if you enable the OS Boot Watchdog Timer.

                                    OS Boot Watchdog Policy

                                    What action the system takes if the watchdog timer expires. This can be one of the following:

                                    • Power Off—The server is powered off if the watchdog timer expires during OS boot.
                                    • Reset—The server is reset if the watchdog timer expires during OS boot.
                                    Note   

                                    This option is only applicable if you enable the OS Boot Watchdog Timer.

                                    Common Controls

                                    The buttons described in the following table are available in all Configure BIOS Parameters tabs.

                                    Name Description
