CHAPTER 1 Product Overview
1.4 Hardware technologies

1.4.28 Active Processor Cores Function

The PRIMEQUEST 2000 series supports Active Processor Cores
Active Processor Cores limits the number of cores for specific physical partition.
Active Processor Cores is also called as Core Disabling or Logical Processor Disable.
Active Processor Cores is configured by the UEFI.
The default value is 'All Cores Enabled'.
Default value
Minimum number of enabled cores
Specifying enabled cores
Hyper Thread setting
Note
The setting that Hyper Thread is made enabled or disabled is applied to all active cores of all CPU in the
partition.
For details, see '3.4.4 [CPU Configuration] Menu' in "PRIMEQUEST 2000 Series Tool Reference"
(CA92344-0539).
1.4.29 Optimal Fan Control Cooling (Optimization of rotation per minute
of fans)
The PRIMEQUEST 2000 series supports Optimal Fan Control Cooling function.
This function optimizes fan rotational speed so that system is cooled efficiently while reducing power
consumption.
Optimal Fan Control Cooling function below:
- Determines the rpm of the fan, considering both the Ambient and the Component temperature of the
place where the system is set and configuration pattern of the system.
- There is the concept of cooling group in a cabinet, which controls fan rotational speed for each group.
For details on cooling, see

1.4.30 Air Flow Monitoring

The PRIMEQUEST 2000 series supports the Air Flow Monitoring function.
The Air Flow Monitoring provides the following functions.
- The exhaust volume is displayed in the MMB Web-UI
- The exhaust volume is notified to the higher level software through the SNMP.
1.4.31 Optimal Power Allocation (Optimization of the number of
operation power sources)
The PRIMEQUEST 2000 series supports Optimal Power Allocation as one of the energy saving functions.
The following operations are performed in Optimal Power Allocation.
- Optimization of the number of operating PSUs
Changing the number of operating PSUs based on the configuration of the device.
- Optimization of the number of operating DDCs
Changing the number of operating DDCs based on the number of CPUs mounted in the SB.
Optimal Power Allocation operates automatically according to the configuration of the device. There is no
screen for setting.
Remarks
If redundantly configured PSU turns non-redundant due to PSU failure, Optimal Power Allocation does not
operate.
