4.5.3 Optimal Power Allocation
The PRIMEQUEST 2000 series is equipped with the optimal power allocation function that varies the
number of active power supply units according to the system configuration. Optimal Power Allocation keeps
the power supply highly efficient.
The Optimal Power Allocation function is always enabled. Optimal power allocation has the following two
functions.
-
Operating-PSU optimization
It controls the number of active PSUs depending on the quantity of powered on hardware resources.
-
Operating-DDC optimization
It controls the number of active DDCs depending on the number of CPUs mounted in the SB.
4.5.4 Scheduled Operations
The PRIMEQUEST 2000 series can schedule the power-on/off time of each partition from the MMB, and can
also control automatic operations according to the schedule.
The scheduled operations and the power restoration function are linked when power restoration mode is set
to ‘Schedule Sync.’.
For details, see ‘9.3 Scheduled operations’ of the
PRIMEQUEST 2000 Series Administration Manual
(CA92344-0537)
4.5.5 Remote Power Supply Operations
The PRIMEQUEST 2000 series can control the power supply through connections to partitions from a
remote terminal using the MMB Web-UI.
Power supply operation by WOL function is also available.
Both IOU_1GbE and IOU_10GbE support WOL.
Remarks
The support for WOL depends on the OS. Refer to each OS manual for details.
4.5.6 UPS
Uninterruptible Power System (UPS) is an external battery unit. With a UPS connected, the device can be
prepared for a power failure or sudden power supply fluctuation.
The UPS of the PRIMEQUEST 2000 series is a SMART UPS. Shut down is instructed from PowerChute by
the LAN connection.

Clock feature
This section describes the Clock feature of the PRIMEQUEST 2000 series.
4.6.1 MMB, BIOS and BMC Time Management
This section describes the MMB, BIOS/OS and BMC time management of the PRIMEQUEST 2000 series;
this is separately done as shown below.
MMB
The MMB has an RTC and manages the time of the day independently. The RTC can be set by a user.
Notes
The MMB time and the partition time are managed separately by independent clocks.
The MMB clock does not report or adjust the time of the partition clock. Keep the MMB time and the partition
time the same, or at least close, as they are needed for the following cases.
-
When checking the MMB log against the OS log in a partition when there is a the hardware failure
-
When conducting a system audit or security audit
-
When an error occurs in time maintenance battery in a partition
Use either of the following ways to adjust the times.
-
Adjusting the time manually from the MMB Web-UI
