CHAPTER 3 Component Configuration and Replacement (Add, Remove)
3.2 High availability configuration
- Power Technology
- Enhanced SpeedStep
- Turbo Mode
- Energy Performance
- P-State Coordination
- QPI Link Frequency Select
- Frequency Floor Override
- DIMM Speed setting
- Select the action of Extended Partitioning from following actions after the Watchdog timeout is detected.
- Continue
- Reset
- NMI
- Power Cycle (*1)
*1: The 'Power Cycle' of Extended Partitioning executes control in the same way as reset.
- For the memory setting, the setting of the Physical partition is also applicable to the Extended Partition.
Setting cannot be carried out in the Extended Partition.
- Memory Operation Mode
- Memory Mirror RAS Mode
- Patrol Scrub (set in the UEFI menu)
- Although the physical partition incorporating the Reserved SB maintains the configuration information of
previous Extended Partition, the hardware resources may vary from the SB prior to the degradation.
- Extended Partitioning is supported in CPU core degradation / memory degradation and spare CPU core /
spare memory. If there is error in the CPU core / memory, and degradation occurs during Extended
Partitioning startup, Extended Partitioning will first attempt to use the reserve CPU core / reserve memory
(*1), and if the allocated resources are still insufficient, CPU core degradation / memory degradation will
occur.
*1: Free CPU core / memory that is not allocated to the Extended Partition
- If there is a spare CPU core / spare memory:
Extended Partition is initialized by using the spare CPU core / spare memory in place of the failed
CPU core / memory.
- If there is not a spare CPU core / spare memory, or if the spare CPU core / spare memory is
insufficient:
The allocated CPU core / memory is reduced and the Extended Partition is initialized, and the order of
priority of the CPU core / memory allocation when multiple Extended Partitions startup, will be in the
ascending order of partition number.
When there is no locatable CPU core / memory, the Extended Partitioning firmware will detect
configuration error.
The Extended Partition does not start.
- In Extended Partitioning, sadump can be used in the Extended Partitioning-BIOS, and the operating
system hierarchy. Dump of Extended Partitioning firmware hierarchy cannot be taken.
- An Extended Partition takes longer time to access devices which are shared among other Extended
Partitions than occupied by only the Extended Partition. Hence, performance depends on pattern in which
the application accesses the device.
- If such below massage appears at OS boot, system operation is not affected.
"Jul 5 23:05:32 localhost kernel: TSC: HPET/PMTIMER calibration failed."
- When an Extended Partition number is removed from a physical partition in Partition Configuration
window, hardware resources assigned to the Extended Partition are freed but its BIOS settings are
reserved.
So if the same Extended Partition number is assigned to the same physical partition again, the reserved
BIOS settings of the Extended Partition are restored.
