Intel® Server Board S1200SP Family Technical Product Specification
Platform Power Monitoring and Limiting: The ME/NM monitors platform power consumption and holds
•
average power over duration. It can be queried to return actual power at any given instance. The power
limiting capability is to allow external management software to address key IT issues by setting a power
budget for each server. For example, if there is a physical limit on the power available in a room, IT can
decide to allocate power to different servers based on their usage – servers running critical systems can
be allowed more power than servers that are running less critical workload.
Inlet Air Temperature Monitoring: The ME/NM monitors server inlet air temperatures periodically. If there
•
is an alert threshold in effect, ME/NM issues an alert when the inlet (room) temperature exceeds the
specified value. The threshold value can be set by policy.
Memory Subsystem Power Limiting: The ME/NM monitors memory power consumption. Memory power
•
consumption is estimated using average bandwidth utilization information
Processor Power monitoring and limiting: The ME/NM monitors processor or socket power consumption
•
and holds average power over duration. It can be queried to return actual power at any given instant. The
monitoring process of the ME will be used to limit the processor power consumption through processor
P-states and dynamic core allocation.
Core allocation at boot time: Restrict the number of cores for OS/VMM use by limiting how many cores
•
are active at boot time. After the cores are turned off, the CPU will limit how many working cores are visible
to BIOS and OS/VMM. The cores that are turned off cannot be turned on dynamically after the OS has
started. It can be changed only at the next system reboot.
Core allocation at run-time: This particular use case provides a higher level processor power control
•
mechanism to a user at run-time, after booting. An external agent can dynamically use or not use cores in
the processor subsystem by requesting ME/NM to control them, specifying the number of cores to use or
not use.
