Hardware Requirements - Intel S2600CO Family Technical Product Specification

Intel® Server Board S2600CO Family TPS
Following are the some of the applications of Intel
Platform Power Monitoring and Limiting: The ME/NM monitors platform power

consumption and hold 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, then 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, then 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.

Hardware Requirements

NM is supported only on platforms that have the NM FW functionality loaded and enabled on
the Management Engine (ME) in the SSB and that have a BMC present to support the external
LAN interface to the ME. NM power limiting features requires a means for the ME to monitor
input power consumption for the platform. This capability is generally provided by means of
PMBus-compliant power supplies although an alternative model using a simpler SMBus power
monitoring device is possible (there is potential loss in accuracy and responsiveness using non-
PMBus devices). The NM SmaRT/CLST feature does specifically require PMBus-compliant
power supplies as well as additional hardware on the baseboard.
