Management Engine; Intel 82801Jx I/O Controller Hub (Ich10R) - Intel S5500WB Technical Product Specification

Functional Architecture
®
The Intel 5500 Chipset IOH supports DMA remapping from inbound PCI Express* memory
Guest Physical Address (GPA) to Host Physical Address (HPA). PCI Express* devices are
directly assigned to a virtual machine leading to a robust and efficient virtualization.

Management Engine

The Management Engine (ME) is an embedded ARC controller within the IOH. The IOH ME
performs manageability functions called Intel
Baseboard Management Controller (BMC).
The functionality provided by the SPS firmware is different from Intel
®
Technology (Intel AMT or AT) provided by the ME on client platforms.
Server Platform Services are value-added platform management options that enhance the value
of Intel platforms and their component ingredients (CPUs, chipsets, and I/O components). Each
service is designed to function independently wherever possible, or grouped together with one
or more features in flexible combinations to allow OEMs (Original Equipment Manufacturers) to
differentiate platforms. The following is a high-level view of the Intel
SPS functions.
•
Node Management Features:
•
NPTM Policy Manager
•
Power Supply Monitoring Service
•
Inlet Temperature Monitoring Service
• CPU Power Limiting Service
• Provide Access to ICH10R Devices: The ME has control of ICH10R platform
instrumentation. SPS provides a mechanism for the BMC to access this instrumentation
through IPMI OEM commands. Use of this capability on Intel servers is platform-/SKU-
specific.
•
ICH10 temperature monitoring
•
PECI 2.0 Proxy: SPS offers a means for a BMC without a PECI 2.0 interface to use the ME
as a PECI proxy. The BMC on Intel servers already has a PECI 2.0 interface, so this SPS
capability is not used.
