Manageability Engine (ME)
The Manageability Engine, which is an ARC controller embedded in the IOH (I/O
Hub), provides Server Platform Services (SPS) to your system. The services
provided by SPS are different from those proveded by the ME on client platforms.
1-8 Introduction to the BMC (Baseboard Management
Controller)
This motherboard incorporates the ASPEED AST2400 Graphics and BMC.
The AST2400 is ASPEED's 5th generation of Advanced PCIe Graphics & Remote
Management Processor, with a mainstream double data rate memory migrating from
DDR2 to DDR3. The AST2400, provides the motherboard with DDR3 support, with
the best cost/performance ratio. The AST2400 is integrated with PCIe 1x support.
In addition to the the AST2400's advanced BMC features. The chip's PCIe 2D
VGA provides servers with a local display, without the added cost and with minimal
pin counts. The embedded ARM9 and DDR3 is clocked at 400MHz to meet the
increasing performance requirements of today's server applications.
