9.2.2 Integrated BMC Hardware
ASPEED AST2500 is the processor of server management subsystem, based on
ARM1176JZF-S 32-bit RISC CPU microcontroller.
The following functions are integrated into the component:
● Baseboard Management Controller (BMC) with peripherals
● Server-class Super I/O (SIO)
● Graphics controller
● Remote KVM redirection, USB media redirection, and HW Encryption
The eSPI/LPC interface to the host is used for SIO and BMC communication. The eSPI/LPC
Bus interface provides IPMI Compliant KCS and BT interfaces.
The PCI Express interface is mainly used for the graphics controller interface to communicate
with the host. The graphics controller is a VGA-compliant controller with 2D hardware
acceleration and full bus master support. The graphics controller can support up to
1920x1200 32bpp@60Hz resolution at high refresh rates. The PCI Express interface is also
used for BMC messaging to other system devices using MCTP protocol.
The USB 2.0 Hub interface is used for remote keyboard and mouse, and remote storage
support. BMC supports various storage devices such as CDROM, DVDROM, CDROM (ISO
image), floppy and USB flash disk. Any of the storage devices can be used as a boot device
