Chapter 1: Overview

1-6 BMC Controller
The BMC Controller (ASpeed AST2500 chip) provides a high-speed, 16550 compat-
ible serial communication port (UART), which supports serial infrared communica-
tion. The UART includes send/receive FIFO, a programmable baud rate generator,
complete modem control capability, and a processor interrupt system. The UART
provides legacy speed with baud rate of up to 115.2 Kbps as well as an advanced
speed with baud rates of 250 K, 500 K, or 1 Mb/s, supporting higher speed modems.
The BMC Controller provides functions that comply with ACPI (Advanced Con-
figuration and Power Interface), which includes support of legacy and ACPI power
management through a SMI or SCI function pin. It also features auto power man-
agement to reduce power consumption.
1-7 SAS/SATA I/O controller
The P9DSU-C motherboard integrates the Microsemi PM8069 SSCi SAS/SATA
controller which supports RAID 0, 1, 5, 10. It supports up to 8 lanes of PCI-E
3.0 with each lane supporting transfer rates of up to 8.0Gbps. Furthermore, it can
support up to 8 lanes of 1.5G/3G/6G SATA or 3G/6G/12G SAS. It has a flexible
configuration for HBA and supports up to 238 SAS/SATA devices. Please visit the
Microsemi website for more information.
1-8 Serial Port
The P9DSU-C motherboard supports one serial communication connection. COM
Port 1 can be used for input/output. The UART provide legacy speed with baud
rate of up to 115.2 kbps, which support system console message for the system
status monitoring.
