IPMI
IPMI (Intelligent Platform Management Interface) is a hardware-level interface
specification that provides remote access, monitoring and administration for
Supermicro server platforms. IPMI allows server administrators to view a server's
hardware status remotely, receive an alarm automatically if a failure occurs, and
power cycle a system that is non-responsive.

Server Chassis Features
Some features of the SC227HD-R1K28 chassis are listed below.
System Power
The system features two high-efficiency, hot-plug, 80 Plus Platinum level, digital
1280W redundant power supplies. One power module may be removed without
shutting down the system. See Chapter 6 for details.
Drive Bays
The chassis includes twenty 2.5" drive bays and four dummy bays to allow for
cooling. Each node can control eight hot-swappable SATA or SAS drives and two
NVMe (Non Volatile Memory Express) drives. .
Front Control Panel
Two control panels provide on the front of the chassis a system monitoring and
control interface for each computing node. LEDs indicate network activity, system
overheat, UID and power supply failure. A main power button and a UID button
are also included.
Cooling System
The chassis has an innovative cooling design that includes four 4-cm PWM (Pulse
Width Modulated) fans and an air shroud to focus airflow where it is needed. The
power supply module also includes a cooling fan. All fans operate continuously.
The CPU and chassis fan speeds are controlled by IPMI Thermal Management. A
thermal control sensor monitors the CPU temperature in real time and controls fan.
The chassis thermal circuitry monitors the overall system temperature and alerts
when the chassis temperature is too high.
