Operating principle
Event logging
Records system events and alerts, such as hardware failures, system anomalies, etc., which can be viewed and processed through remote access software or other management tools.
Firmware updates
Continuously checks for new firmware versions and can be upgraded through remote access to improve BMC performance and functionality.
Remote access
Communicate with the management host via a network interface and supports various remote access protocols, such as SSH, Telnet, etc., as well as remote power control, hardware monitoring, system alerts, and other functions.
System monitoring
Continuously monitors the health of the system, including temperature, voltage, fan speed, and other hardware information, such as CPU utilization, memory usage, etc.

interface
PCIe
high-speed interface that provides faster data transfer rates than SATA. PCIe SSDs can be connected directly to the PCIe bus on the motherboard, offering significantly faster sequential read and write
NVMe
protocol designed specifically for modern, high-performance SSDs to connect them to a computer's motherboard. NVMe SSDs typically use the M.2 or U.2 form factors and offer significantly faster read and write speeds than traditional SATA SSDs.
SATA
most widely used interface for connecting SSDs to a computer's motherboard.
typically have a 2.5-inch form factor and offer sequential read and write speeds of up to 600 MB/s
form factor
2.5-inch
2.5” is the most common type of SSD and fits into most laptop or desktop computers.
M.2
It is available in various lengths to enable different SSD drive capacities; the longer the drive, the more NAND flash chips can be mounted on it leading to higher capacity drives.
U.2
looks like a 2.5” drive but is a bit thicker. It uses a different connector and sends data through the PCIe interface. U.2 SSD technology is typically reserved for high-end workstations, servers, and enterprise applications that need greater storage. It allows higher operating temperatures and is more favorable for transferring heat than the M.2 form factor.
mSATA
uses a compact form factor like M.2 but is not interchangeable. M.2 drives can support both SATA and PCIe interface options whereas mSATA only supports SATA. This form factor is designed for smaller form factor systems where space is limited.
