Updating the fru and sensor data recovery
The side-band LAN connection utilizes the board network interface controller (NIC).This solution is less expensive than a dedicated LAN connection but also has limited bandwidth.DCMI (Data Center Management Interface) is a similar standard based on IPMI but designed to be more suitable for Data Center management: it uses the interfaces defined in IPMI, but minimizes the number of optional interfaces and includes power capping control, among other differences.As well as using a separate dedicated management LAN connection, IPMI also allows implementation of a so-called "side-band" management LAN connection.
The BMC monitors the sensors and can send alerts to a system administrator via the network if any of the parameters do not stay within pre-set limits, indicating a potential failure of the system.
Highly integrated BMCs can provide complex instructions and provide the complete out-of-band functionality of a service processor.
The firmware implementing the IPMI interfaces is provided by various vendors.
For example, when a remote computer is down the system administrator can access it through IPMI and utilize a text console.
This suffices for a few vital functions, such as checking the event log, accessing the BIOS setup and performing power on, power off or power cycle.
