Out-of-band management

Мониторинг через дополнительные каналы, а не через те, которыми подключено устройство. rs232, по-идее, является один из таких способов

Server Management

ipmi Intelligent Platform Management Interface

smb System Management Bus

у Dell это называется Dell DRAC link

bios, frusdr (Field Replaceable Unit/Sensor Data Record), bmc (Baseboard management controller), hsc (Hot Swap Controller)

To aid in fault isolation, a unit called a Field Replaceable Unit IDentifier (FRU ID) holds the records of the devices that do not originally come with the baseboard or motherboard. Most (though not all) board manufacturers use EEPROM to store FRU IDs, which play a significant role in IPMI. The BMC contacts the FRU devices whenever there is a problem in the hardware to determine the device to replace. Most often, the BMC communicates with the FRU using the I²C bus protocol, but can also use other implementation-specific protocols.

 HP ProLiant uses: - the SmartArray (drivers/modules/something), most of them supported - NIC, which is de-facto Broadcom or Intel - iLO, which is not supported - Server management, not supported

Right now in FreeBSD is waste of support: - for array reconfiguration utility (on the fly, I used it many times in Win/Novell world) - server health monitoring (HP allow as many other vendors monitoring of server health) - Remote console and media support (HP iLO)

But similar situation are for other vendors too. People who trying to solve this issue are overloaded and they do as much as possible, but most of their work is investigation due lack of documentation and resources.
