Intelligent Platform Management Interface
(IPMI) is a remote hardware health monitoring

for use in monitoring the physical health of serv-

supplies and chassis. It was developed by Dell,
HP, Intel and NEC, but has now been adopted
by more than 150 server technology and ships

functionality let network managers access and
monitor server hardware, and diagnose and
restore a frozen server to normal operation.
