IBM Hardware Management Console
From Wikipedia, the free encyclopedia
Hardware Management Console is a technology invented by IBM for the purpose of providing a standard interface to configuring and operating partitioned (also known as an LPAR or virtualized system) and SMP systems.
Using a HMC, the system administrator is able to manage the software configuration and operation of partitions in a server system, as well as to monitor and identify hardware problems. HMCs offer an inexpensive method to administer complex and expensive servers, as a console need only consist of a 32-bit Intel-based desktop PC with a DVD-RAM drive.
