IBM High Availability Cluster Multiprocessing

From Wikipedia, the free encyclopedia

HACMP is IBM's solution for high-availability clusters on the AIX Unix and Linux for IBM System p platforms and stands for High Availability Cluster Multiprocessing. IBM's HACMP product was first shipped in 1991 and is now in its 16th release - HACMP 5.4

HACMP can run on up to 32 computers or nodes, each of which is either actively running an application (active) or waiting to take over should another node fail (passive). Data on file systems can be shared between systems in the cluster.

HACMP relies heavily on IBM's Reliable Scalable Cluster Technology (RSCT). RSCT is the foundation upon which HACMP and the General Parallel File System (GPFS) are built. For more information, visit IBM's HACMP documentation page: http://www-03.ibm.com/systems/p/library/hacmp_docs.html
