Physical components of an HACMP™ cluster
HACMP™ provides a highly-available environment by identifying a set of resources that are essential to uninterrupted processing, and by defining a protocol that nodes use to collaborate to ensure that these resources are available. HACMP™ extends the clustering model by defining relationships among cooperating processors where one processor provides the service offered by a peer, when the peer is unable to do so.
An HACMP™ Cluster is made up of the following physical components:
HACMP™ allows you to combine physical components into a wide range of cluster configurations, providing you with flexibility in building a cluster that meets your processing requirements. Shared disk with mirror shows an example of an HACMP™ cluster. Other HACMP™ clusters can look very different, depending on the number of processors, the choice of networking and disk technologies, and so on.
