Patent Images
1. A system comprising:
- a hardware platform for supporting a service;
an availability management (AM) software entity which supports availability of said service, said AM software entity being distributed to include;
a first global availability management core (AMCg) portion, at a first hierarchical level, having a first set of AM functions associated therewith;
a first plurality of local AMC (AMCl) portions, at a second hierarchical level, having a second set of AM functions associated therewith; and
a first plurality of AMC components, at a third hierarchical level, which are supplied with said first and second sets of AM functions to support availability of said service; and
a first AM extension portion having a third set of one or more AM functions associated therewith, said first AM extension portion being a plug-in software entity located at said first hierarchical level and said third set of AM functions being mutually exclusive of said first and second sets of AM functions.
