A given computer in a cluster communicates with multiple computers in the
cluster i) via use of a network supporting communications from the
multiple computers amongst each other, and ii) through accesses to the
shared storage system to which each of the computers in the cluster have
access. Each computer in the cluster i) supports communications over a
network connection to the other computers and ii) includes a link (e.g.,
a fiber channel) directly to the shared storage system. Thus, if one
communication path fails such as the network path, the other
communication path such as the independent link to the shared storage
supporting the ability to read/write to storage provides a backup means
of communicating. Attributes associated with a cluster can therefore be
properly maintained via the members even during a failure.
