Clustering
support
Clustering
is
a
means
of
sharing
array
groups
among
controllers
to
provide
redundancy
of
controllers
and
servers.
This
redundancy
is
important
if
a
hardware
component
fails.
If
a
hardware
component
failure
occurs
in
a
cluster,
another
server
takes
ownership
of
the
array
group.
Clustering
requires
software
specific
to
your
operating
system.
