with
RAID
capabilities
supports
the
following
features:
–
Integrated
Mirroring
(IM)
with

support
(also
known
as
RAID
1)
Use
this
option
to
create
an

v
Hard
disk
drive
capacities
affect
how
you
create
arrays.
The
drives
in
an
array
can
have
different
capacities,
but
the
RAID
controller
treats
them
as
if
they
all
have
the
capacity
of
the
smallest
hard
disk
drive.
v
If
you
use
an
integrated
SAS/SATA

a
RAID
1
(mirrored)
array

have
installed
the
operating
system,
you
will
lose
access
to
any

or
applications
that

previously
stored
on
the
